Japan Cannot Rest Easy Despite OPEC+ Production Increase—Why Fuel Concerns Persist Even with More Oil

Seven countries from OPEC+—a coalition of the Organization of the Petroleum Exporting Countries and non-member oil-producing nations—have agreed to increase crude oil production by 188,000 barrels per day starting in August 2026. At first glance, this announcement seems to provide reassurance to the global oil market with the prospect of increased supply. Indeed, crude oil futures prices softened slightly following the production increase agreement, and the market has begun to focus more on "supply recovery" rather than "shortage."

However, from Japan's perspective, this news is not simply good news. The issue is not the decision by OPEC+ to increase production itself, but whether this oil will actually reach the market and how much it will impact Japan's fuel prices and overall cost of living.

The seven countries that decided on this production increase are Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria, and Oman. These are core members of OPEC+ and have previously engaged in voluntary production cuts. This decision can be seen as part of a gradual lifting of those voluntary cuts. OPEC has stated that it retains the flexibility to accelerate, halt, or retract the production increase depending on market conditions.

The term "flexibility" is key to understanding this news. While oil-producing countries are showing a willingness to increase supply, they also leave room to apply brakes if the market collapses. In other words, this is not a unilateral large-scale production increase but a cautious adjustment, gradually opening the taps while observing the market.

Why the caution? One reason is that concerns over the Strait of Hormuz have not been entirely dispelled. The Strait of Hormuz is a crucial maritime route for Middle Eastern oil to reach the global market. For Japan, it is a critical point for energy security. Even if oil production increases, if there are concerns about the transportation route, the actual amount reaching buyers will be limited. The market is focused not only on the ability to extract oil from the ground but also on the "transportability" that includes ports, tankers, insurance, navigation risks, pipelines, and alternative routes.

In this regard, reactions on social media and overseas investor forums are intriguing. In English-speaking oil-related communities, skeptical voices about the production increase are prominent, with comments like "How will they get it out of the Persian Gulf?" and "Isn't this just a paper increase?" Some even jokingly asked if the additional production would be transported by "dreams and hopes." Another user pointed out that if pipelines and alternative transportation methods are already near capacity, the export effect of the additional production would be limited.

These reactions are not just online cynicism; they touch on the essence of what market participants are observing. In the crude oil market, what matters is not the "production target" but the "actual amount reaching the market." Even if OPEC+ decides to increase production by 188,000 barrels, it only affects consumers and businesses once it is shipped from ports, transported by tankers, reaches refineries, and is refined into gasoline, diesel, naphtha, and other products.

For Japan, this issue is even more pressing. Japan relies heavily on overseas sources for most of its crude oil, with a particularly high dependency on the Middle East. According to data from the Agency for Natural Resources and Energy, over 90% of Japan's crude oil imports come from the Middle East. Compared to the United States and Europe, Japan's dependency on the Middle East is exceptionally high. This means that even a slight increase in tensions in the Strait of Hormuz could have a disproportionately large impact on Japan.

Of course, Japan has oil reserves. A system combining national reserves, private reserves, and joint reserves with oil-producing countries provides some resilience against short-term supply disruptions. Therefore, it's not as simple as saying that fuel will disappear from gas stations the moment something happens in the Strait of Hormuz.

However, reserves are not a panacea. They are a safety valve to buy time, not a permanent supply source. If oil transportation risks persist, procurement costs, insurance premiums, detour route expenses, and exchange rate impacts will accumulate, eventually affecting fuel prices, logistics costs, electricity rates, and chemical product prices. What Japanese consumers feel is not the crude oil market itself but the prices of gasoline, kerosene, delivery services, food, plastic products, and packaging materials.

The current OPEC+ production increase could serve as a factor to curb the upper limit of crude oil prices in the short term. If global supply concerns ease and speculative buying retreats, crude oil prices may become more likely to fall. For Japan, if the yen does not depreciate further, it could lead to reduced import costs. If the upward pressure on gasoline prices and electricity and logistics costs eases, it would be beneficial for both households and businesses.

However, it is important to note that "a drop in crude oil prices" and "a quick drop in consumer prices in Japan" are not the same. Domestic fuel prices in Japan are influenced not only by crude oil prices but also by exchange rates, refining costs, distribution costs, tax systems, subsidy policies, inventory valuation, and sales competition. Even if international crude oil prices fall slightly, the effect of reduced import prices may be diminished if the yen depreciates simultaneously. Conversely, even if crude oil prices remain stable, a stronger yen would lighten Japan's burden.

Moreover, a decline in crude oil prices is not always entirely beneficial for the Japanese economy. While lower energy costs are a tailwind for households and businesses, sudden price fluctuations can destabilize the earnings outlook for resource-related companies, trading houses, shipping, and plant-related sectors. Furthermore, if crude oil prices reflect "a slowdown in the global economy" or "weak demand from China," it could be a warning sign for Japanese export companies. It is necessary to discern whether the background of falling crude oil prices is due to increased supply or decreased demand.

