Aussie Dollar Hits 8-Week Peak as Inflation Surprises Shake Markets

Source: Kapitales Research

Highlights:

• Australian inflation beat estimates: CPI 3.8% YoY, trimmed mean 3.3%, reversing RBA outlook.
• Fed rate-cut probability surged to ~85% for Dec 10, weakening U.S. dollar pressure.
• Australian GDP forecast of 0.7% QoQ could mark 2.2% annual growth, boosting AUD fundamentals.

The Australian Dollar Currency (AUD/USD) is not issued by a publicly traded company, so no corporate ticker exists. However, AUD/USD is a globally tracked market instrument. At the time of writing, the exchange rate closed last week at US$65.50¢, logging a 1.5% weekly rise, the strongest finish in eight weeks. Momentum built as Australian inflation numbers beat forecasts and U.S. rate-cut bets spiked, easing pressure on the U.S. dollar.

???????? Inflation Surprise Shifts RBA Sentiment

Australia’s October Consumer Price Index (CPI) printed above estimates, landing at 3.8% year-on-year, while the trimmed mean — a key core inflation measure — held at 3.3%. The hotter-than-expected result flipped market expectations. Traders moved from assuming a future RBA rate cut in 2026, to now pricing in a mild possibility of a rate increase instead, signalling renewed hawkish energy around the Reserve Bank of Australia.

Adding to AUD strength, the Reserve Bank of New Zealand (RBNZ) delivered a 25-basis-point rate cut, but paired it with firm inflation language, creating a spill-over boost for the Australian dollar as interest-rate outlooks across the region were reassessed.

???????? U.S. Rate-Cut Bets Surge

Meanwhile in the U.S., expectations ahead of the Federal Reserve’s December 10 policy meeting shifted rapidly. At the time of writing, the market-implied probability of a 25-basis-point U.S. rate reduction sits near 85%, climbing sharply from about 30% in mid-November. The swing came after softer U.S. inflation commentary encouraged traders to bet on looser monetary policy, reducing yield advantages of holding the U.S. dollar.

Japan and U.S. Data Add Crosswinds

Early week sentiment was mixed. S&P 500 futures opened lower, slipping 0.7%, weighed by increasing speculation of a Bank of Japan interest-rate increase, which revived demand for the yen and injected caution into equity markets. Investors will now closely track a stream of U.S. indicators, including Core PCE inflation, consumer spending figures, ISM manufacturing, and especially ISM services PMI, to test whether U.S. growth remains stable under easing rate policy.

Australian GDP Could Sustain AUD Rally

Domestic growth data may shape the next move. Australia’s Q3 GDP is forecast to expand 0.7% quarter-on-quarter, potentially lifting annual growth to 2.2%, the fastest pace since early 2023. If achieved, it would mark the country’s strongest economic acceleration since early 2023 and lend fundamental support to the currency's recent climb.
