As we enter May 2026, the global FX market is attempting a difficult high-wire act. April was defined by “civilisation-ending” ultimatums and a Pakistani-brokered ceasefire that sent Brent crude on a rollercoaster from US$110 down to the mid-US$90s.
For traders, the connect-the-dots moment is this: the peak panic around the Iran conflict has faded, but it has been replaced by a structural regime shift. Markets may be moving from a war premium to a transition premium.
With Kevin Warsh nominated to take the Fed chair in mid-May and the Bank of Japan (BOJ) staring down a generational ceiling near 160.00, the calm in the headlines may be masking a major repricing of global yield differentials.
Strongest mover: US dollar (USD)
The US dollar enters May with a new kind of ballast. While the ceasefire reduced the immediate need for a panic hedge, the nomination of Kevin Warsh, widely viewed as an inflation hawk, has provided a structural floor for the greenback.
Weakest mover: Japanese yen (JPY)
If you wanted to design a currency to struggle in 2026, the yen fits the brief. Despite the “TACO” script, short for “Trump always chickens out”, providing some relief to equities, the mathematical pressure on JPY remains significant.
Data to watch next
Four events stand out as the clearest catalysts. Each has a direct transmission channel into rate expectations.
