Oil Prices Skyrocket After US-Iran Dispute, Threatening Malacca Strait

Oil prices surged on Wednesday after US President Donald Trump declared that the ceasefire agreement with Iran had ended and vowed to attack Iran again, effectively ending the fragile peace agreement just one month after it was signed. Iran had attacked three commercial vessels in the Strait of Hormuz on Tuesday, which were using an alternative route near the coast of Oman rather than the northern corridor controlled by Tehran, leading to retaliatory strikes by the United States.

Iran has threatened to completely close the Strait of Hormuz again and double the number of targets attacked across the region as the US after US military forces attacked more than 80 targets inside Iran, including air defense networks, radar arrays, and over 60 IRGC fast boats. Now, energy investors are shifting their attention to another critical maritime chokepoint - the Malacca Strait.

The Hormuz Crisis and Global Consequences

A recent CNBC report noted that energy markets are increasingly concerned that the precedent set in Hormuz could spread to Southeast Asia with copycat measures. Iran and Oman have recently proposed jointly managing Hormuz by imposing new fees on commercial vessels passing through. Tehran considers these payments mandatory for all commercial vessels transiting the Strait of Hormuz. However, Oman describes them as optional service fees including maritime assistance, search and rescue operations, and environmental protection.

Omani officials maintain that these fees are not transit fees and compare the system to the voluntary service arrangements used in the Malacca Strait. However, investors fear that if transit fees are normalized in the Middle East, countries surrounding the Malacca Strait might see an opportunity to follow suit.

The Malacca Strait: A Strategic Energy Nexus

The Malacca Strait is a 900-kilometer waterway bordering Indonesia, Malaysia, and Thailand between the Malay Peninsula and Indonesia's Sumatra island. Located at the southern entrance of the strait, the city-state of Singapore serves as the world's busiest container transshipment hub and the largest bunkering location. Over 94,000 vessels pass through the strait annually, transporting essential energy and agricultural commodities. It is the shortest shipping route connecting the Indian and Pacific Oceans, serving as a vital artery for up to 30% of globally traded goods and nearly half of all seaborne oil transportation.

More specifically, it is the shortest sea route connecting Middle Eastern crude oil to East Asia, serving major economies such as China, Japan, and South Korea. The strait narrows to a tight bottleneck at its narrowest point - the Phillips Channel near Singapore - where it is only 2.8 kilometers wide, making it one of the world's most critical maritime chokepoints. If the passage were blocked, oil tankers would have to detour around the Australian continent, adding 10 to 15 days to transit time and significantly increasing fuel costs.

The "Malacca Problem" and Alternative Routes

China particularly faces a significant risk widely known as the "Malacca Problem" because up to 80% of its imported oil depends on passing through the Malacca Strait. Fortunately, the Malacca Problem has prompted Beijing to develop alternative overland and pipeline routes under the Belt and Road Initiative through Myanmar and Pakistan to avoid this bottleneck. These routes include the China-Myanmar Economic Corridor (CMEC) as well as the China-Pakistan Economic Corridor (CPEC).

The CMEC is a massive infrastructure and development network in an inverted Y shape under China's Belt and Road Initiative. Stretching from China's inland Yunnan province to the Myanmar coast, this journey provides Beijing with strategic direct access to the Indian Ocean and the Bay of Bengal. The journey starts at Kunming, enters Myanmar at border towns like Muse, runs to the central city of Mandalay and then splits into two branches ending at the commercial hub of Yangon and the strategic deep-sea port of Kyaukpyu in Rakhine state.

China-Myanmar Oil and Gas Pipeline Project

The flagship projects of CMEC include the China-Myanmar Oil and Gas Pipeline often involving China National Petroleum Corporation (CNPC), a vital energy link bypassing the Malacca Strait. Running from Kyaukpyu on the Myanmar coast to Yunnan, it transports up to 22 million tons of crude oil annually, generating about 22 million USD in direct revenue and 13.6 million USD in transit fees for Myanmar. Despite ongoing civil conflict in Myanmar, China has increased security to protect these strategic energy routes, operating alongside planned deep-sea port and special economic zone projects in Kyaukpyu.

Regional Responses and Global Impact

Japan, South Korea, and other major importers in Asia have also spent years diversifying crude oil suppliers, expanding strategic oil reserves, and investing in LNG and pipeline infrastructure to mitigate maritime disruption risks. However, despite these efforts, the Malacca Strait remains the primary gateway for most of Asia's imported energy, meaning any attempts to normalize transit fees or other restrictions there would ripple across the global energy market.

Energy Market Consequences

Potential conflict in Malacca would have profound implications for the global energy market. Imposition of transit fees or other restrictions at the strait would increase operating costs for oil tankers, squeeze profit margins for global oil traders and refiners. Increased uncertainty and costs would accelerate market volatility, push up marine insurance premiums, and create upward price pressure on global oil.

For economies heavily dependent on imported oil passing through Malacca such as China, Japan, and South Korea, the consequences would be particularly severe. China, with 80% of its imported oil dependent on the strait, has heavily invested in alternative routes like CMEC and CPEC. However, these routes still cannot fully replace Malacca's role in the near future.

Other countries in the region are also seeking to mitigate risks. Japan and South Korea have strengthened strategic oil reserves and diversified crude oil sources. Singapore, with its strategic location at the southern entrance of the strait, is heavily investing in energy infrastructure to maintain its central role in the global energy supply chain.

Conclusion

The escalating tensions between the US and Iran are creating ripples across the global energy market. The surge in oil prices not only reflects the current situation in the Strait of Hormuz but also concerns about tensions potentially spreading to other strategic sea routes like Malacca. Countries dependent on maritime routes for their energy supplies are facing growing challenges in ensuring energy security.

In this context, developing alternative routes and diversifying energy sources has become more urgent than ever. Initiatives like China's Belt and Road Initiative, along with efforts by other countries in the region, will play a crucial role in mitigating risks associated with potential maritime chokepoints.

However, in the short term, the energy market may continue to experience significant volatility as geopolitical tensions escalate. Investors and policymakers need to closely monitor developments in both Hormuz and Malacca, as these events could have far-reaching implications for global energy security and world economic growth.
