Economy and politics roundup: Oil, Fed and Turkey news - May 26, 2026

Global markets on May 26, 2026 were dominated by developments on the US–Iran front and a leadership change at the US central bank, driving sharp moves in oil, currencies and risk assets. Kevin Warsh’s installation as Federal Reserve chair and mixed signals on a possible reopening of the Strait of Hormuz pushed traders to reprice short-term supply risk and policy expectations.

The sequence of events included reports of US strikes on targets in southern Iran and media reports suggesting talks between Washington and Tehran about the possible reopening of key shipping lanes once a deal is reached; those competing headlines created whipsaw dynamics in crude markets as participants weighed the likelihood and timing of increased flows through the Hormuz corridor. The uncertainty around physical oil movements and timing of any agreement amplified volatility in both spot and futures contracts.

Market reactions were mixed: Brent and US crude traded with intraday reversals, equity indices showed uneven moves across regions, and government bond yields fluctuated as risk sentiment oscillated between improving and deteriorating scenarios. Traders noted that while some of the 'peace' optimism had been priced in, fresh military actions or setbacks could prompt rapid risk-off episodes, affecting commodity and currency portfolios.

In Turkey, the Treasury and Finance Ministry-chaired Financial Stability Committee convened to review domestic and external developments, concluding that the economy retains significant capital buffers and resilience against shocks. The committee’s statement was interpreted as an attempt to calm markets and signal policy coordination, although it did not announce immediate new measures. Local and international investors will monitor subsequent data and any regulatory steps closely.

Looking ahead, analysts expect continued headline-driven volatility: oil price swings tied to diplomatic progress or military incidents will likely feed into inflation expectations and thus central bank calculus, particularly for the Fed under its new chair. Market participants say they will watch physical flow updates through the Gulf, Fed communications from Kevin Warsh, and any domestic policy responses in Turkey to assess risk and adjust positioning.
