伊朗衝突如何影響油價、股市和比特幣？一條傳導鏈看懂跨資產聯動

Overview

On July 27, the military conflict between the United States and Iran, which had lasted for nearly two weeks, paused, triggering a sharp reaction across global markets. According to a CNN report, Brent crude closed at $85.87 per barrel that day, falling 11.3% in a single day, its largest drop since April 8; U.S. crude fell about 7% to $82.61. Stock markets rose in tandem, while Bitcoin briefly returned above $65,000. The market's focus on this conflict stems from its simultaneous influence on the pricing logic of three asset classes: oil prices determine inflation expectations, inflation expectations dictate central bank policy, and central bank policy shapes the liquidity environment for stocks and Bitcoin. More critically, this pause is fragile. According to a CNBC report, Iran stated it would halt attacks as long as the U.S. did not strike, but shipping traffic through the Strait of Hormuz remains far below pre-war levels. Understanding this transmission chain from the strait to the candlestick chart is a prerequisite for assessing cross-asset trends.

Key Takeaways

According to CNN, following the pause in the U.S.-Iran conflict, Brent crude closed at $85.87 on July 27, down 11.3% in a single day; U.S. crude fell about 7% to $82.61.

This pause has effectively dismantled the previous 60-day ceasefire agreement. The conflict lasted nearly two weeks, with oil prices briefly exceeding $100 per barrel at their peak.

The Strait of Hormuz carries about one-fifth of the world's crude oil and natural gas traffic. Over the weekend, fewer than 10 commercial vessels transited, compared to a normal pre-war level of about 100 per day.

Oil prices are the core transmission variable: they first impact inflation, then influence expectations for Fed rate hikes, and ultimately affect stocks and Bitcoin.

The pause news boosted risk appetite. Previously, U.S. stocks surged on the ceasefire news, with the S&P 500 closing up 2.5% in a single day.

Bitcoin rose back above $65,000 after the pause, but subsequently retreated as the Fed decision approached, indicating its inflation-hedge narrative has given way to a liquidity-driven logic.

Why the Conflict is a Common Variable Across Assets

It All Starts at the Strait of Hormuz

Understanding this transmission chain begins with geography. According to a report from the U.S. Congressional Research Service, the Strait of Hormuz is the world's most critical oil chokepoint. As the conflict persisted, oil prices briefly exceeded $100 per barrel. According to TradingEconomics records, the strait carries about 20% of global crude oil and natural gas flows, and its near-closure triggered one of the most severe supply disruptions in the oil market.

The core issue is not the warfare itself but shipping. According to a CNN report, despite the pause in conflict, fewer than 10 commercial vessels transited the Strait of Hormuz over the weekend, compared to a normal pre-war level of about 100 per day. Analysts at Deutsche Bank point out that threats from the Houthis against Saudi tankers also risk disrupting both Gulf and Red Sea export routes simultaneously. This implies that the risk premium on oil will not fully dissipate with just one pause.

Oil Prices Are the First Domino for Inflation and Policy

Oil prices are a common variable across assets because they stand at the forefront of the transmission chain. Rising oil prices fuel inflation, inflation forces central banks to maintain or even tighten monetary policy, and a tightening policy environment suppresses both stock valuations and high-volatility assets like Bitcoin. Conversely, falling oil prices ease inflation concerns, creating room for dovish central bank pivots and a rebound in risk assets.

This chain was clearly visible in the July 27 market action. According to a CNBC report, Brent crude for September delivery fell 8.7% to $88.36 per barrel, easing inflation expectations. With oil prices down, market worries about Fed rate hikes diminished, giving risk assets a breather. A single geopolitical variable, through the pivot of oil prices, simultaneously altered the pricing environment for three asset classes.

How the Three Asset Classes Reacted Respectively

Oil Prices: Quick to Rise, Quick to Fall

Oil prices react most directly and violently to geopolitical conflicts. According to a report from The Hill, at the peak of the conflict, Brent and WTI approached nearly $120 per barrel; when ceasefire signals emerged, prices rapidly retreated. Medlock, an energy expert at Rice University, noted that as long as the conflict is not completely over, the market will continue to price a "risk premium" into oil.

This kind of two-way violent fluctuation is a hallmark of oil prices. According to a CNBC report, U.S. crude fell 7.5% in a single day on July 27. Oil is both the asset that rises fastest when conflict escalates and the one that falls fastest when a pause is signaled; its volatility directly determines the magnitude of swings in inflation and policy expectations.

