Most articles tell you the Baltic Dry Index measures dry bulk shipping rates. That is technically correct and practically useless on its own.
What those articles skip: which subindex to watch for iron ore signals, why Capesize and Panamax can move in opposite directions on the same day, or how FFA brokers use these numbers to settle billions in freight derivatives every month.
I work with these indices daily as a chartered shipbroker and as CCO of Shipfinex. This is the version written from that desk.
Who this guide is for: Shore-based maritime professionals, shipbrokers, senior seafarers, shipping finance professionals, and anyone who needs to understand what BDI actually signals rather than what it is defined as.
Quick Answer: The Baltic Dry Index (BDI) is a daily shipping cost index published by the Baltic Exchange in London. It combines time charter rate assessments for Capesize (40%), Panamax (30%), and Supramax (30%) vessels across 20 ocean routes, submitted daily by an international panel of shipbrokers. It carries no speculative component.
What Is the Baltic Dry Index and Who Publishes It
Think of the BDI as a daily price check for the global flow of raw materials. When a Chinese steel mill needs iron ore from Australia, a power plant needs coal from Indonesia, or a grain trader needs to move wheat out of the US Gulf, the cost of hiring a vessel to do that job gets recorded. The BDI aggregates those costs into a single daily number.
The Baltic Exchange in London publishes it. The Exchange started in 1744, when merchants involved in Baltic Sea trade gathered at the Virginia and Baltick Coffee House on Threadneedle Street to exchange shipping information and close deals. By 1823 it had a formal committee structure. In January 1985, it published the first Baltic Freight Index (BFI), the direct predecessor of today’s BDI. The BFI became the Baltic Dry Index in November 1999.
The BDI is not a single price. It is a weighted composite of three vessel-class time charter rate averages, each representing a different segment of the dry bulk shipping market.
The Baltic Exchange’s Role in Freight Markets
The Baltic Exchange is more than an index publisher. It is a membership organization that sets professional conduct standards for shipbrokers and charterers worldwide, compiles daily freight data across dry bulk, tanker, gas, container, and air cargo markets, governs the settlement of freight derivatives contracts, and validates the panellist submissions that underpin every index it publishes.
This governance role matters commercially. Because Baltic Exchange assessments are used to settle freight forward agreements (FFAs) worth hundreds of millions of dollars every month, the accuracy of every daily submission has real financial consequences. The Exchange has independent oversight, audit processes, and a benchmark administration framework that make it one of the most credible price-discovery mechanisms in global commodity markets.
Why BDI Covers Dry Bulk Specifically
Dry bulk cargo is any commodity shipped in loose, unpackaged form in the holds of a bulk carrier. The main dry bulk commodities are iron ore, coal, grain, bauxite, phosphate, and fertilizer. Each vessel typically carries a single commodity on a single voyage.
This matters for price discovery. Dry bulk trades are commodity-specific and ship-specific, so the rate a shipowner charges reflects actual supply and demand for that commodity movement, not a blend of different packaging types or value-added services. There is no brand premium, no last-mile complexity. Tonnes moved between two ports. That clarity is why BDI can function as a relatively clean economic signal.
Wet bulk (crude oil, refined products) has its own Baltic Exchange indices: the Baltic Dirty Tanker Index (BDTI) and Baltic Clean Tanker Index (BCTI). Containerized goods have the Freightos Baltic Index (FBX). BDI covers only dry bulk.
Index | What It Covers | Published By |
BDI (Baltic Dry Index) | Dry bulk: iron ore, coal, grain | Baltic Exchange |
BDTI / BCTI | Crude oil and refined product tankers | Baltic Exchange |
FBX | Global container spot rates | Freightos / Baltic Exchange |
HARPEX | Container charter rates | Harper Petersen |
How the BDI Is Actually Calculated: Panellist Mechanics
This is the section most articles skip. Understanding the mechanics tells you both how reliable the index is and where its edges are.
