The Mexican peso started the week with a 0.37 percent gain against the dollar, despite uncertainty over the lack of agreements between the United States and Iran.
The local currency closed at 17.27 pesos per dollar according to Bank of Mexico data. This represented a gain of 6.36 cents from the previous close.
At bank windows the dollar traded at 17.72 pesos, according to Banamex. Analyst Felipe Mendoza of EBC Financial Group noted that the absence of high-impact data will force the peso to track commodity currencies.
The dollar index fell 0.28 percent to 99.19 units. Among other emerging currencies, the Brazilian real advanced 1.17 percent.
