US-Iran Tensions Keep Oil Prices Elevated and Pressure Asian Shares

Market Reactions and Economic Impacts

Asian Stock Markets Respond to Geopolitical Tensions

SINGAPORE, May 5 (Reuters) - Stocks in Asia slid on Tuesday while oil prices eased but remained well above $100 a barrel, as the U.S. and Iran continue to work towards a truce while at the same time trading blows over the Strait of Hormuz.

Traders also had their eyes on the yen after the Japanese currency briefly jumped in the previous session, stoking speculation of another round of intervention from Tokyo.

MSCI's broadest index of Asia-Pacific shares outside Japan was down 0.3%. Shares in Australia fell 0.4% in thinned Asia trade, while markets in Japan and South Korea were closed for a holiday.

Nasdaq futures and S&P 500 futures edged down about 0.1% each, while EUROSTOXX 50 futures lost 0.2% and FTSE futures fell 0.75%.

US-Iran Conflict in the Gulf

The U.S. and Iran launched new attacks in the Gulf on Monday as they wrestled for control over the Strait of Hormuz with duelling maritime blockades, not long after U.S. President Donald Trump launched a new effort to get stranded tankers and other ships through the vital energy-trade chokepoint.

Maersk said the Alliance Fairfax, a U.S.-flagged vehicle carrier operated by its Farrell Lines subsidiary, exited the Gulf via the Strait of Hormuz accompanied by U.S. military assets on Monday.

Still, the renewed hostilities jolted markets and served as a stark reminder that the war in the Middle East was far from over.

Market Analyst Perspectives

"We started yesterday with high hopes that operation 'Project Freedom' would be, I guess, a success on the ground, that it was being pitched as more of a humanitarian effort," said Tony Sycamore, a market analyst at IG.

"But as we saw, the Iranians weren't taking that bait at all... It really signifies that the stalemate remains in place, it's been a very shaky start."

Oil Prices and Supply Concerns

In oil markets, Brent crude futures fell 0.5% to $113.85 a barrel while U.S. crude slid 1.3% to $105.03, having jumped in the previous session on heightened worries about supply disruption.

Corporate Earnings and Economic Data

Geopolitics aside, investors were also bracing for earnings reports this week, with Advanced Micro Devices and Pfizer among those set to release results later in the day.

Data from S&P Global Market Intelligence showed 83% of S&P 500 companies that have already reported have beaten EPS estimates and 78.2% of them have beaten revenue estimates.

Technology Sector Leads Growth

"With no signs of slowing down, AI-driven spending will likely continue to do the heavy lifting for S&P 500 earnings growth, led by the technology sector," said Jeff Buchbinder, chief equity strategist at LPL Financial.

Currency Markets and Central Bank Actions

Yen Intervention Watch

The yen was last steady at 157.22 per dollar, after Monday's short-lived surge that saw the Japanese currency touch an intraday high of 155.69.

Japanese Finance Minister Satsuki Katayama on Monday spoke out about against speculative trading in foreign exchange, leaving market participants on alert for further intervention after sources told Reuters Tokyo intervened to prop up its ailing currency on Thursday.

Abbas Keshvani, Asia Macro Strategist at RBC Capital Markets, said authorities could intervene again if dollar/yen continues to test 160 which they have historically defended, noting that in 2022, Tokyo "fired three volleys of intervention in a few weeks".

"We suspect intervention will merely act as a lid on USD/JPY, not a catalyst for protracted yen strength," he said.

Other Currency Movements

In other currencies, the Australian dollar eased 0.06% to $0.7163 ahead of the Reserve Bank of Australia's interest rate decision later in the day, where a hike is widely expected.

The U.S. dollar meanwhile firmed on safe-haven demand.

Federal Reserve Policy Outlook

The outlook for Federal Reserve policy could be budged by a raft of data this week which includes April's nonfarm payrolls report on Friday.

Expectations are for the U.S. economy to have added 62,000 jobs following March's outsized 178,000 gain, though problems with seasonal adjustment make for much uncertainty.

Markets currently expect the Fed to leave its policy interest rate on hold this year, owing to inflationary pressure from the global energy shock.
