Ocean freight rates for shipping grain from the United States surged significantly in the third quarter of 2026, with rates from the U.S. Gulf to Japan jumping 34% compared to the same period last year, driven by sustained demand for bulk commodities, rising bunker fuel costs, and Panama Canal restrictions that forced vessels to take longer routes.
- U.S. Gulf-to-Japan rates averaged $72.76 per metric ton in Q3 2026, up 34% year-over-year and 28% above the four-year average.
- Bunker fuel costs for very low sulfur fuel oil (VLSFO) reached $862.73 per metric ton in September, up 65% from September 2025.
- Panama Canal restrictions reduced transit slots and draft capacity, forcing vessels to reroute around Africa, adding ton-miles and increasing shipping costs.
- Strong grain demand from China and increased U.S. soybean purchases, combined with Argentina's record corn harvest, sustained upward pressure on rates.
- Mixed outlook ahead: Growing fleet capacity may moderate rates, but persistent bunker fuel costs, El Niño weather conditions, and continued harvest activity could push rates higher.
Ocean freight rates for shipping grain from the United States rose sharply in third quarter 2026, driven by sustained demand for bulk commodities and climbing bunker fuel costs, according to the U.S. Department of Agriculture’s Agricultural Marketing Service weekly Grain Transportation Report.
Rates from the U.S. Gulf to Japan averaged $72.76 per metric ton (mt) in third quarter 2026, up 5% from second quarter 2026, up 34% from third quarter 2025, and up 28% from the prior four-year average. From the Pacific Northwest (PNW) to Japan, rates averaged $36.67 per mt, up 1% quarter to quarter, up 26% year to year, and up 17% from the four-year average.
The spread between U.S. Gulf-to-Japan and PNW-to-Japan rates jumped 9% from quarter to quarter, 43% year to year, and 41% from the four-year average. Meanwhile, rates from the U.S. Gulf to Europe averaged $22.54 per mt, unchanged from the previous quarter but down 8% year to year and down 17% from the four-year average.
Monthly factors shape rate movements
Ocean freight rates showed varied patterns throughout the quarter as multiple factors influenced vessel demand and availability.
In July, rates fell slightly as China’s iron ore imports dropped 4% to 108.09 million metric tons (mmt) from 112.69 mmt in June. China’s finished steel exports also declined 1.99% to 10.12 mmt, reflecting a typical seasonal slowdown in steel production. Indonesia’s thermal coal shipments decreased from the previous year, directly affecting Panamax and Supramax vessel utilization across Asia, particularly on short-haul routes between Indonesia and China.
Weather events in China further weakened shipping demand. Heavy storms and Typhoon Maysak produced flooding and congestion at Chinese ports, disrupting operations and delaying customs clearance.
August brought a reversal as China’s iron ore imports defied analyst predictions, rising 0.4% to 108.54 mmt despite typhoon disruptions. Steel exports climbed 0.4% above July and 6.8% above the previous year to 10.16 mmt. Vessel activity received boosts from increased traffic out of Asia after storm disruptions subsided and strong grain shipments from the U.S. Gulf and East Coast South America, especially Argentina.
Following Argentina’s unprecedented harvest, that country’s corn exports surged in August. The Panama Canal Authority instituted draft restrictions and reduced transit slots, anticipating reduced rainfall through October. These actions translated to lighter cargo loads per shipment, higher costs for transit slots, and more vessels rerouting around the southern tip of Africa, adding ton-miles and pushing up rates.
September saw continued rate increases as demand for iron ore and coal held strong. In the Pacific, demand for Panamax vessels was driven by high coal demand from Australia and Indonesia as Middle East tensions tightened the energy market. Greater purchases of U.S. soybeans by China and rising grain demand from North Pacific and East Coast South America added upward pressure.
Although congestion eased at the Panama Canal, bookings remained scarce because of draft restrictions and transit slot reductions ahead of anticipated El Niño weather events. Higher long-haul demand for Capesize and Panamax vessels was driven by Chinese imports of Guinea bauxite amid low Chinese port stocks.
Bunker fuel costs climb sharply
Bunker fuel costs continued to rise throughout the quarter. The Global 20 ports average price per metric ton for very low sulfur fuel oil (VLSFO, IMO 2020 Grade 0.5%) reached $862.73 in September, up from $809.81 in August and $523.12 in September 2025, representing increases of 7% and 65%, respectively. Higher bunker fuel costs typically drive up vessel operating costs and raise ocean freight rates.
Market outlook shows mixed signals
For the week ending Oct. 8, the rate to ship 1 mt of grain from the U.S. Gulf to Japan was $76.25, 53% more than the first available rate at the beginning of the year and 36% more than the same week in 2025. The rate from the PNW to Japan was $37.50 per mt, 42% more than the first available rate at the beginning of the year and 28% more than the same 2025 period.
Several factors could moderate rates. The global dry bulk operating fleet capacity was estimated at 1,095.5 million deadweight tons (mdwt) in September, a 4% rise from 1,056.4 mdwt capacity in September 2025. The share of inactive vessels remained stable compared to September 2025. This growth in capacity could slow the rise in ocean rates or even push them down in the short run.
However, multiple factors may push rates up. Strong loading activity will likely continue, especially during harvest season. As of the week ending Oct. 8, a year-to-date weekly average of 29 oceangoing grain vessels had been loaded in the U.S. Gulf, and a year-to-date weekly average of 15 vessels had been either loaded or waiting to load in the PNW, compared to averages of 27 vessels and 13 vessels, respectively, during the same period in 2025.
If higher bunker prices persist, vessel operators may attempt to conserve fuel and reduce costs through “slow steaming,” lengthening transit times. The longer transit times would push up ocean freight rates by reducing available vessel capacity. If El Niño-related conditions further restrict Panama Canal transits and force more vessels to reroute around Africa, the available fleet’s ton-miles could continue to rise and further push up rates. This effect may be magnified if strong U.S. grain exports coincide with the transit restrictions.
