Energy analysts and traders said Monday that they wouldn't be surprised if oil prices climb to as high as $200 per barrel as the sprawling Middle East crisis drags on.

It comes as the U.S. and Israeli-led war on Iran continues to disrupt oil production and shipping in the region, with traffic through the strategically vital Strait of Hormuz effectively grinding to a halt in recent weeks.

The Strait of Hormuz is a key narrow maritime corridor that connects the Persian Gulf and the Gulf of Oman. Roughly 20% of global oil and gas typically passes through it.

President Donald Trump told reporters on Monday that the names of countries that have agreed to help the U.S. protect oil tankers in the Strait of Hormuz will be announced soon, though he added that some are "less than enthusiastic."

"We have some that are really enthusiastic. They're coming already. They've already started to get there," Trump said. "We'll give you a list. Some are very enthusiastic, and some are less than enthusiastic, and I assume some will not do it. I think we have one or two that will not do it that we've been protecting for about 40 years at tens of billions of dollars."

The president had also called out those that have not expressed a willingness to participate, saying that "we strongly encourage the other nations to get involved with us and get involved quickly and with great enthusiasm."

When asked about France's participation specifically, Trump said that he thinks French President Emmanuel Macron is "going to help" reopen the Strait.

The spike in gas prices could weigh on Best Buy''s valuation, according to Loop Capital. The firm lowered its price target to $75 from $85 on Sunday.

Loop Capital maintained its buy rating on the retail stock, with its new target implying nearly 20% upside from Friday's close.

"While it is too early in our opinion to gauge the impact on consumer spending from higher gasoline prices (which we think will be dependent on how long prices remain elevated, and thus, are maintaining our current F2026 estimates), we believe the resulting overhang will place a damper on valuation," analyst Anthony Chukumba said in a note to clients.

Shares are down 6% year to date.

The United States is allowing Iranian oil tankers to transit the Strait of Hormuz, Treasury Secretary Scott Bessent told CNBC in an interview Monday.

"The Iranian ships have been getting out already, and we've let that happen to supply the rest of the world," Bessent told CNBC's Brian Sullivan.

Tanker traffic through the Strait has plunged as Iran attacks commercial ships in the Persian Gulf. But the Islamic Republic has continued to export millions of barrels of oil through the narrow sea route despite the large U.S. Navy presence in the region. Iran exports about 1.5 million barrels per day. Read more.

Shares of Upstart may have fallen too far amid the broader downturn in private credit markets, according to BTIG.

The financial firm upgraded the artificial intelligence lending marketplace to buy from neutral. Analyst Vincent Caintic's $43 price target implies a 63% upside ahead for shares of Upstart.

Caintic pointed to Upstart's plans last week to submit an application to establish an insured national bank as a postive. He added that the market didn't react to the announcement, which he found surprising because a bank charter would address what he considers to be a key downside risk of Upstart's private credit exposure.

Asia-Pacific markets traded mixed Monday as investors assess elevated oil prices and the latest developments in the escalating U.S.-Iran conflict.

Hong Kong's Hang Seng index rose 1.45% to close at 25,834.02, while the CSI 300 was flat at 4,671.56 as China's consumption and production both beat expectations on holiday spending and strong foreign demand.

Retail sales for the first two months of the year rose 2.8% from a year earlier, beating economists' forecast for a 2.5% growth, but a notable slowdown from the 4% growth in the January-February period in 2025.

Industrial output climbed 6.3%, also exceeding expectations for a 5% jump in a Reuters poll. Industrial production has been a relative bright spot in the world's second-largest economy, thanks to resilient external demand, particularly from European and Southeast Asian nations.

Japan's Nikkei 225 was down 0.13% to 53,751.15, while South Korea's Kospi added 1.14% to 5,549.85.

Australia's S&P/ASX 200 declined 0.39% to 8,583.40.

Nvidia's GTC conference kicks off on Monday, with investors turning to it for a potentially positive catalyst.

"Nvidia is moving aggressively to dominate AI inference. OpenClaw and Nvidia's NemoClaw mark the first major step into consumer-scale agentic AI," Rothschild & Co. Redburn analyst Timm Schulze-Melander wrote in note. "At next week's GTC keynote, we expect Nvidia to reveal more of its strategy for dominance of AI inference. While the market obsesses over chips, the real story is Nvidia's 'five-layer stack' designed to squeeze hyperscaler margins and lock-in the generation of agentic AI."

President Donald Trump ordered strikes Friday against Iranian military assets on Kharg Island. Trump said the strikes had left oil infrastructure unscathed. But he warned that the U.S. would consider hitting crude infrastructure on the island if Iran continued to block the critical Strait of Hormuz.
