Catch Volumes & Seasonality

Tuna catches are seasonal. In 2024, reduced catches in WCP due to El Niño conditions (poor free-school fishing) kept raw material prices firm. The opening of FAD fishing in October didn’t dramatically flood the market, so raw tuna remained in demand. If a season yields poor fishing (e.g., bad weather, El Niño causing tuna to disperse), supply tightens and prices rise. This happened in late 2023 in the WCPO where catches were “anything but stable” – skipjack remained low, supporting price. Conversely, when there’s a bumper fishing quarter, prices ease. For yellowfin specifically, any shortfall in one ocean (say IOTC cutbacks) can be partly offset by others – but regional deficits do push price. Seasonality also affects quality: fish caught in certain seasons may have different fat content or meat quality, which can indirectly influence price if buyers prefer one season’s fish over another’s.

Fishing Effort & Costs

A major underlying cost is fuel. Tuna fleets are fuel-intensive (purse seiners burn a lot searching for fish). High fuel prices (like in 2022 when oil spiked) can lead fleets to curtail effort or demand higher prices to cover costs. In 2023 and 2024, fuel costs moderated somewhat, which helped keep tuna prices from exploding even when catches were down. Another factor is fleet behavior: RFMOs limiting FADs or setting quotas (like ICCAT reduced Atlantic FAD closure from 72 to 45 days in 2022, which actually could increase catches, lowering price). If Indian Ocean enforce catch limits strictly, less fish on market could push price up; as of 2024, compliance was mixed, but if IOTC gets serious, it’s bullish for prices.

Demand Trends in End Markets

Consumer demand for tuna products directly affects how much raw material buyers will seek. During 2020–2021, canned tuna demand spiked (pandemic stockpiling), raising raw tuna prices. In 2023–2024, demand for canned tuna in the West cooled off (people had pantry fatigue), which led to weaker prices especially for skipjack. At the same time, demand for fresh/frozen tuna in foodservice rebounded as restaurants reopened. In early 2024, U.S. fresh tuna imports were up (particularly high-value bluefin, as Japanese cuisine restaurants thrived), and while overall non-canned tuna imports to the U.S. fell in 2023 due to a drop in frozen fillets, by late 2024 they were rising again. Japan’s market also influences price: Japan is the top sashimi tuna consumer; if their imports of frozen sashimi tuna drop, then suppliers may pivot to other markets or accept lower prices. Conversely, if Japan’s economy is strong and tourism increases (boosting sushi consumption), they’ll absorb more high-grade tuna, tightening supply globally and raising prices for #1 grade.

Exchange Rates and Trade Policies

Tuna trade is global and primarily USD-denominated. A strong dollar can make tuna more expensive in local currency for import-dependent countries, potentially dampening demand. Meanwhile, tariffs or trade agreements can shift sourcing. For example, the EU’s free trade agreements with exporters (like Ecuador, Vietnam’s FTA with EU) can reduce or eliminate import duties, making those sources more competitive on price. If a country loses a trade privilege (say, if Thailand faced higher tariffs in EU for processed tuna), their prices effectively go up relative to others.

Competitor Species

Yellowfin doesn’t exist in a vacuum. It competes with bigeye tuna in the sashimi market (bigeye is often slightly higher value for sashimi due to fattier flesh) and with albacore in some loin markets (albacore loins for canning white tuna). If bigeye stocks or quotas cause bigeye price to soar, some sashimi buyers might substitute high-quality yellowfin, thus lifting yellowfin prices. Conversely, if bigeye is plentiful and cheaper, it can cap yellowfin sashimi prices. Similarly, in the canned tuna arena, skipjack price heavily influences yellowfin pricing.

Logistics and Cold Chain Costs

The cost of freight and container availability also feed into final prices. The pandemic years saw extremely high container shipping costs, which added several cents per pound to tuna costs for importers. By 2023, freight rates normalized or even overcorrected to cheaper levels, slightly easing CIF (Cost, Insurance, Freight) prices of tuna deliveries.

Inflation in Production

Processing costs have risen in many countries. Labor wages in Vietnam, Thailand, etc., have been climbing. Energy costs for running freezers have increased with global energy prices. Packaging materials (vacuum bags, cartons) also saw inflation. All these push up the conversion cost from whole fish to finished product.
