Here are five things you must know for Monday, March 27:

1. -- U.S. stock futures were pointing to sharp drops for Wall Street when markets open Monday following the Trump administration's failure last week to push through a health care bill.

European and Asian stocks were tumbling Monday and the dollar stumbled to a four-month low. The dollar index, a measure of the greenback's strength against a basket of six global currencies, fell to 99.12, down 0.3%. Earlier in the session, the index touched 98.85, the lowest level since after Donald Trump's election as U.S. president in November.

Gold prices rose 0.7% early Monday to $1,260.20 an ounce, the highest since Feb. 24, as the dollar declined.

The S&P 500 and Dow Jones IndustrialAverage finished lower on Friday after leaders in the House of Representatives pulled the unpopular health care bill before a crucial vote. Republican leaders pulled their bill to repeal "Obamacare" off the House floor Friday when it became clear it would fail.

The passage of the bill was seen by Wall Street as a test as to whether a Trump administration can enact all it has promised, particularly tax cuts and regulatory reform.

"Beyond the impact on health care, the vote had been seen as a test to the self-proclaimed deal-maker and the new administration's abilities to also deliver other promises, including tax and infrastructure policies," Jingyi Pan, a market strategist at IG in Singapore, told the Associated Press.

There is very little data expected on the U.S. economic calendar for Monday but two Federal Reserve officials -- Chicago Fed President Charles Evans and Dallas Fed President Dennis Kaplan -- have planned speaking engagements.
