Oil Drops Nearly 20% After Trump’s Iran Deal Claim; Markets Split

Brent crude fell 4.5% on Friday to about $86.30, its weakest level in nearly two months, and has lost almost 20% over the past month after President Donald Trump told reporters, “We just made a great settlement of the war with Iran, and we’re going to be subject to finalization of documents, which should get done over the next few days. We’ll probably have a signing, maybe in Europe — and it’s a great thing.” No formal agreement has been signed. A semi-official Iranian agency reported Tehran had not approved any initial memorandum and Iranian officials urged caution, rejecting earlier “deal-imminent” statements. Traders sold in response to the announcement amid expectations that a signed agreement could restore flows through the Strait of Hormuz.

The Brent prompt spread, which measures the premium for immediate delivery over the next-month contract, has collapsed about 89% from a wartime peak near $10.27 to roughly $1.11. A positive prompt spread reflects backwardation, where buyers pay extra for prompt barrels because physical supply is tight. At about $1.11 the spread remains above the pre-war level near $0.24 and has not moved into contango, which would indicate an outright surplus. Data from an international energy agency show observed global inventories, including oil on water, declined by about 250 million barrels over March and April, or roughly 4 million barrels a day.

Prediction-market prices point to a slower timetable for a signed, permanent settlement. Traders on a prominent prediction market assign roughly 14% odds of a signed deal by June 15 and 33% by June 30. Probabilities rise to about 41% by July 31, 56% by August 31, and exceed 70% by October and December. Those markets resolve on a signed permanent agreement, a higher bar than the physical reopening of tanker routes.

Options activity on a U.S.-listed Brent fund shows mixed signals. The put-to-call ratio by session volume fell from 0.11 to 0.04 as call volume dominated recent trading sessions. The put-to-call ratio measured by open interest remained near 0.10, indicating new call trades did not persist in the standing book. Those metrics are consistent with traders buying short-term upside protection rather than converting to long positions in the open-interest record.

Crypto derivatives on a major venue show net short exposure. Analytics indicate whales are net short about $16.9 million and historically profitable smart traders are net short about $3.4 million on a Brent perpetual contract. Net taker flow reached negative $58.2 million over 24 hours and the funding rate runs near 17.4% annualized, with longs paying shorts. The funding structure produces carry for short holders while the positions remain open.

The datasets diverge on timing and persistence. The futures curve has priced much of a near-term reopening premium, prediction markets assign a longer timeline for a signed settlement, options flows show buying of upside protection in open sessions, and crypto perpetual swaps display net short positioning among large accounts.
