Federal Reserve Hikes Interest Rates for First Time Since 2023
✓ The market called it — resolved 25 bps increase.
Fed Decision in September?
Polymarket prices this 25 bps increase at 85%.
The Federal Reserve officially raised its target federal funds rate by 25 basis points following its September 2026 meeting, a decision that ends a period of rate stability and signals a more aggressive stance against inflation. This move, the first rate increase since 2023, was widely anticipated by economists and financial markets alike, with the prediction market showing a strong 85% probability for this outcome. The Federal Open Market Committee (FOMC) cited stubborn inflation as the primary driver behind the adjustment, a sentiment echoed by multiple financial outlets. The decision immediately puts the central bank at odds with some political figures, including former President Trump, who advocated for lower rates. While the initial impact on crypto prices was minimal, analysts suggest that future rate adjustments could significantly alter calculations on Wall Street.
Background
Leading up to the September FOMC meeting, economists had largely coalesced around the expectation of a rate hike. Reports from earlier in the month, particularly the Consumer Price Index (CPI) data, had cemented the view that a 25 basis point increase was all but guaranteed. This consensus built over a period where the market's odds for a rate increase steadily climbed, reflecting growing confidence in the Fed's hawkish trajectory. The central bank had been under increasing pressure to act, with inflation proving more persistent than initially projected, necessitating a shift from its previous accommodative monetary policy.

What to watch
With the Federal Reserve signaling a potential for at least one more rate hike this year, attention will now turn to upcoming economic data releases and future FOMC meetings. The immediate aftermath includes scrutiny over how the economy absorbs this tighter monetary policy, the reaction of equity and bond markets, and whether inflation figures begin to show signs of moderation. The interplay between monetary policy and political sentiment will also remain a key area of observation.
