How to analyze a bond fund — key indicators
1. TER (Total Expense Ratio) — total costs
TER is the annual fund management costs expressed as percentage of asset value.
Cost benchmarks:
- Treasury funds: 0.5-1.0% = good level
- Corporate funds: 0.8-1.3% = acceptable
- Foreign funds: 1.0-1.5% = normal level
- Above 1.5% = high costs, avoid
Example of cost impact:
Fund A: 5.5% return, 0.8% TER = 4.7% net return
Fund B: 5.5% return, 1.5% TER = 4.0% net return
Difference: 0.7% annually = 3,500 PLN on 50k capital in 10 years!
2. Duration — interest rate sensitivity
Duration tells you by what percentage the fund value will drop when interest rates rise by 1%.
Interpretation:
- Duration 1-2 years: low interest rate risk
- Duration 3-5 years: moderate risk
- Duration 5+ years: high interest rate risk
Example: Fund has 4-year duration. If NBP raises rates by 1%, fund value will drop by ~4%.
3. Yield to Maturity (YTM) — expected profitability
YTM is the expected annual return rate if bonds are held to maturity.
Current YTM levels (2026):
- Polish treasury bonds: 5.0-6.5%
- Investment grade corporate bonds: 5.5-7.0%
- High-yield bonds: 7.0-10.0%
4. Credit Quality
Bond ratings in portfolio show credit risk level:
Rating scale:
- AAA to BBB-: investment grade (safe)
- BB+ and lower: high yield (risky)
- No rating: often most risky

Bond portfolio building strategy
Conservative portfolio (100% bonds):
- 40% treasury bond fund (stable foundation)
- 30% corporate bond fund (higher interest rates)
- 20% foreign bond fund (diversification)
- 10% high-yield fund (return kicker)
Expected return: 5.5-6.5% annually
Volatility: 3-5%
Maximum drawdown: -8% to -12%
Balanced portfolio (60% bonds + 40% stocks):
- 30% treasury bond fund
- 30% corporate bond fund
- 25% equity ETF (IWDA or similar)
- 15% Polish stocks (WIG20 ETF)
Expected return: 7-9% annually
Volatility: 8-12%
Maximum drawdown: -15% to -25%
Taxes on bond funds
Bond funds are subject to 19% Belka tax:
When you pay tax:
- Upon withdrawal (sale of units) with profit
- On interest income — tax withheld at source monthly
Tax optimization:
- Accumulating funds (reinvesting interest) defer tax
- IKE/IKZE — consider bonds within retirement accounts
- Loss offset — losses can be deducted from gains
Calculation example:
Investment: 50,000 PLN in bond fund
Return: 5.8% annually = 2,900 PLN profit
Tax: 2,900 × 19% = 551 PLN
Net profit: 2,349 PLN (4.7% effectively)
Bond fund risks — what to avoid
1. Interest rate risk
What it is: bond values fall when interest rates rise
How to limit: choose funds with low duration
2. Credit risk
What it is: issuer may not repay bond
How to limit: invest in funds with high ratings (BBB+ and above)
3. Liquidity risk
What it is: difficulty selling bonds in tough times
How to limit: choose large, reputable funds
4. Currency risk
What it is: losses when foreign currency exchange rate falls
How to limit: funds with currency hedging
Mistakes when choosing bond funds
❌ Focus only on past returns
Past performance doesn't guarantee future results. Costs, duration, credit quality are more important.
❌ Ignoring costs
0.5% difference annually means thousands of PLN in long term.
❌ Lack of diversification
Don't put everything in one bond type. Mix treasury + corporate + foreign.
❌ Forgetting about inflation
If fund gives 5% and inflation is 4%, real return is only 1%!
❌ Panic during rate changes
When interest rates fall, bond values rise. This is normal.
Monitoring and rebalancing
Check monthly:
- Bond portfolio value
- Paid interest and reinvestments
- Changes in fund composition (if available)
Analyze quarterly:
- Results vs benchmark (bond index)
- Changes in duration and risk profile
- Actual costs vs announced TER
Rebalancing (every 6-12 months): If allocation deviates from plan by >5%, restore proportions:
Example:
Plan: 40% treasury + 40% corporate + 20% foreign
Reality: 35% + 45% + 20%
Action: Sell some corporate, buy treasury
Summary: Bond fund as portfolio foundation
Bond funds are an essential element of every long-term investment portfolio. In 2026, with attractive 5-7% interest rates, bonds offer a real alternative to bank deposits with acceptable risk levels.
Key principles for choosing bond funds:
