Kiwi Dollar Plunges as New Zealand's Central Bank Shocks Markets by Holding Rates

The Reserve Bank of New Zealand held its official cash rate at 2.75% on Wednesday, October 28 — defying market pricing that put the chance of a rate hike at 95% — and the New Zealand dollar sank as much as 1.7% to an intraday low of $0.55831. It was one of the cleanest central-bank surprises of the year: almost everyone expected a hike, almost no one got one, and the currency paid for the mispricing within minutes.

What happened, in one answer

The RBNZ's monetary policy committee voted 4 to 3 to keep the official cash rate (OCR) steady at 2.75%. A Reuters poll had found 22 of 27 economists expecting the central bank to raise rates, and markets had priced a hike as near-certain. Instead, the bank paused, said two rate increases already delivered are still working through the economy, and signalled it wants to assess incoming data before moving again.

Why the kiwi fell so fast

Currency markets trade on the gap between what was expected and what arrives. When a hike is priced at 95%, traders hold the currency for the higher return they think is coming. Remove that hike and the reason to hold it disappears at the same moment for almost everyone — which is why the New Zealand dollar fell by close to one U.S. cent on the decision before consolidating just above 56 cents. The move trimmed only after Governor Anna Breman told reporters the committee still expects further OCR increases in coming meetings, adding that they may even be higher than the bank said at its September meeting.

"The market just got that wrong," said Mike Houlahan, director at Electus Financial in Auckland, who also noted the country's election is only 10 days away. Breman, for her part, said the election was not a factor in the decision.

Delayed, not cancelled — what the bank signalled next

The clearest reading from economists is that tightening has been postponed, not abandoned. Breman said the bank would likely consider another hike in December, when it publishes fresh economic forecasts, and pointed to global risks — including the unresolved war in the Middle East — and fresh inflation data as critical to the coming decisions.

ANZ chief economist Sharon Zollner called it "a close-run thing," saying some committee members thought it more prudent to watch developments over the next six weeks, with an eye on downside risks to global growth. ANZ still forecasts three more hikes — in December, February and March — taking the cash rate to 3.5% to head off persistent inflation.

Thomas Mathews at Capital Economics said the RBNZ "has delayed tightening rather than cancelled it outright" — but added that market pricing had looked too aggressive, and further dovish surprises would not surprise him.

Why the decision was genuinely hard

New Zealand's economy is sending mixed signals. It shows signs of recovery, yet unemployment remains near an 11-year high and growth is uneven. That combination produces 4-3 votes: inflation argues for hiking now, a fragile labour market for waiting. The bank has not stopped worrying about inflation — it is divided over timing.

The wider market picture on the day

The surprise landed on a day already dominated by central banks. The U.S. dollar held at a two-week high ahead of the Federal Reserve's decision later on Wednesday, where traders broadly expect no change — Fed funds futures priced an implied 91% probability of a hold, according to CME FedWatch. That contrast is the story in miniature: the Fed is expected to do exactly what markets have priced, while the RBNZ just showed how violently a currency can move when a central bank does the opposite.

What happens next

Attention now shifts to December. If inflation data stays hot, the delayed hike Breman flagged becomes the market's base case again, and the kiwi's fall could partly reverse. If growth or jobs data weakens first, the pause could stretch — and, as Capital Economics warned, produce more dovish surprises. Either way, the next six weeks of New Zealand data now carry far more market weight than they did yesterday.

FAQ

What did the RBNZ decide on October 28?

It held the official cash rate at 2.75% by a 4-3 committee vote, surprising markets that had priced a hike at about 95% probability.

Why did the New Zealand dollar plunge?

Traders had bought the kiwi expecting a rate hike and a higher return. When the hike did not arrive, that positioning unwound at once, sending the currency down as much as 1.7% to about $0.558.

Will the RBNZ still raise rates?

Governor Anna Breman said the committee expects further increases in coming meetings and may consider a hike in December. ANZ forecasts three more hikes taking the rate to 3.5% by March.

Did New Zealand's election affect the decision?

Breman said it did not. A market commentator noted the vote is 10 days away, but the central bank said global risks and fresh inflation data are what matter for its next moves.
