U.S. oil markets had a muted reaction on Monday after Washington slapped sanctions on Venezuelan President Nicolas Maduro but experts say broader oil-sector and financial sanctions may be the only way to make the Venezuelan government feel economic pain, Reuters reported.
The move came after Sunday's vote creating a new legislative superbody with the power to dissolve state institutions such as the opposition-run Congress. Countries around the world denounced the vote while Washington called it a "sham."
All of Maduro's assets subject to U.S. jurisdiction were frozen, and Americans are barred from doing business with him, the U.S. Treasury Department said.
Treasury Secretary Steven Mnuchin, when asked about oil sanctions against Venezuela, said the U.S. would consider all options, keeping the possibility of trade flow disruptions alive.

Traders and analysts said the sanctions, in their current state, would not affect oil flows to or from Venezuela.
"The latest sanctions are more symbolic than anything else, as the oil sector remains exempted," said UBS oil analyst Giovanni Staunovo.
The market had expected a likely ban on U.S. exports of lighter crude that Venezuela mixes with its heavy crude.
Other options had included individual sanctions or various measures to restrict the Venezuelan government and state oil company PDVSA's access to the U.S. banking system.
Such moves might help Maduro in the realm of public opinion, said Adam Sieminski of the Center for Strategic and International Studies think tank and former head of the U.S. Energy Information Administration, prior to the announcement.
"If we impose sanctions on Venezuela, we're giving Maduro a scapegoat. He can blame his country's problems on the United States," he said.
Venezuela is a key source of heavy sour crude for U.S. refiners. U.S. imports of Venezuelan crude in the first four months this year averaged 724,000 barrels per day (bpd).
The country has become more reliant on imports for blending due to problems at its refiners, which are running far below capacity. Venezuela took in an average of nearly 87,000 bpd of American-made fuels so far this year.
U.S. refiners such as Valero Energy Corp (VLO.N) and Marathon Petroleum Corp (MPC.N) have been shifting away from processing heavy crudes such as those supplied by Venezuela and other OPEC producers.
