Freight rally defies weak commodity pricing
The Baltic Dry Index (BDI) is outperforming its recent history. As of mid-May 2026, the BDI is tracking more than 70% above its start-of-year level. This is the second strongest year-to-date performance at this point since 2015, exceeded only by the extraordinary 2021 pandemic surge, which peaked at over 300% above its January level by October of that year. The signal from the BDI is clear – dry bulk freight markets are tightening, mainly due to structural factors, with the Middle East conflict having an indirect role.
Freight is firm because cargo is moving, tonne-miles are expanding and effective vessel availability is tight, even though bulk commodity prices are not signalling a synchronised upcycle. The current rally is finding support on broad-based improvements in utilisation under constrained supply. Capesize rates have risen sharply above both Panamax and Supramax, indicating that the rally is being led by the large bulk trades rather than by grains or smaller minor bulks. That points directly to the commodities which dominate long-haul dry bulk demand into Asia, its main market: iron ore, coal and increasingly bauxite.
Major bulks are providing the floor, not the upside
Iron ore remains the anchor of the freight market, dominating bulk commodity trade. Exports of iron ore into Asia (~85% of world iron ore exports) have stayed broadly stable into 2026, generally running at around 150–200 Mt per month, with Australia and Brazil – which had a strong 2025 – indicating no step-change in underlying seaborne demand. At the same time, the iron ore price (62% Fe, CFR, China) is hovering around $110 /t, edging modestly higher from recent lows. This is a cost-push rather than demand driven increase, reflecting the current rising freight rates and delivered costs rather than a tightening physical market.
Stable iron ore volumes provide a base level of utilisation for Capesize vessels but are not generating incremental tonne mile demand, so the recent strength in freight rates cannot be attributed to iron ore. Instead, higher freight rates reflect tightening conditions elsewhere in the bulk system.
Thermal coal exports into Asia (~60% of world thermal coal exports) have been falling at the start of 2026, consistent with the end of the peak heating season in the Northern Hemisphere, broadly oscillating around the mid 40 Mt/month level, with Indonesia and Australia maintaining consistent supply shares and no clear step up in aggregate volumes. As with iron ore, the thermal coal price (FOB Newcastle, 6,000 kcal/kg) shows a modest uptick visible into 2026.
This marginal recent increase in price is also consistent with slightly elevated freight costs feeding through to delivered coal prices, supported for now by a modest shift from gas-to-coal demand amid higher natural gas prices. As such, coal is viewed as providing steady, background utilisation for Capesize and Panamax fleets, rather than acting as a catalyst for tightening.
Bauxite is driving higher demand in tonne-mile terms
The clearest incremental change in the current market is the aluminium value chain, which is becoming a much more important marginal driver of freight than it used to be. Bauxite exports into Asia (~95% of world bauxite exports) have risen strongly since 2021, doubling from around 10 Mt per month in early 2021 to around 20 Mt per month by the latest point in 2026, with a notable rise in 2026 Q1.
Guinea is at the centre of that growth, followed by Australia. The significance of Guinea as a bauxite exporter is its distance. Guinea-to-China is one of the longest dry bulk routes in the market. That means a tonne of bauxite from Guinea absorbs vessel capacity, usually from the Capesize segment, for much longer than a tonne of coal from Indonesia or a tonne of iron ore from Australia.
The commodity price signal is also important here. The CRU Alumina Price Index (Australia, FOB) was around $300 /t in early 2021, spiked to around $750 /t in late 2024 to early 2025, before retreating sharply. As of mid-2026, it is back around $300 /t. That tells us that while alumina prices have normalised, the physical bauxite trade has remained high. Freight is therefore being supported by structural trade expansion rather than by temporarily high margins for refining bauxite.
This is now visible in the tonne-mile data, which multiplies the trade volume data by port-to-port nautical miles. In 2026 Q1, bauxite exports into Asia generated a total of 365.7 bn tonne-nm, with Guinea alone accounting for 311.83 bn tonne-nm. Applying a similar calculation with the trade figures for coal above, bauxite's 365.7 bn tonne-nm is already around 73% of thermal coal's 500.5 bn tonne-nm. In tonnage terms, coal is still much larger. In tonne-mile terms, bauxite is much closer. This means the aluminium raw materials chain is no longer a peripheral contributor to dry bulk demand. It is becoming one of the main marginal users of large-vessel capacity into Asia.