The Panellist Submission Process
Every working day, an approved international panel of shipbrokers submits their assessment of current freight rates on each of the 20 designated routes. Panellists are member firms of the Baltic Exchange. They are professional shipbrokers with active market positions, not analysts sitting at a desk reading news. Their submissions reflect what they believe the market would actually pay at that moment for a specific vessel type on a specific route.
The process, step by step:
1. Panellist firms submit their daily rate assessments for each designated route
2. Baltic Exchange staff review submissions and remove statistical outliers
3. Valid submissions are averaged per route to produce the route assessment
4. Route assessments are aggregated into each of the three vessel-class subindices: BCI, BPI, and BSI
5. The three subindices are combined using fixed weightings (40% Capesize, 30% Panamax, 30% Supramax) to produce BDI
6. The final BDI number is published daily around midday London time
What the panellist submits is not a transaction price. It is a professional judgment. This is the same mechanism used in LIBOR and similar benchmark rates. The difference is that Baltic Exchange panellists are shipbrokers actively fixing or being asked to fix vessels on these routes, which grounds their submissions in current market reality rather than theoretical pricing.
The 20 Routes and How They Are Selected
The 20 routes are not arbitrary. They represent the highest-volume, most commercially significant dry bulk trade lanes in the global market. Capesize routes track the major iron ore and coal corridors: West Australia to Qingdao, Tubarao (Brazil) to Rotterdam, China-Brazil round voyage. Panamax routes cover grain season trades out of the US Gulf and transatlantic round voyages. Supramax routes capture smaller commodity flows and shorter haul movements.
Vessel Class | DWT Range | Key Routes | Primary Cargo |
Capesize (BCI) | 120,000 to 400,000 | West Australia to Qingdao, Tubarao to Rotterdam, China-Brazil round | Iron ore, coal |
Panamax (BPI) | 60,000 to 120,000 | Transatlantic round, HK-South Korea Pacific round, US Gulf grain season | Coal, grain |
Supramax (BSI) | 40,000 to 65,000 | US Gulf to China, North China to West Africa, Canakkale to Far East | Grain, fertilizer, minor bulk |
The 2018 Methodology Change and Why It Mattered
In March 2018, following a consultation with Baltic Exchange members, the Handysize vessel class was removed from BDI. The new weighting became 40% Capesize, 30% Panamax, and 30% Supramax. The rationale: external analysis of fleet composition, vessel utilization, and total cargo moved confirmed that Handysize contributed roughly 10% of dry bulk market activity. Removing it made statistically negligible difference to the index calculation while simplifying the methodology.
The practical consequence for market professionals is that post-2018 BDI readings carry increased Capesize weighting relative to pre-2018 history. BDI is now more sensitive to iron ore and coal demand cycles. When you compare current BDI levels against 2010-era readings, that compositional shift is worth holding in mind.
The Three Subindices: What BCI, BPI, and BSI Each Measure
Practitioners do not watch BDI as a single number. They watch the subindices. This is where the commercially useful information lives.
Baltic Capesize Index (BCI): The Iron Ore and Coal Signal
Capesize vessels are the largest class in the dry bulk fleet, ranging from 120,000 to 400,000 deadweight tonnes (DWT). They are too wide for the Panama Canal. They operate on point-to-point bulk corridors, primarily carrying iron ore from Australia or Brazil to China, Japan, and South Korea, and thermal coal from Australia and Indonesia to Asian power markets.
BCI is the most volatile of the three subindices. When BCI rises sharply, it typically reflects one of three things: increased demand from Chinese steel mills restocking iron ore, a surge in coal demand from Asian power markets, or a supply-side constraint such as port congestion at major Chinese discharge ports reducing effective fleet availability. When BCI turns negative (it has done so briefly in 2015 and 2016), owners are absorbing operating losses to keep ships moving rather than paying lay-up costs.
BCI is the first subindex to move when a Chinese infrastructure cycle accelerates. It also overshoots sharply in both directions because the Capesize fleet has the least route flexibility of any vessel class.
