AUD/CHF to 0.57685 by December 10: priced-in SNB gap

Australian dollar/Swiss franc (AUD/CHF) reaches 0.57685 by December 10, 2026 in the base case, 0.5882 in the bull case and 0.57301 in the bear case. The base case is the fourth-quarter forecast on the Trading Economics page, and it treats the 460-basis-point policy gap as already reflected in the price ahead of the Swiss National Bank (SNB) monetary policy assessment.

AUD/CHF was marked at 0.58029 on October 9, 2026, a yearly change of 12.08% on that same page, and it sits just under the 0.5882 52-week high on Yahoo Finance. The SNB left its policy rate at 0% on September 24, 2026 and said the franc had already depreciated by around 3% on a trade-weighted basis. The note below sets out the sourced levels, the rate arithmetic, futures positioning, and the four observations that would retire the stall.

Key Levels:

• Asset: AUD/CHF spot 0.58029 on October 9, 2026 — Trading Economics; Yahoo Finance regular market price 0.5803 at 06:43 UTC
• Base case target: 0.57685 by December 10, 2026 — Trading Economics fourth-quarter forecast
• Bull case target: 0.5882 if the high is retested — Yahoo Finance 52-week high, September 17, 2026
• Bear case target: 0.57301 if the October 1, 2026 low is revisited — Yahoo Finance daily low
• Major support: 0.57301 — October 1, 2026 low, Yahoo Finance daily series
• Major resistance: 0.5882 — Yahoo Finance 52-week high
• Invalidation level: a daily close above 0.5882 — that 52-week high ends the stall

How the December 10 levels were fixed

The horizon is the SNB time schedule, which lists the monetary policy assessment of December 10, 2026, the same date as the 2026 calendar feed. Spot at 0.58029 and the base case of 0.57685 come from the Trading Economics AUD/CHF page opened on October 9, 2026. The bull case at 0.5882, the bear case at 0.57301 and the invalidation are Yahoo Finance daily prints. The 0% rate is the September 24, 2026 SNB press release. The 4.60% cash rate is the Trading Economics Australia series through September 29, 2026, because the Reserve Bank of Australia (RBA) site did not load. Positioning is the Commodity Futures Trading Commission (CFTC) Commitments of Traders (COT) report of September 29, 2026. There is no contract on the cross. The Yahoo close rose from 0.52776 on October 8, 2025 to 0.58025, up 9.94%, against a 12.08% yearly label.

Where spot, inflation and futures sit

AUD/CHF is near the top of its yearly range. Yahoo Finance shows a 52-week low of 0.5079 and a high of 0.5882, so spot at 0.58029 is 0.00791 under the high. The monthly change is -0.26%.

Sources: Trading Economics; SNB assessment of September 24, 2026; Australian Bureau of Statistics (ABS) Consumer Price Index (CPI), released September 30, 2026; CFTC COT, September 29 versus September 22, 2026. Open interest: Swiss franc 133,872, Australian dollar 309,800. Window: May 2026 to October 9, 2026, and the week to September 29 for positioning.

AUD/CHF is the spot price of one Australian dollar in Swiss francs. On October 9, 2026 the Trading Economics page showed an exchange rate of 0.58029, a daily change of 0.0016, a monthly change of -0.26% and a yearly change of 12.08%, alongside a fourth-quarter forecast of 0.57685. Yahoo Finance, at 06:43 UTC the same day, showed a regular market price of 0.5803, a 52-week high of 0.5882 and a 52-week low of 0.5079. The base case into the SNB assessment on December 10, 2026 uses that fourth-quarter figure rather than a fresh extrapolation. The gap from 0.58029 to 0.57685 is 0.00344, smaller than the distance between the September 17, 2026 high of 0.5882 and the September 30, 2026 low of 0.57341 on the Yahoo daily series. The call is a stall under the high, not a reversal of the year's rise, and a daily close above 0.5882 would retire it.

"Since our last assessment, the Swiss franc has depreciated by around 3% on a trade-weighted basis. This depreciation was in line with the widening of interest rate differentials between the major currency areas and Switzerland."

— Martin Schlegel, Chairman of the Governing Board, Swiss National Bank (SNB introductory remarks, September 24, 2026)

Why a 460-basis-point gap can still mean a lower cross

On September 29, non-commercial Swiss franc futures were net short 24,617 contracts, narrower by 2,135 on the week, and Australian dollar futures were net short 63,239, wider by 16,425. Further franc covering leans towards 0.57685. Capitulation of the Australian dollar short is the route to 0.5882.

