AUD/NZD slips to 1.2331 on a narrower cash-rate gap

AUD/NZD reaches 1.2331 by December 8, 2026 in the base case, 1.2463 in the bull case and 1.2133 in the bear case. The Reserve Bank of Australia fixed the pair at 1.2401 at 4.00 pm Sydney on November 6, 2026, and the cash-rate gap is 210 basis points. What follows maps a 25 basis point reversal of that gap onto the October 27 cross and sets out four observations that retire 1.2331.

Key Levels:

• Asset: AUD/NZD at 1.2401 — Reserve Bank of Australia, 4.00 pm Sydney, November 6, 2026
• Base case target: 1.2331 by December 8, 2026 — October 27 European Central Bank cross, 1.9552 divided by 1.5856
• Bull case target: 1.2463 if the gap holds or widens — November 4 Sydney fixing
• Bear case target: 1.2133 if the gap narrows 50 basis points — October 27 cross minus 198 pips
• Major support: 1.2286 — European Central Bank cross, October 16, 2026
• Major resistance: 1.2529 — October 28 cross, high of August 10 to November 6
• Invalidation level: Sydney fixing above 1.2529 — that October 28 cross

How the spot and the cash-rate gap were measured

The spot is the Reserve Bank of Australia exchange-rate table: 1.2463, 1.2419 and 1.2401 on November 4, 5 and 6, per Australian dollar. Definitions put the US dollar on the WM/Reuters 4.00 pm Sydney fix and cross other rates from nearby mid-points. The cash rate target is 4.85% from November 4, next update 2.30 pm on December 8, day two of the December 7–8 meeting on the 2026 dates list. The November 3 decision lifted the target 25 basis points from 4.60%. European Central Bank reference rates from August 10 to November 6, 2026, 65 days, are New Zealand dollars per euro divided by Australian dollars per euro. The Reserve Bank of New Zealand page came back blocked, so 2.75%, the four-to-three vote and the December statement come from RNZ. December 8 is the later confirmed issuer date.

What the fixings show after the hold and the hike

Six members voted on November 3 for 4.85%, and three members preferred 4.60%. Inflation is forecast above 3% for the coming year, with the top of the 2–3% range only in late 2027. RNZ reported the 2.75% hold, an expected 4.4% December-quarter rate on fuel futures, and a 75% chance of a December rise.

AUD/NZD is the number of New Zealand dollars that one Australian dollar buys. The Reserve Bank of Australia published 1.2401 for November 6, 2026, from mid-points observed around 4.00 pm Sydney time. European Central Bank reference rates were 1.6250 Australian dollars and 2.0141 New Zealand dollars per euro, a cross of 1.2394, 7 pips under the Sydney fixing. The cash-rate gap is the Australian target of 4.85%, effective November 4, 2026, minus the Official Cash Rate of 2.75% left unchanged on October 28, 2026, which equals 210 basis points. On November 3 the target rose 25 basis points from 4.60%, so the gap stood at 185 basis points before that vote. Restoring that gap takes a 25 basis point Official Cash Rate rise with the Australian target held at 4.85%, priced off the pre-hold cross.

"Our view is that a 25bp hike today would have been the most prudent course, given the higher outlook for near-term inflation, resilience in activity indicators, the turn higher in Q3 core inflation measures."

Why 1.2331 matches a 25 basis point reversal of the gap

The 210 basis point gap favours the Australian dollar, so 1.2463 is the bull case if the gap holds or widens. An Official Cash Rate rise of 25 basis points, with Australia at 4.85%, restores the 185 basis point gap. The same comparison runs through EUR/AUD into the November decision, AUD/JPY after the split vote and EUR/NZD and an Official Cash Rate pause.

The 1.2331 base case is the AUD/NZD cross implied by European Central Bank reference rates on October 27, 2026, the last fixing before the Official Cash Rate decision. That day the euro bought 1.5856 Australian dollars and 1.9552 New Zealand dollars, and 1.9552 divided by 1.5856 equals 1.2331. On October 28 the same pair of rates was 1.5830 and 1.9833, and 1.9833 divided by 1.5830 equals 1.2529. The cross therefore rose by 0.0198, or 198 pips, on the day a four-to-three committee held the Official Cash Rate at 2.75%. The November 6 Sydney fixing of 1.2401 still sits 70 pips above 1.2331. Adding the same 198 pips below 1.2331 produces the bear case at 1.2133, the result of a second 25 basis point narrowing, to a 160 basis point gap. That print is the base-case level.