Baltic Panamax Index (BPI): The Grain Season Bellwether
Panamax vessels (60,000 to 120,000 DWT) were originally sized to transit the original Panama Canal locks. They carry coal and grain as their primary cargoes. BPI is often the most seasonally predictable of the three subindices.
Between September and February each year, US Gulf grain export volumes peak as the US harvest moves to export terminals. Black Sea and South American grain exports add further demand. During this window, Panamax vessel demand from grain traders increases, and BPI typically outperforms BCI and BSI on a relative basis.
When BPI leads BDI upward while BCI is flat or lagging, the correct interpretation is a grain cycle, not a China infrastructure cycle. The policy implication for a charterer fixing grain voyages is very different from the implication for a steel mill trading iron ore. Most general BDI commentary does not make this distinction. It should.
Baltic Supramax Index (BSI): Versatility and Minor Bulk
Supramax vessels (40,000 to 65,000 DWT) are the workhorses of dry bulk. They access a far wider range of ports than Capesize or Panamax vessels, and carry a broader commodity mix: grain, fertilizer, steel products, petcoke, cement, and other minor bulk commodities.
BSI is the smoothest of the three subindices. It does not produce the dramatic spikes and collapses of BCI. When BSI diverges significantly from BCI, it usually means a vessel deployment mismatch rather than a broad demand shift. If BSI is holding up while BCI falls, the smaller bulk commodity markets are absorbing tonnage displaced from the iron ore trade. If BSI falls sharply while BCI holds, port-specific or route-specific issues are likely at play in the Supramax segment.
Subindex | BDI Weight | Volatility | Primary Demand Driver | Best Signal For |
BCI (Capesize) | 40% | Highest | China steel production, iron ore imports | Iron ore and coal demand cycles |
BPI (Panamax) | 30% | Medium | Agricultural export seasons | Grain trades, US Gulf and Black Sea activity |
BSI (Supramax) | 30% | Lowest | Minor bulk, fertilizer, steel products | Port flexibility demand, smaller commodity flows |
Reading the Subindices: What a 200-Point BCI Move Actually Means
Here is what no other article on this topic attempts: translating index point movements into commercial terms.
Converting Index Points to Daily Hire Rates
The BDI number is an index, not a dollar rate. But the underlying subindex assessments are quoted in USD per day. As a working approximation: when BCI trades at 2,000 points, the time charter equivalent hire rate for a standard Capesize vessel runs roughly in the range of $15,000 to $20,000 per day, depending on route and market conditions. At BCI 5,000, that hire rate is closer to $35,000 to $45,000 per day. At the 2008 peak of BCI above 10,000, Capesize hire rates exceeded $200,000 per day on some routes.
A 200-point move in BCI, at current market levels around 2,000 to 2,500, represents roughly a $1,500 to $2,500 daily hire rate change for a Capesize vessel. For an owner running a five-ship Capesize fleet on 12-month time charters, a sustained 200-point BCI move up or down translates to several million dollars in annual revenue difference. Capesize owners and charterers watch BCI every day, not BDI.
Professionals track BCI alongside the actual TCE assessments published by the Baltic Exchange rather than using BDI as a proxy. BDI works as a directional indicator. TCE assessments by route are what you need when fixing an actual vessel.
What Subindex Divergence Tells You
The most commercially useful BDI reading is not the headline number. It is the spread between subindices.
Scenario | BCI | BPI | BSI | Signal |
China infrastructure cycle | Rising sharply | Flat or slightly up | Moderate | Steel mill iron ore restocking, Capesize demand surge |
Grain season spike | Slightly up | Rising sharply | Moderate | US Gulf or Black Sea grain exports driving Panamax demand |
Broad macro demand shift | All rising | All rising | All rising | Global trade acceleration, or fleet supply shock (port congestion) |
Post-cycle correction | Falling | Falling | Stable | Capesize fleet surplus after a high-ordering period |
Structural oversupply | Flat or negative | Low | Low | Too many vessels relative to cargo (2015-2016 pattern) |
When I see BCI rising while BPI is flat, I look at what is happening in Chinese steel production data before drawing any broader economic conclusion from BDI. The headline number is a blend. The subindices tell the story behind it.
