Berliner Tageblatt - Stocks fluctuate after Wall St sell-off, crude holds losses on peace talks

While Washington and Tehran flagged progress at peace negotiations in Switzerland, traders are struggling to build on last week's rally sparked by news of a deal to end the Middle East conflict.

Tech firms -- the main driver of a surge across world markets as investors pile into all things AI -- took a hit in Asia.

South Korean chip giants SK hynix and Samsung tumbled to drag the Kospi index down more than three percent, though it is still up more than 100 percent since the turn of the year.

Tokyo was also in the red, with tech investment titan SoftBank shedding more than seven percent and chipmaker Tokyo Electron down.

Taipei and Shanghai were down, with Hong Kong and Sydney flat. Singapore, Wellington and Manila edged up.

The tepid performance followed a sharp drop on Wall Street, where the Nasdaq sank more than one percent as market giants Amazon, Nvidia and Microsoft were sharply down.

But the main victim of the day was Elon Musk's SpaceX, which plunged more than 16 percent -- wiping hundreds of billions off its valuation -- after a record IPO and a winning trio of opening trading sessions.

The fall came as the rocket and satellite company disclosed plans for an "inaugural" bond offering of unspecified quantity.

The SpaceX disclosure arrives on the heels of a large equity round announced earlier this month by Google parent Alphabet and a data centre venture between Microsoft and Chevron, developments which underscore the hefty capital toll of the artificial intelligence drive.

Monday's selling revived worries about the wisdom of the vast sums being pumped into artificial intelligence with little sign of any returns being made soon.

Traders are also fretting over the extended valuations of some firms, with Nvidia topping $5 trillion.

"While the sector has performed exceptionally well, valuations have become stretched and the bar is now materially higher than it was a few months ago," wrote Tony Sycamore at IG.

"Questions around capital expenditure and returns on artificial intelligence spending remain unanswered. While names like Intel and Micron are hitting fresh record highs, the Magnificent Seven (of top tech firms) has lost considerable momentum in recent weeks.

"Amazon and Nvidia are trading around 12 percent below their recent peaks, while Microsoft and Meta Platforms sit not far above their March lows."

Oil prices edged up, though they remain below $80 following Monday's drop that came after the US Treasury said it was temporarily lifting sanctions on Iran to allow it to produce, sell and deliver crude oil and related products through August 21.

Maritime trackers also pointed to an uptick in tanker traffic through the Strait of Hormuz.

US Vice President JD Vance said a "very good foundation" had been laid for negotiations towards a final deal and that Iran would allow UN nuclear inspectors to return to the country.

Iranian Foreign Ministry spokesman Esmaeil Baqaei said for his part that "a very brief discussion took place regarding the nuclear issue, but there was no discussion of details".

President Donald Trump said the strait, the critical channel for much of the world's oil, is now "totally open" to shipping after Iran closed it in response to US and Israeli forces bombing the country late February.

"We're negotiating -- we'll see how that all goes -- but we have two things," Trump said. "We have an open strait and we have a country that will never have a nuclear weapon."

Attention is also on Tokyo as the yen sits just below a 40-year low against the dollar following the Federal Reserve's hawkish turn last week and concerns the Japanese central bank might not be doing enough to fight inflation.

Traders are also keeping tabs on developments after NHK and Kyodo News said Finance Minister Satsuki Katayama and US Treasury Secretary Scott Bessent had spoken about exchange rates.

Japanese authorities spent more than $70 billion last month propping up the currency as it weakened against the greenback.