The aluminium value chain is becoming the swing factor
The aluminium value chain has not overtaken iron ore or coal as the core driver of freight. Iron ore still sets the base load for Capesize demand because of its sheer scale and regularity. Coal still matters because of the breadth of its trade and the large number of routes and cargo stems it supports. However, bauxite is increasingly part of the explanation for why freight rates can spike and remain high even when iron ore and coal prices themselves are not signalling exceptional tightness. The aluminium chain is not the centre of the freight market, but it is becoming one of its most important swing factors.
Higher bauxite trade reflects a broader reorganisation of the aluminium value chain, especially the rising role of Guinea as a supplier of feedstock into Chinese alumina refining. That means the freight effect is structural rather than cyclical. As more of the aluminium raw material system is sourced from long-haul Atlantic-to-Asia routes, vessel demand rises not only with more cargo, but with longer cargo duration. That is more powerful for freight than a simple volume increase on shorter routes.
The Capesize market is reflecting exactly that. The strongest moves in dry bulk today are not in Supramax, where smaller minor bulks dominate, but in Capesize, where iron ore and now increasingly bauxite matter most. Panamax is rising as well, driven by marginally higher coal exports and bauxite shippers using the segment for smaller cargo parcels. This is consistent with a market being tightened by long-haul bulk raw materials rather than by a broad surge across all trade categories.
Tight vessel supply is amplifying the freight response
On the supply side, the near-term backdrop remains supportive of higher freight rates. Net fleet supply is moderating rather than expanding aggressively, with sustained reductions in the Capesize segment, even though its orderbook as a share of fleet is now rising. The orderbook of new ships is becoming stronger across all segments and for Capesize it is now turning up sharply, rising from 5% two years ago to 15% in 2026 Q1. That is a medium-term warning that supply will eventually respond, but those ships are not yet available. For now, the market remains exposed to high utilisation and sudden spikes in spot rates whenever cargo demand strengthens further.
In that environment, the expansion in bauxite trade is resulting in a tightening of effective vessel availability. With limited incremental fleet supply and only gradual orderbook replenishment, the system is leading to an outsized, non-linear response in freight rates. This dynamic explains why the Capesize volatility, which spills over into the Panamax segment as it absorbs demand, reflect a cycle driven by physical flows and constrained supply rather than commodity price signals.
Bunker fuel prices have risen more than 50% since the start of the Middle East conflict and are reinforcing that tightness. More expensive bunker fuel raises voyage costs directly, so the market-clearing freight rate must also rise, but they also affect supply indirectly. When bunker prices rise, vessel operators have a greater incentive to steam slowly in order to reduce fuel consumption. Slower steaming lengthens voyages and reduces the effective availability of the fleet. No ships disappear physically, but fewer voyage cycles can be completed over a given period. That tightens the market in operational terms and magnifies the impact of any increase in tonne-mile demand.
Guinea’s policy risk can amplify the freight response
Overall, the recent dry bulk freight rally reflects more than iron ore strength. While iron ore anchors demand and coal remains essential, the aluminium raw materials chain has emerged as a key marginal driver. When bauxite trade volumes surge together with any other major dry bulk – as occurred in 2025 Q4 with stronger Brazilian iron ore exports – freight rates typically spike sharply. For now, the more long-haul bauxite into Asia rises, a shift from-gas-to-coal exports consolidates, and the longer bunker costs stay elevated, the more durable the current freight support is likely to be.
By themselves, China’s bauxite imports from Guinea reflect a structural shift tied to alumina refinery expansion, including in Guangxi, and to resource security, rather than the cyclical and seasonal demand seen in iron ore (steel output) or coal (electricity generation and heating). Unlike those well-defined cycles, Guinea–China bauxite flows tend to appear more strongly and are less sensitive to short term price signals, creating a steady increase in long haul tonne mile demand. This makes freight outcomes more prone to sudden tightening, as rates become increasingly less driven by clear commodity cycles, amplifying volatility when supply constraints or routing inefficiencies emerge.
Potential policy risk in Guinea introduces an additional layer of upside and volatility, as any bauxite export restrictions or bans, such as those previously implemented by Indonesia, are likely to prompt front loading of imports by Chinese buyers. This behaviour would temporarily accelerate bauxite shipments, further boosting tonne mile demand and tightening vessel availability, thereby amplifying short term freight strength even in the absence of underlying price support. This dynamic has been a key factor behind the recent rally.
