The Fed returns to monetary tightening after more than three years without an increase. Indeed, the US central bank raised its rates by 25 basis points, bringing their range to 3.75% - 4.00%, a first since July 2023. This decision is motivated by persistently high inflation, yet it did not automatically shake bitcoin. Despite a spike in volatility after the announcement, BTC stabilizes around 76200 dollars. Between monetary tightening and crypto market resistance, the Fed's decision now raises the question of the trajectory of rates.