BDI as a Leading Economic Indicator: How to Use It and Where It Fails
Where BDI Works
BDI has historically led global economic turning points by six to nine months. The index began declining in early 2007, approximately nine months before the 2008 recession was formally declared. It started recovering in late 2008 before GDP figures showed improvement. The mechanism is simple: raw materials must be ordered and shipped before industrial production can begin. Freight demand is a genuine forward indicator of factory output.
As the economist Howard Simons noted: “People don’t book freighters unless they have cargo to move.” There is no speculation embedded in a BDI reading. When BDI rises, cargo is physically moving.
Where BDI Fails or Misleads
BDI has real limitations that most articles gloss over.
It does not capture the services economy. Services now account for more than 60% of global GDP. BDI reflects only the physical movement of raw materials and says nothing about software, finance, healthcare, tourism, or trade in finished consumer goods.
It is not a proxy for container trade. Consumer goods move in containers, which have their own indices. A BDI decline does not necessarily mean consumer demand has fallen. It may mean industrial demand has softened while retail trade continues.
Capesize weighting creates China-specific sensitivity. Since the 2018 reweighting, BDI carries a 40% Capesize bias. When BCI spikes due to port congestion at Qingdao or a scrapping wave in the Capesize fleet, BDI moves without any corresponding shift in global trade volumes.
Peter Sand, Chief Shipping Analyst at BIMCO, has argued that BDI is now weighted toward larger sectors specifically to increase derivative-trading volatility, which reduces its utility as a pure economic signal. His alternative: tracking individual Time Charter Equivalent (TCE) estimates by vessel type, which can be compared directly to operating costs and give a clearer picture of whether owners are profitable.
Both uses have their place. BDI is a fast, freely available directional signal. TCE by vessel class is what a commercial professional needs to make an actual decision.
BDI and Freight Forward Agreements: The Settlement Connection
This section does not appear in any general BDI article. It is the commercially most important relationship for anyone working in shipping markets.
What Is a Freight Forward Agreement
A Freight Forward Agreement (FFA) is a financial derivative contract between two parties, typically a shipowner and a charterer or two trading desks, to fix a freight rate for a defined future period on a defined route. Settlement is in cash against the Baltic Exchange index for that route at the contract’s expiry date. No physical cargo changes hands.
A shipowner expecting BCI to fall might sell a BCI FFA contract to lock in today’s rate on future cargo. A charterer expecting BCI to rise might buy a BCI FFA to cap their future freight cost. The two positions net off, and the Baltic Exchange assessment on the settlement date determines who pays whom.
How Baltic Exchange Indices Govern FFA Settlement
The BCI, BPI, and BSI route assessments are the settlement benchmarks for FFA contracts. When an FFA on the C10 Pacific Capesize round voyage route expires, it settles at the average of the daily BCI C10 assessments during the contract month. Every digit in that panellist submission, every outlier call by the Baltic Exchange team, and every methodological decision about route weighting has a direct financial consequence.
This is why Baltic Exchange governance is not a formality. The organization has full audit processes, independent oversight, an ESG disclosure framework, and a specific governance structure for benchmark administration precisely because the numbers it publishes settle real financial contracts. LCH (London Clearing House) clears most FFA contracts, acting as central counterparty to reduce credit risk between the buyer and seller of each contract.
What FFA Pricing Tells You About Market Expectations
FFA forward curves for BCI, BPI, and BSI routes function as a forward market for freight rates, directly analogous to a commodity futures curve for crude oil or copper. When FFA forward rates are significantly above current BDI, the market is pricing in an expectation of rising freight rates. When forward contracts trade at a steep discount to current spot, the market is anticipating oversupply or demand weakness.
Professionals who track BDI alongside FFA forward curves get a far more complete market picture than BDI alone provides. The spot BDI tells you where the market is today. The FFA curve tells you where experienced market participants think it is heading.
BDI vs Other Shipping Indices: Tanker, Container, and Beyond
BDI covers only dry bulk. The Baltic Exchange and other organizations publish separate indices for other cargo types.
