AI summary

The Official Cash Rate (OCR), set by the Reserve Bank of New Zealand (RBNZ), is the main tool used to control inflation. It's the interest rate at which retail banks borrow money, directly influencing consumer mortgage and savings rates.

A higher OCR aims to cool the economy by making borrowing more expensive, while a lower OCR stimulates spending. To manage risk from rate changes, homeowners can use interest rate averaging—splitting their mortgage into portions with different fixed-term lengths.
