Finma has issued a warning to banks about the risks of mortgage loans and potential defaults, citing excessive self-regulation in lending practices. In response, UBS expert Claudio Saputelli argues that the warning is exaggerated, referencing a decline in the UBS Swiss Real Estate Bubble Index and suggesting that the supervisory authority's concerns may be influenced by external pressures. He cautions that stricter regulations could dampen demand for mortgages, as many buyers already struggle to meet affordability criteria.