Index | Publisher | Covers | Volatility vs BDI |
BDI (Baltic Dry Index) | Baltic Exchange | Dry bulk: Capesize, Panamax, Supramax | Benchmark |
BDTI (Baltic Dirty Tanker Index) | Baltic Exchange | Crude oil tankers: VLCC, Suezmax, Aframax | Lower |
BCTI (Baltic Clean Tanker Index) | Baltic Exchange | Product tankers: LR1, LR2, MR | Lower |
FBX (Freightos Baltic Index) | Freightos / Baltic Exchange | Global container spot rates | High post-2020 |
SCFI (Shanghai Containerized Freight Index) | SSE | China-origin container exports | Moderate |
HARPEX | Harper Petersen | Container vessel charter rates | Lower, more seasonal |
Why BDI Is More Volatile Than Tanker Indices
Tanker vessels can load and unload in 24 to 48 hours. Bulk carriers take one to three weeks to load or unload cargo, depending on port equipment and berth availability. That difference in turnaround time makes tanker supply more flexible in response to demand shifts.
OPEC actively manages oil production to avoid large supply-demand imbalances, which keeps tanker demand steadier than dry bulk demand. Dry bulk demand ties directly to industrial output cycles and infrastructure investment, which are far more volatile than energy consumption.
Tankers also have more route substitution flexibility. A VLCC can shift between crude oil load ports relatively easily. A Capesize vessel is effectively locked into a small number of high-volume corridors by its draft and beam dimensions.
These structural differences explain why BDI swings from 290 to 11,793 while tanker indices move in much narrower ranges over the same period.
BDI and Vessel Asset Values: The Connection Most Articles Skip
No competitor article in the current SERP addresses this relationship. It is the most relevant dimension of BDI for anyone involved in maritime asset finance or vessel ownership.
How BDI Cycles Historically Tracked Secondhand Vessel Prices
When BDI ran above 10,000 in May 2008, Capesize secondhand vessel values peaked alongside it. A five-year-old Capesize vessel was worth $150 million or more during that period. When BDI crashed to 663 by December 2008, vessel values followed with a lag of two to four quarters. By 2009, the same vessel was worth less than $50 million.
The relationship is not mechanically precise. Vessel values lag BDI because buyers and sellers need time to adjust their expectations, and financing conditions change independently. But BDI trend direction over multiple quarters is a reliable leading signal for vessel earnings capacity, and vessel earnings capacity is the primary input in any secondhand vessel valuation.
When BDI hit its all-time low of 290 in February 2016, owners were scrapping Capesize vessels at scrap steel value, sometimes below book value, because the cost of keeping them in service exceeded the revenue they could generate. When BDI recovered to 5,650 in 2021, secondhand Capesize values exceeded $60 million for five-year-old vessels.
Charter Rate Embedded in Vessel Earnings
A vessel’s income-generating capacity in any period is determined primarily by prevailing time charter rates. Time charter rates for Capesize, Panamax, and Supramax vessels are the exact inputs that become BCI, BPI, and BSI assessments. When BDI trends upward over a sustained period, charter rates across all three vessel classes are rising, and the earnings capability of every dry bulk asset is improving.
This is not an investment claim. It is a mechanical relationship. BDI does not tell you what a vessel is worth. It tells you what the earning environment for dry bulk assets looks like today. Understanding where BDI sits in its historical range, which subindex is driving the move, and what FFA forward curves imply about market expectations gives a maritime asset professional far more context than looking at a vessel’s book value in isolation.

