Crude is heading lower for a fourth straight day as traders increasingly believe diplomacy could reopen the Strait of Hormuz and restore disrupted global energy flows.

Oil prices are losing their geopolitical premium.

Crude fell more than $1 on Thursday, extending a multi-session decline as markets reacted to growing hopes that negotiations involving Iran could eventually improve shipping conditions through the Strait of Hormuz.

At 0645 GMT, Brent crude was down about $1.07, or 1.2%, at $86.77 a barrel, putting the benchmark on track for a fourth consecutive daily decline. West Texas Intermediate was down roughly $1.13, or 1.4%, at $81.10, extending its losing streak to five sessions.

The decline is important because oil prices had spent weeks incorporating a significant geopolitical premium.

The Strait of Hormuz is one of the world's most important energy chokepoints. Before the conflict began, the waterway handled oil and natural-gas shipments equivalent to roughly one-fifth of global consumption of those fuels.

Any prolonged disruption can therefore have global consequences.

But the latest diplomatic developments are giving traders an increasingly plausible alternative scenario:

The strait reopens, ships return, and some of the emergency premium disappears.

Oil markets are reacting before any final deal has been completed.

Iran and Oman are reportedly working on final details of an agreement related to control of the Strait of Hormuz, after Iran's Revolutionary Guards said the two countries had agreed on how the waterway would be shared.

At the same time, Qatar's prime minister is heading to Iran for renewed diplomatic talks aimed at ending the conflict, which is approaching its sixth month.

That does not mean a settlement is guaranteed.

But markets rarely wait for certainty.

They trade probabilities.

The probability of normalized shipping has increased.

As that probability rises, investors have less reason to hold the same amount of protection against a catastrophic supply disruption.

The result is lower crude prices.

The Strait of Hormuz is not simply another shipping lane.

It is a gateway through which massive quantities of energy move from the Gulf to the rest of the world.

Saudi Arabia, Iraq, the United Arab Emirates, Qatar, Kuwait and other major energy producers rely on maritime routes in the region.

When tanker traffic is disrupted, the global oil system effectively loses access to some supply even if the crude itself continues to be produced.

That distinction is central.

A supply disruption can occur because oil production falls.

Or it can occur because oil cannot be transported.

The second problem can sometimes be resolved faster through diplomacy.

That is why even the possibility of a reopening has such a large impact on prices.

There are early signs that the market's optimism is not entirely theoretical.

Shipping traffic through the strait increased slightly on Wednesday, according to data cited in the Reuters report.

That is still a long way from normal conditions.

But small changes matter when the market is searching for evidence of stabilization.

If tanker movements continue to rise, traders could become increasingly confident that supply disruptions are easing.

That could put additional pressure on Brent and WTI.

Conversely, any fresh security incident or breakdown in negotiations could send prices sharply higher.

The result is an oil market that remains extremely sensitive to diplomatic headlines.

Tim Waterer, chief market analyst at KCM, said oil had weakened because markets were increasingly pricing the possibility of a deal that would increase shipping through Hormuz. He noted that a fuller reopening could lead to another leg lower in crude, although prices were unlikely to return to pre-conflict levels immediately.

That is an important distinction.

The market is not saying the energy system can instantly return to normal.

It is saying the probability of the worst-case scenario has fallen.

That is enough to remove part of the price premium.

The remaining premium reflects continued uncertainty.

Investors know the nuclear dispute between Iran and the West has not been resolved.

They know diplomatic discussions can fail.

And they know Tehran understands the strategic value of the strait.

The geography of Hormuz gives Iran unusual influence.

The country does not need to control every barrel flowing through the waterway to affect the global energy market.

The mere possibility of restricted shipping can be enough to raise insurance costs, increase freight rates and encourage traders to bid up crude futures.

That creates leverage.

Priyanka Sachdeva, head of market insights at Phillip Nova, said Iran understands the importance of its geographical position and the leverage the strait gives it, while the risk of prolonged uncertainty remains.

