(Reuters) – Futures tied to Canada’s main stock index were muted on Wednesday, as investors remained cautious about the size of an interest rate cut by the U.S. Federal Reserve later in the day.

The futures on the S&P/TSX index were down 0.06% at 6:00 a.m. ET (10:00 GMT).

The U.S. Fed’s policy decision is due at 1400 ET, and the central bank is almost certainly expected to announce its first interest rate cut in more than four years.

Markets are betting on a 65% chance of a 50-basis point reduction and a 35% chance of a 25-basis point cut.

Fed rate cuts typically benefit commodity prices, especially precious and base metals, which could provide a boost to Canada’s resource-heavy stock market.
