Despite the Expected Oversupply, Prices Remain High: The Market Buys the Probability of War - The Mechanism Behind Oil Movement Amid U.S.-Iran Tensions

The crude oil market does not move solely based on supply and demand figures. Sometimes, it moves based on "probability." Before the weekend, what traders fear most is the uncertainty of "not knowing what will happen after the weekend." This time, the significant jump in crude oil prices was precisely due to the concentration of this "weekend risk."

1. What Happened: "No Decisive Breakthrough" Moves the Market, Not a Breakdown

According to reports, while there were signs of progress in the U.S.-Iran talks, they did not reach a decisive breakthrough, raising awareness of possible military actions. As a result, crude oil futures rose, with Brent moving into the low $70s and WTI extending into the high $60s.

The key point is that the scenario where "risk disappears with an agreement" was postponed, rather than a "complete breakdown." Entering the weekend without an agreement in sight makes it easier for hedging (insurance) purchases to occur. The market is buying not the news itself, but the "distribution" suggested by the news.

2. The Nature of Rising Oil Prices: Insurance Premiums Called Geopolitical Premiums

In the market, people imagine what could happen if a conflict becomes a reality and incorporate the "insurance premium" that matches those losses into the price. A symbolic example is the Strait of Hormuz. As one of the world's major energy choke points, if navigation becomes unstable, it would not only affect physical supply but also cause a chain reaction affecting insurance, transportation, and inventory strategies.

Some reports suggest that such concerns are being added to the price, and in some cases, significant upward swings are also being discussed.

 

However, the market prices not only "whether it will happen" but also "to what extent and for how long" it will happen. Therefore, the same tension can sometimes end in a "momentary spike" or remain "high."

3. Why the Upside Is Not Unlimited: The Tug of War on the Supply Side

On the other hand, there are also brakes visible on this rise in crude oil prices. As highlighted in the summary by Seeking Alpha, the supply decisions by Saudi Arabia and OPEC+ could leave a sense of "excess," and the fact that supply and demand have not fully tightened makes it easy for the upside to be weighed down.

 

Furthermore, if expectations for OPEC+ to resume production increase, even if a "geopolitical premium" is added, it will be difficult for a "supply-demand tight premium" to be stacked on top. The market looks at not only "danger" but also "leeway."

Additionally, from the perspective of banks, there is a dual view that "even a small supply disruption can offset the excess outlook," while "if there is no major disruption, there is room for a decline."

 

In other words, the current rise is not a "one-way bullish" scenario but rather a pricing that estimates the "tail of the upside" highly.

4. Reactions on Social Media: Different Risks Viewed from the Same News

On social media (especially X, where many market participants post), reactions were divided into several layers.

4-1. The Layer Following "Probability": Linking Odds of Conflict with Oil

Some posts highlighted the possibility (odds) of a U.S. attack, viewing the rise in oil prices as an "upward revision of probability."

For this layer, what matters is how the tone of statements from the countries involved and military movements shift the "probability distribution," with prices reflecting that.

4-2. The Tail-Focused Layer: "Even $90 Up" Cautious of a Single Breakthrough at Hormuz

Other posts, rather than focusing on the details of negotiation progress or stagnation, emphasized the "worst-case scenario if a conflict occurs," warning that Brent could significantly spike. 

This layer focuses more on the "thickness of the tail" than short-term price movements. Even a small probability with huge damage means high insurance, according to this thinking.

4-3. The "Calm" Layer: Prioritizing Supply Increases, Hedges, and Supply-Demand Realities

On the other hand, while acknowledging the price rise, there are voices emphasizing the cushion on the supply-demand side, such as U.S. production increases (shale), producer hedging, and OPEC+ policies. The reality is that the market does not rise indefinitely on "war news" alone.

4-4. The "Stocks and Macro" Layer: Rising Oil Prices as a Risk-Off Signal

There are also reactions discussing the impact of rising oil prices on risk assets or the ripple effects on stock indices and regional markets (such as Middle Eastern stocks). Energy is not only a "commodity" but also a "macro variable" that shakes the financial environment.

5. The Focus from Here: The "Next Move" the Market Is Watching

In the short term, the market's attention is concentrated on the following three points.

The Continuation of Diplomacy

: Whether talks continue and tensions are managed, or if statements and military actions cause probabilities to spike.

1. OPEC+ Supply Decisions
: If production increases are prioritized, the upside is likely to be restrained, whereas a cautious stance would make the geopolitical premium more effective.

2. Signs of "Actual Damage"
: Whether transportation, insurance, and export stagnation begin to accompany prices with substance rather than imagination.

Ultimately, the current rise is not a market declaring "war will happen."

The probability of "it might happen" has risen to an "unignorable probability" before the weekend
—it's a "probability buy."

And this type of market will jump if the news worsens and fall if it calms down. Whether it becomes a major trend depends on where the next report moves the "probability."
