Brent oil slides to $70 as US-Iran ceasefire eases supply concerns

The entire war premium has now evaporated.
Oil prices have fully retreated to prewar levels as the ceasefire agreement shifts market expectations.

For the first time since hostilities began, the price of oil has retreated to where it stood before the war — a quiet but consequential signal that markets believe the worst may be over. Brent crude fell to $70.65 a barrel as a US-Iran ceasefire dissolved the fear premium that had driven prices up by as much as 70 percent over four months. The Strait of Hormuz, that ancient chokepoint through which a fifth of the world's oil passes, is moving again, and with it, the immediate threat of an inflation spiral has receded. What remains is the harder, slower work of turning a ceasefire into a peace.

  • Brent crude shed its entire wartime gain in a matter of days, falling 1.29% to $70.65 — a market verdict that the geopolitical crisis has, for now, been priced out.
  • The Strait of Hormuz, which became a genuine flashpoint during four months of conflict, is seeing steadily recovering traffic, and that normalization is doing more to calm traders than any diplomatic statement.
  • Indirect US-Iran talks opened Wednesday in Doha, centering on frozen Iranian assets and Hormuz access — negotiations the market is watching closely even as it has already bet on baseline stability.
  • OPEC+ is expected Sunday to announce a fifth consecutive month of production increases, adding roughly 188,000 barrels per day in August, compounding downward pressure on prices already in retreat.
  • UBS strategist Matthew Carter warns that oil prices remain a live wire for inflation and central bank policy — stability here could spare markets from aggressive Fed rate hikes, but the ceasefire must hold.

Brent crude fell below $70 a barrel for the first time since before the fighting began — a milestone that signals how completely the market has shed the war premium built up over four months of conflict. The benchmark dropped 1.29 percent to $70.65 on Thursday, and by Friday had fully retreated to prewar levels. West Texas Intermediate followed, falling 1.44 percent to $67.59.

The driver is the ceasefire between Washington and Tehran. Oil had surged as much as 70 percent during the conflict as traders braced for supply disruptions from one of the world's largest producers. That entire gain has now evaporated. The two sides agreed to a 60-day ceasefire and have begun negotiating a permanent settlement, fundamentally shifting how the market prices risk.

At the center of traders' attention is the Strait of Hormuz, through which roughly a fifth of global oil exports normally flows. Traffic through the strait has been steadily recovering, and that normalization is doing more to ease supply fears than almost anything else. Indirect technical talks between the US and Iran opened Wednesday in Doha, focused on frozen Iranian assets and Hormuz access — though the market appears to have already priced in a baseline assumption that some form of stability will hold.

UBS strategist Matthew Carter noted what is truly at stake: if current price levels persist, the immediate risk of an inflation shock recedes, and with it, the pressure on central banks to raise interest rates aggressively — consequences that reach far beyond energy markets.

On Sunday, OPEC+ is expected to announce its fifth consecutive month of production increases, raising output by roughly 188,000 barrels per day in August. Less geopolitical risk, recovering chokepoint flows, and coordinated supply increases all point to a market that has moved past its crisis moment. What remains uncertain is whether the ceasefire holds, whether Doha produces a durable agreement, and whether OPEC+ can manage the transition to lower prices without triggering new disruptions.

Brent crude oil dropped below $70 a barrel for the first time since before the fighting started, a milestone that marks how thoroughly the market has shed the war premium that once gripped energy prices. On Thursday morning, the benchmark that tracks two-thirds of the world's oil supply fell 1.29 percent to $70.65 a barrel. By Friday, prices had fully retreated to prewar levels. West Texas Intermediate, the US crude gauge, was down 1.44 percent to $67.59 a barrel.

The collapse in prices traces directly to the ceasefire agreement between Washington and Tehran. During the four-month conflict, oil surged as much as 70 percent as traders braced for supply disruptions from one of the world's largest producers. That entire gain has now evaporated. The two sides agreed to a 60-day ceasefire and have begun negotiating a permanent settlement, which has fundamentally shifted how the market prices risk.

What matters most to traders right now is the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world's oil exports normally flows. Before the war, this chokepoint was already fragile; during the conflict, it became a genuine flashpoint. Traffic volume through the strait has been steadily recovering, and that normalization is doing more to ease supply fears than almost anything else. The market can see with its own eyes that energy is moving again.

Indirect technical talks between the US and Iran began Wednesday in Doha, with two central issues on the table: the release of frozen Iranian assets and access to the Strait of Hormuz. These negotiations are being watched closely, though the market seems to have already priced in a baseline assumption that some form of stability will hold. Crude inventories fell by about two million barrels last week, which was less than expected, and that smaller-than-anticipated draw also contributed to downward pressure on prices.

Matthew Carter, a strategist at UBS, framed what's at stake: investors and central bankers are acutely sensitive to how Middle East developments ripple through oil prices, inflation, and bond markets. If current price levels persist, the immediate risk of an inflation shock recedes, and with it, the pressure on central banks to raise interest rates aggressively. That matters far beyond energy markets.

The Organization of the Petroleum Exporting Countries and its allies are preparing to announce production decisions on Sunday. Sources tell Reuters that OPEC+ is expected to raise output quotas by roughly 188,000 barrels per day in August, matching July's increase. This would mark the fifth consecutive month of production hikes as the group tries to balance a market where prices are falling and supply concerns are fading. Last month, OPEC itself lowered its demand forecast for the year a second time, though officials expressed confidence that the global economy would remain resilient despite the disruption from the war.

The arithmetic is straightforward: less geopolitical risk, more oil flowing through critical chokepoints, and coordinated production increases from the world's largest suppliers all point toward a market that has moved decisively past the crisis moment. What remains to be seen is whether the ceasefire holds, whether the Doha talks produce a durable agreement, and whether OPEC+ can manage the transition to a lower-price environment without triggering another round of supply shocks.

Investors and central bankers remain highly sensitive to fast-moving Middle East developments and their consequences for oil prices, inflation, and bonds.

Why did oil prices fall so sharply once the ceasefire was announced? Wasn't the market already pricing in some possibility of peace?

Model

The market had been holding a war premium—a cushion of extra cost built in for the risk that things could get worse. Once the ceasefire was real and talks began, that premium evaporated almost overnight. It's the difference between hoping for peace and actually having it.

Inventor

The Strait of Hormuz seems to be the real barometer here. Why is traffic volume so important?

Model

Because it's the physical proof that supply isn't being choked off. During the war, that strait was a genuine chokepoint—a place where a single incident could have cascading effects. Now that ships are moving through again, traders can see the risk has actually diminished, not just theoretically but in real time.

Inventor

If OPEC+ is raising production five months in a row, doesn't that suggest they're worried about oversupply?

Model

They're managing a transition. Prices are falling, demand forecasts are being revised down, and they need to avoid a crash that would hurt their own revenues. Steady, modest increases are their way of letting the market adjust gradually rather than all at once.

Inventor

What's the connection between oil prices and interest rates that Carter mentioned?

Model

If oil stays cheap, inflation stays contained. If inflation stays contained, central banks don't need to raise rates aggressively. That matters to everyone—borrowers, savers, bond holders. Oil prices ripple through the entire financial system.

Inventor

Is the ceasefire actually holding, or is the market just being optimistic?

Model

There was a flare-up last week, and prices barely moved. That suggests the market has already decided the ceasefire is durable enough to bet on. But the talks in Doha are still indirect—the two sides aren't even in the same room yet. That's the real test ahead.
