GBP/NZD to 2.3791 by October 28: the rate-gap case

GBP/NZD reaches 2.3791 by October 28, 2026 in the base case, 2.3928 in the bull case and 2.3277 in the bear case. The base case is an unchanged Official Cash Rate of 2.75% at the Reserve Bank of New Zealand review, which leaves a 100-basis-point gap over Bank Rate.

The base case rests on a policy gap a hold would leave untouched. Bank Rate is 3.75% and the Official Cash Rate is 2.75%, a gap of 100 basis points. The Bank of England does not announce again until November 5, 2026. The European Central Bank reference for GBP/NZD was 2.3523 on October 2, 2026, up 1.67% from 2.3137 on September 2, when the cash rate rose by 25 basis points. June-quarter inflation was 4.1%. Four prints under disconfirmation break the call.

Key Levels:

• GBP/NZD: 2.3523 on October 2, 2026 — ECB reference cross
• Base case target: 2.3791 by October 28, 2026 — 38.2% extension of the September 3 to October 1 range, if the cash rate is held at 2.75%
• Bull case target: 2.3928 — 61.8% extension, if the October 22 inflation print is inside the 1% to 3% band
• Bear case target: 2.3277 — midpoint of 2.2985 and 2.3568, if the cash rate rises to 3.00%
• Major support: 2.2985 — ECB low on September 3, 2026
• Major resistance: 2.3568 — ECB high on October 1, 2026
• Invalidation level: an ECB reference below 2.2985 through October 28, 2026

How the 2.3791 level was measured

Spot and the range are European Central Bank (ECB) reference rates, New Zealand dollars per euro divided by sterling per euro. Inputs of 2.0002 and 0.85033 on October 2, 2026 give 2.3523. From September 2 to October 2 the low is 2.2985 on September 3 and the high is 2.3568 on October 1, a range of 0.0583. A 38.2% share rounds to 0.0223, so 2.3568 plus 0.0223 is 2.3791. A 61.8% share rounds to 0.0360, so 2.3568 plus 0.0360 is 2.3928. The midpoint rounds to 2.3277. Policy rates are from the Bank of England (BOE) dates page and the Reserve Bank of New Zealand (RBNZ) cash-rate page.

What the reference rate and the two policy rates show

GBP/NZD is the number of New Zealand dollars one British pound buys, and the base case in this note is 2.3791 by October 28, 2026. That level is a 38.2% extension of the European Central Bank reference range from the September 3, 2026 low of 2.2985 to the October 1, 2026 high of 2.3568, added to the high and rounded to four decimal places. It applies only if the Reserve Bank of New Zealand leaves the Official Cash Rate at 2.75% at the 2:00pm review on October 28, 2026. Bank Rate is 3.75%, so a hold keeps a gap of 100 basis points. The October 2 reference was 2.3523, 1.67% above the September 2 reference of 2.3137. The bull case is 2.3928, the 61.8% extension of the same window, if the hold is joined by an October 22, 2026 inflation print inside the 1% to 3% band. The bear case is 2.3277, the midpoint of the window, if the cash rate is raised to 3.00%.

UK CPI was 3.1% in August 2026, from 2.9% in July, with core CPI at 2.6%. Excluding vehicle fuels, New Zealand inflation was 2.9% against a 4.1% headline. The RBNZ monetary-policy page sets the next inflation update at 3:00pm on October 22, 2026.

"Financial conditions will continue to work to push down on inflation, and holding Bank Rate is appropriate at this meeting. But if the conflict in the Middle East persists for an extended period, as appears to be the case, and the risk of second-round effects emerging increases, it is likely that policy may have to tighten."

Why a hold at 2.75% points GBP/NZD towards 2.3791

The policy gap on GBP/NZD is Bank Rate minus the Official Cash Rate, and it stands at 100 basis points. On September 17, 2026 the Bank of England's Monetary Policy Committee voted six to three to maintain Bank Rate at 3.75%, with three members preferring 4%. The next announcement is November 5, 2026, which is after this call's horizon, and that meeting also publishes a Monetary Policy Report. On September 2, 2026 the Reserve Bank of New Zealand's committee agreed by consensus to raise the Official Cash Rate by 25 basis points to 2.75%. The next update is 2:00pm on October 28, 2026. A hold that day leaves the 100-basis-point gap unchanged on a date when London does not reset Bank Rate. A rise to 3.00% would narrow the gap to 75 basis points. The cash-rate page says a further increase may still be needed this year so inflation can return to 2%, which is why a hold is a scenario rather than a promise.

