How Banxico's Rate Affects Your Mortgage

The relationship between the Banxico rate and your mortgage is one of the most common questions among people about to apply for a home loan. The Banco de México (Banxico) sets a benchmark rate that influences the cost of money across the entire financial system, including the banks that offer mortgage loans. When that benchmark rate goes up or down, banks usually adjust, with some delay, the rates they offer to new loan applicants, although the exact effect can vary by institution and by the type of mortgage product.

How this relationship works in practice

When Banxico raises its benchmark rate to control inflation, banks' funding costs tend to rise, and that usually shows up as higher mortgage rates on new loans, especially variable-rate ones. Conversely, when the benchmark rate falls, banks may offer more attractive terms to win new customers. It's important to note that if you already have a fixed-rate loan, Banxico's moves don't change your monthly payment; the effect is felt mainly on new loans or variable-rate loans, as well as on other financial products indirectly tied to the benchmark rate.

What you can do as a buyer or borrower

In the face of benchmark rate movements, you have several options to consider before and after taking out your loan:

• Compare offers from several banks before signing, since the adjustment is not the same across institutions.
• Prefer a fixed rate if you want certainty in your monthly payments throughout the life of the loan.
• Consider mortgage portability (transferring your loan to another bank) if your current loan ended up with an uncompetitive rate.
• Simulate different rate scenarios before committing to a long term.
• Check whether your bank offers the option to restructure terms when the benchmark rate falls steadily.

Fixed vs. variable rate in the face of Banxico's moves

Choosing between a fixed and a variable rate is one of the most important decisions when taking out a mortgage, especially in periods when Banxico's rate moves frequently. A fixed-rate loan protects you from future increases, but it usually starts with a slightly higher rate than the variable one at the time of signing. A variable-rate loan can be cheaper at the start if the benchmark rate is at low levels, but it exposes the borrower to higher monthly payments if Banxico decides to raise its rate later. The right decision depends on the loan term, your risk tolerance, and the economic outlook at the time you sign.

Frequently asked questions

If Banxico lowers its rate, does my mortgage automatically go down?

Not automatically or immediately; it depends on the type of loan you have. Fixed-rate loans don't change, while variable-rate loans may adjust with some delay depending on the bank.

Is it worth waiting for Banxico's rate to drop before buying a home?

It depends on your situation; waiting can mean missing out on price opportunities on the property, while buying now with a fixed rate protects you from future increases, so it's worth weighing both sides calmly.

Can I switch my loan from a variable rate to a fixed rate after signing?

Some banks offer that option through restructuring or portability to another institution, but the conditions and associated costs may vary, so it's best to check directly with your bank.
