Mexico finance minister says peso to strengthen

The Mexican peso should rise against the dollar after the central bank launched a surprise interest rate hike earlier this week, Finance Minister Luis Videgaray said on Friday.

"It is reasonable that (the peso) will strengthen in a gradual manner in the coming days and weeks," he told local radio, repeating comments from earlier. He declined to specify a particular level, saying the exchange rate should be determined by the market.

The peso fell 0.2 percent against the dollar in morning trading to 18.315, after hitting a monthly low of 17.962 on Wednesday after the move by the Bank of Mexico.
