AUD/CAD reaches 1.0150 by October 28, 2026 in the base case, 1.0300 in the bull case and 0.9750 in the bear case, driven by a 210 basis-point policy-rate gap that the Reserve Bank of Australia (RBA) is still widening while the Bank of Canada (BoC) holds.
AUD/CAD traded at 0.9959 on September 18, 2026, up 1.22% over one month and 9.77% over 12 months (Trading Economics). The mechanism is the two-year government bond spread, 169 basis points in the Australian dollar’s favour and 75 basis points wider than a year ago. What follows shows why the October 28 Bank of Canada decision is the settlement date for that gap — and what would break the call.
Key Levels:
• Asset: AUD/CAD spot 0.9959 — Trading Economics tick data, September 18, 2026
• Base case target: 1.0150 by October 28, 2026 — the 169 basis-point two-year spread carried forward plus the RBA increase priced for September 29
• Bull case target: 1.0300 — an RBA increase plus Brent converging on the Energy Information Administration (EIA) forecast of $90/bbl for the second half of 2026
• Bear case target: 0.9750 — an RBA hold on September 29 and an October 28 Monetary Policy Report (MPR) that flags energy pass-through into core inflation
• Major resistance: 0.9991 — the 2021 cycle high; parity has not traded since 2018
• Major support: 0.9840 — the mid-August level implied by the 1.22% one-month gain
• Invalidation level: weekly close below 0.9750
Methodology: what this call is built on, and what it leaves out
Every rate, yield and price here was collected between September 17 and September 19, 2026. Policy rates come from the Bank of Canada’s September 2, 2026 press release and the RBA’s Cash Rate Target statistics page; two-year government bond yields are Trading Economics closes for September 18, 2026; inflation figures from Statistics Canada’s August Consumer Price Index (CPI) release of September 14, 2026 and the RBA’s August Statement on Monetary Policy; oil forecasts from the EIA Short-Term Energy Outlook of September 9, 2026. Central-bank meeting dates were taken only from bankofcanada.ca and rba.gov.au, never from secondary summaries. Two caveats: Commitments of Traders (COT) positioning is not cited because no clean read for the week ending September 15, 2026 could be verified against Commodity Futures Trading Commission files, and the implied probability of a September 29 RBA increase is not a single number — published estimates in the week to September 18, 2026 ranged from 72% to 87%.

The 210 basis-point policy gap between Australia and Canada is the widest of any G10 currency pair that excludes the Japanese yen, and it is the product of two central banks that moved in opposite directions through 2026. The RBA raised the cash rate target three times this year — to 3.85% on February 4, 4.10% on March 18 and 4.35% on May 6 — then held in June and August while keeping further increases on the table. The Bank of Canada has now held at 2.25% for seven consecutive meetings, with the Bank Rate at 2.5% and the deposit rate at 2.20%. The gap is not a forecast but a settled fact the market has been slow to price into the cross: AUD/CAD has advanced 9.77% in 12 months against a 75 basis-point widening in the two-year spread.
“The Board will raise interest rates further if that is what is required to bring inflation down in a timely way.”
— Michele Bullock, Governor, Reserve Bank of Australia (RBA media conference, August 11, 2026)
The mechanism: why October 28 is the settlement date
The calendar does most of the work. The RBA’s Monetary Policy Board meets on September 28–29 and again on November 2–3, per the RBA’s published schedule; the Bank of Canada announces on October 28, 2026 at 09:45 Eastern Time with a full Monetary Policy Report. One confirmed Australian policy event lands inside the window, followed by a Canadian event whose likeliest outcome is another hold. If the RBA moves to 4.60% and the BoC stays at 2.25%, the policy gap opens to 235 basis points.
Australia’s inflation problem justifies the move. Headline inflation was 3.9% year-ended in the June quarter and trimmed mean 3.6%, with the August 11 Board statement noting inflation “is not expected to return to around the midpoint of the target range until late 2027”. Canada’s problem is narrower: Statistics Canada put CPI at 3.0% in August, but 2.4% excluding gasoline and 1.9% on the trimmed-mean core. Canada has an energy shock; Australia has a capacity problem. Central banks respond to the second and look through the first.
