The benchmark stock index surged 1.8% Friday to close at a record high, extending its winning streak to five consecutive sessions following the release of government data showing that consumer prices rose 0.1% in March, well below analyst forecasts of 0.3%. The annual inflation rate fell to 2.6%, its lowest reading since early 2023, in a development that investors interpreted as significantly raising the probability of a rate cut at one of the Federal Reserve's upcoming policy meetings.
Technology shares led the advance, with the sector gaining 2.4% as investors rotated into growth stocks that tend to benefit most from lower interest rates. Financial stocks also posted solid gains, while energy lagged behind. Trading volume was elevated, suggesting broad-based participation in the rally rather than narrow speculative buying — a sign that analysts said points to genuine conviction in the inflation narrative rather than short-term momentum chasing.
"This is a meaningful reading," said a senior economist at a major investment bank. "One data point doesn't make a trend, but two or three more like this and the Fed will be in a very different position by summer." Interest rate futures markets shifted sharply after the data release, with traders now pricing in a higher probability of at least two quarter-point rate cuts before year-end, up from roughly even odds the previous week.

Not all economists greeted the data with unqualified optimism. Several noted that services inflation — which excludes food and energy and is considered a more reliable gauge of underlying price pressures — remained elevated, suggesting that the final stretch of disinflation could prove more difficult than the headline figures implied. Housing costs, which make up a large portion of the consumer price index, have been slow to reflect the decline in market rents that began nearly a year ago.
For ordinary consumers, the reaction to the inflation data was more muted. While investors celebrated, surveys continue to show that a significant share of households feel the cumulative effect of two years of elevated prices has not abated meaningfully. Grocery bills, utility costs, and insurance premiums remain well above their pre-inflation levels in absolute terms, even as the rate of increase has slowed — a gap between statistical improvement and lived experience that economists acknowledge and politicians are struggling to bridge.
