LONDON—The Swiss franc soared on Thursday after the Swiss National Bank delivered a surprise interest rate hike, triggering its biggest daily jump against the euro since the central bank ditched its currency peg in 2015.
The SNB joined other central banks in tightening monetary policy to fight surging inflation in its first rate hike in 15 years, increasing its policy rate to -0.25 percent from the -0.75 percent level it has deployed since 2015.
