All Bond Types Available in 2026

3-Month Bonds (OTS)

• Term: 3 months
• Interest rate: ~5.75% (fixed)
• Minimum: 100 PLN
• Interest payment: at maturity

Best for: Parking cash short-term, alternative to bank deposits. Simple, predictable, but lower returns than longer bonds.

1-Year Bonds (ROR)

• Term: 12 months
• Interest rate: ~5.90% first month, then reference rate + margin
• Minimum: 100 PLN
• Interest payment: monthly

Best for: Those wanting monthly income with near-term flexibility. Rate adjusts based on NBP reference rate.

2-Year Bonds (DOR)

• Term: 2 years
• Interest rate: ~5.95% first month, then reference rate + margin
• Minimum: 100 PLN
• Interest payment: monthly

Best for: Slightly longer commitment with monthly cash flow. Good if you expect rates to stay elevated.

3-Year Bonds (TOS)

• Term: 3 years
• Interest rate: ~6.20% (fixed for first 6 months), then based on WIBOR 6M
• Minimum: 100 PLN
• Interest payment: every 6 months

• Term: 4 years
• Interest rate: ~6.55% first year, then CPI inflation + 1.00% margin

• Minimum: 100 PLN
• Interest payment: annually (capitalized)

• Eligibility: Families receiving 800+ child benefit
• ROS: 6 years, ~6.75% first year, then CPI + 1.50%

Comparison Table

How Much Will You Earn? Example with 50,000 PLN

Assuming 4% average inflation over the bond's lifetime:

• OTS (3 months): ~580 PLN net (after 19% tax)
• COI (4 years): ~10,500 PLN net
• EDO (10 years): ~33,000 PLN net (with compounding)

These are estimates — actual returns depend on future inflation and reference rates.

Treasury Bonds vs Other Options

Bonds vs Term Deposits

Deposits offer similar or slightly lower rates for 3-6 months. For 1+ year horizons, inflation-indexed bonds (COI, EDO) typically outperform deposits, especially in inflationary environments.

Bonds vs ETFs

ETFs offer higher potential returns (7-10% historically) but carry market risk. Treasury Bonds guarantee principal return. A balanced portfolio includes both.

Bonds on IKE

You can buy Treasury Bonds through an IKE account, making interest income completely tax-free. This is especially powerful for EDO 10-year bonds where compounding over a decade generates significant tax savings.

Early Redemption

You can redeem bonds early, but there's a penalty fee (0.50-2.00 PLN per 100 PLN face value). This effectively reduces your return. For short-term needs, OTS (3-month) bonds or savings accounts may be more appropriate.

Summary

The best Polish Treasury Bonds in 2026 depend on your time horizon:

• Short-term (< 1 year): OTS or ROR
• Medium-term (2-4 years): COI — inflation protection with reasonable commitment
• Long-term (10+ years): EDO — maximum inflation margin with compounding
• Families: ROD — highest margin at CPI + 1.75%

Key principles:

• Ladder your bonds — buy different types with staggered maturities
• Use IKE — tax-free interest on long-term bonds is powerful
• Don't redeem early unless necessary — penalties eat into returns
• Combine with ETFs — bonds for stability, ETFs for growth
