Asian shares experienced gains on Wednesday, while oil prices remained elevated as markets sought indications regarding the potential extension of a fragile truce between the United States and Iran.
Brent crude traded close to $100 per barrel, and the U.S. dollar held onto gains from the previous session after Iran accused the U.S. of breaching a ceasefire agreement. The New Zealand dollar declined ahead of an anticipated decision by the central bank to maintain its current interest rate.
Japan’s Nikkei index surged to a record high, buoyed by optimism surrounding artificial intelligence following all-time highs on Wall Street and after a U.S. holiday.
Despite the positive momentum, market sentiment appeared fragile as negotiations for a durable cessation of the three-month-long conflict, which has significantly impacted energy markets, continued. Analysts were keenly observing commentary from central bankers regarding the implications of the crisis on inflation and interest rate outlooks.
“The markets are just waiting for something tangible now when it comes to a deal between the U.S. and Iran,” remarked Kyle Rodda, senior financial market analyst at Capital.com. He noted that “a lot of good news is priced in, leaving room for disappointment if something comprehensive isn’t announced.” The MSCI index encompassing Asia-Pacific shares outside Japan climbed 1.2 percent, while the Nikkei rose 1.8 percent.
The dollar index, which assesses the strength of the U.S. dollar against a basket of currencies, remained relatively stable at 99.09 after a gain of 0.15 percent in the preceding session. The euro increased by 0.09 percent to $1.1638, and the Japanese yen strengthened by 0.05 percent to 159.19 per dollar.
Iran’s Foreign Ministry characterized U.S. strikes in the southern Hormozgan province as a “gross violation” of the ceasefire, while the U.S. maintained that its actions were defensive. U.S. Secretary of State Marco Rubio indicated that a resolution with Tehran could take “a few days.” Meanwhile, Iran’s Tasnim news agency reported that Tehran was seeking the release of $24 billion in funds that remain frozen overseas.
U.S. crude oil prices declined by 0.89 percent to $93.05 a barrel, while Brent crude fell by 0.52 percent to $99.06, following a nearly 4 percent increase in the prior session.
The Reserve Bank of New Zealand is expected to keep its benchmark interest rate steady at 2.25 percent. In Australia, market attention is focused on the release of consumer price data for April.
During a meeting in Tokyo, Bank of Japan Governor Kazuo Ueda stated that supply shocks were significant concerns. European Central Bank board member Isabel Schnabel advocated for an interest rate increase in June, even if a deal is reached between the U.S. and Iran.
Spot gold prices increased by 0.36 percent to $4,522.14 per ounce, while copper rose by 0.46 percent to $13,686.50 per metric ton. In the cryptocurrency market, Bitcoin dipped by 0.18 percent to $75,883.90, and Ether remained approximately stable at $2,075.39.
