The Wall Street Journal reported that the United States is preparing to board oil tankers linked to Iran and seize commercial vessels in international waters.

Digital asset markets started 2026 under heavy pressure as capital pulled back sharply in the first weeks of the year, adding to fears that a prolonged downturn is taking hold. CoinGecko data shows the selloff accelerated early in the quarter, driving one of the steepest drops in market value since 2022. Total cryptocurrency market capitalization fell 20.4% in Q1 2026, ending near $2.4 trillion after roughly $622 billion was erased. The market now sits almost 45% below its October 2025 peak. The bulk of the decline came between mid-January and early February, when macro expectations shifted after Kevin Warsh was nominated as the next Federal Reserve Chair. Investors began pricing in tighter monetary conditions, typically a headwind for high-risk assets such as crypto. Positioning also turned more defensive. Stablecoins captured part of the rotation, with total stablecoin market capitalization rising by $1.6 billion to $309.9 billion, pointing to a stronger preference for liquidity and stability. Signals within stablecoins were mixed. Tether supply fell 1.6% to $184.1 billion, its first meaningful contraction since Q2 2022, while it still held a dominant 59% share of the stablecoin market. Trading patterns across major networks echoed the caution. Solana remained the top venue for spot trading with a 30.6% share, even as its volume slid 26.5%. Ethereum strengthened into quarter-end and overtook Solana in March, taking a 27% share versus Solana's 26%. The Q1 $622 billion drawdown reinforces the "crypto winter" narrative. Even so, flows suggest capital is rotating within the ecosystem rather than exiting entirely, as investors prioritize risk control and liquidity amid tighter financial conditions.

BREAKING: Donald Trump commented on reports that Iran has again closed the Strait of Hormuz, saying "Iran can't blackmail us" with threats tied to the waterway. He added that more information should be available by the end of the day.

Monitoring by Seer Prophet Channel shows Polymarket pricing now implies a 30% chance that shipping through the Strait of Hormuz returns to normal before April 30, down 24 percentage points over the past 24 hours. Trading volume in the related event contract has surpassed $15.9 million. Under the contract rules, the outcome settles as "Yes" if IMF Portwatch data indicates the 7-day moving average of vessel arrivals reaches or exceeds 60; otherwise it settles as "No". The update comes as Iran has declined to enter new negotiations, citing U.S. maritime blockades and what it describes as excessive demands. Oil-tanker tracking services also report that two Indian vessels were turned back by the Iranian navy, with shots exchanged.

The Strait of Hormuz swung between open and closed five times this week as U.S. President Donald Trump and Iranian officials traded public statements over the world's most critical oil chokepoint. Sunday, April 12: Trump posts on Truth Social that the U.S. will impose a full naval blockade after talks in Islamabad collapse following 21 hours of negotiations led by Vice President JD Vance. Status: CLOSED. Monday, April 13: CENTCOM says the U.S. Navy blockade begins at 10 a.m. ET. Brent jumps above $95. Status: CLOSED. Wednesday, April 15: Brent trades erratically around $94–$95 as enforcement continues. Status: CLOSED. Thursday, April 16: The Pentagon says 13 ships have been turned back. Joint Chiefs Chairman Dan Caine holds a press briefing. Status: CLOSED. Friday, April 17: Iran's foreign minister, Araghchi, says on X that the strait is "completely open". Trump thanks Iran but says the U.S. blockade will remain "until transaction 100% complete." Oil slides more than 10% in a single session. Status: OPEN. Saturday, April 18: Iran reimposes restrictions after Trump maintains the blockade. IRGC gunboats fire on a tanker. Status: CLOSED AGAIN. In normal conditions, roughly 20% of global oil supply moves through the Strait of Hormuz.

BREAKING: Roughly 20 ships attempting to transit the Strait of Hormuz have reportedly reversed course following Iran's declaration that the waterway is closed.

BREAKING: Iran has closed the Strait of Hormuz.

Iran's joint military command said Saturday that control measures in the Strait of Hormuz have been reinstated, walking back a Friday statement by Foreign Minister Abbas Araghchi that the strategic waterway was open to commercial shipping. A few hours later, the UK Maritime Trade Operations (UKMTO) center reported that two gunboats from Iran's Islamic Revolutionary Guard Corps (IRGC) opened fire on a tanker transiting the strait. The ship and its crew were safe, according to the Associated Press. Tehran blamed the move on what it described as a U.S. blockade of Iranian ports, accusing Washington of breaching the April 7 ceasefire framework. Under the arrangement, Iran agreed to keep the strait open in exchange for a two-week pause in hostilities. Ebrahim Azizi, head of Iran's parliamentary National Security Commission, said vessels will once again need authorization from Iran's navy and must pay a toll before transiting. The Strait of Hormuz carries about 20% of global seaborne oil and LNG. Brent was trading near $130 a barrel before Friday's reopening announcement, which sent prices down more than 10%.
