Chip makers and tech investors such as Samsung and SoftBank plunge as potential interest rate hikes spook markets

• Larry Elliott: the global economy is muddling through. But a storm is coming

An accelerating sell-off of AI-linked shares has hit global markets, as fears over rising inflation and future interest rate hikes spooked traders already wary of the heavily indebted sector.

South Korea’s benchmark Kospi 200 index, which is heavily skewed towards the companies that make memory chips, fell more than 8% overnight to a six-month closing low, triggering circuit breakers that brought trading to a halt at various points.

Finance ministers gathering for the IMF annual meeting know the need for multilateral cooperation to deal with many crises. There is little chance of that

Not much has gone right for the global economy this year, and plenty has gone wrong. Two big regional wars are destabilising prices and supply chains everywhere. Businesses and consumers are feeling the effects of a serious energy shock. Rising inflation has made it a lot more expensive for governments to finance their debts. China and the US are at loggerheads over trade.

Yet, so far, the impact has been modest. It is something of a miracle that the finance ministers and central bank governors gathered for this year’s annual meeting of the International Monetary Fund (IMF) in Bangkok are not having to deal with a full-blown crisis. This is not like the autumn of 2008, when the meetings took place during the worst of the global banking meltdown.

Firms turning crude oil into the ‘workhorse’ fuel stand to gain most despite economic fallout from record prices

Days after Donald Trump announced a deal to import Russian diesel into the US in an effort to lower soaring pump prices, the world’s energy watchdog has warned that the global fuel shortage will drag into 2027.

Trump’s temporary sanctions reprieve was criticised for offering “too little, too late” to temper the sky high pump prices triggered by the shutdown of war-damaged refineries in the Middle East and Russia – once the world’s second-largest diesel exporter behind the US.

Analysts say fuel will take weeks to ship and quantity is too small to affect prices, while full deal is unlikely to be met given damage to Russian refineries

• Trump announces partial ceasefire but Zelenskyy says deal is ‘news to me’

Donald Trump’s deal with Vladimir Putin to temporarily lift sanctions on US imports of Russian diesel will have little “meaningful” effect on motorists and businesses in the US and overseas, energy and foreign policy analysts have predicted.

The US president infuriated Volodymyr Zelenskyy when he announced the deal on Friday, writing on Truth Social that the agreement with his Russia counterpart to supply millions of tonnes of diesel was essential to reduce fuel prices in the US, which have soared after his decision to go to war against Iran.
