What Is a Bund?

Germany issues debt securities called Bunds to finance their expenditures. These securities are accepted by the European Central Bank (ECB) as collateral for credit operations. Bunds are auctioned with maturities of 7, 10, 15, and 30 years. They can also be stripped, which means that coupon payments and principal repayments can be sold separately.


Germany's federal government issues bunds, a sovereign debt instrument, to fund various expenditures. The term "bund" in German is derived from "Bundesanleihe" or "federal bond," serving as the German counterpart to U.S. Treasury bonds (T-bonds).

Exploring German Bunds

Germany's federal government issues bunds, akin to the U.S. T-bonds, to fund its expenditures. These instruments, functioning as loans to the government, undergo primary market auctions and subsequent trading in the secondary market. Bunds, a crucial financing source for the German government, generally provide annual interest and principal payments. Additionally, they can be stripped, allowing separate trading of coupon payments and principal repayments.

Historically, bunds were exclusively auctioned with original 10- and 30-year maturities until the second quarter of 2020. Notably, in May 2020, the issuance landscape expanded to include seven- and 15-year bunds for the first time.

Features of Bunds

Bunds, characterized as fixed-rate nominal bonds with fixed maturities, differ in their issuance from paper certificates as they are registered in the government debt register. An issued bund provides details such as issuance volume, maturity date, coupon rate, payable terms, and the standard for interest calculation. With the smallest denomination at €0.01, these securities can be redeemed by the German government at their par value.

Importance of Bunds in Financial Markets

Bunds, characterized by high liquidity, serve as eligible insurance reserves for trusts and are accepted by the European Central Bank as collateral for credit operations. With primary market auctions exceeding €1 billion, the German government often follows new issues with increased volumes, reaching up to approximately €15 billion to sustain robust trading activity.

Constituting approximately 50% of Germany's outstanding government debt, bunds play a pivotal role in government funding. The issuance of bunds and other long-term securities provides German authorities with a stable financing source, reducing the necessity for frequent debt rollovers. Initially a niche product, bunds gained broader market acceptance after the 2009 European sovereign debt crisis.

Bund Stripping: Enhanced Investment Opportunities

The inception of bund stripping in 1997 broadened investment choices by allowing the independent trading of principal and interest coupons. This separation enables standalone trading with a minimum amount of €50,000 and a minimum denomination of €0.01.

Credit institutions or the German Finance Agency, holding custody of the bund account, can facilitate stripping. Coupon strips are commonly bundled based on maturity profiles traded under single security identification numbers. It's important to note that strips from distinct bund types cannot be amalgamated.


Issuing Bunds is a crucial financial strategy for Germany to fund its various expenditures. These securities are accepted by the European Central Bank as collateral and play a vital role in sustaining government operations. The flexibility and adaptability of Bunds, with various maturities and the option for bund stripping, contribute significantly to the stability of Germany's financial landscape. The fact that Bunds have evolved from a niche product to a mainstream investment option underscores their enduring importance, especially during periods of economic uncertainty.
