USD/MXN Exchange Rate History: Peso per Dollar Since 1993

The Mexican peso is one of the most liquid emerging-market currencies and a favourite carry-trade vehicle, tied closely to the US economy and to oil. This dataset tracks the Federal Reserve H.10 rate, expressed as Mexican pesos per US dollar, distributed via FRED under the code DEXMXUS, with daily coverage since 1993. A higher number means a stronger dollar and a weaker peso.

The full dataset is available in CSV and Excel formats — daily observations spanning 1993–2026.

FRED Direct CSV Access

The underlying data is published in the Federal Reserve Economic Data (FRED) database under the series code DEXMXUS, sourced from the Federal Reserve Board’s H.10 release:

Methodology

The Federal Reserve reports the Mexican pesos per US dollar noon rate in its H.10 release; the series begins in 1993, with the introduction of the new peso.

The Federal Reserve publishes these rates daily in its H.10 release. Values are indicative noon or end-of-day rates, not transactable quotes, and there are no observations on weekends or US holidays. The series begins in 1993.

This dataset is updated via an automated pull from the FRED API (series DEXMXUS) by an Eco3min pipeline running on GitHub Actions, which regenerates the cleaned CSV and Excel files and refreshes the page metadata.

Data Quality & Provider Notes

The Federal Reserve H.10 rates are a standard, widely cited reference for bilateral exchange rates. A few provider-specific points matter when using this series.

• Indicative, not transactable. H.10 rates are reference rates collected at a set time of day. They will differ from the bid/ask a trader actually deals on, and from other fixings (ECB, WM/Refinitiv 4pm London).
• Gaps on non-business days. There are no observations on weekends or US public holidays, so the series is not strictly continuous in calendar time.
• Bilateral, not trade-weighted. This is a single currency pair. It is not the broad, trade-weighted dollar index, which aggregates many bilateral rates.
• Discontinued or restated quotes. The Federal Reserve has occasionally changed how a rate is reported; treat very long histories as broadly consistent rather than methodologically identical throughout.

Common Pitfalls When Using This Series

1. Reading the quotation direction backwards. This series is Mexican pesos per US dollar, so the number rises when the dollar strengthens and falls when the peso strengthens. Mexico redenominated to the ‘new peso’ in 1993 (dropping three zeros), so this series is not comparable to pre-1993 peso quotes. Getting the direction wrong inverts every move and every regime described below.
2. Treating gaps as missing data. Weekends and holidays have no H.10 observation; this is by design, not a data error. Resample carefully before computing returns.
3. Confusing a bilateral rate with the dollar’s overall strength. One pair can move on currency-specific news while the broad, trade-weighted dollar barely moves, and vice versa.

Historical Regimes

1993–1994 — New peso and Tequila crisis. Mexico introduced the ‘new peso’ in 1993; the December 1994 Tequila crisis then roughly halved its value.

1995–2008 — Stabilisation. After an IMF-led rescue, the peso stabilised and traded in a relatively orderly range.

2008–2016 — Crisis and oil. The 2008 crisis and the 2014-2016 oil slump, Mexico being an oil exporter, weakened the peso.

2016–2020 — Trade-policy volatility. NAFTA renegotiation and US trade rhetoric drove sharp swings.

2021–2026 — ‘Super peso’ and reversal. Nearshoring and high carry made the peso a standout performer before political and tariff worries reversed some gains.