Stock Market: First Risk-Off, Then Risk-On Recovery

The stock market's reaction to conflict follows a "risk aversion, risk repair" rhythm. When conflict escalates, oil prices rise and inflation concerns heat up, pressuring stocks; as soon as signs of de-escalation appear, pent-up risk appetite is quickly unleashed. According to a report cited by AOL, when Trump previously announced a U.S.-Iran ceasefire, the S&P 500 closed up 2.5% in a single day, the Nasdaq Composite rose 2.8%, and the Dow Jones surged 1,325 points, marking its largest single-day percentage gain since April 2025.

But this kind of repair often has a front-running component. The same report quoted Krishna Guha, Vice Chairman of Evercore, warning that "we are not out of the woods yet; the ceasefire could collapse, and the initial inflation shock is still to come." JP Morgan's trading desk also noted that markets tend to treat a ceasefire as a de facto end to the conflict, even though the economic damage is still unfolding. The stock market rally priced in sentiment, not certainty.

Bitcoin: From "Safe Haven" to "Risk Asset"

Bitcoin's reaction is the most telling, as it reveals a shift in narrative. When the conflict eased and oil prices fell, according to a CoinPedia report, the U.S.-Iran pause caused oil prices to drop about 6%, alleviating inflation concerns and helping Bitcoin climb back above $65,000, up about 1.26% in 24 hours to $65,169.

The causal chain here is noteworthy. Bitcoin did not rise because it acted as a "digital gold" safe haven; it rose because falling oil prices eased inflation, thereby easing rate hike expectations, which ultimately benefited risk assets, including Bitcoin. In other words, in the current environment, Bitcoin's reaction to the Iran conflict follows the logic of a "risk asset," not a "safe haven" asset. It moves in the same direction as stocks and in the opposite direction of oil, which is precisely contrary to the traditional safe-haven narrative.

What This Means for Investors

For investors holding multiple asset classes, the Iran conflict provides a clear case study of cross-asset linkages. The core judgment is: do not view volatility in any single asset class in isolation, but rather determine where the shock is along the chain: "Strait shipping > Oil prices > Inflation > Policy > Risk assets."

A pragmatic framework is to distinguish between an "oil price shock" and a "safe-haven shock." When a conflict drives up oil prices, the dominant logic becomes inflation and policy, and Bitcoin is more likely to come under pressure alongside stocks; when the conflict itself triggers market panic but has not yet significantly raised oil prices, safe-haven capital may briefly flow into gold and even Bitcoin. These two scenarios have vastly different implications for portfolio positioning. According to a CNBC report, the current pause primarily benefits risk assets by lowering oil prices and easing inflation, falling into the former scenario.

Risks and Subsequent Points to Watch

The Fragile Pause Could Reverse at Any Time

The primary risk is that a pause is not a ceasefire. According to a CNN report, Trump stated the U.S. paused strikes at Iran's request but warned it would resume attacks if a new ceasefire agreement could not be reached. This pause has effectively dismantled the previous 60-day ceasefire agreement. Any new action by either side could instantly bring back the risk premium on oil, reversing the current risk-on repair.

Shipping Traffic Through the Strait of Hormuz is a Key Indicator

More than the fighting itself, shipping data is worth watching. According to a CNN report, even with the conflict paused, transit volumes through the strait remain far below pre-war levels, tanker insurance costs are high, and some shipowners continue to avoid the area. As long as shipping does not resume, actual tightness on the supply side will continue to support oil prices, and the price drop from the pause may be only temporary.

The Lagged Effect of the Inflation Shock

Even if the conflict subsides, the impact of earlier oil price increases on inflation will still emerge with a lag. According to analysis cited by AOL, experts warn that "the initial inflation shock is still to come." This means that even if the geopolitical situation eases, central banks may remain cautious due to the inflation shock that has already occurred, which could limit the upside for risk asset rebounds.

Signals to Watch

In the coming weeks, four signals are worth tracking: whether commercial vessel traffic through the Strait of Hormuz can recover, whether Brent crude can stabilize below $90, the Fed's stance on oil-driven inflation, and whether the positive correlation between Bitcoin and stocks continues. Any shift in these factors will change the current market baseline of "pause de-escalation, risk repair."

