The global financial landscape is experiencing a positive shift as both the US and UK witness significant declines in inflation rates.

In the United States, the latest inflation figures, released on Tuesday morning (Australian time) reveal a more significant drop than economists had predicted. October's inflation rate decreased to 3.2%, marking the first decline in four months. This unexpected downturn prompted a sharp fall in Treasury yields.

The reaction in the US stock market was noteworthy, with both the S&P 500 and Dow Jones posting daily gains earlier this week.

Core US inflation, excluding volatile food and energy prices, decreased from 4.1% to 4% year on year. The benchmark 10-year Treasury yield hit a three-month low of 4.43%, retracting slightly to 4.45% on Wednesday night. Futures markets in the US are signaling a zero percent probability of the central bank raising rates at its upcoming December policy meeting.

Across the Atlantic, the United Kingdom experienced a noteworthy reduction in annualised inflation, dropping from 6.7% in September to 4.6% in October. This exceeded economists' predictions of 4.8%. While both countries still grapple with inflation rates above their 2% targets, these developments affirm a positive downward trend in global inflation. Notably, the UK's inflation, which peaked at 10.7% in November 2022, has halved over the last 12 months.

Tyson Roberts, Managing Director of Vista Financial Group, interprets this data as encouraging news that will likely influence interest rates in Australia. He underscores the close connection between the Australian and global economies, predicting a favourable impact on Australian mortgage holders. Roberts notes, "In theory, this should decrease the likelihood of an interest rate hike in December. However, additional local data in the coming weeks will provide more insight into the Reserve Bank of Australia's next move."

Shifting focus, Australia reported a 0.2 percentage point increase in the unemployment rate to 3.7% in October, according to data from the Australian Bureau of Statistics (ABS). The ABS also reported a 0.1 percentage point increase in the employment-to-population ratio to 64.5% and a 0.2 percentage point rise in the participation rate to 67.0%.

While any rise in unemployment is concerning and distressing for those directly impacted, it signals a likelihood that interest rates will remain stable in December.
