Mortgage interest rate history NZ: How do today’s rates compare?
Spoiler: The boomers had the highest rates of all
AI summary
Understanding New Zealand's mortgage rate history provides valuable context for homeowners. Rates have been highly volatile, peaking at an incredible 20.5% in 1987 following deregulation.
More recently, major events like the 2008 GFC and the COVID-19 pandemic caused significant swings, with rates dropping dramatically before rising again due to inflation. The key lesson is that interest rate levels are temporary and unpredictable. Homeowners should focus on ensuring they can afford repayments through economic changes and consider splitting their mortgage.
