Cetes Rebound on Higher Inflation and Uncertainty Over Banxico’s Next Move

March’s inflation uptick halted the decline in yields and renewed the appeal of Cetes, as the market reassesses the pace of Banxico rate cuts.

Cetes yields stopped falling and posted increases in the latest auction, at a time when inflation has accelerated again and the market is adjusting its bets on the path of Banco de México (Banxico) monetary policy. For savers, the shift matters: even with rates that have been easing from their peaks, short-term government instruments still offer nominal returns above the overall rise in prices.

At the auction, the 28-day Cete was essentially unchanged at 6.81%, while the 91-day rose to 7.11%. The 182-day paper came in at 7.28%, and the two-year Cete reached 8.57%—a move that points to a larger adjustment at longer maturities, where the market typically prices in uncertainty about future inflation and the trajectory of the policy rate more aggressively.

The backdrop is the rebound in inflation in the first half of March, driven by pressure in certain food and energy categories, as well as services with strong seasonal sensitivity. For Banxico, the combination of higher headline inflation and a still-sticky core measure tends to complicate the debate over additional cuts: even if economic activity shows signs of slowing, the central bank generally prioritizes bringing inflation back to target and keeping expectations anchored.

This shift in tone is also showing up in the market: when inflation surprises to the upside, rates on instruments like Cetes tend to stabilize or move higher because investors demand a bigger premium to preserve purchasing power—especially over horizons of several months or years. By contrast, when disinflation looks more firmly established, yields typically drift lower.

What it means for saving: real returns, maturities, and strategy

Beyond the nominal yield, the key point for savers is the real rate—what’s left after subtracting inflation. With annual inflation around the mid-single digits and Cetes near or above 7% across several tenors, the real return remains positive, though it varies depending on the maturity and the timing of the purchase. In practical terms, an attractive real yield typically supports demand for government debt, especially among conservative investors looking for liquidity and low credit risk.

Maturity selection matters. During periods of uncertainty about inflation or Banxico’s near-term decision, some investors prefer shorter tenors (28 or 91 days) so they can reinvest sooner and adjust their strategy if rates change. Others choose longer maturities when they want to lock in a return in anticipation that rates could fall later on. The relatively larger increase in the two-year Cete suggests that, for now, the market is demanding extra compensation for the risk that disinflation proves less linear or that monetary policy remains restrictive for longer.

At the same time, Cetes compete with other saving options in Mexico. Bank CD rates or fixed-term deposits can be competitive in some cases, but they often depend on the amount invested and the customer’s profile. Meanwhile, long-term retirement-linked vehicles may post higher returns in certain periods, though they’re different by nature: longer horizon, more volatility, and investment goals that aren’t directly comparable to a short-term debt instrument.

Looking ahead, the evolution of prices will be decisive. If inflation cools in the coming months and core inflation confirms a downward trend, the market could once again price in gradual cuts, putting downward pressure on yields. But if shocks persist in food, energy, or services—or if expectations appear not fully re-anchored—Banxico could opt for a longer pause, keeping rates relatively high and preserving Cetes’ appeal for conservative profiles.

In perspective, the recent move in Cetes reflects a rebalancing between inflation, expectations, and monetary policy: for savers, the main takeaway is that yields are still offering a partial hedge against lost purchasing power, but the maturity chosen—and close monitoring of inflation—will be decisive in the months ahead.
