Crude Oil Prices Vulnerable: Brent Crude Near $78, US WTI Above $74; Is All Well In US-Iran Peace Agreement?

Crude oil prices are vulnerable and volatile. Since the US and Iran have once again signaled progress on a forever peace agreement, crude oil prices have crashed sharply by 19% to 21% in the past 30 days. On Tuesday, crude oil traded cautiously and deep in the red. If oil continues to fall, the energy crisis and inflationary pressures could ease further.

At the time of writing, US WTI Crude Oil reclaimed the $74 per barrel mark after falling by 4% in the early hours of June 23, 2026. Brent Crude also recovered to near $78 per barrel after dropping by nearly 3.5%.

Both US WTI and Brent Crude held a volatile tone, after President Donald Trump has issued a new warnings to Iran.

Trump told reporters, if Iran does not complies with the peace agreement or if "they're not behaving. I will do what I have to do."

The US-Iran peace talks are at the heart of attention for global market, which is expected to ease geopolitical tensions and curb global energy crisis.

According to Trading Economics report, investors assessed signs of initial progress in ongoing peace negotiations between the US and Iran in Switzerland. In a key development, Washington granted Iran a 60-day license to sell oil on international markets, raising expectations of a quicker recovery in global supply. Traffic through the Strait of Hormuz has also picked up, with producers including Kuwait and the United Arab Emirates finding alternative routes to export energy, while Iran shipped more than 30 million barrels over the past week.

However, report also said, Iran's nuclear program remains a major point of contention after Vice President JD Vance said Tehran had agreed to admit nuclear inspectors, a claim Iranian officials have denied.

Trump further told reporters, "Oh, their navy is gone. Their air force is gone. Their leaders are all dead. Their whole country is a mess. Their economy is shot." He added that four months ago, Iran had a navy, 159 ships to be exact. Now, it's gone. He said, "The whole navy is gone. Their 250 airplanes, all gone. Their anti-aircraft is gone. Their radar is gone."

Amidst Trump's latest statement, there is visible divergence between USA and Iran despite their first round of talks in Switzerland this Sunday.

US Vice President JD Vance has warned Iran that the release of their frozen assets would decide the fate of peace negotiations. Iran has asserted that US already agreed to ease restrictions and allowed to release some sanctioned assets.

However, Vance has also stated that discussions are undergoing with the International Atomic Energy Agency (IAEA) to inspect Iran's nuclear regions. Iran has retorted that it will not allow nuclear inspectors in their country. Hence, the tensions remain high and fragile between US and Iran.

A note by UBS pointed out that so far, so good-but hope is not certainty. No treaty text has been published so far, and it is unclear how much agreement there is between the warring parties on the key points of dispute.

This raises several questions: How durable is the de-escalation? Which sanctions could actually be eased? Which frozen assets will Iran receive back, and when? And how robust is an agreement if the most difficult issues-from Iran's nuclear program to the regional security order-are to be negotiated only over the coming 60 days? These uncertainties partly explain why gold traded higher alongside equities: Markets are pricing in better prospects, but not yet lasting peace, as per UBS.

What Does Falling Crude Oil Prices Mean For The Global Market?

As per UBS, falling oil prices ease inflation expectations, reduce pressure on central banks, and support risky assets. This could also broaden the equity rally through year-end; alongside technology stocks, more cyclical market segments could increasingly benefit from still-robust growth, fiscal policy stimulus, and less restrictive monetary policy prospects.

However, for bonds, the picture is more mixed: Lower inflation fears help, but concerns about the sustainability of government debt are likely to continue preoccupying markets.

What should investors do?

In UBS' opinion, for investors, this means more short-term tailwinds for risk assets, but over the medium term, it still points to an environment in which quality, diversification, and real sources of income remain crucial. Investments in alternative assets, such as the expansion of strategic infrastructure, could offer attractive opportunities for investors with room in their portfolios for illiquid investments.

"Regardless of whether we see a brief pause or a longer ceasefire in the Middle East, such assets should continue to benefit from the expansion of strategically important infrastructure," UBS' note said.
