When a geopolitical shock hits energy markets, a recurring pattern emerges: diesel prices surge rapidly, while gasoline lags behind.

According to data from the U.S. Energy Information Administration (EIA), from the beginning of the conflict in Iran until April 6, 2026, the average price of gasoline in the United States increased by $1.11 per gallon, while diesel prices jumped by $1.75 per gallon.

This disparity is particularly significant because diesel forms the backbone of the transportation and logistics sectors, intensifying inflationary pressures across the economy.

This same pattern was observed following Russia’s invasion of Ukraine and is now repeating as oil tanker movements through the Strait of Hormuz are disrupted due to Middle East tensions.

This raises a fundamental question: Why does diesel react so much faster than gasoline?

The answer is structural rather than situational, as diesel occupies a pivotal position in the global economy in a way that gasoline does not.

Diesel starts with a lower supply safety margin

One of the less-noticed factors is that diesel typically operates with narrower safety margins. Distillate fuel inventories—which include diesel and heating oil—are often lower than gasoline stocks. In both 2022 and during recent disruptions, these inventories were already below typical seasonal levels before the geopolitical shock occurred, leaving limited room to absorb any sudden supply shortfall.

In contrast, gasoline benefits from larger storage capacities, broader domestic production, and more defined seasonal demand patterns. Diesel lacks these advantages, so it feels any shortage first and most acutely.

Diesel is a global fuel… gasoline is regional

Gasoline is primarily a regional product, often refined and consumed within the same geographic market.

Diesel, however, is the fuel of global trade, powering the ships, trucks, trains, and heavy equipment that move goods across borders.

Therefore, its prices are closely tied to global trade flows. When a vital corridor like the Strait of Hormuz is disrupted, the repercussions ripple through diesel markets worldwide, even in countries that do not rely heavily on Middle Eastern oil, due to its global trade nature.

Demand for diesel is broader and less elastic

Another fundamental difference lies in the nature of demand.

Gasoline demand is mainly linked to passenger vehicles, and consumers can scale back consumption when prices rise.

Diesel, however, fuels sectors that are difficult to forgo, such as:

* Long-haul trucking

* Railways

* Maritime shipping

* Construction and mining

* Agriculture

* Industrial activity

These sectors do not have easy alternatives; goods transport, agricultural operations, or construction projects cannot be halted because of price hikes. Additionally, the spring planting season is one of the most diesel-intensive periods, adding pressure on demand at a sensitive time.

Refineries cannot simply increase diesel production

In theory, higher prices should lead to increased production, but the reality is different. Diesel and gasoline production rely on different parts of an oil barrel, and switching between them is not easy.

Furthermore, diesel production requires complex technical conditions, such as crude quality, processing capabilities, and ultra-low sulfur requirements. Refineries often operate near maximum capacity, especially during high-demand periods, with routine maintenance further reducing flexibility.

In the United States, for example, refineries are currently focused on increasing gasoline production in preparation for the summer driving season, limiting their ability to boost diesel output quickly.

Cumulative seasonal and structural pressures

Diesel also faces seasonal competition for supplies, particularly in winter when demand for heating oil increases. Even outside this season, demand cycles from agriculture, construction, and transportation overlap, maintaining high consumption levels throughout the year.

Diesel is the transmission channel for inflation

Perhaps the most important difference is diesel’s impact on the economy. It is the fuel used to transport goods; thus, rising prices increase transportation costs, which in turn pass through to the prices of food, construction materials, and consumer goods.

In the United States, trucks move about 70% of goods. When diesel prices rise, this increase spreads through supply chains and is often passed on to consumers.

In contrast, gasoline directly affects individuals, but its systemic impact is far less than that of diesel.

The pattern repeats for an obvious reason

What we are seeing today is not an exception, but a repetition. After Russia’s invasion of Ukraine, diesel prices rose much faster than gasoline due to global supply tightness. Today, Middle East disruptions are reproducing the same scenario.

Diesel prices rise faster than gasoline during global crises because the market is tighter in terms of supply, more globally interconnected, and less elastic in its response.

Diesel is not just a fuel… it is the engine of the global economy. When this economy comes under pressure, diesel is the first to move—and with the strongest momentum.

U.S. stocks surged on Friday after Iran announced the "full" reopening of the Strait of Hormuz to commercial navigation, following the ceasefire declaration between Israel and Lebanon.

The Dow Jones Industrial Average jumped by approximately 1005 points, or 2.1%, while the S&P 500 rose 1.3%, surpassing the 7100 level for the first time in history. The Nasdaq also climbed 1.5%, with both indices reaching new record highs during trading. Similarly, the Russell 2000 index hit an all-time high, rising by about 2%.

In a post on the "X" platform, Iranian Foreign Minister Abbas Araghchi announced that "in line with the ceasefire in Lebanon, the passage of all commercial vessels through the Strait of Hormuz has been declared fully open during the truce period, according to the coordinated route previously announced by the Ports and Maritime Organization of the Islamic Republic of Iran."

U.S. President Donald Trump had stated on Thursday that the leaders of Israel and Lebanon agreed to a 10-day truce, which went into effect at 5:00 PM ET.

