The precise terms of the U.S.-Iran MoU remain unclear, with details around thornier issues - such as Iran's nuclear programme - deferred to further negotiations during a 60-day ceasefire period.
It's also unclear whether traffic through the strait will return to normal levels any time soon. President Trump wrote on social media that the strait would reopen toll-free and that the U.S. naval blockade would be removed, declaring: "Let the oil flow!" But actually restarting shut-in facilities and reorienting tankers will take time, while the entire episode has raised caution among shippers.
But markets remain optimistic. Brent crude fell over 4% on news of the U.S.-Iran deal, trading at around $83 per barrel, its lowest level since early March. In Asia, equity markets in big net energy importers certainly welcomed the announcement, with Japan's Nikkei and South Korea's KOSPI both rising by 5%.
Stateside, Wall Street futures were up over 1% before the bell, while in Europe, the STOXX 600 hit a record high.
The prospect of the strait reopening should ease inflation expectations and temper rate-hike bets, which have surged as the three-month-old conflict has led to energy-driven price rises in economies around the world. Most recently, U.S. headline CPI topped 4% in May.
U.S. Treasury yields fell on Monday, with the 10-year yield touching a one-month low, helping drag the dollar lower.
This news is coming ahead of a big week for central banks. The possibility that the energy squeeze will now ease could strengthen the hand of dovish policymakers - potentially including new Federal Reserve Chair Kevin Warsh.
The Fed is set to meet on Wednesday in what will be the new chair's debut meeting, where policymakers are expected to leave rates unchanged at 3.50%-3.75%. The messaging at the meeting will be scrutinized as investors seek to determine how Warsh will steer the central bank now that he's at the helm.
Warsh is widely seen as favouring loosening policy in the near term, while an increasing number of FOMC members have recently pushed back against the "easing bias" in the Fed's policy language. News of the preliminary U.S.-Iran deal will no doubt impact that debate, though a series of robust U.S. jobs prints, most recently May's non-farm payrolls, is likely to keep the heat on.
Up first on this week's central bank docket, though, is the Bank of Japan, which will meet on Tuesday and is expected to raise rates to 1%, a 31-year high.
Meanwhile, the Bank of England is expected to keep rates unchanged when it meets on Thursday.
Moving back to equities, investors will watch Elon Musk’s SpaceX closely this week to see how the recently listed rocket maker trades after its 19% rise on Friday.
Also on the slate for this week is the G7 summit, which kicked off in France today, and May inflation releases from the UK and euro zone. In the UK, Thursday will also bring an important by-election that could set up a head-to-head leadership contest between Prime Minister Keir Starmer and Greater Manchester mayor Andy Burnham.
