Interest Rates in Poland 2026 — What They Mean for Your Finances

Quick Answer

The NBP (National Bank of Poland) reference rate stands at 3.75% as of mid-2026 — the RPP cut it by 25bp in March 2026 and has held it since (a pause through Q2). This brought mortgage costs down from their 2023-2025 peak (WIBOR 3M is now around 3.85%, versus ~5.8% a year earlier), while savings accounts and government bonds have stepped down accordingly. With CPI still near 4%, the RPP's guidance points to a pause — the next cut is realistically not before 2027.

Current NBP Interest Rates (mid-2026)

These rates have been in effect since the RPP's 25bp cut in March 2026, which ended the long hold that had run since October 2023. The Council has paused since.

How Interest Rates Affect Your Finances

Mortgages

For most people with a PLN-denominated mortgage, interest rates are the single biggest variable in their monthly budget:

• NBP reference rate influences WIBOR (Warsaw Interbank Offered Rate)
• WIBOR is the base component of your mortgage interest rate
• Your bank adds a margin on top (typically 1.5–2.5 percentage points)

With WIBOR 3M at 3.85% and a typical margin of 2.0%, total mortgage interest is about 5.85%. For a 300,000 PLN mortgage (25 years), that's roughly 1,900 PLN/month (€440).

The big relief already arrived: versus the 2024 peak (WIBOR ~5.8%, ~2,280 PLN/month) the same payment is now about 380 PLN/month lower. A further cut to 3.50% (WIBOR ~3.60%), if inflation cools, would shave only another ~40 PLN/month — most of the easing is behind us.

Savings Accounts & Deposits

Lower rates mean savers earn less than a year ago. Top promotional deposit rates in mid-2026 sit roughly around:

• 3-month deposits: ~3.5–4.0%
• 6-month deposits: ~3.8–4.5%
• 12-month deposits: ~3.5–4.0%

(Promotional offers vary by bank and conditions.)

But watch the real return. With CPI inflation near 4%, a ~4% deposit yields roughly 0% in real terms — and after the 19% Belka tax on interest income, you're slightly negative.

Government Bonds

Polish Treasury bonds indexed to inflation (EDO, COI) remain a popular long-term option:

• EDO (10-year): inflation-indexed (CPI + margin), first-year rate 5.35%, interest compounds annually
• COI (4-year): inflation-indexed from year 2 (CPI + margin), first-year rate 4.75%
• TOS (3-year): fixed rate, 4.40%
• OTS (3-month): fixed rate, 2.00%

EDO bonds are a commonly used vehicle for long-term inflation-protected savings in Poland, as their indexation is designed to keep returns above CPI.

When Will the RPP Cut Rates?

This is the million-zloty question. Here's what we know:

Arguments for cuts in 2026:

• Core inflation is declining (from a 7.7% peak to ~4% now)
• Economic growth is slowing — GDP below 3%
• Political pressure on the RPP is mounting
• The ECB maintains lower rates in the eurozone

Arguments against:

• Inflation remains above the NBP's 2.5% ± 1pp target
• Energy prices may rise when tariff shields expire
• The labor market stays tight — wage growth of 8–10% annually
• NBP President Adam Glapiński signals caution

Market consensus (mid-2026): The first 25bp cut already landed (March 2026, to 3.75%) and the RPP has paused since. Markets now price the reference rate flat at 3.75% through end-2026, with the next cut not before 2027 unless CPI (still ~4%) surprises lower.

What This Means for Your Financial Freedom Runway

Interest rates impact your Runway in several ways:

1. Debt servicing costs — higher rates = higher payments = shorter runway
2. Returns on savings — higher rates = better deposit interest = longer runway
3. Inflation dynamics — rates fight inflation, but too-high rates slow the economy
4. Property values — high rates cool the housing market, affecting your net worth

The key metric to track is the real interest rate (nominal minus inflation). If your deposit pays ~4% and inflation is ~4%, your money barely grows in real terms.

How to Prepare for Rate Changes

If you have a mortgage:

• Don't wait for cuts — build a financial buffer now
• Consider overpayments if you have surplus cash
• Check whether your mortgage uses WIBOR 3M or 6M — this affects how often your rate adjusts

If you're saving:

• Short-term deposits (3–6 months) give flexibility before potential cuts
• EDO bonds (10-year) are a long-term option designed to protect against inflation
• Consider a deposit ladder — spread savings across different maturity dates

If you're planning to buy property:

• Rate cuts will increase borrowing capacity but may push up property prices
• Don't try to time the market — buy when you're financially ready
• Calculate how your payment changes under different rate scenarios

Understanding the WIBOR-to-WIRON Transition

Poland is transitioning from WIBOR to WIRON (Warsaw Interest Rate Overnight) as its benchmark rate, planned for completion by 2027. For mortgage holders:

• Existing WIBOR-based mortgages will eventually convert to WIRON
• WIRON is typically 0.20–0.40pp lower than WIBOR for equivalent tenors
• The transition may slightly reduce your mortgage costs
• Banks will adjust margins to compensate, so the net effect may be modest

FAQ

Will Polish interest rates fall in 2026?

The RPP already delivered a 25bp cut in March 2026 (to 3.75%) and has paused since; markets don't expect a further cut before 2027, though the path depends on inflation. The RPP emphasizes that decisions are made "meeting by meeting" with no predetermined course.

How does the reference rate affect my mortgage?

The NBP reference rate influences WIBOR, which forms the base of most Polish mortgage rates. With a typical 2% margin, a 1 percentage point drop in the reference rate reduces payments on a 300,000 PLN mortgage by about 170–200 PLN per month.

Are Polish savings deposits worth it right now?

At roughly 3.5–4.5% nominally, deposits barely keep pace with inflation. The real return (after subtracting inflation and the 19% Belka tax) is around zero or slightly negative. For long-term savings, inflation-indexed EDO Treasury bonds are designed to keep returns above CPI.

What is the RPP and how often does it meet?

The Monetary Policy Council (Rada Polityki Pieniężnej, RPP) is the NBP body that sets interest rates. It meets monthly (except August) and decides by majority vote. It has 10 members: the NBP President and 9 members appointed by the Sejm, Senate, and President.

How can I track interest rate changes?

RPP decisions are announced after each meeting on the NBP website. WIBOR is updated daily. In Freenance, you can monitor how rate changes affect your Financial Freedom Runway in real time.