The Australia-Switzerland policy gap is the RBA cash rate minus the SNB policy rate. Trading Economics records the Australian benchmark at 4.60%, with the dataset running through September 29, 2026, while the SNB press release of September 24, 2026 left the policy rate unchanged at 0%. The difference is 460 basis points, against 435 basis points when the prior reading on that calendar was 4.35%. A gap of that width can keep a bid under the Australian dollar, which is why the bull case is a retest of 0.5882. It does not, on its own, require a new high. Martin Schlegel said the franc's trade-weighted depreciation of around 3% was already in line with wider interest-rate differentials. The fourth-quarter forecast of 0.57685 is that statement read across to the cross: a small give-back. The bear case, at the October 1, 2026 low of 0.57301, is the same stall taken one session beyond the forecast.

What a 0.00344 forecast does not capture

The base-case distance is 0.00344. From the September 17 high of 0.5882 to the September 30 low of 0.57341 the Yahoo series covers 0.01479, a wider band than the base case. Invalidation is a daily close above 0.5882. The inflation forecast also assumes a 0% policy rate for the whole horizon. Change that assumption and the cross forecast does not survive on its own.

Schlegel said the Bank is willing to intervene in the foreign-exchange market as necessary. That is a tail, not the base case. A 2021 note on Swiss franc volatility when the SNB chair was out of action shows a communication shock can move the franc when the rate is not the headline. The futures books are a check, not a contract on AUD/CHF.

"Moreover, our monetary policy and the recent depreciation of the Swiss franc are having a supportive effect. For 2026 as a whole, we currently expect growth of between 1.5% and 2%."

— Petra Tschudin, Member of the Governing Board, Swiss National Bank (SNB introductory remarks, September 24, 2026)

What would invalidate this call

The base case to 0.57685 by December 10 breaks if any one of these four observations prints:

• A daily close in AUD/CHF above 0.5882. That is the Yahoo Finance 52-week high of September 17, 2026. Intraday spikes do not count.
• The SNB sets the policy rate below 0% on December 10, or drops the line on foreign-exchange activity. The September 24 text kept both the 0% rate and the willingness to be active in that market.
• The RBA sets the cash rate above 4.60% on November 3, 2026. A higher rate would widen a gap the base case treats as priced and would favour 0.5882.
• Australian dollar futures swing from a net short of 63,239 contracts on September 29, 2026 to a net long before December 10. The CFTC sign on that net position is a weekly, observable test.

What to watch before December 10

October 13 brings the RBA minutes on the Trading Economics calendar. An archive note on Reserve Bank Board minutes shows what the Board emphasises. October 22 is the SNB summary of the September discussion, and October 28 is the ABS September CPI after an August reading of 4.0% and a trimmed mean of 3.6%. November 3 is the RBA decision. A note on a Reserve Bank of Australia policy statement shows how a decision is written, and December 10 is the assessment that defines this call.

TL;DR

AUD/CHF reaches 0.57685 by December 10, 2026 in the base case, 0.5882 on a retest of the high, and 0.57301 if the October 1 low gives way. Spot on October 9, 2026 was 0.58029. Trading Economics puts the yearly change at 12.08%. The SNB rate is 0% and the recorded Australian cash rate is 4.60%, a 460-basis-point gap. The stall fails on a daily close above 0.5882, on an SNB rate below 0%, or on an RBA rate above 4.60% on November 3.

FAQ

What is the AUD/CHF base case into December 10, 2026?

The base case is 0.57685, the Trading Economics fourth-quarter forecast, against a spot of 0.58029 on October 9, 2026. December 10 is the SNB assessment on the Bank's time schedule. The gap of 0.00344 is a stall under the 0.5882 high after a 12.08% yearly rise, not a reversal. The bull case is 0.5882. The bear case is the October 1 low at 0.57301.

Why does a wide rate gap not mean a higher AUD/CHF?

The gap is 460 basis points: an Australian cash rate of 4.60% through September 29, 2026, against an SNB policy rate of 0%. Martin Schlegel said the franc had already fallen by around 3% on a trade-weighted basis. AUD/CHF is up 12.08% on the year and close to 0.5882. The gap explains the rise already booked. It does not require a further leg by December 10.

What level invalidates the AUD/CHF stall?

A daily close above 0.5882 ends the stall. That is the Yahoo Finance 52-week high from September 17, 2026. An intraday print is not enough. An SNB rate below 0% on December 10, an RBA cash rate above 4.60% on November 3, or Australian dollar futures swinging from a net short of 63,239 contracts to a net long would also retire the call.

What did the SNB decide on September 24, 2026?

The SNB left the policy rate at 0% and kept a 0.25 percentage point discount on sight deposits above a threshold. It remains willing to be active in the foreign-exchange market as necessary. Conditional inflation is 0.7% for 2026 and 0.8% for 2027 and 2028, assuming that 0% rate. Swiss CPI rose from 0.6% in May to 0.8% in August.
