The figures displayed in the calendar represent the average yield on the Bons du Trésor à taux fixe or BTF auctioned.
French BTF bills have maturities of up to 1 year. Governments issue treasuries to borrow money to cover the gap between the amount they receive in taxes and the amount they spend to refinance existing debt and/or to raise capital.
The yield on the BTF represents the return an investor will receive by holding the treasury for its entire duration. All bidders receive the same rate at the highest accepted bid.
Yield fluctuations should be monitored closely as an indicator of the government debt situation. Investors compare the average rate at auction to the rate at previous auctions of the same security.
