AI summary

The Official Cash Rate (OCR) is the interest rate the Reserve Bank of New Zealand (RBNZ) charges retail banks. It's the RBNZ's main tool for controlling inflation by influencing borrowing and saving rates for consumers.

A higher OCR increases borrowing costs to slow spending and curb inflation, while a lower OCR stimulates the economy. To manage the impact on their home loan, homeowners can use interest rate averaging by splitting their mortgage into multiple fixed-term portions.
