Effects of the Iran conflict on fuel, fertilizer, and food prices in Nigeria

Nigeria faces a new wave of economic pressure from the ongoing Iran conflict, with disruptions around the Strait of Hormuz causing sharp increases in global oil and fertilizer prices and threatening to reverse the recent decline in Nigeria’s food inflation. Although Nigeria could benefit from higher oil and fertilizer export revenues due to its expanding domestic refining and urea production capacity, the country remains heavily dependent on imported refined fuel, potash, phosphate, and other fertilizer inputs. Rising transport, logistics, and production costs are already increasing pressure on farmers, food systems, and household welfare. At the same time, however, the crisis presents a strategic opportunity for Nigeria to strengthen domestic refining, expand fertilizer production, deepen regional trade, and reposition itself as a major supplier of fuel and fertilizer across Africa.

Haunted by tariffs and trade wars: A positive trade policy for US agriculture

US farmers have been among the biggest beneficiaries of US free trade agreements and the postwar creation of a rules-based global trading system. Under recent administrations, however, farmers have been disadvantaged by the US shift away from forging such trade pacts. Agriculture has also been one of the sectors most affected by the volatility and uncertainty of the first and second Trump administrations’ high tariffs and trade wars. Both Trump administrations have compensated farmers for lost export revenue, but such a trade policy is not a sustainable long-term solution and cannot replace a more positive policy that improves trade rules and expands farmers’ market access abroad.

Report

Evaluating the impact of tariffs on US agriculture a year after liberation day

2026Glauber, Joseph W.

Evaluating the impact of tariffs on US agriculture a year after liberation day

In April 2025, the Trump administration levied 10 percent tariffs on virtually all countries and higher “reciprocal” tariffs on certain countries, ushering in a new and uncertain tariff architecture that saw significant changes, exemptions, and additional actions over the following year. The tariffs modestly reduced overall US agricultural and food imports, but with significant heterogeneity by exporting country and product category. The tariffs had mixed effects on US agricultural exports, with exports to China and Canada falling partly because of retaliatory tariffs and consumer reactions, respectively. After imposing the tariffs, the United States negotiated several bilateral trade deals with other countries. However, given the lack of product-specific details, China’s continued retaliatory measures, and the Supreme Court’s decision striking down the bulk of US tariffs, it is unclear whether these deals with actually improve agricultural market access for US exporters.
