Cheap fixed specials are on borrowed time — what wholesale funding costs mean for lock conversations

Floating rates already moved after the OCR lift. The next pressure on fixed specials may come from a different place: wholesale funding costs, not another OCR day.

That matters for lock conversations with first-home buyers and movers. The useful response is readiness — docs, numbers, and a clear 1-year vs 2-year discussion — not FOMO.

Floating moved; fixed may be next for another reason

On 2 September the OCR rose 25bp to 2.75%. Banks have already passed a lot of that through on floating (see coverage such as interest.co.nz on ANZ and peers).

Fixed specials are a different animal. Advertised 1–2 year deals sit on top of what banks pay for wholesale funding. When that cost rises and the gap to specials shrinks, banks have less room to keep the headline rates where they are — even if the next Monetary Policy Review is still weeks away (28 October).

What changed (Tony Alexander, 17 Sep)

In a OneRoof column on 17 September, Tony Alexander set out the wholesale picture:

• Bank 2-year wholesale funding cost: about 3.7% two weeks earlier → just over 4% now
• Typical gap vs best advertised 2-year specials was around 1.8% over the past two years; now closer to 1.4% — near the lowest since late 2023
• He expects 2-year fixed lifts in the order of ~0.2%–0.4%, and leans toward the ~0.2% end given soft sales and little FOMO
• 1-year may need closer to ~0.3% in practice; the 5-year gap is larger, but a full catch-up looks unlikely

Drivers he points to are mostly offshore: US deficit and bond selling, AI / data-centre bond issuance, inflation complacency abroad — not only the NZ OCR path.

Important: that 0.2%–0.4% range is an analyst view, not a bank announcement or a guarantee. Check live lender specials before you quote a number to a client.

What it means for borrowers

• If you're close to locking: get the file ready so you can compare today's specials properly — don't wait for a rumour to become a rate card.
• If you're waiting for "one more cut": wholesale pressure can reprice short fixes even when OCR day is quiet.
• Election backdrop: Alexander also notes buyers staying cautious as rates firm, and investors dampened by the election; jobs may improve, but that's more a 2027 story than a reason to delay docs.

Optional market colour: Cotality Pulse / interest.co.nz (17 Sep) flags movers (not FHBs) as a large drag on 2026 sales — another reason soft activity doesn't mean specials stay cheap forever.

Broker checklist (use this week)

1. Stale pre-approvals — if the letter is old, get a refresh conversation booked before specials move
2. Docs ready — payslips, bank statements, ID, expenses, debts — so lock day isn't archaeology
3. 1y vs 2y without FOMO — walk the trade-off with today's live specials; don't sell urgency you can't evidence
4. Separate OCR from wholesale — clients often hear "RBNZ" for every rate move; short fixes can reprice on funding margins alone

Bottom line

Floating already reflected the OCR. Short fixed specials may be next because wholesale margins are thin, not because someone announced a new OCR. Treat the Alexander range as a signal to prepare, not as a guaranteed lift.

Get broker-ready under today's rules. Then decide lock timing with live numbers — not headlines.
