FX.co ★ Spanish 3-Month Letras Yield Edges Higher to 1.964% in Latest Auction

The yield on Spain’s 3-month Letras del Tesoro inched up in the latest auction, rising to 1.964% from a previous level of 1.939%, according to data updated on 10 March 2026.

The marginal increase in the short-term government borrowing cost suggests a modest firming in money-market rates and investor return expectations at the very front end of Spain’s yield curve. While the move is small in absolute terms, it will be closely watched by market participants as an indicator of sentiment toward Spanish sovereign risk and the broader interest rate environment in the euro area.