Historical BDI Milestones: Key Moves and What Drove Them
Period | BDI Level | Driver | Commercial Consequence |
2003 to 2007 | 1,000 rising to 11,793 | China infrastructure boom, Olympic preparation, commodity supercycle | Capesize values tripled; a major newbuild ordering wave was triggered |
May 2008 | 11,793 (record high) | Peak China demand + fleet constraint | Capesize TCE rates above $200,000/day on some routes |
December 2008 | 663 (94% fall in 7 months) | Global financial crisis, credit freeze, commodity demand collapse | Vessels approaching operating cost floor; several major owners defaulted |
2011 | 4,661 then 1,043 | Recovery interrupted by Queensland flooding and newbuild deliveries | Owners caught between rising vessel supply and recovering demand |
February 2016 | 290 (all-time low) | Structural oversupply from post-2008 ordering wave; China property slowdown | Capesize scrapping wave; HSH Nordbank crisis deepened |
2021 | 5,650 (post-COVID peak) | Simultaneous demand recovery + port congestion reducing effective fleet supply | 5-year-old Capesize values exceeded $60 million |
2022 to 2024 | 1,200 to 2,500 (normalization) | Fleet delivery catch-up; China property sector slowdown reducing steel demand | TCE rates normalizing; vessel ordering becoming selective by segment |
2025 | 700 to 2,270 (trough then recovery) | Early-year China property sector drag compressed Capesize demand; H2 recovery as Brazilian iron ore exports surged and China grain imports increased | Capesize asset values compressed in H1; secondhand market recovery through late 2025 |
Jan to Jun 2026 | 1,995 to 3,227 (multi-year high) | Brazilian iron ore corridor surge; tightening effective Capesize supply as limited newbuilds arrived | Secondhand Capesize values recovering toward mid-cycle levels |
The 2016 episode is worth holding as a reference point. The all-time low of 290 was not a brief shock like 2008. It was the outcome of years of cumulative ordering that added capacity far faster than demand could absorb. Owners who had ordered vessels at 2007 or 2008 values on the assumption that BDI would remain elevated found themselves servicing debt on assets generating income below operating costs. That is the risk that structural oversupply creates, and it recurs in shipping markets with regularity.

Frequently Asked Questions
What is the Baltic Dry Index?
The Baltic Dry Index (BDI) is a daily shipping freight cost index published by the Baltic Exchange in London. It measures the cost of transporting dry bulk commodities across 20 ocean routes, using time charter rate assessments submitted by an international panel of member shipbrokers. BDI is a weighted composite of three vessel-class subindices: Baltic Capesize Index (40%), Baltic Panamax Index (30%), and Baltic Supramax Index (30%). It has been published in its current form since November 1999.
How is the BDI calculated?
Each working day, approved Baltic Exchange panellist firms submit their assessment of current hire rates for 20 designated routes across three vessel classes. The Baltic Exchange validates submissions, removes outliers, and averages the valid submissions per route. Route averages are aggregated into BCI, BPI, and BSI subindices, then combined at 40/30/30 to produce BDI. The index is published daily around midday London time.
What does a rising BDI mean?
A rising BDI means demand for dry bulk shipping capacity is increasing relative to vessel supply, and charter rates are rising. In most cases, this reflects growing demand for raw materials such as iron ore, coal, or grain. Whether it indicates a China iron ore cycle, a seasonal grain movement, or broader macro demand growth depends on which subindex is leading the move.
What does a falling BDI mean?
A falling BDI means charter rates are declining because vessel supply is outpacing cargo demand. This can reflect economic slowdown, reduced demand from major commodity importers, or a cyclical oversupply of vessels following a high-ordering period. A sustained BDI decline pushes vessel earnings toward their operating cost floor. The 2016 all-time low of 290 is the most extreme recent example of what structural oversupply looks like in BDI terms.
What is the difference between BDI, BCI, BPI, and BSI?
BDI is the composite index. BCI (Baltic Capesize Index), BPI (Baltic Panamax Index), and BSI (Baltic Supramax Index) are the three vessel-class subindices that combine to produce it. BCI tracks the largest vessels carrying iron ore and coal on major bulk corridors and is weighted at 40% of BDI. BPI tracks medium-size vessels on grain and Atlantic round voyages (30%). BSI tracks smaller, more versatile vessels on minor bulk and shorter routes (30%).
What is a Freight Forward Agreement and how does it relate to BDI?