The steelman for the other side is oil. Brent settled at $103.21/bbl on September 18, 2026, up 13.37% in a month and 55.77% in a year, and Canada’s economy grew 3.3% in the second quarter. A windfall that size normally produces a stronger Canadian dollar than the one now trading. If the BoC decides on October 28 that high crude has stopped being a relative price and become inflation, the hold turns hawkish and the front end of the Canadian curve reprices. The Canadian two-year already yields 107 basis points above the policy rate.
What the model misses
A rate-differential model of a commodity cross assumes the commodity legs cancel. They do not cancel here. Australia’s export mix is anchored by iron ore, which reached $105.14/tonne on September 4, 2026, its highest since January; Canada’s is anchored by crude up 55.77% in a year. Both terms-of-trade stories are positive, which flatters the Australian dollar’s carry advantage by removing the commodity drag that would normally offset it. The framework also assumes the RBA increase arrives — and with implied-probability estimates spanning 72% to 87% and Australian bank forecasts split between NAB, UBS and Morgan Stanley in the September camp and ANZ, CBA and Westpac in the November camp, a hold pushes the catalyst past the settlement date. The 2021 high at 0.9991 has also capped this cross once already, and round numbers a cross has spent seven years beneath attract option-related selling on the first approach.
“The longer oil prices and refinery margins stay high, the greater the risk that higher energy prices spill over and turn into persistent inflation.”
— Tiff Macklem, Governor, Bank of Canada (opening statement, September 2, 2026)
What would invalidate this call
The base case to 1.0150 breaks if ANY ONE of these four signals fires:
- The RBA holds at 4.35% on September 29, 2026. The only confirmed Australian catalyst inside the window disappears, leaving the cross on carry alone until November 3.
- The October 28 MPR revises Canadian core inflation higher for 2027. The thesis rests on Canadian core at 1.9%. An MPR projecting energy pass-through turns a passive hold into a signalled hiking cycle and compresses the gap from the Canadian side.
- Brent closes above $115/bbl for five consecutive sessions. The EIA’s September 9 outlook has Brent averaging roughly $90/bbl in the second half of 2026; a sustained move well above that kills the assumption that Canada’s energy windfall fades before the decision.
- AUD/CAD posts a weekly close below 0.9750. That surrenders the move built since mid-August and says the market has stopped trading the cross on rate differentials.
What to watch next
Three dated events decide this. The RBA announces at 14:30 Sydney time on September 29, 2026; watch whether any move to 4.60% is unanimous, as the August hold was, or split, as the March increase was at five votes to four. Canada’s September CPI lands before October 28, and the number that matters is trimmed-mean core, not headline — a print above 2.2% changes the Canadian side of this trade. The Bank of Canada then announces at 09:45 Eastern Time on October 28 with the MPR, and again on December 9. On the chart, 0.9991 and parity are the gates the base case must clear.
TL;DR
AUD/CAD at 0.9959 is trading a 210 basis-point policy gap and a 169 basis-point two-year yield spread that widened 75 basis points over 12 months (Trading Economics, September 18, 2026). The RBA has raised three times in 2026 and kept further increases open; the Bank of Canada has held at 2.25% for seven meetings. Base case 1.0150 by the October 28 BoC decision, bull 1.0300, bear 0.9750. The call breaks if the RBA holds on September 29, or if the October 28 Monetary Policy Report revises Canadian core inflation higher.
FAQ
Why trade AUD/CAD rather than AUD/USD or USD/CAD?
The cross strips out the US dollar, so the Federal Reserve is not a variable. What remains is a clean comparison of two commodity economies whose central banks sit 210 basis points apart. Our AUD/USD energy-windfall analysis and USD/CAD oil-assumption case both had to model the dollar leg; this one does not.
What exactly happens on October 28, 2026?
The Bank of Canada publishes an interest rate announcement at 09:45 Eastern Time with a full Monetary Policy Report and a press conference. The MPR matters more than the rate itself, because it carries the revised inflation and growth projections that would reveal whether high crude has begun feeding into Canadian core inflation.
Is the RBA increase on September 29 already in the price?
Partly. Published estimates of the implied probability in the week to September 18, 2026 ranged from 72% to 87%, so a move to 4.60% is largely but not fully discounted. The tradeable content sits in the statement — whether the Board signals a further increase at the November 2–3 meeting, as it did in August.
How does this compare with the other Australian dollar crosses?
The same divergence logic drives our GBP/AUD call into the November RBA decision and the AUD/NZD path through the Reserve Bank of New Zealand. AUD/CAD carries the widest policy gap of the three, which is why its target sits furthest from spot.
