Bond investment strategies
Strategy 1: Bond ladder
Principle: You buy bonds with different maturity dates
Example with 50,000 PLN:
- 10,000 PLN — OTS (3 months)
- 15,000 PLN — ROR (12 months)
- 25,000 PLN — COI (4 years)
Effect:
- Regular income from redemptions
- Reinvestment at current rates
- Protection against interest rate risk
Strategy 2: Barbell
Principle: Part of money in short, part in long bonds
Example:
- 60% — OTS and TOZ (liquidity)
- 40% — COI and EDO (higher profitability)
Strategy 3: All-in long-term
For whom: Investors focused on long period
Recommendation:
- 80% COI (inflation protection)
- 20% EDO (additional premium for length)

When to choose Treasury bonds?
Bonds ARE a good choice when:
1. You need safety
- Savings for apartment (1-2 years)
- Emergency fund
- Retirement capital (near future)
2. Interest rates are high
- NBP raises rates (2022-2025)
- Real rates positive (above inflation)
- Yield gap vs bank deposits > 1 p.p.
3. You have short investment horizon
- Up to 2 years — better than stocks
- 2-5 years — comparable to stocks with less risk
Bonds are BAD choice when:
1. Long-term horizon (10+ years)
- Stocks/ETFs historically give higher returns
- Inflation long-term "eats" fixed interest
2. Interest rates falling
- Fixed-rate bonds lose attractiveness
- Better to wait for higher rates
3. Very high inflation
- Even COI may not keep up with sudden price jumps
- Real rates negative
Treasury bond limits
Annual limits (2026):
| Bond type | Limit per person | Limit per family |

Common bond mistakes
1. Buying only short-term
Problem: Missing higher rates when NBP cuts Solution: Maturity diversification (ladder)
2. Ignoring inflation
Problem: Fixed interest vs rising prices Solution: Mix COI + fixed-rate bonds
3. Early redemption without need
Problem: Loss of part of interest (penalty interest) Solution: Cash flow planning
4. Exceeding limits
Problem: Excess returns to account, no interest
Solution: Monitoring limits in app
