Oil Prices Surge Amid Middle East Tensions; Asian Shares Fall

Oil prices saw a significant increase early Tuesday as fighting intensified in the Middle East, while Asian stock markets experienced declines, largely influenced by losses in artificial-intelligence related stocks.

Brent crude climbed to just over $84 a barrel, following a nearly 10% surge on Monday. U.S. benchmark crude West Texas Intermediate (WTI) rose 1.4% to $79.20 a barrel. Despite these gains, oil prices remain below their peak of nearly $120 a barrel reached during previous conflicts. Uncertainty surrounding the stability of oil supplies has grown, with both the U.S. and Iran asserting control over the Strait of Hormuz, a critical waterway for oil transport.

U.S. stock futures indicated a downward opening, with futures for the S&P 500 down 0.3%. This follows reports of further U.S. strikes on Iran and President Donald Trump's announcement of reinstating a blockade on Iran in the strait. The conflict in the region has disrupted oil tanker traffic from the Persian Gulf, contributing to rising global fuel prices.

In Asian trading, Tokyo's Nikkei 225 index lost 1% to close at 66,574.96, and South Korea's Kospi declined 3.2% to 6,589.37. The Shanghai Composite index fell 0.8% to 3,884.32, despite official data showing a 27% jump in China's exports for June, driven by strong demand for computer chips and technology fueled by the adoption of artificial intelligence.

Hong Kong's Hang Seng index saw a slight increase of 0.1% to 24,230.46, while Australia's S&P/ASX 200 shed 0.5% to 8,767.00.

On Wall Street the previous day, the S&P 500 fell 0.8%, snapping a streak of four winning weeks out of the last five. The Dow Jones Industrial Average dropped 0.3%, and the Nasdaq composite sank 1.6%. Technology stocks, particularly those involved in AI, led the decline. Micron Technology shares fell 4.4%, impacting its year-to-date gains. Nvidia, the largest company on Wall Street by market value, also fell 3.5%, exerting significant downward pressure on the S&P 500 due to its weighting in the index.

Concerns are mounting that stock valuations may have risen too high, and that demand might not be sustainable if the projected profits and productivity gains from AI do not materialize as expected.

This week, market attention will focus on corporate earnings reports for the spring quarter. Several major U.S. banks, including Bank of America, Citigroup, JPMorgan Chase, Goldman Sachs, and Wells Fargo, are scheduled to release their latest quarterly results on Tuesday.

Analysts, according to FactSet, anticipate that companies within the S&P 500 index will report an overall earnings growth of 23.6% compared to the previous year, marking the second consecutive quarter of growth exceeding 20%.

Sustained strong performance across industries will be crucial for companies to justify their recent stock price movements, which have seen indexes approach record highs despite recent volatility stemming from AI stock speculation.

An increase in oil prices could exacerbate inflation, potentially prompting the Federal Reserve and other central banks to raise interest rates. While higher rates can help curb inflation, they also tend to slow economic growth and negatively impact investment prices.

In currency markets, the U.S. dollar slipped to 162.34 Japanese yen from 162.35 yen. The euro rose slightly to $1.1391 from $1.1381.
