A two-week ceasefire agreement between the U.S. and Iran, which includes the reopening of the Strait of Hormuz, triggered a significant rally in Asian equities and a sharp decline in oil prices on Wednesday [1][2]. Japan’s Nikkei 225 soared by 2,878.86 points, or 5.39%, closing at 56,308.42, while Australia’s S&P/ASX 200 rose 2.6% to 8,951.80, South Korea’s Kospi jumped 7.1% to 5,884.55, Hong Kong’s Hang Seng climbed 3.1% to 25,901.61, and the Shanghai Composite gained 2.5% to 3,988.38 [1].
Oil markets saw dramatic moves, with benchmark U.S. crude dropping $18.23 to $94.72 a barrel and Brent crude falling $16.43 to $92.84 a barrel, representing a 13.5% slide for Brent and nearly 15% for U.S. West Texas Intermediate, both falling below $100 a barrel [1][2]. Natural gas futures also declined by 20% [1]. The ceasefire agreement stipulates that President Donald Trump will halt attacks on Iranian infrastructure, while Iran will allow safe passage of ships through the Strait of Hormuz under military management for the next two weeks, according to Iranian Foreign Minister Abbas Araghchi [1][2].
U.S. Treasury yields plunged as investors flocked to bonds, with the 10-year Treasury yield falling more than 10 basis points to 4.2399% [2]. The 2-year Treasury note yield dropped 11 basis points to 3.7193%, and the 30-year yield fell 7 basis points to 4.8482% [2]. The yield on the 10-year Treasury also eased to 4.24% from 4.30% earlier Tuesday, according to another report [1]. The decline in yields reflects easing concerns over inflationary pressures that had been stoked by the five-week conflict [2].
On Wall Street, the S&P 500 erased all its losses and ended with a modest gain of 0.1%, the Dow Jones Industrial Average dipped 85 points or 0.2%, and the Nasdaq composite added 0.1% [1]. In currency markets, the U.S. dollar weakened to 158.10 Japanese yen from 159.52 yen, and the euro strengthened to $1.1700 from $1.1597 [1].
Analysts expressed cautious optimism, noting that the ceasefire is only two weeks long and that markets will closely monitor whether shipping through the Strait of Hormuz normalizes and if the truce leads to a more durable peace agreement [1]. Tim Waterer, chief market analyst at KCM Trade, described the mood as one of 'cautious optimism rather than outright celebration' [1]. Takashi Hiroki, chief strategist at MONEX, warned that 'it is still too early to tell, because, as you know, after all, it is Trump' [1]. Investors are also awaiting the release of the Federal Open Market Committee's March meeting minutes and upcoming U.S. inflation data, which could further influence market direction [2].
CONCLUSION
The U.S.-Iran ceasefire and reopening of the Strait of Hormuz sparked a strong rally in global equities and a sharp drop in oil prices, with investors showing cautious optimism about the truce's durability. Bond yields fell as inflation fears eased, but analysts warn that the situation remains fluid and markets will closely watch for further developments. Upcoming U.S. economic data and central bank signals may further shape market sentiment in the days ahead.
