Welcome to Thoughts on the Market. I’m Mayank Maheshwari, Morgan Stanley’s research analyst covering energy markets in India and Southeast Asia.

Today—how disruptions linked to Iran and the Strait of Hormuz are creating energy-related disruptions across Asia.

It’s Monday, March 23rd, at 8am in Singapore.

To understand the scale of the impact, let’s start with a simple fact: about a quarter of Asia’s energy—that is oil, liquefied natural gas, and propane—comes from the Middle East, much of it flowing through a single chokepoint, the Strait of Hormuz. Any disruption here affects more than just oil prices. It also hits power generation, industrial output and even food supply chains across the region.

Asia hasn’t seen a true energy access shock in over 50 years. So that makes this moment very critical. And with oil around $100 per barrel, stress is building in the system. Diesel margins are double pre-conflict levels. Jet fuel premiums have nearly doubled. And Dubai crude—normally cheaper than Brent historically—is now trading at a premium of more than $20 per barrel. This kind of price move signals tightening supply chains.

Asia’s dependence on [the] Middle East runs deep. Refiners source up to 80 percent of crude from the region, and 30–40 percent of LNG imports originate there. For major economies like India and China, roughly 40–50 percent of oil demand passes through Hormuz. It’s a critical energy highway. And when flows slow, the entire system backs up.

Inventories may look like a buffer. Asia holds around 65–70 days of crude. But the system reacts sooner than waiting to run out. Governments are already rationing energy, industries are cutting LNG and LPG usage, and export restrictions are limiting downstream production of fuels. The tightening has already begun.

The real pressure point may not be oil, but natural gas—particularly LNG, as Qatar, which is a big supplier of Asia's LNG, has seen infrastructure damage. Asia accounts for about half of global LNG consumption, with up to 40 percent secured from the Middle East. Unlike oil, LNG has very limited buffers; in number of days, and not in months.

This is where the story extends well beyond energy. Around 25 million tons per year of petrochemical capacity has been impacted, along with roughly 10 million tons of fertilizer production. Prices for key materials like polymers have risen 15–25 percent in just a few weeks, and the premiums are still rising. These inputs feed into everyday products—from cars and electronics to packaging and agriculture. Even basic services are affected, with cooking gas shortages hitting restaurants in parts of Asia.

Policymakers are responding, but options are limited. Around 100 million barrels of crude has been released from reserves. Countries are securing higher-cost LNG cargoes. And many are turning back to coal for reliability despite environmental trade-offs.

Ultimately, the longer this disruption persists, the more pressure builds across energy, power, chemicals, and food systems. And in a region as interconnected and import-dependent as Asia, those ripple effects spread quickly—and widely.
