What is the Baltic freight market?
The Baltic freight market is the body of published benchmarks, route assessments and indices that describe the cost of moving dry bulk cargo by sea, anchored by the Baltic Exchange in London and headlined by the Baltic Dry Index. It is the reference point the whole dry bulk trade uses to talk about whether freight is cheap or expensive on a given day.
This page is an evergreen explainer of how that market is structured. It does not publish current freight levels. The aim is to make the machinery legible: what the Baltic Exchange actually is, how the Baltic Dry Index and its component indices are built from broker-submitted route assessments, what the index signals about supply and demand, and how charterers and owners read it. For live numbers, this page points to the rate tools and the market blog rather than quoting figures that would go stale.
The reason the Baltic market matters is that dry bulk freight has no single exchange-traded price the way a commodity does. A bulk fixture is privately negotiated between an owner and a charterer for a specific cargo, lane and laycan. The Baltic Exchange exists to turn that scattered, private activity into a transparent daily benchmark, so that a desk in Singapore and a desk in Geneva can argue about the same number.
What the Baltic Exchange is
The Baltic Exchange is a London-based membership organisation, founded in the eighteenth century and today owned by Singapore Exchange, whose core function in the dry bulk world is to publish independent daily freight benchmarks. It is not a place where ships or cargoes are bought; it is the institution that collects, averages and publishes freight assessments.
The mechanism is a panel system. The Exchange maintains panels of independent shipbroking firms, the panellists, who each submit a daily assessment of where they judge the freight rate to be for a defined set of standardised routes. These are professional judgements of the going market rate, informed by the fixtures and negotiations each broker sees, not a feed of executed transactions. The Exchange aggregates the panellist submissions, applies its published rules to discard outliers, and produces the assessed figure for each route. Those route figures are the raw material for every Baltic index.
Two features make the assessments useful. First, the routes are standardised: each is defined against a notional vessel of a given size carrying a stated cargo between named load and discharge regions, so the figure is comparable from one day to the next. Second, the panel is independent and the methodology is published, which is what gives the numbers enough credibility to settle financial contracts. Forward freight agreements, the derivatives that owners and charterers use to hedge freight exposure, settle against Baltic route assessments precisely because the process is rules-based and transparent.
The Baltic Dry Index and its component indices
The Baltic Dry Index is the headline composite, but it sits on top of a set of class-specific indices that are more useful for any desk fixing a particular size of ship. The table below sets out the main dry bulk indices and what each one tracks.
| Index | Vessel class | What it tracks |
|---|---|---|
| BDI (Baltic Dry Index) | Composite of Capesize, Panamax, Supramax | The headline barometer of dry bulk freight, built as a weighted blend of the three class indices below |
| BCI (Baltic Capesize Index) | Capesize (~150,000 to 210,000 dwt) | Freight on the largest dry bulk ships, dominated by iron ore and coal on long ocean headhauls |
| BPI (Baltic Panamax Index) | Panamax / Kamsarmax (~65,000 to 90,000 dwt) | Freight on the mid-size geared and gearless fleet carrying coal, grain and minerals |
| BSI (Baltic Supramax Index) | Supramax / Ultramax (~52,000 to 66,000 dwt) | Freight on geared mid-size ships running flexible multi-cargo and minor-bulk trades |
| BHSI (Baltic Handysize Index) | Handysize (~28,000 to 40,000 dwt) | Freight on the smallest ocean-going bulkers; published by the Exchange but not part of the headline BDI composite |
The headline BDI is the number that reaches the financial press, but it is the class indices that a chartering desk actually watches. An owner with a Capesize open in the Atlantic cares about the Capesize routes in the BCI, not the composite. A grain trader fixing a Panamax lift watches the BPI. The composite BDI is most useful as a single market mood reading and as the long-run series that analysts use to compare freight cycles across years.
A point that trips up newcomers: the Handysize index (BHSI) is published by the Exchange and is a real benchmark for the Handysize class, but it does not feed the headline BDI composite, which is built from the Capesize, Panamax and Supramax indices. The composite weighting is set and reviewed by the Exchange and has changed over the years, so the BDI is best read as a managed blend rather than a fixed formula.
How the index is constructed from route assessments
The construction runs bottom-up, from individual route assessments to the headline number. Each step is governed by the Exchange’s published methodology.
- Route assessments. For each vessel class, the Exchange defines a basket of standardised routes, each specified against a notional vessel and a stated cargo and lane. Every panellist broker submits a daily figure for each route. The Exchange averages the panellist submissions, after applying its rules to handle outliers, to produce the assessed rate for that route.
