Polymarket traders have reached virtual unanimity on a Bank of Mexico (Banxico) interest rate decrease at its March 21 meeting, with decrease shares trading at 100% implied probability amid sustained disinflation. Headline CPI eased to 4.40% year-over-year in February from 4.43% in January, while core inflation dipped to 4.54%, firmly within Banxico's 3% ±1% target band and supporting the central bank's recent 50 basis point cut to 11% in February—the first easing since 2021. Labor market softening and moderating services inflation reinforce trader consensus on further monetary policy accommodation. Realistic challenges include unexpectedly hot upcoming CPI data on March 8 or persistent peso weakness prompting caution, though current dynamics heavily favor continuation of the rate cut path.
