“The economists Òscar Jordà, Moritz Schularick, and Alan Taylor studied the sensitivity of house prices to interest rates across 14 countries and 140 years of history. They found that a 1 per cent rise in interest rates reduces the ratio of house prices to incomes by about 4 per cent. In New Zealand, for example, that ratio has risen by about half in a decade, implying a double-digit rise in interest rates to stabilise it.” — Robin Harding, FT
