(Reuters) -Europe's STOXX 600 closed slightly lower on Monday as losses in heavyweight technology shares weighed on the index, while the focus remained on the U.S. Federal Reserve, which is widely expected to kick off its policy easing cycle this week.

All eyes will be on the U.S. central bank's interest rate decision on Wednesday, with money markets pencilling in a 61% chance of a 50-basis-point rate cut, and a total easing of 120 bps in 2024.

"With the Fed set to hop aboard the (rate-cut) bandwagon, a global easing cycle should be a tailwind for equities after the European Central Bank opted to cut rates for the second time in three months," wrote analysts at Glenmede led by Jason Pride, chief of investment strategy & research.

"Momentum behind global easing cycles has historically been a bullish signal for equities in the short-to-medium term."

Central bank rate decisions in Norway and the UK will also be on investors' radar this week.
