Rate Hike Bets Surge: RBA at 99%, Fed at 71% Before October

Interest rate expectations shifted sharply this week, with market pricing now assigning a 99% probability of an RBA rate hike at its next meeting and 41 basis points of tightening by year-end, according to data compiled on 25 September 2026. The Fed carries a 71% probability of a hike at its next meeting and 37 bps by year-end, while the RBNZ sits at an 81% probability and 37 bps. The BoE shows an 80% probability with 34 bps priced, and the BoC a 65% probability with 35 bps.

Context — Why Rate Hike Bets Repriced This Week

The repricing reversed a brief dovish move that followed the UN General Assembly. Going into that event, oil prices fell significantly on hopes of a de-escalation and an earlier end to the Iran war. The crude selloff eased inflation concerns and produced minor dovish repricing across the board.

That move was short-lived. US President Donald Trump repeated that the US would make a deal with Tehran after the November elections, and oil prices began rising again as the market repriced the estimated timeline for the end of the conflict. The hawkish repricing that followed erased the earlier dovish bets entirely, leaving year-end hike pricing in positive territory for every central bank tracked.

The catalyst chain runs from geopolitics to crude to inflation expectations to rate pricing. Oil is the transmission mechanism, and the Strait of Hormuz is the chokepoint the market is watching. When the market lengthens its estimate of the conflict, crude rises, inflation risk rises, and hike bets firm.

The macro backdrop is one of tightening, not easing. Every central bank in the table carries positive year-end hike pricing, from 10 bps at the SNB to 41 bps at the RBA. The 2027 figures are cumulative totals expected by the end of that year, not amounts expected within 2027 alone.

Data — What the Numbers Show

Wednesday's much stronger than expected US PMI report pushed Fed hike bets higher. The probability of an October hike jumped to 70% as traders positioned for the Fed to bring hikes forward, citing the central bank's focus on a "timelier return to the 2% target."

The full year-end picture now reads: RBA 41 bps, Fed 37 bps, RBNZ 37 bps, BoC 35 bps, BoE 34 bps, ECB 33 bps, BoJ 21 bps, SNB 10 bps. Each figure is paired with a next-meeting probability.

The cumulative 2027 pricing tells a different story about relative ambition. The BoC leads at 140 bps, followed by the RBNZ at 125 bps, the BoE at 106 bps, the ECB and BoJ both at 99 bps, the Fed at 92 bps, the SNB at 84 bps, and the RBA at 65 bps. A central bank can sit low on year-end pricing and high on the 2027 total, or the reverse.

The next-meeting probabilities split the group into hikers and holders. Six central banks carry a hike as the base case: RBA at 99%, RBNZ at 81%, BoE at 80%, Fed at 71%, BoC at 65%, and no hike expectation at the ECB, BoJ, or SNB. The ECB shows a 54% probability of no change, the BoJ 68%, and the SNB 62%.

The RBA's 99% probability is the standout. It is the only reading that leaves essentially no room for a hold, and it sits alongside the lowest 2027 cumulative total in the group at 65 bps. The Fed, by contrast, carries a lower near-term probability at 71% but a higher 2027 total at 92 bps.

Analysis — What It Means for Markets

The split between near-term probability and 2027 totals matters for positioning. A high next-meeting probability with a low 2027 total suggests a front-loaded hike path, which is how the RBA screens at 99% and 65 bps. A lower near-term probability with a high 2027 total suggests a longer, slower cycle, which is how the BoC screens at 65% and 140 bps.

For rates markets, front-loaded paths steepen the short end relative to the long end. Back-loaded paths do the opposite. The eight central banks in the table are not moving in lockstep, even though all eight carry positive year-end hike pricing.

Oil is the variable that connects the group. Every dovish repricing this week traced back to falling crude, and every hawkish reversal traced back to rising crude. A sustained move in either direction would reprice the entire table, not just the commodity-linked currencies.

The constraint on the hawkish case is political. Trump faces many constraints, and an end to the war is more likely than not, with the timeline the only open question. If a deal closes, the oil bid that supported this week's hawkish repricing weakens, and the dovish bets that were erased could return.

Positioning follows the probabilities. The 99% RBA reading leaves little room for surprise in either direction, while the 54% no-change ECB reading leaves the most. Flow is likely concentrated where the market is least certain, not where it is most convinced.

Outlook — What to Watch Next

The immediate catalyst is Iran's offer to reopen the Strait of Hormuz within seven days if the US meets its terms. Iran's Foreign Minister Araghchi is staying in New York over the weekend to await a US response. A breakthrough would send oil prices quickly lower, while a prolonged stalemate or re-escalation should keep the market supported.

The second catalyst is the US response itself, which has no stated date. The third is the November US elections, which Trump named as the point after which a deal with Tehran would come. That timing anchors the market's estimate of when the conflict ends.

On the data side, the next US PMI print is the release that moved Fed hike odds most this week, pushing the October probability to 70%. Watch that series for confirmation or reversal of the hawkish repricing.

Frequently Asked Questions

What does a 99% probability of an RBA rate hike mean for borrowers?

It means the market sees a hold as nearly impossible at the next meeting. For borrowers with variable-rate debt tied to the RBA, the priced move is 41 bps of tightening by year-end, so the cost of servicing that debt rises if the market is right. Fixed-rate borrowers are unaffected until their terms reset. The pricing is a market expectation, not a central bank commitment.

Why did Fed hike odds jump to 70% for October?

The move followed a much stronger than expected US PMI report on Wednesday. Traders read the data as supporting a faster return to the 2% inflation target and brought their hike expectations forward. The 70% October probability sits within the Fed's 37 bps of year-end tightening and its 92 bps cumulative total through 2027, making the Fed a front-loaded hiker relative to its own longer path.

Which central bank has the most tightening priced by the end of 2027?

The BoC leads at 140 bps, followed by the RBNZ at 125 bps and the BoE at 106 bps. The ECB and BoJ are tied at 99 bps, the Fed sits at 92 bps, the SNB at 84 bps, and the RBA at 65 bps. These are cumulative totals expected by the end of 2027, not the amount of tightening expected within 2027 alone, so a high figure reflects a longer runway rather than a faster pace this year.

Bottom Line

Oil's round trip through the UN General Assembly erased a dovish repricing and left every major central bank priced for hikes by year-end.
