FX.co ★ Spanish 3-Month Letras Auction Yield Rises to 2.635%

The yield on Spain’s 3-month government Letras climbed at the latest auction, with the indicator rising to 2.635% from the previous 2.456%. The move reflects a noticeable uptick in short-term borrowing costs for the Spanish Treasury.

The updated figures, published on 13 October 2026, suggest investors are now demanding a higher return for holding Spain’s very short-dated debt. While no additional details on demand or auction volume were provided, the increase in the yield may signal shifting expectations around euro area interest rates or short-term funding conditions in Spain’s sovereign debt market.
