Mexico's annual inflation accelerated more than expected in February to surpass the central bank's target range, official data showed on Monday, with analysts expecting the inflationary pressure to delay further interest rate cuts. Consumer prices in Latin America's second-largest economy rose 4.02% in the year through February, according to national statistics agency INEGI, above the 3.94% increase expected by economists in a Reuters poll, and up from 3.79% the previous month.