That is why traders are likely to continue paying attention to military and diplomatic developments even as oil prices fall.

The decline reflects improving expectations.

It does not represent the disappearance of risk.

If the decline continues, the benefits can spread far beyond financial markets.

Cheaper crude can eventually translate into lower gasoline prices.

It can reduce transportation costs.

It can lower energy expenses for manufacturers.

And it can ease inflationary pressure.

That last point is particularly important because global central banks have been wrestling with the tradeoff between inflation and growth.

A geopolitical oil shock can complicate monetary policy.

If crude falls instead, central banks gain more room to focus on underlying economic conditions.

The latest decline therefore carries potential macroeconomic significance.

For producers, the same development is less welcome.

Higher crude prices increase revenue and can expand profit margins.

A sustained decline reduces those benefits.

Companies that invested heavily to increase production may discover that lower prices make some projects less attractive.

Governments dependent on energy revenues can also face budget pressure.

That is why oil markets always have winners and losers.

Consumers may celebrate lower crude.

Producers may prefer the geopolitical premium to remain.

Despite the recent losses, Brent remains in the mid-$80s and WTI around the low-$80s.

Those are still elevated prices compared with much of the recent pre-conflict period.

That suggests the market continues to assign some probability to ongoing disruption.

A full normalization could push prices lower.

But that outcome would require more than optimistic headlines.

It would require sustained shipping traffic.

It would require confidence in the security of the waterway.

It would require diplomatic progress.

And it would require evidence that producers and consumers can return to more predictable operating conditions.

A prolonged decline could also change the calculations of major producing countries.

When prices are high, producers may be tempted to maximize output.

When prices fall, they have stronger incentives to protect market prices through production discipline.

That can create a new balancing mechanism.

If diplomatic progress causes crude to fall too rapidly, producer responses could eventually provide support.

This is one reason oil markets rarely move in a straight line for long.

Supply, demand and geopolitics constantly push against each other.

Oil is priced globally in U.S. dollars.

The dollar's recent recovery therefore creates another influence on the commodity market.

A stronger dollar can make dollar-denominated commodities more expensive for holders of other currencies, potentially weighing on demand at the margin.

At the same time, changing interest-rate expectations can influence financial-market positions in oil futures.

That means the crude decline is occurring within a much broader macroeconomic environment.

The market is watching not only Iran and Hormuz, but also U.S. inflation, Federal Reserve policy and global growth.

The oil market's current optimism could unravel quickly.

A failed diplomatic meeting could do it.

A major incident involving a tanker could do it.

A renewed military confrontation could do it.

Or Iran could decide to use the strait more aggressively as leverage.

Any of those developments could return the geopolitical premium to crude almost immediately.

That is why traders remain cautious even while prices fall.

The market has not forgotten what caused the premium in the first place.

The fact that Brent is heading for a fourth straight daily decline is itself meaningful.

It suggests the market is steadily revising its assessment of supply risk.

WTI's fifth consecutive daily loss tells a similar story.

Investors are no longer paying the same price for protection against a prolonged energy blockade.

The question is whether that repricing will continue.

If negotiations make further progress and shipping rises, crude could move materially lower.

If diplomacy stalls, prices could stabilize.

If the crisis deteriorates again, the entire move could reverse.

That may be the most important shift.

Earlier in the crisis, traders were focused primarily on physical disruption.

Now they are increasingly focused on negotiations.

That change tells us the market believes diplomacy has moved from an abstract possibility to a plausible mechanism for restoring energy flows.

It is still an uncertain process.

But the price action shows that traders are willing to bet on it.

For consumers, that is potentially encouraging.

For central banks, it could remove some inflation pressure.

For producers, it threatens to erase part of the premium created by geopolitical risk.

And for traders, it means one thing above all:

The next major oil move may depend more on what diplomats say than on what drillers produce.

Until the Strait of Hormuz is demonstrably operating normally, however, the market will continue to price risk.

Thursday's decline is therefore not the end of the oil crisis story.

It is evidence that investors are beginning to believe the crisis may have a way out.
