In only four days, the dollar has strengthened 77 cents to reach a historic peak of $17.47 pesos, according to data from Grupo Financiero Banamex.
The dollar seems poised to get even higher during the week, after the minutes of the last monetary policy meeting of the Federal Reserve last Wednesday were made public.
The interbank wholesale exchange rate broke the psychological roof of $17.00 pesos to be sold at $17.12, 71.8 cents above last Wednesday's quote, according to the Bank of Mexico.
The fear on the slowdown in the Chinese economy and its global impact, as well as the collapse in the international prices of oil are the main triggers for this strengthening of the dollar.
