On Wednesday in Washington, Kevin Warsh will chair his first Federal Reserve rate decision — a meeting that carries unusual political weight. Warsh was personally selected by President Donald Trump, who has used Truth Social to demand that America maintain the "LOWEST RATE of any country in the World" and has urged Fed governors to "BE PATRIOTS." The pressure is striking in its bluntness, yet the data is pulling firmly in the opposite direction: annual US inflation held at 3.4% in the most recent reading, well above the Fed's 2% target, which has not been met for more than five years.

Warsh himself acknowledged in a recent speech that, without continued progress toward that target, policymakers would have "work to do." The energy market is making that work considerably harder. Crude oil surged past $100 per barrel last week — its highest price since July — after the US-Iran conflict escalated and the Strait of Hormuz remained largely closed to tanker traffic. Houthi rebel advances along the Red Sea coast are simultaneously threatening Saudi export routes, squeezing global supply from two directions at once.

Oil prices retreated slightly on Friday on hopes of renewed diplomatic talks, but analysts warn that any sustained closure of those waterways will feed directly into consumer prices across the Northern Hemisphere this autumn. Across the Atlantic, the Bank of England is expected to hold its benchmark rate at 3.75% on Thursday, though the decision is far from unanimous. Three of the nine members of the monetary policy committee voted for a rise as recently as July, and Friday's stronger-than-expected UK growth figures could harden that minority position.

Thomas Pugh, chief economist at consultancy RSM, has warned that renewed energy price pressure compounds an already uncomfortable inflation picture for Andrew Bailey's committee. In Tokyo, the Bank of Japan faces its own dilemma — whether to tighten further and risk stalling a fragile recovery, or to hold and watch the yen weaken.
