If you want to understand why the peso moves, start with Banxico. The Bank of Mexico sets the reference interest rate, and its eight scheduled decisions per year are the biggest calendar events for anyone watching USD/MXN. Everything else — oil, nearshoring, US politics — plays out against the backdrop of where Banxico and the Fed have set their respective policy rates.
What is Banxico?
Banxico — formally Banco de Mexico — is Mexico's central bank. It was founded in 1925 and granted full political autonomy in 1994 following the Tequila Crisis. Its legal mandate, written into Article 28 of the Mexican Constitution, is to preserve the purchasing power of the peso. In practice that means keeping inflation close to its 3% target, with a tolerance band of plus or minus one percentage point.
Banxico is headquartered in a distinctive building on Avenida 5 de Mayo in central Mexico City. It is the Mexican counterpart of the US Federal Reserve, though the structure is simpler: there are no regional banks, and monetary policy is decided by a single five-member committee called the Junta de Gobierno, or Governing Board.
How Banxico sets interest rates
The Governing Board has a governor and four deputy governors. Each is appointed by the president of Mexico and confirmed by the Senate for staggered six-year terms. This staggering is deliberate — no single president can replace the entire board, which protects Banxico from short-term political pressure.
The board holds eight scheduled monetary policy meetings per year, roughly every six to seven weeks. At each meeting it votes on the target for the overnight interbank rate, known as the tasa de interes objetivo. The decision and a short statement are published at 1:00 p.m. Central Time, usually on a Thursday. Two weeks later Banxico publishes the full minutes, including how each member voted and the main arguments. Every three months it also publishes a Quarterly Report with GDP and inflation forecasts.
Why Banxico decisions move the peso
The peso is a classic "carry trade" currency. Global funds borrow in low-rate currencies like the Japanese yen or US dollar and park the money in higher-rate currencies like the peso, pocketing the rate differential. In April 2026 the spread between Banxico's policy rate and the Fed funds rate is roughly 4 percentage points — enough to make MXN attractive, but tight enough that small changes matter.
When Banxico sounds more hawkish than the Fed — holding rates steady while the Fed cuts, or hinting at a slower easing path — the differential widens and the peso strengthens (fewer pesos per dollar). When Banxico cuts faster than the Fed, the differential narrows and the peso weakens. A single 25-basis-point surprise in the Banxico statement can move USD/MXN by 0.5% to 1% within minutes, and by 1% to 2% over the following 24 hours once traders digest the forward guidance.
A typical Banxico decision day
Here is roughly what the day looks like if you watch the screens:
- Morning (Mexico City): USD/MXN trades in a narrow range. Volatility is usually the lowest of the week as traders square positions.
- 12:45 p.m. CT: Final positioning. Volumes thin out sharply in the last 15 minutes before the release.
- 1:00 p.m. CT: The decision and statement hit the wire. Algorithmic traders react in under a second; the first big move usually comes inside the first 10 seconds.
- 1:00 to 1:15 p.m. CT: Main reaction. The peso can move 0.5% to 1.5% as traders parse the statement word by word. This is the widest-spread window of the whole week at retail exchange counters.
- 1:15 p.m. to close: Secondary moves as analysts publish takes and positioning adjusts.
- Next day and beyond: Further moves as global desks in London and Asia weigh in. Two weeks later, the minutes can trigger a smaller but noticeable move.
The 2023–2024 rate cycle
A quick recap helps put the 2026 picture in context. Between 2021 and early 2023, Banxico hiked the policy rate from 4.00% to a peak of 11.25%, matching and eventually outpacing the Fed. The combination of Mexico's high real rates, strong remittance flows and booming nearshoring investment produced the so-called "super peso" — the rate fell as low as 16.30 per dollar in mid-2024, the strongest level since 2015.
Banxico then began a cautious easing cycle in early 2024, cutting in 25-basis-point increments. By the start of 2026 the policy rate was around 8.50% and Banxico continued to guide markets toward further, slow cuts. The peso has given back some of the super-peso gains and now trades in a 16.80 to 18.20 range against the dollar.
Key phrases to watch in Banxico statements
Central bank language is deliberately dense. A few phrases do most of the signaling work:
- "Balance of risks" for inflation — if the balance shifts from "to the upside" to "balanced", the board is opening the door to cuts.
- "Restrictive stance" — as long as policy is described as restrictive, Banxico believes rates are still above neutral.
- "Forward guidance" phrases such as "considering further adjustments" or "evaluating the magnitude and timing" — these are the single most market-moving words in the statement.
- "Inflation trajectory" — the board's view on whether inflation is converging to the 3% target on schedule.
- "Unanimous" vs "by majority" — a split vote, especially a 3–2 dissent, signals that a policy change is likely at the next meeting.
How to track Banxico meetings

- Financial news economic calendars — Reuters, Investing.com and Forex Factory list every Banxico decision with consensus expectations and the previous value, which is what moves markets.
- Your broker's economic calendar — IBKR, Charles Schwab, Saxo and most Mexican brokers flag Banxico meetings. If you have rate alerts set up on Wise or Revolut, switch them on for the 48 hours around each decision.

Should regular people care?
If you are only changing $200 for a weekend in Playa del Carmen, the answer is no — Banxico noise is rounded away by the counter spread. If you are sending $3,000 a month in remittances, buying a condo in Mexico, or running payroll for a Mexican subsidiary, the answer is yes. Timing a transfer on the right side of a Banxico decision can shift the rate you get by 0.5% to 1.5%, which is $15 to $45 on a $3,000 transfer and thousands of dollars on a property purchase.
The simple rule for non-traders: do not transfer in the 24 hours before a Banxico decision. Wait until the dust settles on decision day afternoon, or transfer earlier in the cycle.
