AI summary

Understanding NZ's mortgage rate history provides valuable context for today's homeowners. Current rates are relatively low compared to historical peaks, which reached over 20% in 1987.

Major events like the 2008 Global Financial Crisis and the COVID-19 pandemic caused significant, unpredictable shifts. Actions by the Reserve Bank during these periods led to dramatic rate cuts followed by rapid increases to manage inflation.

The key lesson is that rates are temporary, so homeowners should prioritize affordability and consider splitting loans.
