Fed chair Janet Yellen said earlier this month that the economy is near maximum employment and inflation was moving closer to the central bank's goal. Yellen reiterated that she and other Fed leaders expect to raise rates a "few times a year" until 2019.

The Fed may also discuss President Donald Trump's new policies and their economic impact. Before Trump took office, Fed officials said there was "considerable uncertainty" surrounding his plans.

Meanwhile, German lender Deutsche Bank (DB) is facing roughly $630 million in fines for failing to deal with a Russian money-laundering scheme that used its London and New York branches.

This follows a $7.2 billion settlement Deutsche Bank reached with the U.S. last month over toxic mortgage assets and the $2.5 billion it agreed to pay in 2015 over interest rate manipulation.

Shares in the bank were up by nearly 2% in European trading.
