The Strait of Hormuz is showing signs of reopening.
But for the chemical industry, that does not mean supply chains will immediately return to normal.
ICIS reported on June 18 that even if the temporary U.S.-Iran agreement takes effect, freight forwarders still expect traffic through the Strait of Hormuz to take months to recover.
That point matters.
The question is no longer only whether the strait can reopen.
It is whether shipowners are willing to sail, insurers are willing to cover risks, ports can operate smoothly, and cargoes can arrive on time.
For the chemical market, reopening is only the first step.
The harder part is restoring the logistics rhythm that has already been disrupted.
This Is Not an Ordinary Shipping Lane
The importance of the Strait of Hormuz does not need much explanation.
The waterway carries up to 30% of global seaborne oil and 20% of global LNG.
For Asia’s chemical market, its weight is even heavier.
In 2025, the Strait of Hormuz accounted for 45% of Asia’s LPG imports and 64% of Asia’s naphtha imports.
These two figures are enough to show the scale of the risk.
LPG and naphtha are key feedstocks for Asia’s petrochemical chain.
LPG is closely linked to PDH, propylene and polypropylene.
Naphtha is connected to steam cracking, ethylene, aromatics, polyolefins, MEG, PTA and multiple downstream chains.
So Hormuz is not only an oil price story.
It affects the entire chain from energy and chemical feedstocks to plastics, fibers, packaging, coatings and construction materials.
Middle Eastern PE Exports Depend on This Route
The Middle East is also a major source of global PE exports.
In 2025, the Middle East accounted for 41% of global PE exports.
More importantly, around 84% of Middle Eastern plastics and chemicals exports moved through the Strait of Hormuz.
That means any uncertainty around Hormuz affects more than oil tankers.
Chemical carriers, LPG vessels, naphtha cargoes and polyolefin shipments can all be affected.
Even if the route is now showing signs of reopening, the market should not assume that Middle Eastern supply will immediately become stable again.
The reason is simple: a strait can be reopened by agreement, but commercial confidence cannot be rebuilt overnight.
Shipowners need to assess risk.
Insurers need to reprice coverage.
Freight forwarders need to confirm routes.
Buyers need to rearrange arrivals.
Ports need to deal with previous disruptions.
All of this takes time.
Oil Prices Move First, Chemical Logistics Move Later
One common market mistake is to treat oil price movement as proof that chemical supply has recovered.
After geopolitical risk eases, crude prices may fall first.
But chemical logistics usually recover more slowly.
Chemical shipments are more complicated than ordinary bulk cargoes.
Many products involve hazardous classification, dedicated vessel requirements, special packaging, port qualifications, customs documents and storage conditions.
For LPG, naphtha, methanol, sulfur, PE and PP, lower prices do not mean cargoes can immediately arrive.
Cost-side risk premiums can retreat first, while execution risks in the supply chain may remain.
That is why freight forwarders expect traffic recovery to take months.
The market does not return to normal simply because vessels start moving again.
Ships must be willing to sail.
Cargoes must be scheduled.
Insurance must be acceptable.
Buyers must receive material on time.
Asian Buyers Are the Most Exposed
A slow Hormuz recovery will affect Asian buyers most directly.
China, India, Japan and South Korea are all major buyers of Middle Eastern energy and chemical feedstocks.
These markets import not only crude oil and LNG, but also large volumes of LPG, naphtha, methanol, sulfur, polyolefins and other chemicals.
If Middle Eastern cargo flows recover more slowly than expected, Asian buyers may face several problems.
Arrival schedules may remain unstable.
Spot offers may fluctuate.
Term contract execution may be delayed.
Alternative supply may not be cheap.
Inventory strategies may become more cautious.
This means the Asian chemical market may enter an awkward stage in the short term: prices may look cooler, but buyers may still be unable to relax.
Buyers will not only look at price.
They will also look at vessel schedules, inventories, letters of credit, insurance costs and actual arrival timing.
Supply Chains Recover More Slowly Than Headlines
The reopening of Hormuz is good news.
But for the chemical industry, it is not the end of the issue.
Over the past months, geopolitical tensions have already changed procurement timing and inventory behavior.
Some buyers stocked up earlier.
Some buyers reduced exposure.
Some sellers raised offers.
Some shipowners adjusted routes.
Some companies began looking for alternative sources.
These changes will not disappear immediately because of one agreement.
Supply chains always recover more slowly than headlines.
That is the main risk the market should watch now.
If the market prices in a full logistics recovery too early, it may underestimate real arrival pressure.
If buyers reduce inventory too quickly, they may become exposed again if vessel delays continue.
For traders, the key task now is not to read sentiment.
It is to confirm execution.
Where is the cargo?
When will the vessel sail?
How much is insurance?
Is the port congested?
Can the buyer receive the material on time?
These questions matter more than simply judging whether prices will rise or fall.
Hormuz May Be Open, But the Market Is Not Fully Relaxed
The reopening signal from Hormuz has reduced the market’s most extreme fears.
But the chemical industry should not focus only on the word “reopening.”
This waterway connects not only oil trade, but also Asia’s chemical feedstock supply and Middle Eastern plastics exports.
When one route carries such a large share of global energy and chemical logistics, recovery is not a simple question of open or closed.
It is a slow repair process.
In the short term, crude oil and some chemical prices may continue to give back risk premiums.
But from a logistics perspective, actual arrivals of LPG, naphtha, PE, PP, methanol and sulfur still need to be closely watched.
The most dangerous moment for Hormuz may have passed, but the chemical supply chain has not fully returned to normal.
