Using information from the ECB’s Bank Lending Survey, we examine how the implementation of borrower-based macroprudential measures (BBMs) between 2009-Q1 and 2023-Q3 affected mortgage lending standards in a sample of 15 euro area countries. We find that banks generally tightened credit standards around the implementation of BBMs, with the strongest effect occurring contemporaneously. Such tightening of credit standards is observed for different types of BBMs, including limits on loan-to-value or debt-service-to-income ratios and maturities. We also find mild evidence that legally binding measures imply a stronger tightening of credit standards than measures in the form of non-binding recommendations. Finally, this tightening is more pronounced in cases where mortgage loan growth or real estate price growth is high, consistent with BBMs effectively smoothing the credit cycle.
