Czech Mortgage Rates Are Rising — What Expats Should Do Now

What Is Happening to Czech Mortgage Rates

Mortgage rates in Czechia have been climbing through 2026. According to the Swiss Life Hypoindex, the average offered rate rose for the sixth month in a row in September, to 5.51% — the highest level since the summer of 2024. In October it moved up again, to roughly 5.8%.

One detail matters for your decision: banks have been making longer fixations more expensive faster than short ones. A one-year fixation has been cheaper than the longer options, which changes the usual trade-off between price and certainty.

Why Rates Are Going Up

The Czech National Bank turned hawkish

In June 2026 the CNB raised its two-week repo rate to 3.75%, its first increase since 2022, and left it unchanged at the August meeting. Check cnb.cz for the latest decision before you plan around it.

But swaps matter more than the key rate

Czech banks price mortgages off interest rate swaps on the interbank market — in effect the price of money over several years. Swap rates react to inflation expectations, energy prices and global events, and they often move before the central bank does. That is why mortgage rates can rise even when the CNB is not changing anything.

Banks are pulling back on discounts

After a period when some lenders cut rates to win customers, banks now face higher funding costs and have less room for broad discounts. Different banks have chosen different strategies, so the gap between the cheapest and the most expensive offer is worth checking.

What It Means for Your Monthly Payment

A difference of one percentage point sounds small. Over a 30-year loan it is not. Here is an example of a 5,000,000 CZK mortgage repaid over 30 years:

You can borrow less than before

Higher rates also reduce the size of the loan your income can support. Take a household that can comfortably pay 35,000 CZK a month over 30 years: at 4.5% that supports a loan of about 6.9 million CZK, at 5.5% about 6.2 million, and at 6% about 5.8 million. Between 4.5% and 6% that is roughly one million CZK less purchasing power. Banks monitor your DSTI — total loan repayments relative to net income — so a higher rate can push you over a bank's internal threshold sooner.

What You Can Do Now

1. If you are buying: secure the rate early

Many Czech banks offer a rate guarantee with a pre-approval or application, valid for a limited period that differs by bank. If you are actively looking, this protects you against further increases while you search and negotiate. Our step-by-step mortgage guide explains why we recommend starting with pre-approval.

2. Think carefully about the fixation

• Shorter fixation (for example 1–3 years): often cheaper today, but you renegotiate sooner at a rate nobody can predict.
• Longer fixation (5 years and more): a higher rate today in exchange for a payment you can plan around.

There is no universally right answer. The deciding questions are how much room your budget has if the rate is higher at renewal, and whether your income and plans are stable over the period. This is exactly what we model with clients before they choose.

3. If your fixation is ending: start early

Begin comparing offers months before the end of your fixation. You can usually stay with your current bank and negotiate, or refinance with another bank. Compare the total cost, including fees and the discounts tied to a bank account, insurance and property cover, not only the headline rate.

4. Check your numbers against DSTI

Before you commit to a property, calculate what the loan costs at today's rates and at a rate one percentage point higher. If the second number is uncomfortable, you may want a smaller loan, a larger down payment or a different fixation.

5. Use a broker who compares the whole market

Banks have reacted differently to the same market, so the difference between the best and worst offer can be large. We work with Česká spořitelna, ČSOB, Komerční banka, UniCredit Bank, Raiffeisenbank, Oberbank and mBank and compare them for you, in English, including all the paperwork in Czech.

Frequently Asked Questions

Will Czech mortgage rates go down soon?

Nobody can predict it reliably. Mortgage rates follow interest rate swaps more than the central bank's key rate. Analysts quoted in the September 2026 Hypoindex release advised against counting on a quick return below 5%.

Should I choose a short or a long fixation now?

It depends on your budget and how much uncertainty you can live with. In autumn 2026 banks were raising longer fixations faster than one-year ones, so a short fixation can be cheaper today but means renegotiating sooner at an unknown rate.

Can I lock in a mortgage rate before I find a property?

Many Czech banks offer a rate guarantee with a pre-approval or application, valid for a limited period that differs by bank. Ask for the exact conditions in writing.

How do higher rates affect how much I can borrow?

A higher rate means a higher payment for the same loan, so the maximum loan that fits within the bank's DSTI limit becomes smaller. See the example above.

My fixation ends soon. What should I do?

Start comparing offers months in advance. You can usually stay with your bank and negotiate, or refinance with another bank. Compare total cost, not only the headline rate.
