Polish Treasury Bonds as a Source of Passive Income

Polish Treasury Bonds as a Source of Passive Income

Polish treasury bonds (obligacje skarbowe) are among the safest financial instruments available in Poland. Backed by the State Treasury, accessible from just 100 PLN, and offering predictable returns, they make an ideal foundation for any passive-income portfolio. Here is how to put them to work in 2026.

Types of Polish Treasury Bonds

The Ministry of Finance offers several types of retail bonds, each with different characteristics:

3-Month Bonds (OTS)

• Fixed interest rate, currently around 3-3.5%
• Great for short-term cash parking
• Interest paid after 3 months

1-Year Bonds (ROR)

• Variable rate tied to the NBP reference rate
• Interest paid monthly
• Attractive when interest rates are high

3-Year Bonds (TOS)

• Fixed rate in the first year, then variable
• Interest paid every 6 months

4-Year Inflation-Indexed Bonds (COI)

• The most popular choice for passive income
• Interest rate = CPI inflation + a margin (currently 1-1.25%)
• Interest paid annually
• Built-in inflation protection

10-Year Inflation-Indexed Bonds (EDO)

• Interest rate = CPI inflation + a margin (currently 1.5-1.75%)
• Interest is capitalised (added to principal)
• Highest margin, but longest time horizon

How Much Can You Earn from Treasury Bonds?

Assume CPI inflation of 4% and calculate the income from COI bonds with a 1.25% margin:

Gross interest rate: 4% + 1.25% = 5.25% Net rate (after 19% Belka tax): 4.25%

If inflation rises to 5% with the same 1.25% margin, income scales proportionally -- that is the beauty of inflation indexation.

Why Bonds Make a Solid Base for a Passive Portfolio

Safety

Treasury bonds are guaranteed by the Polish State Treasury. This represents the lowest possible credit risk in the domestic currency.

Inflation Protection

COI and EDO bonds automatically adjust their interest rates to inflation. Unlike bank deposits, your real income does not erode over time.

Predictability

You know exactly how much you will earn (within the range of inflation outcomes). There are no stock-market or property-market surprises.

Accessibility

You can buy bonds online at obligacjeskarbowe.pl or at a PKO BP branch. The minimum investment is just 100 PLN.

The Bond Ladder Strategy

One of the most effective approaches is a bond ladder -- spreading capital across bonds with different maturities:

Example with 400,000 PLN:

• 100,000 PLN in 1-year ROR bonds
• 100,000 PLN in 3-year TOS bonds
• 100,000 PLN in 4-year COI bonds
• 100,000 PLN in 10-year EDO bonds

This strategy delivers:

• Regular interest payments (monthly, semi-annually, annually)
• Flexibility -- part of the capital is accessible in the short term
• Rate optimisation -- longer bonds carry a higher margin

Treasury Bonds Inside IKE and IKZE

You can purchase treasury bonds within IKE and IKZE retirement accounts, unlocking additional tax benefits:

• IKE -- no capital-gains tax on withdrawal after age 60
• IKZE -- contributions are tax-deductible, and the exit tax is only 10%

With COI bonds held inside an IKE, the full 5.25% interest rate reaches you free of the Belka tax. On 100,000 PLN of capital, that is the difference between receiving 4,250 PLN and 5,250 PLN per year.

Drawbacks of Treasury Bonds

• Early redemption -- possible, but you lose part of the accrued interest (a fee of 0.50-2 PLN per bond)
• Low liquidity -- retail bonds cannot be sold on the secondary market
• Limited upside -- you will never earn more than inflation plus the margin
• Downside inflation risk -- if inflation falls very low, income shrinks

How to Buy Polish Treasury Bonds

1. Create an account at obligacjeskarbowe.pl
2. Verify your identity (can be done online)
3. Transfer funds to your purchase account
4. Select the bond type and quantity
5. Confirm the purchase

The entire process takes 15-30 minutes for a first-time buyer.

Treasury Bonds in the Context of Financial Freedom

Treasury bonds are an excellent foundation for an income portfolio, yet they are unlikely to be sufficient as the sole source of passive income -- unless you have a very large amount of capital.

They work best when combined with other assets: dividends, ETFs, and possibly real estate. Using Freenance, you can track how your bond portfolio (and other assets) affects your financial-freedom runway -- the number of months you could live without working.

Summary

Polish treasury bonds offer a safe, predictable, and accessible form of passive income. Inflation-indexed bonds (COI and EDO) in particular are powerful tools for protecting capital and generating real returns. Use them as the base of your portfolio, and over time layer in higher-yielding -- but higher-risk -- assets on top.

FAQ

Which Polish treasury bond offers the best protection against inflation?

The 10-year EDO bonds offer the highest margin above CPI inflation (currently 1.5-1.75%) and capitalise interest into principal, making them the strongest inflation hedge over long horizons. The 4-year COI bonds provide similar inflation indexation with a shorter commitment and annual cash interest payments.

Can I sell Polish retail treasury bonds before maturity?

You can request early redemption directly from the issuer, but a small fee per bond is deducted (typically 0.50-2 PLN). Retail treasury bonds cannot be sold on a secondary market, so liquidity is limited compared to exchange-traded bonds.

Are treasury bonds a good fit for IKE or IKZE accounts?

Yes, and the combination is particularly powerful. Holding inflation-indexed bonds inside an IKE eliminates the 19% Belka tax on interest, effectively boosting your net yield by about one full percentage point on COI bonds.

How does the bond ladder strategy work?

A bond ladder spreads capital across bonds with staggered maturities (e.g. 1-year, 3-year, 4-year, and 10-year tranches). This produces a steady stream of interest payments, maintains short-term access to part of your capital, and captures the higher margins available on longer-dated series.

What is the minimum investment in Polish treasury bonds?

The minimum is just 100 PLN per bond, making them one of the most accessible investments available to Polish residents. You can open an account online and complete the entire purchase process in 15-30 minutes.
