Mexico’s central bank has done a “good job” in helping guide the economy and the inflation rate will probably near its 3 percent target toward the middle of next year, Governor Agustin Carstens said. A change in the way gasoline prices are fixed will help curb the rise in broader consumer costs, Carstens said in an interview with El Financiero-Bloomberg TV, according to a transcript. Favorable comparisons with inflation this year, when the nation implemented a tax increase, will also help lower the annual rate starting in January, he said. Stable inflation expectations have allowed policy makers to lower interest rates to boost the economy in the absence of pressures on core inflation, which excludes farm and energy costs, Carstens said. Policy makers cut borrowing costs 1.5 percentage points in a 15-month period to 3 percent, the lowest in Latin America, to revive an economy that struggled to bounce back from its weakest expansion since 2009.
