On June 23, international oil prices remained under pressure. Mid-session quotes around the time of writing showed Brent and WTI crude oil experiencing slight declines, continuing the sharp pullback from the previous trading session. Market focus shifted from Middle East military risks to actual supply changes following a temporary U.S.-Iran arrangement. According to a Reuters report, two crude oil tankers, carrying a combined total of slightly less than 2 million barrels of crude, passed through the Strait of Hormuz on Monday, indicating that traffic is resuming in this critical waterway. For the oil market, whether ships can sail and whether Iranian oil can be sold have a more direct impact on short-term prices than diplomatic rhetoric.
Oil Trades First on 'The Strait Is Passable'
The immediate trigger for this round of oil price decline was the resumption of traffic through the Strait of Hormuz.
The Strait of Hormuz is one of the world's most crucial oil shipping chokepoints. Amid the earlier tense situation, the market was once worried that a shipping disruption would quickly affect Middle East crude exports, with supply risks being priced in. Now, the passage of two tankers provides traders with a clearer real-world signal: at least some crude shipments are resuming.
This is also why oil prices showed no significant rebound on June 23, following a roughly 4% drop in the previous session. Intraday quotes showed Brent holding around $77 per barrel and WTI fluctuating near $74 per barrel. The market is now pricing in the fact that "the worst-case scenario has not materialized for now."
However, prices have merely retreated, not fully returning to the pre-conflict calm state. The resumption of Strait traffic can reduce short-term panic but cannot eliminate the possibility of a deal breakdown, renewed shipping disruptions, or changes to sanction arrangements. For the crude market, the current situation is more akin to a cooling of supply disruption risks rather than a removal of Middle East risks.
The 60-Day Window Temporarily Eases Iranian Oil Sales
Another clue depressing oil prices is the window left for Iranian oil sales by the temporary U.S.-Iran arrangement.
According to the content of the U.S.-Iran memorandum of understanding disclosed by Axios, the arrangement includes a roughly 60-day window for nuclear negotiations and allows Iran to sell oil during this 60-day period. Reuters cited a senior U.S. official stating that Iran can begin selling oil and fuel immediately after the agreement is signed.
The impact on the global oil market is direct. Previously, the market worried about two things happening simultaneously: disruptions in the Strait of Hormuz and continued restrictions on Iranian supply. If the waterway is restored and restrictions on Iranian oil sales are temporarily eased, the tightest scenario on the supply side would be postponed.
But the "60 days" itself is also a constraint. It indicates that the current arrangement is still a negotiation window, not a final agreement. If Washington and Tehran cannot progress towards a more stable arrangement within the window, Iran's exports, sanction enforcement, and shipping security may all re-impact oil prices once exemptions or temporary permits expire.
Therefore, the market remains cautious about further oil price declines. The short-term sales window can dampen panic but does not guarantee a long-term restoration of Iranian exports or the sustained smooth passage of the Strait of Hormuz.
Political News Could Still Interrupt the Oil Price Decline
The current volatility in oil prices remains highly dependent on political news.
The temporary U.S.-Iran arrangement has improved short-term sentiment, but mutual trust between the two sides is not solid. Documents disclosed by Axios and Reuters reports show that the core of the deal remains buying time for subsequent nuclear talks. In other words, the current outcome is closer to "letting the oil flow first" rather than resolving long-term differences between the U.S. and Iran.
Previous tough rhetoric surrounding the Strait of Hormuz has already shown the market the sensitivity of this risk. Any new signals of military threats, shipping restrictions, or stalled negotiations could prompt crude prices to re-price risk premiums. For traders, the most important thing now is not how optimistic the statements are, but whether tanker traffic and Iranian sales can be sustained continuously.
This also explains the contradictory performance of oil prices: supply-side easing signals appear, and prices fall accordingly; but the decline hasn't completely erased previous gains because the temporary arrangement has not yet turned into a long-term guarantee.
Low SPR Levels Limit U.S. Emergency Buffer
As oil prices decline, U.S. Strategic Petroleum Reserve (SPR) levels remain at multi-year lows.
Public reports citing U.S. Energy Information Administration data stated that as of the week ending June 12, the U.S. SPR stood at approximately 340 million barrels, its lowest level since 1983. This figure is not the main cause of the current oil price drop, but it draws a risk boundary for the market: if the Strait of Hormuz faces disruptions again, negotiations break down, or commercial inventories decline simultaneously, the strategic buffer the U.S. can deploy is thinner than in the past.
A Reuters survey also showed the market expects U.S. crude, distillate, and gasoline inventories likely fell last week. If subsequent inventory data confirms declines, the downside for oil prices could be limited, especially while Middle East risks have not been fully resolved.
The clearest short-term logic for the oil market right now is that the resumption of Strait of Hormuz traffic and the Iranian oil sales window have depressed supply panic. However, the 60-day negotiation deadline, the lack of U.S.-Iran trust, and low U.S. strategic reserve levels all make it difficult for the market to interpret this round of oil price decline as a complete risk clearing. Any fresh disturbance on either the shipping or negotiation front could still prompt a swift reaction in oil prices.
