The euro and the British pound clung to modest gains on Thursday, recovering slightly from near one-week lows as foreign exchange markets balanced less-hawkish-than-feared Federal Reserve minutes against a fresh Middle East energy shock that threatened to cement a "higher-for-longer" interest rate paradigm.

The euro and the pound both firmed 0.1% in London trade, attempting to claw back territory after Wednesday’s declines were triggered by a dramatic geopolitical relapse that briefly sent traders scrambling for the safety of the greenback.

"The FX reaction was more muted, where the dollar was a little stronger, but the biggest impact was a jump in volatility and the unwinding of carry trade positions in the EM high-yielders," said Chris Turner, global head of markets at ING. 

Dollar steady as traders digest Iran tensions, Fed minutes 

The dollar index was flat on Thursday after a volatile overnight session.

The rapid swing in currency volatility highlights profound investor exhaustion across global trading desks.

Just weeks after a June 17 interim ceasefire agreement raised hopes of diplomatic stability, the sudden collapse of the deal - marked by U.S. President Donald Trump declaring the truce "over" and launching successive days of air strikes to open the Strait of Hormuz - shattered market complacency.

Yet, rather than fueling a prolonged rush into the safe-haven dollar, the geopolitical escalation collided with a surprisingly nuanced domestic narrative from Washington.

The slight retreat came after the minutes from the Federal Reserve’s June policy meeting revealed that officials were surprisingly divided over the necessity of further interest rate hikes, cutting through some of the market’s most hawkish fears.

While the Fed minutes provided a brief relief valve for European currencies, the greenback’s downside remained heavily restricted, keeping it within striking distance of recent 13-month peaks.

The primary transmission mechanism holding the dollar aloft is the commodity market. With crude oil prices surging on the back of Gulf military action, foreign exchange markets are forced to resurrect the threat of sticky, cost-push inflation.

Because Fed policymakers explicitly flagged inflation as their primary concern in the June minutes, any sustained energy shock increases the probability that the central bank will keep U.S. rates elevated well into the winter - a structural advantage that continues to support the dollar over its peers.

Meanwhile, the Japanese yen (USD/JPY) hovered precariously close to its weakest levels in 40 years. The persistent depression of the yen kept Tokyo authorities on high alert, with repeating warnings from government officials fueling intense speculation over an imminent physical currency intervention.

In other regional trading, the commodity-sensitive Australian dollar edged slightly higher, while the South Korean won remained flat amid heightened volatility in Seoul’s equity benchmarks.
