Asian shares wobble as oil jumps on renewed Gulf hostilities

By Stella Qiu

SYDNEY, July 9 (Reuters) - Asian shares wobbled on Thursday as a rally in semiconductors lost momentum, while oil prices surged as a resumption of hostilities in the Gulf reignited inflation fears and hammered bonds.

Oil prices rose for a third straight session as the U.S. military completed another round of strikes against Iran. President Donald Trump said on Wednesday the interim agreement with Iran to end the war was "over", although he later said he did not expect a return to a full-fledged war, helping soothe concerns.

Brent crude futures rose 1% to $78.85 a barrel and were up 9% this week to cross above $80 a barrel for the first time since June 22.

That knocked global bond markets and boosted bets that the Federal Reserve will have to raise interest rates this year to tame inflation, with Fed funds futures now implying 38 basis points of policy tightening this year, back to where they were a week ago.

Wall Street initially fell on Trump's comments but climbed off session lows, with the Nasdaq eking out a small gain of 0.2%. Chip giant Nvidia rallied 3.6% after media reports that China plans to allow its top AI firms to buy a limited number of the company's H200 chips.

European bourses looked set for a higher open, with pan-region stock futures up 1%. Wall Street futures were about 0.2% higher.

MSCI’s broadest index of Asia-Pacific shares outside Japan reversed earlier gains and were last off 0.5% as the rally in chipmakers faltered, while Japan’s Nikkei climbed 1.3% to break a three-day losing streak.  

South Korea’s KOSPI rallied as much as 4% before turning 1% lower as gains in Samsung and SK Hynix faded.

"At this stage, the market still appears skewed towards the view that the (Iran) conflict ultimately de-escalates, and negotiations resume around the memorandum of understanding," said Chris Weston, head of research at Pepperstone.  

"Nevertheless, traders understand the need to remain open-minded. The situation remains highly fluid, and conviction around timing is exceptionally difficult."

Minutes released by the Fed showed concern about mounting inflation among policymakers. A few participants said there was already a case to raise borrowing costs, before ultimately agreeing with their colleagues to hold rates steady last month. 

The global bond rout deepened in Asia. The yield on 10-year Japanese government bonds hit 2.9%, the highest since 1996, while Australia's 10-year government bond yields scaled a one-month peak of 4.933%.

The benchmark 10-year U.S. Treasury yields climbed 1 basis point to 4.5772% on Thursday after rising 4 bps overnight. They are up 10 bps so far this week.

The reaction in the currency markets was rather muted, with the dollar failing to hold on to its yield support and last down 0.1% to 162.41 yen. That was not far from 40-year peaks of 162.84 as speculators remain wary of Japanese intervention.

The euro edged up 0.1% to $1.1426, while sterling <GBP=> held at $1.3396, just below a three-week peak of $1.341.
