War, inflation and agriculture: the hidden cost shaking global markets
Middle East tensions push oil and fertilizer prices higher, raising a key question: who will bear the cost for food, inflation and farm production?
On April 1, 2026, market executives at Citigroup warned that the Middle East conflict-following U.S. and Israeli attacks on Iran-is creating long-lasting economic effects beyond energy markets, extending into agriculture and global inflation. The key question now emerging among investors is clear: "Who pays for all this?"-and why it matters: because those costs will ultimately be passed on to food prices, interest rates and farm production worldwide.
Energy, fertilizers and food: the ripple effect hitting agriculture
Citi rates trading head Deirdre Dunn noted that oil has become the primary signal for markets, but emphasized that other commodities-especially fertilizers and aluminum-are increasingly critical to monitor.
Higher oil prices directly translate into rising agricultural input costs. Fertilizers, heavily tied to energy markets, are particularly exposed, putting pressure on farm margins across the United States, Brazil, Argentina and broader Latin America.
Markets are already pricing in a scenario of stickier inflation, forcing central banks to rethink rate cuts. In March, expectations shifted toward potential hikes, tightening financial conditions for farmers and agribusinesses.
From Wall Street to the farm: rates, debt and production pressure
According to Dunn, investors are beginning to accept that the conflict's impact will persist-even if tensions ease quickly. The energy shock is already feeding into the real economy, affecting production costs, insurance and infrastructure rebuilding.
For agriculture, this translates into higher borrowing costs, reduced investment in technology and increased pressure on production growth. Meanwhile, financial market volatility is boosting bank trading revenues but adding uncertainty to the broader economy.
At the same time, attention is turning to the U.S. fiscal outlook, with debt exceeding $31 trillion, potentially pushing long-term Treasury yields higher and reinforcing global interest rate pressure.
For the Americas, the outlook is mixed: stronger commodity prices may support exports, but rising costs and financial volatility threaten profitability and long-term competitiveness.
Ultimately, Wall Street's question is now a farm-level concern: the cost of war is no longer just about energy-it's embedded in food systems, inputs and global agricultural resilience.
