1. Fed rates decision: The US Federal Reserve is expected to raise its benchmark interest rate by a quarter of a percentage point for the third time this year, to a range of 2% to 2.25%.

If it happens, it will be he eighth hike since late 2015. Four more moves before the end of 2019 may be in the cards.

At the same time, the Fed is trimming its $4.5 trillion balance sheet — an experiment that could contribute to higher borrowing costs as foreign central banks follow suit and unload bonds.

Fed Chairman Jerome Powell will hold a news conference after the decision is issued at 2:00 p.m. ET.

Investors want to hear more about how the central bank is contending with risks to economic growth, including the ballooning trade war and rising oil prices.
