United States September CPI rose 3.7% year-over-year, exceeding market expectations and fueling anticipation of further interest rate hikes by the Federal Reserve. This economic shift has exerted downward pressure on international aluminum valuations.
Why it matters
Higher-than-expected US inflation typically prompts more restrictive monetary policy, which increases borrowing costs and weighs on nonferrous metal prices globally. Traders are currently adjusting their outlooks in response to these heightened interest rate hike expectations.
The US September CPI rose 3.7% year-over-year and 0.6% month-over-month, while the Core CPI increased by 2.6% over the same period. These indicators reflect a cooling trend against a backdrop of tightening central bank policy.
The players
US Federal Reserve
The central banking system of the United States oversees national monetary policy and interest rate adjustments.
People's Bank of China

The details
Aluminum prices are currently facing a weak trend as broader market sentiment reacts to the cooling inflationary data. Despite this pressure, solid export activity from China and domestic inventory destocking of 636,000 metric tons continue to provide some market support.
