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

Quick Answer

The NBP (National Bank of Poland) reference rate stands at 5.75% as of March 2026 — unchanged since October 2023. This keeps mortgage costs high (WIBOR 3M hovers around 5.80%), but savings accounts and government bonds offer decent nominal returns. The Monetary Policy Council (RPP) signals potential cuts in the second half of 2026, but everything depends on inflation's trajectory.

Current NBP Interest Rates (March 2026)

These rates have been in effect since October 4, 2023 — over two years without a change. It's the longest hold period since the 2021–2023 hiking cycle ended.

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 5.80% and a typical margin of 2.0%, total mortgage interest is about 7.80%. For a 300,000 PLN mortgage (25 years), that's roughly 2,280 PLN/month (€530).

If the reference rate dropped to 4.00% (WIBOR ~4.10%), the same payment would be about 1,930 PLN — a saving of 350 PLN/month (€80) or 4,200 PLN/year (€975).

Savings Accounts & Deposits

High rates are good news for savers — at least nominally. Top deposit rates in March 2026:

• 3-month deposits: 5.0–5.5%
• 6-month deposits: 5.2–5.8%
• 12-month deposits: 5.0–5.5%

But watch the real return. With CPI inflation at ~4.5%, a 5.5% deposit yields just 1.0% in real terms — and after the 19% Belka tax on interest income, you're essentially at zero.

Government Bonds

Polish Treasury bonds indexed to inflation (EDO, COI) are particularly attractive:

• EDO (4-year): 1.00% margin + CPI inflation → ~1% real annual return
• COI (3-year): 0.50% margin + CPI inflation
• TOS (3-month): fixed rate linked to the reference rate

EDO bonds remain one of the best vehicles for long-term savings in Poland, guaranteeing returns above inflation.

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 ~4.5% 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 (March 2026): A first 25bp cut is possible in Q3–Q4 2026, but not before July. Markets price the reference rate at 5.00–5.25% by year-end.

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 5.5% and inflation is 4.5%, your money grows by just 1% per year 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 (4-year) are a safe long-term option — they 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?

Market consensus suggests a possible first 25bp cut in H2 2026, but it depends on the inflation path. The RPP has repeatedly emphasized 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 5.0–5.8% nominally, deposits look attractive. However, the real return (after subtracting inflation and the 19% Belka tax) is near zero. For long-term savings, consider inflation-indexed EDO Treasury bonds, which guarantee returns above inflation.

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.
