Il Nuovo Postiglione - Stocks climb as oil prices retreat

On Wall Street, the technology-focused Nasdaq index advanced 0.6 percent around a half hour into the session, having already closed at a record high Monday, driven by AI enthusiasm.

That boosted European stock markets after gains across most Asian equity markets.

Oil prices were down about 2.5 percent, with the international benchmark Brent North Sea crude falling below the psychological level of $100 a barrel.

"Brent crude oil fell back below $100, much to the relief of the market," said Dan Coatsworth, head of markets at AJ Bell.

"This gave a boost to interest-rate sensitive stocks including real estate and consumer cyclicals," he said.

Arne Lohmann Rasmussen, a commodities analyst with Global Risk Management, noted that "Gulf exports excluding Iran averaged 19.2 mb/d in September, equivalent to 81 percent of pre-war levels" even though Iran is still curtailing tanker traffic through the Strait of Hormuz.

But he added that "Crude exports were back to 91 percent of pre-war levels, while refined product exports were only around 60 percent" -- a supply cut that has sent fuel costs soaring.

In the UK, the average diesel price at the pump struck a record high last week, according to official data.

There remains plenty of uncertainty among traders over the Middle East crisis, which is putting pressure on central banks to raise interest rates to combat energy-fuelled inflation.

That has pushed government bond yields up to levels not seen in decades, heightening worries about ballooning debt.

Analysts say the race to build out AI data centres, servers and chips has compounded that problem, with tech titans no longer able to rely on their vast piles of cash.

Borrowing by firms including Google, Amazon and Microsoft hit around $500 billion in the nine months since January, and Goldman Sachs expects a further ramp-up in 2027, to $1.2 trillion.

"This is not something that we've seen before," said Chris Della Fave, senior vice president at the fundraising advisory firm Post Oak Group, who estimates that AI accounts for 25 percent of all corporate bond issuance -- up from four percent two years ago.

Noting the upward push in equities, David Morrison, senior market analyst at Trade Nation, said "there was a solid start to the new week yesterday as all the major US stock indices ended the session with gains," even though elevated bond yields "remain a concern".

In company news, UK online fashion giant Asos saw its share price slump more than 10 percent in London trading Tuesday after customers reportedly received a mobile notification claiming its systems had been hacked.
