Markets bet Trump can’t afford $100 Oil as US conducts ‘self-defence strikes’

Oil is becoming the biggest constraint on Washington’s Iran strategy.

As Brent crude pushes back toward $100 a barrel following fresh US strikes inside southern Iran, financial markets are increasingly betting the White House cannot afford a prolonged energy shock without risking renewed inflation, weaker consumer sentiment and broader economic fallout, says Nigel Green, CEO of global financial advisory deVere Group.

“Markets increasingly believe economic pressure will force diplomacy to move faster than military escalation,” says Nigel Green.

“Washington can project strength militarily, but sustained triple-digit oil creates economic consequences the US simply cannot ignore.”

The comments come after fresh US strikes on Iranian targets, which they called “self-defence”, and renewed threats around the Strait of Hormuz pushed energy markets back into focus.

At the same time, President Donald Trump said talks with Tehran were “proceeding nicely,” while warning failure to secure an agreement could send the situation “back to the battlefront and shooting, but bigger and stronger than ever before.”

Yet despite the military escalation and increasingly aggressive rhetoric, oil has failed to enter full panic mode and equities remain relatively resilient — a sign investors still believe diplomacy ultimately wins because the economic consequences of sustained triple-digit crude are too severe for Washington to tolerate.

“Markets are treating escalation as negotiating leverage, not a signal of prolonged war,” says Nigel Green.

“That distinction matters enormously for investors.”

The deVere CEO says markets increasingly believe the White House wants negotiating leverage, not a prolonged conflict that sends oil decisively above $100 and reignites inflation across the global economy.

A sustained move above $100 crude risks feeding directly into gasoline prices, inflation expectations and Treasury yields — three pressures markets are watching simultaneously.

“Expensive energy acts like a tax on households and businesses,” notes Nigel Green.

“It weakens consumption, pressures corporate margins and creates renewed inflation risks at exactly the wrong moment.”

The inflation implications are especially important for investors already highly sensitive to interest rates, borrowing costs and bond yields.

Another oil-driven inflation spike could quickly tighten financial conditions globally and create fresh instability across equities, debt markets and currencies.

“Bond markets are becoming an increasingly powerful geopolitical constraint,” says Nigel Green.

“Investors are watching Treasury yields almost as closely as military developments in the Gulf because another major energy shock risks reigniting inflation fears very quickly.”

Reports suggesting a potential US-Iran agreement may be close have reinforced the broader market view that both sides remain under mounting pressure to secure a deal despite ongoing military confrontations.

Media reports, citing senior US officials, claimed on Monday that negotiations were “95% there,” while Secretary of State Marco Rubio stressed that the Strait of Hormuz “has to be open, one way or the other.”

Nigel Green argues markets are increasingly signalling confidence that economic realities will ultimately outweigh military escalation.

“The White House understands sustained $100-plus oil damages consumer confidence, complicates monetary policy and threatens economic momentum,” he says.

“For all the military posturing, the economic incentives still point toward eventual de-escalation.”

Nigel Green says investors increasingly believe economics — not military rhetoric — will determine how the crisis evolves from here.

“Financial markets are sending a clear signal: the global economy cannot absorb a prolonged oil shock without consequences,” says Nigel Green.

“Investors increasingly believe economic reality will ultimately force a deal before escalation spirals into something far more damaging for markets, consumers and the broader US economy.”
