Mexican peso falls 9% over five weeks against the US dollar
The Mexican peso weakened against the US dollar for a fifth consecutive week, losing about 9% over that period.
On Friday, it ended at 18.4111 pesos per dollar, down 1.15% from the previous day.
The decline followed minutes from Mexico’s central bank, which said three of its five board members saw room for more rate cuts if the inflation outlook improves.
Mexico’s interest rates have helped support the peso, but that advantage has narrowed after a US rate increase.
The currency’s drop matters because changes in interest rates can affect demand for the peso and the cost of dollars in Mexico.
One market analyst warned that exchange-rate swings could push the dollar above 19 pesos, while traders are watching 18.50 as a resistance level.
Further moves will depend in part on how expectations for interest rates in Mexico and the United States change.
