Oil Is Falling Fast — But the Real Story Starts Now

The US-Iran peace deal has eased supply fears, but the road to full recovery remains long, creating opportunities across energy, transport and commodity markets.

Oil has now fallen for four consecutive sessions, reaching its lowest level since early March. Brent crude, the global benchmark, dropped below $80 a barrel today — a far cry from the highs above $120 it hit when the conflict was at its worst. Prices are heading toward their longest losing streak of the year, as the expected US-Iran agreement to reopen the Strait of Hormuz raised expectations of recovering supply flows. 

For anyone who has been following the headlines, that drop makes intuitive sense. Peace deal signed, oil flows again, prices fall. But the full picture is considerably more complicated — and understanding it matters if you want to make sense of where energy markets go from here. 

How We Got Here:  

The conflict began in February 2026 when US and Israeli military operations against Iran triggered the effective closure of the Strait of Hormuz — the narrow waterway between Iran and Oman through which roughly one-fifth of the world’s oil supply passes daily. 

Prior to the 2026 conflict, approximately 20 million barrels per day transited the Strait of Hormuz, representing roughly 20% of total global oil supply flows and an even higher share of globally traded LNG. When that flow stopped, the effect was immediate and severe. At approximately 10 to 11 million barrels per day removed from accessible supply, the 2026 Hormuz closure exceeds the supply disruption scale of both the 1973 OPEC embargo and the 1979 Iranian Revolution, making it the largest single-event supply shock in modern oil market history by volume removed. 

Brent crude surged past $120 a barrel. Gasoline futures spiked more than 10% in a single session. Shipping insurance premiums surged. And inflation expectations, which had been cooling in early 2026, ratcheted sharply higher. 

The months that followed were marked by a series of false starts. A two-week ceasefire agreed in April sent oil plunging 15% in a day — then collapsed within 48 hours when IRGC gunboats attacked a merchant vessel attempting transit. Oil markets have been conditioned by a number of false starts. Each headline of progress was followed by renewed uncertainty, keeping prices elevated and volatile. 

What Changed on 14 June 

Since the peace deal announcement on 14 June, WTI crude oil and Brent crude both fell over 5% to around $80 and $83 per barrel respectively — their lowest levels since 10 March. 

The deal, expected to be formally signed in Switzerland this Friday, is structurally different from the earlier ceasefire attempts. The US and Iran are set to sign a memorandum of understanding, with both countries allowing tankers to cross the Strait of Hormuz upon agreement, and the US unopposed to Tehran deploying tankers immediately. 

Crucially, this agreement also carries broader supply implications. Fresh supply from the region is due to replenish refineries across the globe, with higher export quotas from OPEC+ and higher output from the UAE, which left the cartel during the conflict. 

A Roadmap for What Comes Next 

Even with a signed deal on Friday, the physical recovery of oil supply will be gradual.  

Here is the timeline energy analysts are working with: 

19 June 2026 — Peace Accord Signing: The US and Iran are scheduled to formally sign the memorandum of understanding in Switzerland, officially opening transit lanes. 

Mid-July 2026 — Phased Infrastructure Restart: Rystad Energy’s base case assumes initial commercial tanker flows begin navigating shipping security clearances, with partial volumes moving through Hormuz. 

October 2026 — 85% Volume Restoration: Expected physical return of major regional volumes, excluding heavily delayed complex fields. 

January 2027 — Full Field Normalisation: Anticipated timeline for mature fields in Iraq and Kuwait to achieve complete pre-conflict output capacities. 

Who Moves When Oil Falls: The Gainers 

The most immediate beneficiaries of falling oil prices are the industries that run on fuel. 

Airlines sit at the top of that list. Jet fuel is typically an airline’s second-largest operating cost after labour — so when oil drops sharply, the margin relief is direct and significant. On Monday 15 June, United Airlines (NASDAQ: UAL) closed up 3.85% to $119.97, hitting an all-time record high as investors priced in lower fuel costs for the summer travel season. Delta Air Lines (NYSE: DAL) also gained 1.22% on the same day. 