A Freight Forward Agreement (FFA) is a financial contract between two parties to fix a freight rate for a future period on a defined route, settling in cash against the relevant Baltic Exchange route assessment at expiry. No physical cargo changes hands. BCI, BPI, and BSI route assessments are the settlement benchmarks for FFA contracts. This makes Baltic Exchange panellist accuracy financially consequential well beyond the shipping market itself.
Why is BDI considered a leading economic indicator?
BDI leads economic activity because raw materials must be ordered and shipped before industrial production can begin. When BDI rises, physical cargo orders are being placed: iron ore for steel production, coal for power generation, grain for food processing. This real-economy demand signal precedes the factory output and GDP data that economists report months later. The index dropped in early 2007, nine months before the 2008 recession was declared, and began recovering before GDP figures showed improvement.
What are BDI’s main limitations?
BDI does not capture services, which represent more than 60% of global GDP. It does not cover containerized consumer goods. It is heavily weighted toward Capesize vessels, making it sensitive to Chinese steel production rather than global trade broadly. It can be distorted by port congestion or fleet supply changes unrelated to underlying cargo demand. Peter Sand of BIMCO has argued that post-2018 Capesize weighting was increased partly to generate derivative-trading volatility, which reduces BDI’s utility as a pure economic signal.
What was the highest BDI ever recorded?
The highest BDI on record was 11,793, reached on 20 May 2008. It was driven by peak demand from China’s pre-Olympic infrastructure buildout, a commodity supercycle, and a fleet that had not yet received the wave of newbuildings ordered in 2006 and 2007. The index fell 94% from that peak to 663 by December 2008, one of the fastest and largest collapses of any major market index in the post-war era.
What was the lowest BDI ever recorded?
The lowest BDI on record was 290, reached in February 2016. This reflected years of cumulative fleet over-ordering following the 2008 peak, combined with a slowdown in Chinese steel and infrastructure demand. Many Capesize owners were scrapping vessels at below book value because operating them generated losses. The 2016 low was not a demand shock like 2008; it was the outcome of sustained structural oversupply in the bulk carrier fleet.
How do I track the BDI daily?
BDI is published daily by the Baltic Exchange and accessible on subscription directly from balticexchange.com. It is also available through Bloomberg and Reuters terminals. Free daily readings can be tracked through financial data sites including Investing.com, TradingEconomics, and Barchart. The Baltic Exchange also publishes a weekly market roundup available without full subscription.
How is BDI different from container shipping indices?
BDI covers only dry bulk vessels carrying loose, unpackaged commodities such as iron ore, coal, and grain. Container shipping has separate indices: the Freightos Baltic Index (FBX) covers global container spot rates, and the Shanghai Containerized Freight Index (SCFI) covers China-origin container exports. These indices track the cost of shipping packaged goods in standard containers and are driven by consumer goods demand cycles rather than industrial raw material flows.

Ton-mile demand: A measure of shipping demand combining cargo volume in metric tons with the distance carried in nautical miles.
Scrapping / ship recycling: The dismantling of a vessel at end of life for scrap steel value. Scrapping waves typically occur during prolonged BDI downturns when vessel earnings approach operating costs.
Newbuild orderbook: The total fleet of vessels currently contracted at shipyards for future delivery. A large orderbook indicates future vessel supply growth, which tends to suppress charter rates over the delivery period.
Supply inelasticity: The characteristic of shipping supply that prevents it from responding quickly to demand changes. Building a new vessel takes two to three years, so short-term demand increases drive disproportionate rate spikes.
Iron ore corridor: The shipping routes between major iron ore export origins (Australia, Brazil) and major import destinations (China, Japan, South Korea). The primary driver of Capesize vessel demand and BCI.
Grain season: The seasonal peak in dry bulk shipping demand from agricultural export cycles, primarily US Gulf, Black Sea, and South American origins. Typically runs September to February. The main seasonal driver of BPI.
Baltic Freight Index (BFI): The predecessor to BDI, first published in January 1985. Transitioned to the current Baltic Dry Index format in November 1999.
