Brendan O'Boyle By Brendan O'Boyle MEXICO CITY, May 7 (Reuters) - The Bank of Mexico cut its benchmark interest rate in a split decision on Thursday and said it was ending an over two-year-long easing cycle as it balances concerns over above-target inflation with pressure to revive Mexico's slowing economy. The 25 basis point cut brings the rate to 6.50%, its lowest since May 2022.
