The mortgage credit market is undergoing a major shift at the beginning of 2025. After a rapid increase between 2022 and 2023, interest rates have been continuously declining for more than a year, with the hope that they will fall below the symbolic threshold of 3% in the coming months. This evolution, driven by the slowdown in inflation and the accommodative monetary policy of the European Central Bank (ECB), is attracting the attention of households and investors. However, these promising figures are set against a fragile economic context, characterized by low growth and rising financial uncertainties. It therefore becomes crucial to understand the underlying issues and their implications for the future.
