AI summary

The Official Cash Rate (OCR) is the Reserve Bank of New Zealand's main tool for managing inflation. It's the interest rate at which retail banks borrow money, directly influencing mortgage and savings rates for everyday Kiwis.

A higher OCR aims to curb spending and lower inflation, while a lower OCR stimulates the economy. These changes can have significant side effects, such as recession or asset bubbles. Homeowners can manage risk by using interest rate averaging—splitting their mortgage into multiple fixed-term portions.
