Interest rates have a big impact on housing prices. When interest rates go down, more people can afford to buy houses, so prices go up. This effect was seen in countries with low interest rates during COVID-19. In Korea, the impact of interest rate changes on housing prices was not very strong before the global financial crisis, but it increased a lot afterward. The impact was strongest in 2020-2021 when house prices went up. This happened because more people were relying on loans to buy houses. With interest rates going up due to inflation, a sudden change in interest rates could lead to a global housing market crash.
