German government bonds, known as Bunds, are long-term debt securities issued by the Federal Republic of Germany, denominated in euros and backed by the government’s full taxing authority. They carry Germany’s AAA credit rating from S&P Global and serve as the risk-free benchmark for the entire eurozone.1S&P Global. Germany AAA/A-1+ Ratings Affirmed; Outlook Stable For a US-based investor, the important thing to know upfront is that you generally cannot buy Bunds directly from the German Finance Agency; the practical route is through US-listed exchange-traded funds that hold European sovereign debt.
How Bunds Work
The German Finance Agency (Finanzagentur) issues and manages all federal securities on behalf of the government. Bunds pay a fixed coupon once per year and return 100% of face value at maturity, so the cash flow is predictable from the day of purchase.2Deutsche Finanzagentur. Federal Bonds The German government is liable for repayment with both its assets and tax revenues, and all federal securities carry a “gilt-edged” designation reflecting that safety profile.
On the secondary market, Bunds trade on any European exchange trading day through banks or brokerages with a securities custody account. Trades currently settle on a T+2 basis, with the EU working toward T+1 by late 2027.3European Securities and Markets Authority. Shortening the Settlement Cycle to T+1 in the EU As of mid-March 2026, the 10-year Bund was yielding roughly 2.97%.
Maturities and Related Federal Securities
Bunds occupy the long end of the German yield curve. The Finance Agency currently issues them with original maturities of 7, 10, 15, 20, and 30 years.4Deutsche Finanzagentur. Overview Federal Securities Shorter German federal debt goes by different names and technically isn’t a Bund: the two-year Federal Treasury Note (Schatz) and the five-year Federal Note (Bobl) cover the front and middle of the curve, and 12-month Treasury Discount Paper (Bubills) sits in the money market with a €1 million minimum aimed at institutions.5Deutsche Finanzagentur. Issuance Terms and Conditions for Federal Bonds, Five-Year Federal Notes, Federal Treasury Notes and Treasury Discount Paper If a fund advertises exposure to “German government bonds,” it may hold any of these.
Why the 10-Year Bund Yield Matters
The 10-year Bund yield functions as the risk-free rate for the eurozone in the same way the 10-year Treasury does for dollar markets. Analysts quote “spreads” on Italian, Spanish, or French sovereign debt as the yield gap over the equivalent Bund; a widening spread signals investors see more credit risk in the other issuer relative to Germany.1S&P Global.

How US Investors Access Bunds
This is where American investors get tripped up. The Finance Agency’s own website requires users to confirm they are not a US person, as defined under Regulation S of the U.S. Securities Act of 1933, before accessing securities information, and it explicitly bars distribution of its materials to US persons.2Deutsche Finanzagentur. Federal Bonds The restriction comes from US securities rules, not German law, but the effect is the same: direct purchase from the issuer is off the table for retail US buyers.
The workable path is a US-listed ETF that holds European sovereign debt, including Bunds. These funds trade on US exchanges in dollars and give you diversified exposure across maturities and often across countries. Some are currency-hedged, using forward contracts to strip out euro-dollar movement, with the hedging cost built into the expense ratio. Others leave the currency exposure open. Large US brokerages with global institutional desks may arrange individual Bund purchases through European affiliates, but the minimums and complexity put that route out of reach for most retail investors.
Currency Risk in Dollar Terms
Because Bunds are euro-denominated, an unhedged US investor takes on exchange-rate risk on top of interest-rate risk. Dollars convert to euros to buy in, coupons arrive in euros, and principal comes back in euros at maturity. If the euro weakens against the dollar over the holding period, dollar returns shrink or turn negative even if the bond itself performed exactly as promised. A strengthening euro works the other way.
Uncovered interest parity holds that interest-rate differentials should, in theory, offset expected currency moves over long horizons.7Federal Reserve Economic Data. The Link Between Interest Rates and Exchange Rates In practice, that relationship is unreliable over the periods most investors care about, and currency moves can easily overwhelm the coupon income on a 10-year bond. A currency-hedged ETF is the simplest way for a retail investor to remove that variable. Skipping the hedge on a small allocation or a multi-decade horizon is defensible, but it’s a bet on the euro, not a neutral position.
Tax and Reporting Obligations for US Holders
US taxpayers who hold Bunds, whether directly or through a foreign account, face obligations that don’t apply to Treasury bonds.
Withholding and the US-Germany Treaty
Germany generally imposes a 25% flat tax on interest income plus a 5.5% solidarity surcharge, an effective 26.375% at the source. The US-Germany tax treaty reduces the withholding rate on interest to 0% for US residents, so interest should flow through gross of German tax, provided the proper treaty forms are on file with the paying agent. The income remains fully taxable in the US as ordinary income.
FBAR
If Bunds sit in a foreign financial account, such as a European brokerage account, and the aggregate value of all your foreign accounts exceeds $10,000 at any point during the year, you must file an FBAR (FinCEN Form 114) with the Financial Crimes Enforcement Network.8Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The obligation turns on the account balance, not on whether the account produced income.
Form 8938
IRS Form 8938 covers specified foreign financial assets, including foreign securities, above certain thresholds. For unmarried filers living in the US, the trigger is $50,000 on the last day of the tax year or $75,000 at any point during the year. Joint filers in the US face $100,000 and $150,000. Filers living abroad get higher thresholds: $200,000/$300,000 single and $400,000/$600,000 joint.9Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets FBAR and Form 8938 are separate filings even though the information overlaps, and penalties for missing either are steep.
Holding Bunds indirectly through a US-listed ETF sidesteps FBAR and Form 8938 in the ordinary case, because the fund itself is a US security held in a US account. That simplification is a real part of why the ETF route is the standard answer for American investors.
Green and Inflation-Linked Variants
Two specialized Bund types show up in eurozone bond portfolios and are worth recognizing if you see them in a fund’s holdings.
Green Federal Securities use a “twin bond” structure: each green Bund is matched to an existing conventional Bund with the same coupon and maturity but its own ISIN. The Finance Agency supports the green twin’s liquidity through daily secondary-market operations and switch transactions between the two.10Deutsche Finanzagentur. Twin Bond Concept The price gap between the two versions gives the market a live read on the “greenium” investors will accept for environmentally earmarked debt.
Inflation-linked Federal Securities adjust both coupon payments and redemption value to the unrevised Harmonised Index of Consumer Prices for the euro area, excluding tobacco, calculated monthly by Eurostat.11Deutsche Finanzagentur. Inflation-linked Federal Securities They track eurozone inflation, not US inflation, so they don’t hedge the price index a US investor actually lives with.