Following Iran's announcement, oil prices dropped sharply as concerns over supply disruptions receded. U.S. West Texas Intermediate (WTI) crude contracts plunged by about 14% to trade above $80 per barrel, while global benchmark Brent crude contracts fell 13% to trade above $86 per barrel.

In a separate post on "Truth Social," Trump thanked Iran for reopening the Strait, but simultaneously emphasized that the U.S. Navy's naval blockade on Iranian ports "will remain fully in place" until a peace agreement is reached with Tehran, adding: "This process should move very quickly, as most points have already been negotiated."

Hopes for a peace agreement have pushed markets to record levels in recent days, with the three major indices heading toward strong weekly gains; the Dow Jones has risen by about 3%, the S&P 500 by more than 4%, and the Nasdaq has jumped by more than 6%.

Iran announced on Friday the full reopening of the Strait of Hormuz to commercial ship traffic during the ceasefire period between Israel and Lebanon, a move that could ease the intensity of global energy market disruptions.

In a social media post, Iranian Foreign Minister Abbas Araghchi stated: "In line with the ceasefire in Lebanon, the passage of all commercial vessels through the Strait of Hormuz has been declared fully open for the remainder of the truce." He added that ships are required to transit via a "coordinated route" announced by Iranian maritime authorities.

Israel and Lebanon had agreed on Thursday to a 10-day truce that began at 5:00 PM ET. The Israeli military campaign in Lebanon against Hezbollah, a close ally of Iran, had constituted one of the most prominent obstacles in the negotiations between Washington and Tehran.

For his part, U.S. President Donald Trump thanked Iran for reopening the Strait in a social media post, but emphasized simultaneously that the naval blockade imposed by the United States on Iranian ports will remain in place until a deal is reached with Tehran.

Oil prices plummeted by more than 10% to below $90 per barrel as concerns over supply disruptions receded. Approximately one-fifth of global crude oil supplies passed through the Strait before the outbreak of the war; the closure of this maritime corridor, which links the Arabian Gulf to global energy markets, had led to the largest disruption of oil supplies in history.

On April 7, Trump had agreed to a two-week truce in exchange for Iran’s full opening of the Strait. However, the Speaker of the Iranian Parliament, Mohammad Bagher Ghalibaf, accused the United States of violating the agreement by allowing Israel to continue its military operations in Lebanon.

During the ceasefire period between the United States and Iran, the Strait remained almost entirely closed amid disagreements between the two sides over the terms of the agreement, with only a limited number of commercial vessels crossing daily.

In a related context, negotiations held last weekend in Pakistan between U.S. Vice President JD Vance and Ghalibaf did not yield a permanent agreement to end the war between Washington and Tehran. Trump stated that negotiators from both sides might meet again over the weekend in Pakistan for a second round of talks.

Bitcoin stabilized on Friday slightly below the $75,000 level, heading toward its third consecutive weekly gain, supported by a rally in high-risk assets amid hopes for the resumption of talks between the United States and Iran over the weekend.

The world’s largest digital currency, Bitcoin, fell by 0.3% to $74,790.8 by 02:23 AM ET (06:23 GMT), but remains on track for weekly gains of approximately 5%.

Despite this positive performance, Bitcoin struggled to decisively break through the psychological $75,000 level, after briefly exceeding it earlier in the week.

Support from Hopes of Geopolitical De-escalation

Market sentiment improved, supported by receding geopolitical risks, following the entry into force of a U.S.-mediated 10-day ceasefire between Israel and Lebanon, aimed at halting hostilities and opening the way for further negotiations.

This temporary truce, which can be extended by mutual agreement, helped calm fears of an expanding conflict in the region, which had negatively impacted markets earlier.

U.S. President Donald Trump also signaled the possibility of resuming talks between Washington and Tehran as early as this weekend, bolstering hopes for broader de-escalation in the Middle East.

However, Bitcoin's gains remained limited as some investors moved to take profits after recent rallies, alongside strong resistance near the $75,000 level, which has so far capped further upside.

Global Markets Support High-Risk Assets

Digital currencies benefited from positive momentum in global markets, where U.S. stocks, particularly technology shares, hit new record highs this week, supporting assets that typically move in tandem with risk appetite.

Cyberattack Hits "Grinex" Platform

In a separate context, the Russia-linked cryptocurrency exchange Grinex announced the suspension of its operations after suffering a cyberattack that led to the theft of approximately one billion rubles (about $13 million), according to a statement published via Telegram.

The platform, which is based in Kyrgyzstan and is subject to sanctions from the United States, the United Kingdom, and the European Union, explained that the attack used "highly sophisticated" methods, pointing to the possible involvement of "foreign intelligence services" and asserting that the goal was to undermine the Russian financial system.

Mixed Movements for Altcoins

Alternative digital currencies saw a mixed performance in volatile trading:

- Ethereum, the second-largest digital currency, fell 1.3% to $2,324.92.

- In contrast, Ripple rose by 1.4% to $1.43.

Overall, the cryptocurrency market remains within a cautious range, as investors await any new developments regarding geopolitical tensions, which have become a primary factor in directing global risk appetite.
