AI summary

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

Raising the OCR helps fight inflation by increasing borrowing costs, but it can risk a recession. Lowering it stimulates the economy but may fuel asset bubbles. To manage fluctuating mortgage rates, homeowners can use interest rate averaging by splitting their loan into different fixed-term portions.
