Complete Guide to Government Bonds in Europe
Everything you need to know about Government Bonds, including how they work, what to consider, and country-specific details.
Last updated: June 2026
What Are Government Bonds?
Government bonds are debt securities issued by national treasuries to finance public spending. Eurozone sovereign bonds are considered among the safest investments available, with German Bunds being the benchmark for risk-free rates. Shorter-term instruments (treasury bills or Letras) are typically zero-coupon and sold at a discount, while longer-term bonds pay periodic coupons. Yields vary by country based on perceived credit risk — southern European issuers (Spain, Italy, Portugal) generally offer higher yields than core countries (Germany, Netherlands).
How Government Bonds Work
You can purchase government bonds at primary auctions (directly from the treasury) or on the secondary market through a broker. Treasury bills (maturity under 1 year) are sold at a discount to face value — for example, a €1,000 bill might be sold for €978, and you receive €1,000 at maturity. Longer-term bonds pay fixed semi-annual or annual coupons. Bond prices on the secondary market fluctuate inversely with interest rates: when rates rise, existing bond prices fall, and vice versa.
Key Considerations for European Investors
- Sovereign bonds carry credit risk — yields differ significantly between AAA-rated (Germany) and lower-rated issuers (Italy)
- Selling before maturity exposes you to price risk if interest rates have changed
- Treasury bills (short-term) have minimal price risk and are effectively equivalent to term deposits
- Some countries offer favorable tax treatment for domestic government bonds (e.g. Italy taxes at 12.5% instead of 26%)
- Certificados de Aforro (Portugal) are unique retail instruments indexed to Euribor 3M with loyalty premiums
Government Bonds by Country
Compare Government Bonds across different European countries to find the best option for your tax residence:
SpainTax: 19% · Inflation: 3.6%
Letras del Tesoro (Spanish Treasury bills) can be purchased directly through the Banco de España website with no fees. They are zero-coupon instruments with 3, 6, 9, and 12-month maturities. Interest from Spanish government bonds is taxed at the standard 19%–28% capital gains rates. Spain's 10-year bond yield typically trades 70–90 basis points above Germany.
Government Bonds in Spain →PortugalTax: 28% · Inflation: 3.1%
Certificados de Aforro are Portugal's flagship retail savings product, available exclusively to residents. Series F is indexed to 3-month Euribor with loyalty premiums that increase over time (up to +1.50% after year 5). They are purchased through CTT (Portuguese postal service) and protected by the Portuguese state. Standard government bonds (OTs) are taxed at the standard 28% rate.
Government Bonds in Portugal →GermanyTax: 26% · Inflation: 2.4%
German Bunds are the eurozone's benchmark safe-haven asset. They carry a AAA rating and typically offer the lowest yields in the eurozone. Schatzanweisungen (2-year treasury notes) and Bubills (short-term discount papers) are available for shorter maturities. Bond interest is taxed at the flat 26.375% rate after the Sparerpauschbetrag allowance.
Government Bonds in Germany →FranceTax: 31% · Inflation: 2.0%
French government bonds (OATs) carry an AA rating and typically yield slightly above German Bunds. BTFs (Bons du Trésor) are short-term discount instruments akin to German Bubills. Bond income is taxed at the 30% PFU. France also offers OATi (inflation-linked bonds) for investors seeking explicit inflation protection.
Government Bonds in France →ItalyTax: 26% · Inflation: 3.1%
Italian government bonds (BTPs and BOTs) enjoy a favorable 12.5% tax rate instead of the standard 26% — a significant advantage. Italy offers a wide range of instruments: BOTs (short-term bills), CTZ (zero-coupon medium-term), BTP (fixed-rate), and BTP Italia (inflation-linked). Italian 10-year yields typically trade 100–150 basis points above German Bunds, reflecting the higher credit premium.
Government Bonds in Italy →NetherlandsTax: 24% · Inflation: 2.5%
Dutch government bonds (DSLs) carry a AAA rating and yield close to German Bunds, as both are considered core eurozone safe havens. Bond holdings are taxed under Box 3 on their market value, not on actual interest income. Dutch State Treasury Agency (DSTA) manages issuance of DSLs in various maturities.
Government Bonds in Netherlands →BelgiumTax: 30% · Inflation: 3.0%
Belgian government bonds (OLOs — Obligations Linéaires / Lineaire Obligaties) carry an AA rating. Belgium periodically issues retail-targeted instruments like the Staatsbon / Bon d'État, which are accessible directly through Belgian banks. Bond interest is taxed at 30%, though the 2023 one-year Staatsbon at 3.30% attracted massive retail interest. Belgian government bond yields typically sit between German and French levels.
Government Bonds in Belgium →AustriaTax: 28% · Inflation: 3.1%
Austrian government bonds (Bundesanleihen) carry an AA+ rating and yield slightly above German Bunds. The Österreichische Bundesfinanzierungsagentur (OeBFA) manages issuance. Bond interest is taxed at 27.5% KESt. Austria also issues Bundesschatzscheine (treasury bills) for shorter maturities. Austrian government bonds are considered very safe within the eurozone.
Government Bonds in Austria →IrelandTax: 33% · Inflation: 3.2%
Irish government bonds carry an A+ rating and yield slightly above core eurozone countries. Bond interest and capital gains are taxed at 33% CGT. Ireland does not offer a retail-specific government bond program like Portugal's Certificados de Aforro or Belgium's Staatsbon. Irish government bonds can be purchased through brokers on the secondary market.
Government Bonds in Ireland →Frequently Asked Questions
How do I buy government bonds?
There are two main ways: (1) Primary market — subscribe during treasury auctions directly through the national debt agency or your bank. This is often fee-free. (2) Secondary market — buy already-issued bonds through a stockbroker, where prices fluctuate based on supply, demand, and interest rates.
What is the difference between a treasury bill and a government bond?
Treasury bills (T-bills) are short-term instruments (typically 3–12 months) sold at a discount with no coupon payments. Government bonds have longer maturities (2–30 years) and pay periodic coupon interest. T-bills have virtually zero price risk if held to maturity, while longer bonds are more sensitive to interest rate changes.
Do eurozone government bonds have credit risk?
Yes, though it varies. German Bunds (AAA) are considered virtually risk-free. Italian BTPs (BBB) carry higher credit risk, reflected in their yield premium of 100–150 basis points over Bunds. Portugal, Spain, and France fall in between. For short-term instruments (under 1 year), credit risk is minimal even for lower-rated issuers.
