Housing prices are a critical factor in consumer spending and play an important role for price developments. However, in recent years, the interest of central banks in real estate markets has gone beyond this direct effect on inflation. Nearly all major institutions, such as the European Central Bank, the OECD, the International Monetary Fund and the European Commission, are focused on the dynamics of real estate prices and the factors that influence them. Researchers and politicians increasingly consider that real estate markets play a decisive role in the transmission of monetary policy impulses. Key interest rate changes can have an intermediate effect on the economy via real estate prices and may influence or initiate economic upswings and downturns.
