What the table shows
The table applies past USD/MXN moves since 1999 to the latest closing rate, giving a historical base rate for how wide a normal year has been. A higher number means a stronger dollar and a weaker peso.
It is not a forecast or advice. A normal year here is a historical reference, and the next year can fall outside it. Each column uses past runs matching its horizon, including 40 trading days for the period to year end.

How past moves become ranges
For each horizon, we take every overlapping run with the same number of trading days since 1999 and calculate its percentage change. The 12-month calculation contains 6,877 runs.
We take the tenth, twenty-fifth, fiftieth, seventy-fifth and ninetieth percentiles of those changes and apply them to 18.65. The middle is the median, while the outer reference points each leave one in ten runs beyond them.
The past does not repeat exactly, and overlapping runs are not independent. By definition, two in ten runs ended outside the band, so it does not contain all rare shocks.
Recent and long-run volatility
Annualised volatility is 8.2% over the last year, compared with 12.5% across the full history. When the recent figure is above the long-run figure, wider moves have been more common recently; when it is below, narrower moves have been more common.
What moves the dollar against the peso
The gap between the Federal Reserve's rate and the Bank of Mexico's rate affects the appeal of peso and dollar holdings. Most Mexican exports go to the United States, so US demand, oil prices and money sent home by Mexican workers abroad feed into demand for pesos.
The peso is traded heavily by investors who want exposure to emerging markets, so swings in risk appetite can move it quickly.
How this differs from published forecasts
Banks and research firms publish forecasts for different horizons, including year-end targets, quarterly averages and rates 12 months ahead, and revise them as conditions change. This page does not reproduce those forecasts.
A published forecast is one view of the future. The table is the spread of what has happened, expressed at the latest closing rate.