This complexity is also reflected in the market reaction. While crude oil prices fell slightly following the production increase agreement, the market as a whole has not been significantly reassured. Traders are simultaneously watching the relationship between the United States and Iran, the navigation status of the Strait of Hormuz, China's crude oil imports, Russia's export trends, and supply increases from oil-producing countries outside the Middle East. It is not a situation where a single piece of news determines the market.

On social media, more voices are interpreting the production increase as a "signal amid lingering geopolitical risks" rather than a "measure against supply shortages." Among oil-related investors and traders, discussions include "I can't trust it until the barrels actually hit the market," "the transportation route is more of a problem than the production increase," and "there's a possibility of shifting from a shortage to an oversupply narrative." This indicates that the market's focus is shifting from "insufficient oil" to "oil that doesn't reach" and further to "oil with demand not returning."

The expected reactions on Japanese social media will likely be more relatable to everyday life. For example, "Will gasoline prices drop with the oil production increase?" "When will it reflect in electricity bills?" "Won't prices remain high once subsidies end?" Investors will look at the impact on energy stocks, trading company stocks, shipping stocks, and the yen exchange rate. Meanwhile, general consumers will look at the price displays at gas stations. Companies will look at diesel, heavy oil, naphtha, logistics contracts, and raw material prices. Even the same OPEC+ production increase holds different meanings depending on one's position.

In the field of Japanese companies, diversifying procurement sources has already become an important theme. If crude oil from the Middle East becomes unstable, it will be necessary to consider procurement from the United States, Asia, Central Asia, Africa, and other regions. However, crude oil is not a commodity that can be purchased the same way from anywhere. Refineries are designed and operated according to the characteristics of the crude oil they process. Differences in sulfur content, weight, and the proportion of products obtained after refining mean that changing procurement sources will affect refining efficiency and costs. Energy security is not as simple as "just buy from another country."

In this sense, the current OPEC+ production increase presents Japan with two messages.

The first is the expectation of short-term price stability. If supply increases, navigation through the Strait of Hormuz recovers, and global demand does not spike dramatically, the upward pressure on crude oil prices will be curbed. This is welcome news for Japanese households and businesses.

The second is the reaffirmation of medium- to long-term vulnerabilities. Japan cannot completely escape the geopolitical risks of the Middle East. Even with reserves, diplomatic relations, and long-term contracts with oil-producing countries, if transportation routes become unstable, Japan will be affected. Even when OPEC+ decides to increase production, the market does not immediately move towards comprehensive reassurance because many risks lie between where oil is "produced" and where it is "consumed."

Furthermore, from a decarbonization perspective, this news carries an ironic meaning. While the world is advancing renewable energy and electrification, the reality that oil prices shake lives and economies every time a crisis occurs becomes apparent. In Japan, discussions on electric vehicles, renewable energy, nuclear power, storage batteries, energy-saving technologies, hydrogen, and ammonia are ongoing, but dependence on oil remains significant. There are many sectors, such as logistics, aviation, shipping, chemical industries, agriculture, construction, and disaster prevention, where it is difficult to immediately replace oil.

In other words, the 188,000-barrel production increase by OPEC+ is both "news that gasoline might become cheaper" and "news that reminds Japan of its continued dependence on oil." While a temporary drop in crude oil prices might bring relief, structural challenges remain. Without simultaneously advancing diversification of procurement sources, operation of reserves, refinery flexibility, expansion of renewable energy, suppression of fuel demand, and logistics efficiency, the same concerns will recur repeatedly.

There are three points to watch going forward.

First, the actual production and export volumes after August. It is necessary to confirm how much the OPEC+ target increase will be reflected in the physical market.

Second, the navigation status of the Strait of Hormuz. The navigation of tankers, insurance premiums, port functions, and the operational status of alternative routes will influence the geopolitical risk premium of crude oil prices.

Third, the return of Asian demand, centered on China. If China, one of the world's largest crude oil importers, moves to buy back at low prices, the effect of the production increase could be absorbed, and the price decline might be limited.

What Japan must avoid most is being reassured by the headline of "production increase" alone. The current OPEC+ decision is indeed a positive factor on the supply side. However, the crude oil market has already become a complex market where not only simple supply and demand but also geopolitics, logistics, finance, exchange rates, decarbonization policies, and consumer countries' reserve strategies intertwine.

The production increase might be good news. However, what is truly important for Japan is not just whether oil becomes cheaper. It is about how much the structure that shakes living costs and corporate activities during each crisis can be changed. Now that OPEC+ has slightly opened the taps, Japan is entering a phase where it should consider an "energy system that won't panic in the next crisis."