A cash rate of 5.10% on December 8, with the Official Cash Rate at 2.75%, widens the gap to 235 basis points, the condition for 1.2463.

"No, you shouldn't take it to mean anything in particular. I don't know what the next move will be. As you know, Mike, I don't give forward guidance."

Where a one-decision map stops working

Those 198 pips are one day's change between two reference rates, and oil or the US dollar can overwhelm the next print. The low cross in the 65-day file is 1.1958 on August 20, 2026, from 1.9657 New Zealand dollars per euro and 1.6438 Australian dollars per euro, so the bear case at 1.2133 sits above that low. RNZ still had Sharon Zollner on a 3.5% Official Cash Rate, past either table row.

"The Bank's tone was decidedly dovish, with a considerable amount of the Summary of Meeting dedicated to warning of various risks that could strike the domestic recovery or the global economy."

— Brad Olsen, principal economist, Infometrics (RNZ)

If December echoes that summary and Australia holds, the gap stays at 210 basis points and 1.2463 is the level that matters. The EUR/GBP premium over the deposit rate can outlast a single meeting.

What would invalidate a move back to 1.2331

The base case of 1.2331 by December 8, 2026 fails if any one of these four observations lands. Each one rebuilds the hold-day premium or leaves the gap intact:

• A 4.00 pm Sydney fixing above 1.2529. That October 28 cross is the high from August 10 to November 6, 2026, and a break rebuilds the hold-day premium.
• The cash rate target rises above 4.85% on December 8 while the Official Cash Rate is still 2.75%. The gap would widen towards 235 basis points, the condition for 1.2463.
• The December statement leaves the Official Cash Rate at 2.75%. The 25 basis point reversal mapped onto the October 27 cross would be absent even if Australia holds.
• The European Central Bank cross prints above 1.2463 on the first reference day after December 8. The drift from 1.2463 on November 4 to 1.2401 would have fully retraced.

What to watch before December 8

December 8, 2026 is the confirmed issuer date, with the cash rate target due at 2.30 pm Sydney after a December 7–8 meeting. The 4.00 pm New Zealand dollar fixing is the spot check, set against 1.2401 on November 6, 1.2463 on November 4 and 1.2529 on the October 28 cross. The European Central Bank ratio either slips under 1.2331, holds between 1.2331 and 1.2401, or gets back above 1.2463. If Australia leaves 4.85% unchanged, the December Monetary Policy Statement either narrows the gap by 25 basis points or leaves it at 210. A 3.00% Official Cash Rate with Australia on hold is the base case.

TL;DR

AUD/NZD reaches 1.2331 by December 8, 2026 in the base case, 1.2463 if the gap stays wide, and 1.2133 if it narrows by 50 basis points. The spot is the Reserve Bank of Australia fixing of 1.2401 at 4.00 pm Sydney on November 6, 2026. The gap is 210 basis points. The base-case level is the October 27 European Central Bank cross, before a hold that lifted it 198 pips to 1.2529. A Sydney fixing above 1.2529 retires the lower path.

FAQ

What is the cash-rate gap in AUD/NZD?

The cash-rate gap is the Reserve Bank of Australia cash rate target minus the New Zealand Official Cash Rate. The rates here are 4.85% and 2.75%, so the gap is 210 basis points, against 185 before November 3, when the Australian target was 4.60%. The base case maps 185 basis points onto the October 27 cross of 1.2331.

Why is the base case 1.2331 rather than a round figure?

1.2331 is the October 27, 2026 European Central Bank cross, 1.9552 New Zealand dollars per euro divided by 1.5856 Australian dollars per euro, the last fixing before the hold. On October 28 it printed 1.2529, up 198 pips. The base case unwinds that rise if New Zealand adds 25 basis points and Australia holds 4.85%.

What does another Australian hike do to the cross?

Another 25 basis point increase on December 8 would take the cash rate target to 5.10%. If the Official Cash Rate is still 2.75%, the gap widens from 210 basis points to 235. That is the bull case, priced at 1.2463, the Sydney fixing on November 4. A fixing above 1.2529 retires the base case.

Which releases matter before the horizon date?

The issuer date is the Reserve Bank of Australia announcement at 2.30 pm Sydney on December 8, 2026. The spot series is the 4.00 pm New Zealand dollar fixing, latest prints 1.2463, 1.2419 and 1.2401. European Central Bank rates supply the cross. RNZ cites a December Monetary Policy Statement, and the horizon stays on December 8.
