AI summary

The Official Cash Rate (OCR), set by the Reserve Bank of New Zealand, is the primary tool used to manage inflation. It directly influences the interest rates banks offer on mortgages, loans, and savings accounts.

A higher OCR makes borrowing more expensive, which helps to slow spending and reduce inflation. Conversely, a lower OCR stimulates the economy. Homeowners can protect themselves from rate fluctuations by using interest rate averaging—splitting their mortgage into portions with different fixed-term lengths.
