The oil market entered Tuesday caught between two completely different stories.

On one side is a supply shock that has pushed crude around the $100-a-barrel level, disrupted shipping through the Strait of Hormuz and introduced fresh risks across the Middle East.

On the other is the possibility of diplomacy.

Oil prices initially rose on September 22 as traders awaited potential U.S.-Iran talks at the United Nations General Assembly and assessed the latest developments in regional crude shipments. Brent’s November contract was up about $1.14, or 1.1%, to $101.48 a barrel, while U.S. West Texas Intermediate’s October contract gained about 0.9% to $96.65.

But the market then shifted sharply.

Reports that Iran could be prepared to reopen the Strait of Hormuz within a week, provided the United States eased military pressure and lifted a blockade on Iranian ports, sent oil prices lower. Reuters later reported Brent at around $99.45 and WTI October near $94.69, illustrating just how quickly geopolitical headlines are moving the market.

The result is a market where every diplomatic signal can move prices by dollars in a matter of hours.

The Strait of Hormuz is one of the world's most important energy chokepoints.

Roughly one-fifth of global oil and liquefied-natural-gas trade normally passes through the waterway, making disruptions there unusually significant for crude, gasoline, diesel and LNG markets.

The current disruption has been severe.

Reuters reported that vessel traffic through the strait fell to just two ships on Monday, compared with around 125 large commercial vessels that typically passed through the waterway each day before the February 28 conflict. The latest figures do not capture vessels that may have switched off automatic identification systems, but the decline still illustrates the scale of the disruption.

Two vessels were also reported attacked in the strait. An Isle of Man-flagged crude tanker was struck by a projectile and two crew members were injured, while an LPG carrier was damaged by debris. Both vessels remained operational.

For the oil market, that means the supply problem is not simply about production.

It is also about transportation.

Saudi Arabia has been one of the most important pieces of the supply puzzle.

A September 13 drone attack on the kingdom's East-West Pipeline disrupted crude shipments through the Red Sea port of Yanbu. Saudi Aramco subsequently increased exports through Gulf terminals instead.

Satellite tracking data showed Aramco loaded roughly 14 million barrels of crude onto seven VLCC supertankers at Ras Tanura on September 20.

That helped increase Saudi crude flows through Hormuz to about 2.9 million barrels a day, compared with approximately 700,000 barrels a day in August.

The shift is strategically important.

The Gulf route is more exposed to the Hormuz bottleneck, but using available tanker capacity allows Saudi Arabia to keep exports moving while the alternative pipeline route is repaired.

Saudi Arabia has also been using ship-to-ship transfers near Oman.

Reuters reported that roughly 60 million barrels had been moved from Ras Tanura for ship-to-ship loading around the Omani port of Sohar, demonstrating how logistics companies are adapting to the disruption.

This explains why crude prices initially eased from earlier highs.

More Saudi barrels are moving.

Hormuz shipments have recovered from extremely depressed levels.

And diplomatic discussions offer the possibility that the broader disruption could eventually unwind.

But none of those developments eliminates the underlying risk.

The market remains exposed to further attacks, renewed shipping disruptions and political escalation.

That is why crude can fall in response to hopes of diplomacy one hour and rise again when the next security headline hits.

The oil market is effectively pricing both outcomes simultaneously.

Washington and Tehran have exchanged threats while also leaving the door open to negotiations.

U.S. President Donald Trump said he was open to meeting Iranian President Masoud Pezeshkian, who is expected to be in New York for the U.N. General Assembly. Iran has also communicated conditions through mediators for re-engaging in negotiations.

Iranian officials have said the country could reopen Hormuz within a week if Washington eases military pressure and lifts its blockade.

That is one of the most important oil-market developments of the day — but it remains conditional.

There is no guarantee that negotiations will succeed.

And even if an agreement is reached, reopening a waterway is not the same as immediately restoring normal commercial traffic.

Shipowners must assess security.

Insurance companies must adjust risk calculations.

Oil companies need to restore infrastructure.

And traders need confidence that shipments will remain protected for more than a few days.

The Middle East is not the only source of disruption.

In Libya, an armed group closed a valve on the pipeline carrying crude from the Sharara oilfield to the Zawiya port.

The National Oil Corporation said the shutdown significantly reduced production at one of the country's largest fields. Engineers cited by Reuters estimated output had fallen by around 200,000 barrels per day, leaving production between approximately 100,000 and 105,000 barrels per day.

That is a relatively small amount compared with global demand, but it matters because the oil market is already operating with unusually high geopolitical risk.

When several disruptions happen simultaneously, traders begin to focus on cumulative losses rather than individual incidents.

A pipeline outage in Libya becomes more important when shipping is disrupted in the Gulf.

A Saudi export rerouting becomes more important when another production center loses output.

And the combined uncertainty can keep crude volatility elevated even when headline prices are falling.

The latest development could provide another source of relief.

Reuters reported Tuesday that Saudi Arabia had restarted the East-West Pipeline at a reduced flow rate and could resume crude exports from Yanbu later in the day, according to sources familiar with the situation. The pipeline had been shut following the September 13 drone attacks.

That would gradually restore one of Saudi Arabia's most important alternatives to the Gulf export route.

For the oil market, additional pipeline capacity is potentially just as important as additional crude production because it reduces pressure on the maritime system.

Fewer barrels need to pass through the most vulnerable chokepoint.

Crude hovering around $100 is psychologically and economically important.

At that level, higher fuel costs can feed into transportation, manufacturing, aviation and household energy expenses.

For oil-producing countries, however, high prices can increase export revenues.

For central banks, persistent energy inflation complicates the task of managing broader price pressures.

That means oil is not just another commodity in the current environment.

It has implications for inflation, monetary policy, currencies and financial markets.

The extraordinary volatility of the past several sessions illustrates why traders are closely following diplomatic headlines instead of relying solely on traditional supply-and-demand forecasts.

On one day, Brent can gain more than 3% on geopolitical fear.

The next day, it can fall more than 3% on the prospect of diplomacy and increased exports.

Even if Saudi Arabia restores the East-West Pipeline and Iran eventually reopens Hormuz, shipping companies still face a complicated environment.

Reuters reported that vessel traffic remained dramatically below normal levels and that ships had already faced attacks or hazardous incidents in the strait.

As a result, the reopening of a maritime route would probably need to be accompanied by confidence that tankers can safely use it.

That is especially important because oil transportation costs have already risen sharply.

Tanker availability, insurance rates, routing decisions and loading schedules can all affect the delivered price of crude.

The market may therefore experience a lag between a diplomatic breakthrough and a full normalization of physical oil flows.

That tension explains the unusual price behavior.

At first, oil climbed as traders anticipated possible U.S.-Iran talks.

Then reports suggesting Iran could reopen Hormuz triggered a sharp reversal.

At the same time, Saudi exports have increased, its damaged pipeline is being restored, and Libya has suffered a new production setback.

In other words, the supply picture is improving in some areas and deteriorating in others.

That leaves crude extremely sensitive to headlines.

The next major catalyst is likely to be concrete evidence about whether Washington and Tehran can move from statements to negotiations and whether any agreement can restore safe, sustained shipping through Hormuz.

Until then, $100 oil remains less a fixed price target than a battlefield between two competing forces: the physical reality of disrupted energy infrastructure and the possibility that diplomacy could rapidly bring more barrels back to global markets.

For traders, consumers and energy companies, that means one thing above all: the oil market is still being driven by events that can change much faster than traditional supply-and-demand models can.
