Government bonds continued their selloff on Monday on fears that the impasse over the opening of the Strait of Hormuz will keep boosting energy costs, stoking inflation. Some economists predict a global recession unless oil flows restart from the Persian Gulf.
The impasse triggered another outburst from U.S. President Donald Trump. On Sunday, the day after he returned from his visit to Beijing, he used a social media post to threaten Iran once again. “For Iran, the Clock is Ticking and they better get moving, FAST, or there won’t be anything left of them,” he wrote.
Mr. Trump is to meet his top national security advisers on Tuesday to discuss options for renewed military attacks on Iran, according to various reports.
On Monday, 10-year German bond yields hit 3.193 per cent, its highest since 2011, according to data from London Stock Exchange Group. Ten-year British government bond yields hit their highest since 2008. The yield on 10-year U.S. Treasuries went to 4.63 per cent, the highest since January, 2025.

The U.S. and Israel began attacking Iran on Feb. 28. The Strait of Hormuz, through which one-fifth of the world’s oil and liquefied natural gas passes, has been largely closed since then. Soaring pump prices have sent Mr. Trump’s approval ratings plummeting. A new New York Times/Siena poll put the rating at 37 per cent – a new low for the president’s second term in the White House.
A ceasefire has been in place since April 8.
The possibility of renewed attacks on Iran sent oil prices up on Monday morning. In early afternoon trading in London, Brent crude, the international benchmark, was up 1.3 per cent, to US$111 a barrel – an increase of 69 per cent over one year – before giving up its gains later in the afternoon. Before the war started, Brent was trading at less than US$70.

Inflation rates have been rising, pushing up the cost of debt, including mortgage rates. The U.S. Treasury last week issued bonds with a yield of 5 per cent for the first time since 2007.
Economists think the inflation surge will continue as high energy costs ripple through economies. The closure of Hormuz is also pushing up the price of other commodities, including nitrogen-based fertilizers, sulphur, methanol, aluminum and helium, which plays a crucial role in the production of semiconductors and the operation of MRI scanners.
On Friday, the Survey of Professional Forecasters, a group of top economists polled each quarter by the Federal Reserve Bank of Philadelphia, predicted that consumer price inflation would hit 6 per cent in the first quarter of next year. The survey’s earlier forecast, made just before the start of the war, had put inflation gain at just 2.7 per cent.
Mortgage rates, which are usually priced off bond yields, are climbing, adding to Mr. Trump’s popularity woes as the Republican party heads into the Congressional midterm elections in November. In the U.S., most homeowners have mortgages, pushing the cost-of-living crisis to the top of the political agenda.

For a 30-year mortgage in the U.S., the rate has climbed to 6.36 per cent, which is higher than they were in September, 2025, when the Federal Reserve began cutting rates. In Germany, rates have climbed by about 0.3 percentage points. In Britain, the increase has been even greater, with two-year fixed mortgage rates at 5.1 per cent in April, up from just under 4 per cent at the end of February. The sharp rise raises homeowners’ mortgage financing costs by more than a quarter.
Economists are no longer ruling out a recession in some countries, or even globally.
In an interview with The Globe and Mail on Monday, Karim Abadir, an economist at Imperial College London and the American University of Cairo, said he expects a recession in the medium term, since the Hormuz crisis remains intact.
“Yes, I am expecting a recession,” he said. “Western financial markets, especially in the U.S., have been overly optimistic about a resolution of the Iran conflict. The mentality of retail investors ‘buying the dip’ has been masking deeper unease by professionals who have been reducing their positions.”
Nouriel Roubini, the economist who called the financial crisis of 2007 and 2008, said in a recent comment article for Project Syndicate that investors seem to be overly optimistic that a U.S.-Iran peace deal is imminent. He said that if fighting were to resume, and Iran were to retaliate by tightening its grip on Hormuz and inflicting more damage on Gulf oil and gas sites, “oil prices would spike closer to [or even above], US$200 per barrel, and we could be looking at 1970s-style stagflation, a global recession and a bear market for equities.”
On Monday, tensions remained high in the Gulf region.
A drone strike triggered a fire at a nuclear power plant in the United Arab Emirates, though the plant remained safe, and Saudi Arabia said it had intercepted three drones that came from Iraqi airspace.
The UAE did not know immediately whether the drones came from Iran or one of its proxies. They weapons hit an electrical generator just outside the inner perimeter of the Barakah nuclear power plant, according to the Abu Dhabi Media Office.