October 28 is the only scheduled reset. The RBNZ dates table lists that review, then a statement on December 9, 2026. A rise to 3.00% is the bear case, at 2.3277. Megan Greene, Catherine L. Mann and Huw Pill preferred 4% on September 17, covered in the September hike-vote note. The sterling leg into November is in the GBP/USD path into the November MPC.

What one reference window cannot see

The extension is one daily ECB reference, not the 2:00pm New Zealand print. On September 2 the reference was 2.3137, then 2.2985, then 2.3568 on October 1. A hike can print one lower fixing and still leave a higher cross. The October 22 inflation print that the bull case needs is not out.

"Higher fuel prices have pushed inflation up to 4.1% in the June quarter, and this has put pressure on household budgets and business costs. It has also slowed the economic recovery. While monetary policy can't change global oil prices, it can and will ensure that higher fuel prices don't turn into ongoing inflation."

— Paul Conway, Chief Economist, Reserve Bank of New Zealand (Reserve Bank of New Zealand, OCR page)

What would invalidate this call

The base case to 2.3791 breaks if any one of these four signals fires:

• The cash rate is set at 3.00% or higher on October 28, 2026. The gap over Bank Rate would narrow from 100 basis points to 75 or less.
• An ECB reference prints below 2.2985 through October 28, 2026. That September 3 low is the floor the extension uses.
• The October 22, 2026 inflation update is above 4.1%. The fuel shock would still be building, six days before the review.
• UK CPI on October 21, 2026 is at or below the 2% target. August inflation was 3.1%. A print at target would remove the sterling leg of the gap.

What to watch into October 28 and the November MPC

ONS CPI is on October 21, 2026, the RBNZ inflation update at 3:00pm on October 22, and the review at 2:00pm on October 28. The reference levels are 2.3568, then 2.3791, with 2.2985 as invalidation. November 5 cannot rewrite a call that ends on October 28. December 9 is the next RBNZ statement. See the GBP/AUD divergence note and the forex desk.

TL;DR

GBP/NZD reaches 2.3791 by October 28, 2026 if the Official Cash Rate stays at 2.75%, 2.3928 if New Zealand inflation is back inside the 1% to 3% band, and 2.3277 if the cash rate rises to 3.00%. The October 2, 2026 European Central Bank reference was 2.3523, 1.67% above September 2, and Bank Rate at 3.75% leaves a 100-basis-point gap a hold would not close. The Bank of England meets on November 5, 2026, after this horizon. An ECB reference below 2.2985 breaks the call.

FAQ

What is the GBP/NZD base case into October 28, 2026?

The base case is 2.3791 by October 28, 2026 if the Reserve Bank of New Zealand holds the Official Cash Rate at 2.75%. That level is a 38.2% extension of the ECB reference range from 2.2985 on September 3 to 2.3568 on October 1. The October 2 reference was 2.3523. The bull case is 2.3928 and the bear case is 2.3277. It is a measured projection, not a trading instruction.

Does the base case require a cut in the cash rate?

No. The base case is a hold at 2.75%, not a cut. The cash rate was raised by 25 basis points to 2.75% on September 2, 2026. The September record said later moves depend on medium-term inflation risks. A rise to 3.00% or above is the bear case, and it invalidates the base case on the day of the review.

When does the Bank of England next set Bank Rate?

November 5, 2026, with the Monetary Policy Report, on the Bank of England dates page updated September 21, 2026. Bank Rate is 3.75% after a six-to-three hold on September 17, with three members preferring 4%. That meeting is after the October 28 horizon. The next announcement after it is December 17, 2026.

What level invalidates the GBP/NZD call?

An ECB reference below 2.2985, the September 3, 2026 low, invalidates the call even if the cash rate is held. The call also fails if the cash rate is 3.00% or higher on October 28, if the October 22 inflation update is above 4.1%, or if UK CPI on October 21 is at or below the 2% target. Any one of the four is enough.

Why can GBP/NZD rise when New Zealand inflation is 4.1%?

GBP/NZD prices a gap, not one inflation print. New Zealand inflation was 4.1% in the June quarter and 2.9% excluding fuels. UK CPI was 3.1% in August, with core CPI at 2.6%. Bank Rate at 3.75% is 100 basis points above the 2.75% cash rate, and London does not meet until November 5. The cross rose from 2.3137 on September 2 to 2.3523 on October 2 after the last hike.
