Copper prices on the London Metal Exchange (LME) edged up on Tuesday, with three-month contracts trading 0.2% higher.

The modest gain reflects cautious positioning ahead of the release of US consumer price index (CPI) data, which markets view as a critical indicator of the Federal Reserve’s next policy move.

Traders are increasingly pricing in a potential rate hike as early as December, a shift that marks the first such expectation in the current cycle.

This repricing is driven by growing concerns that persistent inflation may force the central bank to maintain a tighter monetary stance for longer than previously anticipated.

The copper market’s reaction underscores the broader sensitivity of industrial metals to macroeconomic signals.

As US Treasury yields continue to rise following the Federal Open Market Committee’s recent policy statement, investors are digesting the implications of a higher-for-longer interest rate environment.
