The Mexican peso reached an exchange rate of 18 to the U.S. dollar on Monday, marking a 1.3% decline from the previous Friday closing rates. The Bank of Mexico reported a closing rate of 17.94 on the same day.
Why it matters
The decline reflects growing investor risk aversion and expectations for more restrictive monetary policy from the U.S. Federal Reserve. Additionally, volatility in oil markets following events at the Strait of Hormuz has contributed to broader financial shifts.
The peso hit 18 to the dollar on Monday, a level not seen since March 31. This represents a 6% depreciation from the month's strongest position of 16.89 reached on September 4.
