Oil prices fell about 3% on Tuesday as the U.S. pivots to economic sanctions rather than military strikes to pressure Iran.
Brent futures, the international benchmark, fell 3.3% to $89.14 per barrel. U.S. West Texas Intermediate crude was down 3.1% at $82.36 a barrel.
Prices have fallen more than 5% this week after the U.S. government unveiled a fresh raft of sanctions on Iran and so-called "enablers" that continue to trade with the Islamic Republic.
The White House has labeled its efforts an "economic D-Day" with Treasury Secretary Scott Bessent claiming the campaign is "the single greatest financial offensive ever." Bessent told CNBC last week that the decision to ratchet up economic pressure means a return to war is unlikely for now.
"If we are doing the maximum economic pressure, then that means that likely there will not be a large-scale kinetic restart," the Treasury Secretary said Thursday in an interview on "Squawk on the Street."
Meanwhile, the State Department is preparing to return evacuated U.S. diplomats to the Middle East as early as this week, The New York Times reported Tuesday. The return of diplomats to their posts would suggest Washington is not anticipating a return to all-out warfare.
President Donald Trump said Tuesday the U.S. Navy notified him that all mines have been cleared within international waters in the Strait of Hormuz. CNBC has reached out to U.S. Central Command for comment.
"Iran has been notified that any ship or boat placing new mines will be immediately and systematically destroyed," Trump said in a Truth Social post.
"Through Space Force, we are watching every square inch of the Strait, as we are, also, with Pickaxe Mountain and the already destroyed three other Nuclear sites," the president said. "There is a Zero Tolerance policy on mine placement in full force and effect."
U.S. Defense Secretary Pete Hegseth told reporters on Monday that the prospect of further American strikes in the Middle East remained on the table.
"If we need to use kinetic strikes, we'll use them," Hegseth said. "If Iran is foolish enough to overplay their hand or mess with the American military, we'll do what we need to do."
"Economic pressure hurts them the most right now," he said of the Iranian regime. "But by no means are we foreclosing using kinetic strikes anywhere in the Strait of Hormuz or around Iran."
Iranian Economy Minister Ali Madanizadeh said on state television that Tehran is "fully prepared" to withstand more U.S. sanctions.
"The government is and was ready and has a two-year plan to manage these events," he said. "We have our own tools and we know how to play the game."
Under the new sanctions plan, China could face ramifications for continuing to buy Iranian oil. Beijing, one of Iran's largest trading partners, has repeatedly called for a diplomatic end to the U.S.-Iran war.
