Treasury bonds are debt securities issued by the State Treasury. By buying a bond, you lend money to the state, and in return you receive interest. This is one of the safest forms of investment — the state budget is the guarantor.

TOZ — 3-year (variable rate)
- Interest rate: WIBOR 6M + margin

COI — 4-year (inflation-indexed)
- Interest rate: inflation + margin (e.g., 1.25%)
- Period: 4 years

Which Bond to Choose?
Goal: emergency fund (0–6 months)
Choose: OTS (3-month)
Quick access to money. Low interest rate, but better than on current account. Remember that early redemption involves a fee.
Goal: saving for specific expense (1–3 years)
Choose: DOS (2-year) or TOZ (3-year)
Fixed interest rate of DOS provides predictability. TOZ is better when interest rates are rising.
Goal: inflation protection (3–10 years)
Choose: COI (4-year) or EDO (10-year)
These are the most popular bonds among conscious investors. EDO offers higher margin above inflation, but requires longer horizon. COI is a compromise between protection and flexibility.
Goal: building retirement portfolio
Choose: EDO (10-year)
Long horizon + inflation protection = ideal safe part of retirement portfolio. Combine with stock ETFs.

Early Redemption — How Much Does It Cost?
You can redeem bonds before maturity, but this involves a fee:
| Bond | Early redemption fee |
|---|---|
| OTS | PLN 0.50/piece |
| DOS | PLN 0.70/piece |
| COI | PLN 0.70/piece |
| EDO | PLN 2.00/piece |
The fee is deducted from accrued interest.
Bonds and Taxes
- Interest is subject to capital gains tax (19%)
- Tax is automatically deducted upon redemption
- Bonds are not available on IKE/IKZE accounts (but consider bond ETFs within these accounts)
Ladder Strategy
Instead of putting everything into one issue, spread purchases over time:
- Month 1: buy EDO for PLN 2,000
- Month 2: buy COI for PLN 2,000
- Month 3: buy EDO for PLN 2,000
- And so on...
This way every few months another series matures, giving you regular access to part of your capital.
