The Official Cash Rate, explained in plain English

Few numbers in New Zealand life do more quiet work than the Official Cash Rate. It’s set by the Reserve Bank of New Zealand’s Monetary Policy Committee, reviewed on a published schedule through the year, and it shapes the interest rates banks offer on everything from home loans to term deposits.

What the OCR actually is

The OCR is the interest rate the Reserve Bank pays on money commercial banks hold with it overnight, and the anchor for what banks charge each other. Because banks price their own lending and savings products off that anchor, a change in the OCR ripples outward into the rates ordinary customers see.

Why it moves

The Reserve Bank’s job is to keep inflation low and stable while supporting employment. When inflation runs hot, raising the OCR makes borrowing dearer and saving more attractive, which cools spending. When the economy needs support, cutting the OCR does the opposite. It is a blunt tool, applied carefully.

What it means on your street

Mortgage holders feel OCR changes at refixing time. Savers see it in deposit rates. And local businesses feel it twice — in their own borrowing costs, and in how freely their customers spend. The quiet Tuesday at your local café can trace a line, eventually, back to a decision made on The Terrace in Wellington.

Reading OCR news without the noise

Two things matter more than the headline number: the direction of travel over several decisions, and the Reserve Bank’s published reasoning. One announcement rarely changes a household’s maths; a year of them usually does. For decisions about your own situation, talk to a licensed financial adviser.
