Mexican FinMin's resignation "unexpected, negative," says Goldman Sachs

The resignation of Mexico's finance minister is "an unexpected and negative development," Goldman Sachs wrote in a note to investors on Tuesday, adding that the move hinted at "significant policy and inter-personal frictions" in the government.

Mexican Finance Minister Carlos Urzua, a moderate and widely respected figure, resigned on Tuesday, citing deep differences over economic issues. The move dealt a blow to Mexican President Andres Manuel Lopez Obrador, who named a well-regarded deputy minister to replace him.
