Soybean Price Volatility and Geopolitical Risk: How U.S.-China Trade Negotiations Could Reshape Global Markets

The soybean market has long been a barometer for U.S.-China trade tensions, and 2025 has proven no exception. With China's abrupt halt of U.S. soybean purchases and retaliatory tariffs pushing American farmers to the brink, the upcoming APEC summit in South Korea-scheduled for October 31 to November 1-has become a pivotal moment for global agricultural markets. Investors and analysts are now scrutinizing how the Trump-Xi meeting might recalibrate trade terms, tariffs, and demand dynamics, with soybean prices already surging to a month-high amid speculation, according to a Brookings analysis.

A Market in Crisis: The U.S. Soybean Dilemma

The U.S. soybean export crisis deepened in 2025 as China, once the largest buyer of American soybeans, redirected its imports to Brazil and Argentina. By October 2025, South American suppliers accounted for 95% of China's soybean demand, Reuters reported, a shift driven by China's 34% retaliatory tariffs on U.S. soybeans and the Trump administration's 125% tariffs on Chinese goods. U.S. exports to China plummeted from 985 million bushels in 2024 to just 218 million bushels in 2025, according to a WEF timeline, leaving American farmers with surplus crops and prices falling below $9 per bushel-a level not seen in years, Farmers Advance reported.

The American Soybean Association has warned that without a trade deal, farmers could face losses of up to 14 million to 16 million tons in exports, Agrinews reported. This crisis is compounded by China's strategic leverage: its procurement decisions are now handled by private companies, which have shown little urgency to resume U.S. purchases, an Archyde analysis notes.

APEC Summit: A Make-or-Break Opportunity

The APEC summit in South Korea represents a critical juncture. According to Reuters, President Trump has emphasized that soybean exports will be a central topic during his meeting with Xi Jinping. The negotiations are expected to address two key issues:
1. Tariff reductions: Both sides have hinted at potential cuts to tariffs, which currently stand at 125% in the U.S. and 34% in China on soybeans, Brookings analysts note.
2. Import quotas and purchase commitments: The U.S. is seeking assurances that China will resume large-scale soybean purchases, potentially securing 367 million bushels to meet USDA targets, Archyde reported.

However, China appears to be leveraging its position to demand a "fairer and more balanced outcome," as noted by Brookings analysts. This suggests that any agreement may require U.S. concessions on issues beyond soybeans, such as tech export controls or rare earth mineral access, as tracked by the WEF timeline.

Investment Implications: Navigating Volatility

For investors, the soybean market's volatility hinges on the outcome of these negotiations. If a deal is reached, soybean prices could stabilize or even rise as China resumes purchases. Conversely, a breakdown in talks risks further price declines, as U.S. farmers struggle to compete with South American suppliers, according to Farmers Advance.

A Bloomberg analysis highlights the dual risks:
- Short-term: Soybean futures are likely to remain volatile until the APEC summit concludes, the WEF timeline notes.
- Long-term: A prolonged trade war could permanently shift global supply chains, with China relying on Brazil and Argentina for soybean needs, Archyde observed.

Investors should also monitor the U.S. Department of Agriculture's (USDA) crop reports and China's import data for real-time signals. Hedge funds and commodity traders are already positioning for a range of scenarios, with some betting on a 10% price surge if tariffs are reduced, Brookings suggested.

Conclusion: A Geopolitical Crossroads

The U.S.-China trade negotiations at the APEC summit are more than a diplomatic exercise-they are a test of whether geopolitical tensions can be managed without catastrophic economic fallout. For soybean markets, the stakes are clear: a resolution could revive U.S. exports and stabilize prices, while a failure risks deepening the crisis for American farmers and global supply chains.

As the October 31 deadline approaches, investors must weigh the likelihood of a deal against the broader geopolitical landscape. In a world where trade policy and commodity prices are inextricably linked, the soybean market remains a litmus test for the health of U.S.-China relations.
