Briefing
The Tesoro Público on 6 October 2026 in Madrid a total of 6,470.6 million euros placed in an auction of short-term government securities. Demand was around 9,017 million euros, substantially exceeding the amount offered; the target range of 5,500 to 6,500 million euros was almost fully reached. The 12-month securities accounted for 4,173.5 million euros of the issuance volume, with the marginal interest rate on the 12-month Letras standing at 3.026 per cent. This means the one-year yield has risen above the 3 per cent mark for the first time since July 2024 again.
For the 6-month Letras were presented 2,297.1 million euros was raised; the marginal rate reached 2.798 per cent. Both rates therefore rose compared with the previous auction (2.846 per cent for 12 months and 2.641 per cent for six months), reaching their highest levels in each segment since the respective periods cited. Today’s results are from the official auction data published by the Tesoro Público and the market regulator.
The rise in yields reflects changing investor expectations about interest rates and increases the state’s short-term borrowing costs. At the same time, the higher coupons once again offer conservative investors more attractive returns over shorter maturities. The Tesoro’s scheduled October issuance includes further auctions: Letras with three- and nine-month maturities are planned for 13 October, followed on 15 October by issues of Bonos y Obligaciones. As usual, the final terms of these auctions will only be announced on the respective auction dates.
All figures cited in this text—volumes, interest rates and demand—are based on the auction results published today by the Tesoro Público. Comments on long-term budgetary effects or future ECB decisions are assessments by market participants and go beyond the documented facts.