- Time-charter equivalent. The headline indices are expressed on a time-charter-equivalent basis, in US dollars per day, so that voyage routes and period routes can be compared on the same footing. Converting a voyage route into a per-day equivalent is the same calculation a desk runs when it works up a freight rate for a fixture.
- Class index. The per-route figures for a vessel class are combined into that class index. The BCI, BPI, BSI and BHSI are each the aggregate of their own route baskets.
- Headline composite. The Capesize, Panamax and Supramax class indices are weighted together to produce the headline BDI. The Exchange publishes the weighting and reviews it periodically.
The route definitions, vessel descriptions and weightings are not arbitrary. They are published, consulted on with the panel and the wider market, and revised when the trade changes, for example when a new vessel size becomes the workhorse on a lane. Treat the specific route baskets and weightings as values to verify against the Exchange’s current methodology rather than as fixed constants, since they are reviewed over time.
What the BDI signals and how the market reads it
The Baltic Dry Index is read as a barometer of dry bulk demand and freight rates. Because the supply of ships is close to fixed in the short run, a new bulker takes years from order to delivery, the index moves mostly on the demand side. When iron ore, coal and grain cargoes are plentiful relative to available tonnage, assessed rates rise and the BDI climbs. When cargo thins out, ships compete for fewer stems and the index falls. This near-fixed supply is why the BDI is famously volatile and why it can double or halve over a few months.
Read with care, the index carries information beyond freight itself. Because Capesize demand is dominated by iron ore and coal, a strong BCI is often taken as a signal of steel-making and industrial activity, particularly in China. Because Panamax and Supramax demand leans more on coal, grain and minor bulks, the spread between the class indices tells a desk where the strength sits. A market where the BCI is racing ahead of the BPI is a different market from one where the smaller classes lead, and that divergence is part of what an experienced reader extracts from the indices.
The important caution is that the BDI is a benchmark, not a bookable price. It tells you where the assessed routes sit; it does not tell you what a specific cargo on a specific lane with a specific laycan will fix at. A real fixture reflects the exact ship, the ballast leg, port costs, bunker prices and the negotiating positions of the two parties. The index is the starting reference, and the desk works from there.
How charterers and owners use the indices
Both sides of the market use the Baltic numbers as a common reference, but they use them differently.
A charterer uses the relevant class index as a sanity check on quotes. If brokers are offering tonnage well above the assessed route level, that is a flag to push back or wait. The charterer also uses the index to decide between instruments: when the index is high and volatile, a voyage charter avoids locking in an expensive period rate, whereas a settled, low market can make a time charter attractive. Either way the index informs the decision rather than dictating the price.
An owner uses the index to judge whether to fix now or hold out for a firmer market, and to benchmark the time-charter equivalent a given voyage would earn against the assessed route. Owners and charterers who want to fix or hedge their exposure beyond the next fixture trade forward freight agreements that settle against Baltic route assessments, which is only possible because the assessment process is rules-based and independent.
For either side, the practical workflow is the same: read the index for direction and level, then run a voyage estimate or freight rate calculation for the actual cargo to turn the benchmark into a number you can negotiate against.
Where to find current numbers
This page deliberately does not quote current index levels or freight rates, because they would be stale within days. For live and worked numbers, use the tools and the market commentary below.
- Indicative rates for your cargo. The rate calculator turns a distance and a daily hire figure into an indicative voyage cost for a specific lane, which is how you convert an index reading into a usable estimate.
- Current market commentary. The blog post bulk shipping rates 2026 tracks where the market sits and how the indices have moved, with figures that are kept current.
- How a freight rate is built. The freight rate page explains the components that turn an index assessment into a quoted rate, including bunker, port costs and the time-charter-equivalent conversion.
For the authoritative index figures themselves, the Baltic Exchange is the source of record. This page is the conceptual map, not the live data board.
Scope and what this page does not cover
This page explains the Baltic freight market as a structure: the Baltic Exchange, the Baltic Dry Index and its component class indices, how the indices are assessed and constructed, and how the market reads and uses them. It does not publish current index levels, forecast where freight is heading, quote a rate for any specific lane, or advise on a particular fixture. The route baskets, vessel descriptions and composite weightings are reviewed by the Exchange over time and should be verified against its current published methodology. For live numbers, use the rate calculator and the bulk shipping rates 2026 blog post; for commercial decisions, work with a desk broker against current Baltic Exchange data.
