Six central banks overseeing the ten most heavily traded currencies left rates unchanged in April due to inflation pressures and volatile markets caused by the Iran war.
Since the war began on February 28, oil prices have surged, lifting global inflation expectations through higher energy costs.
In the year to end-April, G10 central banks delivered no rate cuts and 50 basis points of hikes across two moves by Australia.
Compared to 2024 and 2025, when G10 banks delivered 850 and 800 bps in easing respectively, April marked a sharp reversal.
Among emerging economies, only two of 18 cut rates in April, the first time the monthly tally of cuts fell below 100 bps in a year.
The Philippines raised rates to keep a lid on rising inflation, while currencies in Asia flirt with or hit fresh record lows.
Analysts note central banks are in a better starting position than in previous crises, with positive real rates and room to act.