Closer to home, Singapore Airlines (SGX: C6L) is equally exposed to this dynamic. SIA closed at S$7.17 on 16 June, up 2.43% on the day. Analysts have noted that softer oil prices will help mitigate rises in other operating costs for SIA, which has been navigating a more challenging earnings environment following its Air India investment. The stock carries a forward dividend yield above 6%, with the next dividend carrying an ex-date of 11 August 2026 and a payment date of 28 August 2026. 

Cruise lines are arguably even more sensitive to fuel prices than airlines, given the sheer volume consumed running large vessels continuously. Carnival Corp (NYSE: CCL) closed up 3.22% to $30.12 on 16 June, while Norwegian Cruise Line (NASDAQ: NCLH) closed at $20.14. Royal Caribbean (NYSE: RCL) also gained ground. These companies had been navigating compressed margins throughout the conflict — the combination of falling fuel costs and reopening Middle East travel routes provides a meaningful tailwind heading into peak summer season. 

The Other Side: Energy Stocks Feel the Pressure 

The flip side of falling oil is straightforward. Companies whose revenue is directly tied to the price of a barrel face headwinds. 

ExxonMobil (NYSE: XOM) closed at $140.92 on 16 June, down approximately 4.1% on the day and about 11% over the past month. Chevron (NYSE: CVX) fared similarly, closing at $180.40, a decline of 3.64% on the day. Bank of America recently upgraded ExxonMobil to Buy on the back of its pullback, reflecting that both remain strong long-term businesses — but in a falling oil price environment, near-term revenue per barrel headwinds are difficult to argue against. 

On the SGX, Sembcorp Industries (SGX: U96) presents a more nuanced picture. Unlike a pure-play oil producer, Sembcorp’s energy business is heavily tied to the Singapore Spark Spread — the margin between local electricity prices and the cost of imported LNG. When the Strait of Hormuz was closed, global LNG prices spiked sharply, squeezing power generation margins and raising input costs for Singaporean energy providers. The reopening of Hormuz relieves those LNG import cost pressures directly, which is broadly positive for Sembcorp’s power generation business rather than a headwind. The company is also actively transitioning toward renewables and clean infrastructure, further insulating it from conventional oil price dynamics over the medium term. 

Why Oil Is Still Above Pre-War Levels — And Could Stay There for a While 

Here is the part that gets lost in the headlines: prices nonetheless remain more than 20% above pre-war levels. Unlike a fear-driven risk premium that unwinds with the headline, this elevated base reflects real and lasting structural damage to supply that positive developments alone cannot repair. 

The physical infrastructure along the Gulf is damaged. Refineries, pipelines, and terminals were struck during the conflict, and restarting them takes time. Recovery timelines vary significantly by country and shut-in conditions. Producers that executed orderly shutdowns may resume within days to weeks. Iraq, however, faces a recovery window of up to nine months, according to Wood Mackenzie analysis. 

Under Rystad Energy’s base case scenario, a phased reopening from mid-July 2026 would restore approximately 85% of lost volumes by October 2026, with full recovery of Iraq and Kuwait’s mature fields extending into January 2027. 

There is also the question of tanker availability and shipping insurance — all of which normalise slowly. Tanker day rates typically increase 300–400% whilst insurance premiums surge 500–800% during recovery phases. These economic factors can delay recovery even when production capacity becomes available. 

And then there is the strategic reserve question. The US Strategic Petroleum Reserves had fallen to a 43-year low during the conflict. Rebuilding those reserves will itself require sustained buying, providing a floor under demand. 

The Bottom Line 

The peace deal is genuine progress, and oil’s four-day slide reflects that. But the market is not simply unwinding a fear premium — it is repricing around a supply recovery that will take months, not days, to materialise fully. Prices remain more than 20% above pre-war levels, and the structural damage to Gulf energy infrastructure means the road back to pre-conflict supply levels is measured in quarters, not weeks. 

For the stocks caught in the middle — airlines, cruise lines, and energy names on both sides of the SGX and US markets — the direction of oil from here is the single most important variable to watch. 

Trading the Next Chapter of the Oil Story

As volatility continues to shape the energy landscape, traders may find opportunities on both sides of the market. Whether you’re looking to gain exposure to global oil majors such as ExxonMobil and Chevron, energy transition players like Sembcorp Industries, or broader oil price movements through energy-related products, staying positioned for the next phase of the oil story could be key. With the recovery of global supply expected to unfold over several quarters, energy markets are likely to remain active well into 2027.
