SFA Z-Score AUD/CHF : Aussie Deeply Oversold Against the Franc
Our SFA Z-score indicator is flagging an extreme divergence between the Australian dollar index and the Swiss franc index. Since October 28, the spread between the two currency indices has slumped to −4 standard deviations. It points to deeply oversold conditions and suggests the bearish impulse may be running out of steam. A corrective bounce in the pair is already underway.
The Aussie’s slide began on October 28, following the release of September inflation data. Consumer prices rose 0.8% month-on-month, and annual CPI accelerated to 4.3% from 4.0%, ahead of the 4.2% consensus. Yet the Australian dollar still came under pressure, for two reasons. First, a broad risk-off tone weighed on the currency, and the Aussie, as a classic risk-sensitive currency, retreated alongside other high-beta FX. Second, while inflation ran hot, it was not hot enough to convince the market that the tightening cycle had further to run. The upside was driven largely by transitory factors: a spike in fuel prices and a seasonal jump in travel costs.
The second leg lower came from the Reserve Bank of Australia’s November 3 meeting. As widely expected, the central bank raised the cash rate to 4.85%, its fifth hike this year. However, the decision was far from unanimous, with a 6–3 split vote. Moreover, the September pledge to raise rates further “if needed” was dropped from the statement. The takeaway is that the RBA is now heading for a pause. With no fresh catalysts on the horizon, the Aussie is left relying solely on its existing rate differential. The domestic backdrop offers little help either: unemployment is gradually rising and house prices are falling.
The decline in AUD/CHF was amplified by a firmer Swiss franc. Mounting tensions in the Middle East and widespread protests across Europe pushed investors toward safe-haven assets. Risk aversion intensified in the run-up to the US midterm elections. As the S&P 500 slipped, capital rotated out of risk-sensitive commodity currencies and into the franc.
In the near term, the pair could retest the lows around 0.5680 should risk-off flows return. The next key catalysts for the Aussie are the minutes of the RBA’s November meeting on November 17 and October CPI data on November 25. Over the medium term, the extreme reading on the SFA indicator tilts the odds toward mean reversion, meaning a move higher in AUD/CHF. If the Aussie’s recovery gains traction and tensions across global markets ease, AUD/CHF could rebound toward the 0.5780–0.5850 range.
