The US dollar climbed to levels close to a five-week high on Tuesday, driven by investor positioning ahead of the Federal Reserve's upcoming policy statement.

Market participants are closely monitoring the central bank's communication for signals on the future path of interest rates, particularly as inflation risks show signs of rebounding.

The greenback's advance occurred despite a concurrent decline in oil prices, which typically exerts downward pressure on the currency by reducing import costs and easing inflationary pressures.

The divergence suggests that rate expectations are currently dominating currency flows, with traders pricing in a more hawkish stance from the Fed than previously anticipated.

Recent reports indicate growing pressure on the Federal Reserve to raise interest rates as price risks resurface.

This shift in sentiment has prompted a notable repricing in Fed funds expectations, contributing to the dollar's resilience.
