Definition — Yield at which the market lends to the State, by borrowing horizon: 1-, 5- and 10-year government bonds, daily quotes from the national central bank, with the euro-area overnight rate (€STR, ECB) as a reference. The lower it is, the cheaper the debt is to finance.

• Germany — Bundesbank term structure: zero-coupon yield at 1, 5 or 10 years residual maturity, estimated daily (Svensson method) from the prices of listed Federal securities (Bund, Bobl, Schatz). It is what Federal borrowing at that horizon costs at the day's conditions.
• 1 day: €STR, the rate at which euro-area banks borrow unsecured overnight (ECB). Not a State borrowing rate, but the benchmark for very short rates.
• 1 week, 1 month, 3 and 6 months: not shown. The Bundesbank daily curve starts at 1 year residual maturity; issue yields of the Federal short-term paper (Bubills) are not released as an open daily series.
• Weekly, monthly, annual: average of the period's daily quotes; the running period is dashed and is never the value shown.
