Mexican Peso Gains Ground: What is the Dollar Price Today, September 15?

The dollar is trading around 17.12 pesos this Tuesday, September 15, 2026, in a session marked by market caution ahead of the Federal Reserve’s (Fed) upcoming monetary policy decision. In the early hours of trading, the exchange rate shows limited movements as markets factor in various scenarios regarding U.S. interest rates.

Specifically, the Bank of Mexico (Banxico) set the FIX exchange rate at 17.1277 pesos per dollar, determined on Monday and published on Tuesday for obligations denominated in foreign currency within the country.

This movement occurs in an international scenario where energy prices are once again taking center stage. The

are up 1.58%, reaching $107.35 per barrel, while WTI is up 2.11%, at $103.53. The pressure on oil is linked to concerns about energy supply from the Middle East, a factor that can increase financial volatility and alter global inflation expectations.

Mexican Peso Faces Cautious Session Ahead of the Federal Reserve

The performance of the Mexican peso occurs as investors maintain their focus on the U.S. Federal Reserve. U.S. monetary policy has a direct influence on currency markets because decisions on interest rates can alter capital flows towards different assets and currencies.

On this occasion, the market is operating with caution before the Fed’s monetary policy decision is announced. This expectation helps explain why the peso’s movements are relatively contained during the early trading sessions.

Additionally, the dollar’s behavior against other currencies shows that the strength of the U.S. currency is not uniform. The dollar index (DXY), which measures the dollar’s performance against a basket of six developed economies’ currencies, is up 0.19% to 99.58 points. Similarly, the Bloomberg Dollar Index (BBDXY) is up 0.16%, trading around 1,196.85 units. This means the Mexican peso is managing to gain slightly even as the main dollar strength indicators register gains. This data is significant because it shows that the Mexican currency’s performance also responds to factors specific to emerging markets and Mexico itself.

Among the currencies experiencing the most significant depreciations during the day are:

The South Korean won, with a 0.88% drop.
The Taiwanese dollar, with a 0.50% decrease.
The Indian rupee, with a 0.42% decline.
The Japanese yen, with a 0.38% pullback.
The New Zealand dollar, with a 0.38% loss.
The Malaysian ringgit, with a 0.26% decrease.

In contrast, some emerging market currencies are showing gains against the dollar:

The Chilean peso is up 0.25%.
The Brazilian real is up 0.20%.
The Colombian peso is up 0.18%.
The South African rand is up 0.15%.
The Argentine peso shows a 0.09% advance.

Thus, the Mexican peso is part of a group of currencies that are managing to gain ground against the dollar on an international day characterized by caution.
