AI Summary
5 min readThe Strait of Hormuz has been closed for over a month—an event with no historical precedent. Rajiv Sibyl, Senior Global Economist at Morgan Stanley, argues that the real economic risk from an oil shock is not the price of oil itself, but what happens next. The shock ripples through inflation, growth, central bank policy, and markets in a sequence that matters greatly. The episode examines how different regions are reacting to a supply disruption that could last many quarters, not just months.
The Mechanism: Sequence Over Price
The central framework is that an oil supply shock creates a tricky mix of rising inflation and slowing growth, and the order in which these effects hit determines the policy response. Sibyl explains that the price of oil is only the starting point. If the Strait of Hormuz reopens rapidly, oil prices would likely decline quickly, but the economic problems from the shock would not disappear as fast. Conversely, if oil moves past $125 per barrel—the level at which demand begins to destruct, meaning people must reduce consumption because of price—the global economic impact becomes much more dramatic. The current in-between scenario, with oil hovering between $100 and $125 for weeks, creates confusion and modeling problems for central banks.

What you'll learn
- 1 (00:00) **Introduction: The Real Risk Isn't the Oil Price** - Rajiv Sibyl frames the episode's core thesis: the economic danger from an oil shock is not the price spike itself, but the subsequent ripple effects through inflation, growth, and central bank policy.
- 2 (00:48) **Three Oil Price Scenarios** - Morgan Stanley's global team modeled a range of outcomes based on the Strait of Hormuz closure.
- 3 (01:47) **Regional Impact: Asia's Mixed Exposure** - Asia is the most physically exposed to Middle East oil, but has buffers that delay the shock.
- 4 (02:49) **Regional Impact: Euro Area's Fast Inflation Pass-Through** - In contrast to Asia, inflation passes through quickly in the Euro area, affecting both headline and core.
- 5 (03:15) **Regional Impact: The Fed's Different Calculus** - The U.S. is primarily a services-based economy, so oil supply shocks affect headline inflation and consumption, not core inflation.
- 6 (03:48) **Key Takeaway: Inflation Leads, Growth Follows, but Reactions Differ** - Every economy has a different pass-through mechanism, forcing central banks and fiscal policy to react differently.

Rajeev Sibal: Welcome to Thoughts on the Market. I'm Rajeev Sibal, Senior Global Economist at Morgan Stanley.
Today, economic risk from an oil shock isn't the price of oil itself – but really what happens next?
It's Tuesday, April 7th at 3pm in Dubai.
An oil shock doesn't stop at the gas pump. It ripples through inflation, growth, central bank policy, and ultimately markets. As you've heard from my colleagues over the past several weeks, this time may be different. We're not just dealing with a temporary price spike. The closure of the Strait of Hormuz is historically unprecedented. We're well over a month now, and we're looking at the implication of a supply shock that could last many quarters. This could evolve into something far more complex.
This is a tricky mix of rising inflation and slowing growth, and the sequence matters greatly. At Morgan Stanley, a collaboration between the economists and the strategists globally looked at a wide range of scenarios of where oil prices may go.
If the Strait of Hormuz were to reopen rapidly, we would see oil prices probably decline rather quickly. That doesn't mean that the problems from the oil shock are going to go away very quickly. But it does mean that the price of oil may move down more quickly. Conversely, if we see a complete closure and an escalation in the conflict, the oil price is probably going to go much, much higher. And in a world where oil moves past $125, which is usually the level at which demand starts to destruct in the economy, i.e. people have to reduce their consumption of oil because of the price, we would see a much more dramatic impact in the global economy.
Right now, we're in the in-between scenario. We see oil hovering between $100 and $125 for a number of weeks now, and this creates a lot of questions and confusions and modeling problems for many central banks. I want to go through some of the key regions of the world to talk about how they are reacting to what is happening right now.
Asia is a little bit unusual. Asia is the most exposed to what's happening in the Middle East. Most oil and gas that leaves the Middle East goes to Asia in terms of physical volumes. The challenge is that many Asian economies have huge buffers in place or reserves. They also use fiscal policy to help subsidize and smooth the price of oil so that the consumer does not experience the shocks as dramatically as they would otherwise.
As a result, there is a mix of countries in Asia that are grapplin
