Energy traders are still digesting the whiplash from the U.S.-Iran ceasefire: oil plunged after the truce, then opened higher again as the market fixated on whether the Strait of Hormuz will really stay open and under what terms. Brent and WTI had both suffered their biggest one-day drops since April 2020, but prices remain well above prewar levels, leaving gasoline, shipping and inflation outlooks far from normal.
The problem is not just peace, it is plumbing. Iran has said the ceasefire is temporary and has floated transit fees for tankers moving through the strait, a choke point for about 20 percent of global oil flows. Traders are watching whether the backlog of 187 tankers inside the Gulf can start moving, while analysts warn that even $1 million to $2 million per tanker in fees would only partially offset the shock, not erase it.
That uncertainty is spilling into stocks and policy. Bloomberg said equities were set to extend gains into an eighth straight session after the first inflation reading tied to the energy spike matched expectations, helping investors look past the war for now. Meanwhile, White House aides were told in a March 24 ethics email not to use nonpublic information to bet on prediction markets such as Kalshi or Polymarket, a reminder that the frenzy around geopolitics is now colliding with scrutiny over who knew what, and when.
The episode also shows how quickly market narratives can reverse. A ceasefire bid can send the Dow to its best day in a year, knock oil sharply lower, and still leave investors staring at a fragile truce, a jammed shipping lane and the possibility that the next move comes from Tehran, not traders.
