AI summary

The Official Cash Rate (OCR) is the main tool the Reserve Bank of New Zealand (RBNZ) uses to keep inflation between 1-3%. It's the interest rate at which the RBNZ lends to commercial banks.

Changes to the OCR directly influence the interest rates banks offer on mortgages, loans, and savings accounts. A higher OCR makes borrowing more expensive to cool the economy, while a lower OCR stimulates spending. Homeowners can manage rate changes through interest rate averaging.
