On 8 July 2026 the Reserve Bank’s Monetary Policy Committee raised the Official Cash Rate by 25 basis points to 2.50 percent, its first increase since May 2023, with the next review scheduled for 2 September. For business owners the immediate question is what that actually does to borrowing costs — and the honest answer is that the relationship is looser than most commentary suggests.
What the OCR actually sets
The OCR is the rate the Reserve Bank pays on settlement account balances and charges for overnight borrowing. It directly governs the price of overnight money between banks, and nothing else directly.
Everything downstream — mortgage rates, business lending, term deposits — is a commercial decision made by each bank. The OCR is a powerful input to those decisions, not a control on them.
Why floating and fixed behave differently
Floating rates track the OCR reasonably closely, because they are priced off short-term funding. When the OCR moves, floating business lending usually follows within weeks.
Fixed rates behave differently, and this is where expectations most often go wrong. Fixed lending is priced off wholesale swap rates, which reflect what markets expect to happen over the term rather than what has just happened. Those expectations move ahead of the decision.
The practical consequence: by the time a rate change is announced, fixed rates have frequently already moved. Businesses that wait for an official decision before fixing are routinely acting on information the market priced in weeks earlier.
The margin over the base
Business lending is priced as a base rate plus a margin, and the margin is where most of the variation between borrowers sits. It reflects credit risk, security, sector, relationship and how much competition the bank believes it faces.
That margin is more negotiable than most borrowers assume, and it does not move with the OCR at all. A business that improves its financial reporting, reduces its concentration risk or brings a competing offer to the table can achieve a change in borrowing cost larger than several OCR decisions combined.
This is worth internalising. You cannot influence the OCR. You can influence your margin.
Deposits move slower than lending
When the OCR rises, lending rates tend to adjust faster than deposit rates. When it falls, the reverse. The asymmetry is a well-documented feature of retail banking rather than a conspiracy, but businesses holding meaningful cash balances should watch deposit pricing actively rather than assuming it follows.
What a business should actually do
- Know your reset dates. The most consequential fact about your debt is when it reprices, and a surprising number of owners cannot say without checking.
- Stress test at higher rates. Model your position two percentage points above current pricing. If that breaks the business, the problem is leverage, not the OCR.
- Split rather than guess. Fixing part and floating part removes the need to be right about direction, which almost nobody is consistently.
- Review the margin annually. It is the part you control and the part nobody reviews.
- Watch the commentary, not the announcement. The Reserve Bank publishes its Monetary Policy Statements with the reasoning and forecasts. That material tells you more about the next twelve months than the headline number does.
Reading the direction
The Reserve Bank operates under a remit targeting price stability, with an inflation target band and a focus on the 2 percent midpoint. Its published objective in July was to bring inflation back to that midpoint by mid-2027.
Understanding that framing is more useful than trying to forecast individual decisions. The Reserve Bank tells you what it is trying to achieve and publishes the data it is watching, all of it free at rbnz.govt.nz. Businesses that read the statement rather than the headline are consistently less surprised.
