Fixed-income markets experienced an immense wave of relief on 15 May, as the April consumer price index printed at 3.4 per cent year-on-year, while core prices slowed to 0.3 per cent month-on-month—the first deceleration in four months. Benchmark ten-year yields tumbled, and rate-cut wagers were immediately restored to the forward curve.

Yet fixed-income allocators should exercise analytical restraint before declaring disinflation back on track. A single month of modest deceleration does not establish a trend, particularly when shelter costs remain elevated and base effects turn adverse in the second half of the year. The Federal Reserve will demand several consecutive months of confirming data before validating market easing expectations.

A single cooler inflation print provides welcome relief for duration assets, but central bankers will not execute a monetary pivot on the back of one month of statistical progress.
