Donald Trump is set to be sworn in as the 47th president of the United States on Monday.

In the build-up to his return to the White House, Trump has promised to sign of a wave of executive orders on his first day back in office as part of an early push to act on his campaign promises.

Trump is expected to announce more than 200 of these actions, which are legally binding but can still be subject to legal review. The orders are tipped to address a broad sweep of issues, including immigration, environmental regulations, and corporate diversity policies.

One key move could see Trump launch mass deportations of illegal immigrants. Media reports have suggested that Trump, who has vowed to carry out the largest deportation program in US history, will call for raids in several major cities in the opening days of his second term in office.

Investors have been awaiting more clarity around Trump's plans, especially their potential impact on inflationary pressures and possible Federal Reserve interest rate cuts this year. Stock markets are due to be closed on Monday in observance of the Martin Luther King Jr. Day holiday.
