Government Bonds vs Stocks: How to Choose Between Safety and Growth
Comparison of government bonds and stocks for European investors. Historical returns, risk profiles, and how to balance both in your portfolio.
Government Bonds vs Stocks: How to Choose Between Safety and Growth
The stock-bond decision is the most consequential choice in investing. Over the last century, global stocks have returned approximately 7-8% real (after inflation) annually, while government bonds have returned 1-3% real. That gap translates into dramatically different outcomes: 10,000 EUR invested in stocks for 30 years at 7% real grows to roughly 76,000 EUR. The same amount in bonds at 2% real grows to 18,000 EUR.
So why would anyone hold bonds? Because returns are only half the story. The other half is risk, and bonds reduce portfolio risk in ways that change what you can actually stick with through market crashes.
Understanding the basic difference
Stocks (equities)
When you buy a stock or stock ETF, you own a piece of businesses. Your return comes from two sources: the businesses growing (stock price appreciation) and businesses distributing profits (dividends).
The catch: Business values fluctuate. A lot. The MSCI World Index has experienced peak-to-trough declines of:
- -57% during 2007-2009 (Global Financial Crisis)
- -34% in March 2020 (COVID crash)
- -20% in 2022 (interest rate shock)
Recover times range from months (2020) to years (2007-2013). During these drawdowns, you see your portfolio's value fall by a third or more on paper.
Government bonds
When you buy a government bond, you lend money to a government. Your return comes from interest payments (coupon) and the return of principal at maturity.
The appeal: High certainty of repayment (for investment-grade sovereigns). Known cash flows. Lower volatility than stocks.
The catch: Lower returns. Vulnerable to inflation (a bond paying 3% in a 5% inflation environment loses purchasing power). Interest rate risk (existing bond values fall when new bonds offer higher rates).
Historical returns
Global data (1900-2025, real returns after inflation)
| Asset class | Annualised real return | Worst single year | Best single year |
|---|---|---|---|
| Global stocks | ~7.5% | -40% (2008) | +55% (1933) |
| Global government bonds | ~1.5% | -30% (2022) | +30% (1982) |
| Cash/T-Bills | ~0.5% | -15% (high inflation years) | +10% |
Polish context (2000-2025)
| Asset class | Annualised return (PLN, nominal) |
|---|---|
| WIG (Polish stocks) | ~8% |
| Polish Treasury bonds (EDO, 4-year) | ~5% |
| Polish savings deposits | ~3% |
| Polish CPI inflation | ~3.5% |
Polish Treasury bonds have performed reasonably well due to Poland's higher interest rate environment compared to the eurozone. EDO bonds (4-year, inflation-linked) have been particularly attractive, offering CPI + 1% after the first year.
When bonds outperform stocks
Bonds tend to win in three scenarios:
1. Deflationary recessions
When the economy contracts and inflation falls, central banks cut rates. Existing bonds with higher coupon rates increase in value. Meanwhile, stocks fall as corporate earnings decline. This pattern played out in 2008-2009.
2. Short time horizons
Over 1-5 year periods, stocks are highly unpredictable. You have roughly a 30% chance of losing money in stocks over any given year. Over any given 5-year period, the odds drop to about 15%. But bonds provide much more predictable returns over short periods (assuming you hold to maturity or buy short-duration bonds).
3. Extreme stock valuations
When stocks are extremely expensive (high P/E ratios, low dividend yields), their expected future returns are lower and their downside risk is higher. Bonds become relatively more attractive. This does not mean you can reliably time the market, but it does mean the relative attractiveness shifts.
When stocks dominate
Long time horizons (10+ years)
Over any 15-year period in market history, stocks have outperformed bonds the vast majority of the time. Over 20+ years, stocks have always won. The power of compounding equity returns overwhelms bond returns over long periods.
Inflationary environments
Stocks represent ownership in real businesses that can raise prices with inflation. Bonds are nominal contracts: a 3% coupon on a bond is worth less when inflation is 5%. The 2021-2023 inflationary period destroyed bond values (-20% to -30%) while stocks recovered relatively quickly.
Wealth building phase
If you are 25-45 and accumulating wealth for retirement, bonds drag down your long-term returns. A 100% stock portfolio at age 25 has a higher expected terminal value than any stock/bond mix over a 30-40 year horizon.
The role of bonds in a portfolio
Bonds serve three practical functions:
1. Reducing portfolio volatility
A 70/30 stock/bond portfolio has historically experienced maximum drawdowns of approximately 30-35%, compared to 50-55% for a 100% stock portfolio. If the difference between a 35% and 55% paper loss determines whether you panic-sell, bonds are worth their return drag.
2. Providing rebalancing fuel
When stocks crash, you sell bonds (which have held value or risen) and buy stocks at lower prices. When stocks rally, you sell some stocks and buy bonds. This systematic rebalancing adds approximately 0.3-0.5% per year in risk-adjusted return over long periods.
3. Funding near-term needs
Money you need within 1-5 years should not be in stocks. Bonds or bond ETFs with maturity matching your time horizon provide predictable returns for near-term goals (down payment, tuition, large purchase).
Polish Treasury bonds: a special case
Polish retail Treasury bonds (obligacje skarbowe) offer unique advantages:
| Bond type | Term | Rate (2026) | Inflation protection |
|---|---|---|---|
| OTS (3-month) | 3 months | ~5.0% | No |
| DOS (2-year) | 2 years | ~5.25% | No |
| TOZ (3-year) | 3 years | Variable (WIBOR6M) | Partial |
| COI (4-year) | 4 years | CPI + 1% (yr 2-4) | Yes |
| EDO (10-year) | 10 years | CPI + 1.25% (yr 2-10) | Yes |
| ROS (6-year family) | 6 years | CPI + 1.5% | Yes |
| ROD (12-year family) | 12 years | CPI + 2% | Yes |
Key advantage: When held in IKE, Polish Treasury bonds are tax-free. A COI bond yielding CPI + 1% (effectively ~5% in 2026) with no tax and no default risk is a compelling fixed-income option that has no equivalent in the ETF market for PLN-based investors.
Key disadvantage: Early redemption incurs a penalty (typically loss of the last year's interest for COI/EDO). Bond ETFs can be sold instantly at market price.
Practical allocation
For a Polish investor building a long-term portfolio:
- IKE: Stocks (VWCE/IWDA) for growth, plus Polish Treasury bonds (COI/EDO) for the bond allocation. Both tax-free.
- IKZE: Stocks only (shorter to retirement horizon maximises the tax deduction benefit).
- Taxable account: Stocks (VWCE) for growth. If you need bonds in the taxable account, AGGH (iShares Global Aggregate Bond ETF) is the simplest option, though taxed at 19%.
