MADRID, Jan 9 (Reuters) - Spain plans to issue around 55 billion euros ($60.10 billion) in net debt via government T-bills and bonds during 2024, some 10 billion euros less than in 2023, Economy Minister Carlos Cuerpo told reporters on Tuesday.

The total amount of debt to be issued in 2024, including redemptions of earlier bonds, is expected to be 257 billion euros, Cuerpo said, representing 17% of Spain's gross domestic product.

Cuerpo added that the government expected the country's debt-to-GDP ratio to be about 106% by the end of 2024, in line with prior estimates.

"This data reflects our economy's good performance but also a commitment toward fiscal responsibility," he said, describing the Treasury's strategy as "prudent but flexible".

In October, the Spanish Treasury had lowered the planned debt sales for 2023 to a net 65 billion euros from its previous target of 70 billion thanks to stronger-than-expected economic growth.

Cuerpo was promoted from Treasury chief to economy and trade minister on Dec. 29 to replace Nadia Calvino, who exited the cabinet after five years to lead the European Investment Bank. His appointment was widely seen to signal continuity.
