Administration officials and President Trump have sent conflicting messages in recent days about what, if any, steps they might be willing to take to support growth. They have not opened active negotiations with leaders in the House and Senate over any sort of a large-scale stimulus bill.

On Friday, congressional aides said administration officials were weighing tax relief for airlines and cruise ships, along with potential efforts to calm markets and reduce volatility in trading. That could include a possible bank holiday, in which financial institutions are closed.

It could also include reinstating the “uptick rule” — a regulation created in the wake of the Great Depression to prevent short-sellers — who bet that a given stock will fall — from short-selling a stock whose price is falling. The rule, which was eliminated in 2007, allowed investors to short a stock only after the last trade was equal to or higher than the prior trade.

On Friday, the director of the National Economic Council, Larry Kudlow, said on CNBC that he, Treasury Secretary Steven Mnuchin and others in the administration have been discussing “a targeted approach, a more micro approach” to help the economy and not a “gigantic macroeconomic fix.” He suggested that could include aid to sectors that have suffered from virus-related setbacks, like tourism.

Mr. Mnuchin has been discussing a range of measures that Treasury could use to buttress the economy, including allowing some industries to defer tax payments, and he has been talking to financial regulators about ways to allow banks increase lending to specific industries.

Mr. Trump has suggested that he would be happy to see Democrats in Congress move to cut payroll taxes for a year. But asked repeatedly by reporters on Friday if the economy needed fiscal stimulus, Mr. Trump would only promote the strength of the latest jobs report — while calling on the Fed to continue cutting interest rates.
