MEXICO CITY, April 29 (Reuters) - Mexico's Grupo Financiero Banorte, the bank with the biggest weight in Mexico's benchmark stock index, posted a first quarter net profit of 9.93 billion pesos ($512 million) on Monday, up 47 percent compared to the same period last year.
The quarterly result was also boosted by gains from the sale of Banorte USA, the bank said in a statement.
Banorte's current loan portfolio registered a year-on-year increase in the quarter of 22 percent to reach 762.10 billion pesos, amid growth in commercial, corporate and government lending.
The bank's past-due loan ratio, meanwhile, fell to 1.7 percent, from 1.9 percent in the first quarter of 2018, according to the results.
Shares of Banorte closed up 1.32 percent on Monday prior to the release of the first quarter results.
