Stocks rise despite Iran tensions, oil up, yen eases

On Tuesday, European stocks and U.S. futures experienced a rise, despite a surge in oil prices that raised doubts about resolving the U.S.-Iran conflict through diplomacy. The yen also saw a slight dip, but maintained most of its gains driven by Tokyo and Washington's joint efforts last week. Conflicting statements from both nations added to the market's uncertainty, especially following a new attack on shipping in the Strait of Hormuz, which threatened global energy flows.

Oil prices climbed by 1.4 percent, reaching $84.95 per barrel after falling 7 percent the previous day to a three-week low. European index STOXX 600 rose by 0.55 percent, with tech stocks gaining 1.7 percent. Both Nasdaq and S&P 500 futures climbed by 0.67 percent and 0.22 percent, respectively. The S&P 500 index recorded a 1.48 percent jump, nearing its all-time high of 7,620.90, while Dow Industrials hit a record high close.

MSCI's world stocks index increased marginally by 0.05 percent. Meanwhile, Japan's Nikkei gained 0.32 percent. Experts at Jefferies expressed optimism about adding risk to sectors such as tech and finance, citing growing cash reserves in the system. Federal Reserve Chairman Kevin Warsh's remarks had hinted at a slower pace of rate hikes, which bolstered market confidence.

However, concerns remained for Europe, with drought affecting Rhine shipping and declining gas inventories. The dollar climbed 0.4 percent against the yen, regaining strength following coordinated intervention by U.S. and Japanese authorities last week. The Japanese currency had become approximately 4 percent stronger against the greenback compared to levels a week ago, marking the first U.S. intervention in the Japanese foreign exchange market in 15 years.

Yet, doubts persisted about Japan's fiscal policies and the Bank of Japan's cautious approach to rate hikes, which could negatively impact the yen.