Exclusive View from the MEXC Crypto Pulse Research Team

The truly important aspect of this conflict is not how much oil prices fluctuate in a single day, but how it clearly exposes Bitcoin's current asset characteristics. The market habitually calls Bitcoin "digital gold," expecting it to play a safe-haven role during geopolitical crises. But the market action on July 27 provided contrary evidence: Bitcoin did not rise when the conflict escalated; it rose when the conflict eased, oil prices fell, and inflation worries diminished. Its pricing logic has switched from "safe-haven asset" to "the most liquidity-sensitive risk asset."

The market may be misreading two things. First, it may misinterpret Bitcoin's rise as safe-haven demand. In reality, the driving force behind this Bitcoin rally was the easing of inflation due to falling oil prices and the repair of risk appetite. It moves with stocks and against oil, which is precisely the characteristic of a risk asset, not a safe haven. Second, it may misread the pause as an end to the conflict. This pause has effectively dismantled the previous ceasefire agreement, shipping through the Strait of Hormuz has not recovered, and the risk premium has not truly dissipated. The current risk-on repair is built on a fragile premise.

If we could only watch one thing, we suggest monitoring the actual shipping data through the Strait of Hormuz, rather than conflict news headlines. The pause in fighting is about sentiment, while the resumption of shipping is about supply. As long as strait transit volumes remain at one-tenth of pre-war levels, the risk premium on oil will not truly disappear, and uncertainty over inflation and policy will persist. Shipping data reflects the true extent of the shock more than any statement.

The implication for the crypto market is that Bitcoin is being increasingly embedded into the global macroeconomic transmission chain. When a Middle Eastern geopolitical variable can ultimately impact Bitcoin's price through the chain of "Strait > Oil Prices > Inflation > Fed," the independent narrative of crypto assets weakens further. This means Bitcoin will find it harder to chart an independent course in an inflation-driven tightening environment, and it also means investors must incorporate geopolitics and energy markets into their crypto asset analysis framework, just as they analyze stocks. The boundaries between asset classes are blurring, and true analytical depth lies precisely in understanding how these seemingly unrelated markets are tightly connected through these transmission chains.

Frequently Asked Questions

Why does the Iran conflict affect Bitcoin prices?

Through a transmission chain: The Iran conflict disrupts oil shipping through the Strait of Hormuz; shipping tightness drives up oil prices; higher oil prices exacerbate inflation; inflation affects the Fed's rate hike expectations; and rate hike expectations determine the liquidity environment for risk assets including Bitcoin. Therefore, when the conflict eases and oil prices fall, inflation concerns diminish, and risk assets like Bitcoin tend to benefit. In the current environment, Bitcoin operates on a risk asset logic, not a safe-haven one.

Why is the Strait of Hormuz so important?

Because it is the world's most critical oil chokepoint. According to TradingEconomics, the Strait of Hormuz carries about 20% of the world's crude oil and natural gas flows. Once shipping through the strait is disrupted due to conflict, global oil supply becomes severely strained, driving up prices. According to CNN, even with the conflict paused in July, fewer than 10 commercial vessels transited the strait over the weekend, compared to a normal pre-war level of about 100 per day. The supply-side tightness has not truly eased.

Are falling oil prices bullish for stocks and Bitcoin?

Typically, yes. Falling oil prices ease inflation concerns, reducing the pressure on central banks to raise rates, thereby improving the liquidity environment for risk assets like stocks and Bitcoin. On July 27, following the U.S.-Iran conflict pause, oil prices plummeted, stock markets rose, and Bitcoin returned above $65,000, reflecting this logic. However, it is important to note that if earlier oil price increases have already caused an inflation shock, this positive effect may be partially offset by the lagged effects of that inflation.

Is Bitcoin a safe-haven asset during geopolitical conflicts?

Currently, it behaves more like a risk asset than a safe haven. Although Bitcoin is often called "digital gold," the July 27 market action showed it rose when the conflict eased and oil prices fell, not in a risk-off move when conflict escalated. It moves with stocks and against oil, following risk asset logic. Safe-haven capital in this round of conflict flowed more towards gold than Bitcoin.

Does the pause in the U.S.-Iran conflict mean it's over?

Not necessarily. According to CNN, Trump stated the U.S. paused strikes at Iran's request but warned it would resume attacks if a new ceasefire agreement could not be reached. This pause has effectively dismantled the previous 60-day ceasefire agreement. It is a fragile pause, not an official ceasefire. Shipping through the Strait of Hormuz has not recovered, tanker insurance costs are high, and any action by either side could rapidly reverse the situation.
