Morning Brief, Monday 3 August

Donald Trump abruptly cancelled planned US strikes on Iran after saying negotiators had reached the parameters of a deal to end the five-month war and reopen the Strait of Hormuz. He said Iran and other Middle Eastern countries had asked him to hold off, and he claimed Israel had joined the United States in trying to complete the agreement. Tehran gave a very different account. Iran's Mehr news agency called the claim a lie, while Fars quoted a source close to nuclear talks saying the strait would stay closed while Washington maintained hostile actions.

The reversal matters because Hormuz is not a diplomatic flourish. About a fifth of global oil production normally passes through the strait, and the blockade has already forced shippers, refiners and central banks to price in a wider war. Saudi Crown Prince Mohammed bin Salman urged de-escalation before the announcement, reflecting Gulf fears that Iran could answer American or Israeli action by striking energy infrastructure across the region.

OPEC+ added to the odd picture by agreeing to raise September output targets by 188,000 barrels a day, even though war and the Hormuz closure still keep large volumes from reaching buyers. The cartel can announce barrels more easily than it can move them through a contested waterway. Castles rarely decide modern wars; choke-points do, and this one will decide how much trust is left in a truce that had little to spare (4a3fc0-bc36-4e71-838d-3c774e163aee).

Ceuta moved from emergency to aftermath after more than 50,000 people crossed from Morocco into the Spanish enclave on 30 and 31 July. Spanish officials said at least 72 people died, mostly by drowning or in crushes near the Tarajal breakwater, and more than 1,000 people received medical treatment. By Sunday, Madrid said more than 48,000 people had returned to Morocco within 48 hours, while soldiers and police guarded streets, supermarkets and the new 500-metre floating barrier off the coast.

Morocco broke three days of silence and acknowledged that 40,000 people had crossed and 11 had died on its side of the border. Rabat blamed social-media rumours, trafficking networks and misreadings of a Spanish court ruling that restricted immediate returns by sea. Spain suspects a failure, or a relaxation, of Moroccan border control made the mass entry possible, while Moroccan officials reject any deliberate passivity.

The political argument quickly outran the humanitarian one. Italy suspended Schengen travel arrangements with Spain for a month, and 22 EU governments demanded tougher external-border controls, faster returns and action against what they called pull factors. Pedro Sánchez accused partners of a selfish and illegal reaction, while Giorgia Meloni used the crisis to revive proposals for EU-funded return hubs in third countries.

The argument will shape Europe's next migration fight because Ceuta compressed every pressure point into one weekend: border policing, social-media panic, returns law, Moroccan leverage and the EU's thin habit of solidarity under stress.

Europe's summer hazards are now piling up rather than taking turns. Near Athens, two firefighting helicopters collided while battling a wildfire west of the capital, killing two crew members in one account, while broader reporting described a major blaze that destroyed more than 10,000 hectares and forced evacuations from Porto Germeno and nearby villages. Greece deployed nearly 500 firefighters, 23 aircraft and helicopters, military vehicles and foreign crews as winds gusting up to 100 km/h grounded aircraft at times.

Italy meanwhile put 25 cities under the health ministry's highest heat alert for Monday, the most this season, after Terni reached 41C and much of the Po Valley and inland centre crossed 40C. Rome activated 660 climate shelters, including free cinema screenings, because extreme heat now turns social policy into emergency infrastructure. Poland also warned of temperatures up to 38C, violent storms, hail and tropical nights that stop bodies from recovering after hot days.

The most revealing stress test came on the Danube. Hungary began the first full shutdown in the 44-year history of the Paks nuclear plant after water levels fell too low for cooling. The four reactors normally supply roughly 40-45% of national electricity, and the government prepared industrial consumption cuts as temperatures in Budapest were forecast to reach 34-42C.

The old assumption was that heat strained demand and fire strained land; this week shows climate stress can also trip the machines built to keep modern economies cool.

Japan and the United States confirmed a coordinated yen-buying intervention after the dollar had pushed above 163 yen, levels last seen in the mid-1980s. Japan's Finance Minister Satsuki Katayama said the operation countered excessive volatility and disorderly moves, while US Treasury Secretary Scott Bessent said Washington strongly supported Japan's steps to correct yen undervaluation. The dollar fell about 1% to 156.34 yen after the announcement early Monday.

The plumbing matters. Reports said the New York Federal Reserve sold euros to buy yen on the Treasury's behalf, and Bessent pointed to the Fed's FIMA Repo Facility, which lets foreign central banks raise dollar cash against Treasuries without dumping those holdings into the bond market. Japan held $1.14 trillion of Treasuries at the end of May, making any forced sale a problem for both Tokyo and Washington.

Donald Trump described the move as a gesture of friendship, with a characteristic aside about Pearl Harbor, but the intervention also signals a more transactional currency policy. A weak yen helps Japanese exporters yet punishes households through import prices, while a strong dollar complicates Trump's own trade promises. This is alliance management with a trading screen open, and markets will now test whether the two governments meant one operation or a line in the sand.

AstraZeneca has explored a combination with Bristol Myers Squibb that would create a drugmaker worth nearly $400bn, according to the Financial Times. Talks have taken place in recent months and could still produce a deal, although the report cautioned that the process may be delayed or collapse. AstraZeneca declined to comment, and Bristol Myers Squibb did not immediately respond outside regular business hours.

The numbers explain the temptation. AstraZeneca is valued at about £196bn, roughly $264bn, and Bristol Myers Squibb at about $133bn. A tie-up would rank among the largest mergers ever and would reshape the top tier of global pharmaceuticals, particularly in cancer, rare disease and cardiovascular treatments. AstraZeneca's cancer drugs generated about $25bn in 2025 sales, nearly half of its total, while cardiovascular, renal and metabolism medicines brought in about $12bn.

Pascal Soriot has already steered AstraZeneca toward the United States, where equity valuations run richer and capital markets forgive size more readily than London does. In June the company elevated its New York listing, after earlier unveiling plans for a direct US listing while keeping London. That shift stung the City because AstraZeneca is the second most valuable publicly listed company in Britain and one of the few domestic groups with genuine global scale.

The irony is tidy. A company that once resisted Pfizer's approach may now use an American partner to become bigger still, leaving Britain to celebrate a champion that increasingly prefers to grow elsewhere.
