Introduction
Since 2025, the global oil market has been undergoing a profound structural adjustment. On one hand, the historically tense US-Iran relationship has seen a turning point, with substantive progress in peace negotiations gradually restoring normalcy to the Strait of Hormuz, the world's most critical oil transport chokepoint. On the other hand, after months of production quota disputes, the OPEC+ alliance finally agreed to increase daily production by 188,000 barrels starting from August. The combined resonance of these two forces has sharply heightened market concerns about future oil supply surplus, putting downward pressure on international oil prices, with Brent crude dropping over 10% from its year highs. This series of changes not only reflects the fading of geopolitical risk premiums but also reveals that global energy supply and demand are moving toward a new equilibrium. This article will conduct an in-depth analysis around geopolitical easing, OPEC+ production increase decisions, oil price transmission mechanisms, and potential future variables, aiming to present readers with a complete and three-dimensional picture of the oil market.
1. US-Iran Reconciliation and the Strait of Hormuz Returns to Calm: Systematic Easing of Geopolitical Risk
The Strait of Hormuz, as the only waterway connecting the Persian Gulf to the Indian Ocean, carries approximately 20 million barrels of crude oil and refined products daily, accounting for nearly one-third of global oil trade. For years, the standoff between Iran and the US has been a sword hanging over the strait. Whether it was Iran repeatedly threatening to block the strait or the US sending carrier strike groups as a deterrent, each escalation triggered violent oil market fluctuations. However, since the spring of 2025, the US and Iran have restarted nuclear deal negotiations with third-party mediation, gradually expanding to regional security cooperation issues. To date, negotiations have achieved substantive breakthroughs: the US agreed to lift some sanctions on Iranian oil exports, while Iran committed to limiting nuclear activities and ensuring strait navigation safety.
The significance of this shift is multi-dimensional. First, the most direct effect is the rapid evaporation of risk premiums. Previously, the market had priced in about $5-8 per barrel of geopolitical risk; with the strait fully normalized, this premium has been nearly entirely squeezed out. Second, the expectation of Iran's crude oil legally returning to international markets further strengthens the certainty of supply growth. Iran's daily oil exports have already recovered to about 1.8 million barrels from the low point during sanctions; if fully lifted, it could release about 1 million barrels per day of additional supply in the short term. Third, neighboring producers like Iraq, Kuwait, and the UAE, which maintained high inventory strategies due to geopolitical uncertainty, are beginning to loosen, with some crude stocks gradually released to the spot market.
At a deeper level, the US-Iran reconciliation has also changed the power balance in the Middle East. Gulf states like Saudi Arabia and the UAE no longer need to maintain high oil price demands under the pressure of "choosing sides," instead focusing more on their own economic transformation and production strategy rationalization. This softening of the geopolitical landscape creates a more relaxed environment for coordination within OPEC+ and weakens the "Iran threat" that has long served as a basis for oil price support.
2. OPEC+ Production Increase Decision and Global Supply-Demand Imbalance Concerns: From 'Control Production to Support Prices' to 'Fight for Market Share'
Simultaneously with the US-Iran negotiations making progress, the game over production policy within the OPEC+ alliance has also been heating up. At the June 2025 ministerial meeting, due to poor compliance by some members and downward adjustments to demand forecasts, the alliance was once deadlocked. Eventually, at a special meeting in July, OPEC+ reached a compromise: starting from August, the joint production cut will be further reduced by 188,000 barrels per day on the existing basis, effectively increasing the total production increase from the originally planned 225,000 bpd to 413,000 bpd. This means the actual production cut by the reduction alliance will shrink from about 5.86 million bpd to about 5.67 million bpd.
Behind this decision are multiple considerations. On one hand, core producers like Saudi Arabia and Russia want to respond to calls from consumer countries like the US for "production increases" to avoid accelerating the global energy transition due to excessively high oil prices. On the other hand, some members (such as Iraq, Nigeria) have long been overproducing, and the need for transparency in production compliance forces the alliance to relax caps. More critically, with the potential return of Iran and accelerating US shale production, OPEC+ feels the urgency that "if we don't increase production actively, market share will be eaten by others." In fact, in the first half of 2025, global oil supply already had a surplus of about 300,000 bpd, and the increase after August will further expand the surplus to over 500,000 bpd.
From a supply-demand fundamental perspective, although the global economy is showing a moderate recovery in 2025, the growth momentum of oil demand has clearly weakened. The latest report from the International Energy Agency (IEA) lowered its 2025 global oil demand growth forecast to 1.2 million bpd, a reduction of 200,000 bpd from the beginning of the year. Major drag factors include: the penetration rate of new energy vehicles in China exceeding 50% squeezing gasoline consumption, weak manufacturing in Europe leading to reduced diesel demand, and rapid expansion of alternative energy in emerging markets like India and Brazil. Against this backdrop, any production increase by OPEC+ will quickly convert into inventory accumulation, thus putting trend pressure on oil prices.
3. Internal Logic of Oil Price Pressure and Market Expectations: From Structural Support to Cyclical Decline
The combined effect of US-Iran negotiations and OPEC+ production increase is reflected in futures markets as a rapid contraction of long positions and a downward shift in order placement. As of mid-July, non-commercial net long positions in Brent crude futures had decreased by about 35% from the April high, while WTI crude hit a yearly low, falling to around $68 per barrel at one point. The price decline is not a simple linear extrapolation; it embodies multiple changes in market logic.
First, "scarcity expectations" have been completely replaced by "abundance expectations." Over the past two years, the market has been constantly worried about supply disruptions due to geopolitical conflicts and capacity bottlenecks from underinvestment. This "scarcity narrative" supported oil prices above $80 for a long time. Now, with the restoration of the Strait of Hormuz channel, active production increases by OPEC+, stabilization of US shale rig counts, and the strengthening of expectations for Iran's return, the market has begun to believe that global oil supply will remain ample or even surplus over the next two years. The reversal of this expectation has a particularly significant effect on depressing the forward curve; Brent futures for delivery in 2026 have fallen below $62 per barrel, suggesting that back-month prices are losing support.
Second, transmission pressure from refinery margins and product markets has increased. The oil price decline has not brought joy to the downstream; on the contrary, due to weak demand, global refinery comprehensive margins have fallen from seasonal highs to below the five-year average. Diesel and naphtha cracking margins in Asia have fallen to near breakeven levels, while European refinery utilization rates have been forced down. This means refiners are less willing to buy crude, further intensifying spot market selling pressure. When crude supply grows faster than refining capacity, passive inventory accumulation creates a negative feedback loop.
Third, the trend of accelerating liquidity withdrawal. A stronger US dollar and manufacturing PMIs in many countries falling below the 50 threshold for three consecutive months have led to overall net outflows from commodity markets, with oil, as the highest-weight commodity, bearing the brunt. Institutional investors like macro hedge funds and CTAs are shifting from long to neutral or even bearish positions, quickly removing the market's "safety cushion." This non-fundamental capital withdrawal amplifies the downward fluctuation range of oil prices in the short term.
4. Future Outlook and Potential Variables: A Game Space with Both Risks and Opportunities
Despite strong downward pressure on oil prices at present, the future path is not a one-way linear "free fall." The market still needs to be alert to several potential variables that could trigger rebounds or reversals.
First, the full implementation of the US-Iran agreement still holds uncertainties. Although the negotiation framework has been established, differences remain over details such as nuclear facility dismantling and sanctions scope. The stance of regional powers like Israel could also cause twists in implementation. Any breakdown or "backtracking" in negotiations would reignite geopolitical risk premiums, pushing oil prices up in a short-lived pulse.
Second, OPEC+ production policy is not monolithic. Saudi Arabia, as the "axis of cuts," has always advocated for "preemptive" market stabilization. If oil prices fall further below $65, it is not impossible that Saudi Arabia will join with Russia to convene an emergency meeting to restart another round of cuts. Additionally, demands from some members (such as the UAE) for higher production shares have not been fully met, and internal conflicts could erupt in the future, disrupting the pace of production increases.
Third, there may be upside factors on the global demand side. The US economy is showing resilience under the AI and reindustrialization wave, and summer driving season gasoline consumption data has not yet been fully released. Although China's new energy vehicle penetration rate is rising, its total crude imports remain positive, and reserve injection demand may be reactivated when oil prices decline. If these demands exceed expectations, they will offset some of the supply surplus pressure.
Finally, the disturbance from financial market sentiment and the US dollar trend cannot be ignored. The repeated shifts in Fed rate cut expectations, the risk of a pullback from global equity index highs, and other macro events could trigger linked volatility in oil markets. When investors switch from "risk-off" mode to "risk-on" mode, commodities often benefit first. Therefore, there is strong technical support for oil prices in the $65-75 range, and the probability of a short-term break below this range is not high.
Conclusion
In summary, the progress of US-Iran peace negotiations and the normalization of Strait of Hormuz shipping mark the shift of the global oil market from "geopolitical premium dominated" to "fundamentals pricing." OPEC+'s accelerated production increase under the pressure to fight for market share, combined with slowing demand growth, has made global oil supply surplus concerns a market consensus, putting downward pressure on oil prices. However, this round of decline is not a disorderly collapse but a rational rebalancing under the combined action of geopolitical easing, policy games, and macro expectations. The oil price trajectory in the coming months will depend on: the timeline for Iran's institutional return to exports, whether OPEC+ will adjust production strategy again, and whether the global economy has an unexpected downturn. Investors should closely monitor changes in supply-demand data and geopolitical events, maintaining vigilance for potential rebound opportunities amid a bearish sentiment trend. Only by doing so can they make prudent and forward-looking decisions in the complex interplay of longs and shorts.
