Brent below $100 has calmed markets, but depleted oil inventories and unresolved Hormuz disruption leave inflation and growth risks alive.

Brent crude below $100 has given markets a measure of relief. It has not removed the oil risk.

Reuters reported on June 5 that global oil inventories are running dangerously low as a deal to reopen tanker traffic through the Strait of Hormuz remains elusive. The warning matters because crude prices have been restrained partly by buffers that can fade: prewar oversupply, strategic stockpiles, rerouted flows and weaker import demand from some buyers.

Those cushions explain why the market has not suffered a larger immediate shock despite disruption around a route that normally handles a large share of global oil and liquefied natural gas trade. But inventory buffers are finite. If tanks draw down further, the next supply scare could move prices more violently than the headline level of Brent currently suggests.

The macro channel is straightforward. Higher oil prices feed into gasoline, transport costs, manufacturing margins and inflation expectations. That can push bond yields higher and make central banks less willing to ease. For equity markets already sensitive to rate expectations, an oil spike would be a double hit: weaker growth and stickier inflation.

Energy analysts are also watching the physical market, not just futures. Paper prices can fall on hopes of diplomacy, but refiners and shippers still care about actual cargo availability, insurance costs, routes and delivery timing. A political statement about reopening Hormuz would not instantly normalize barrels that have been delayed, rerouted or withheld.

Investors have been trained to read oil shocks as temporary if supply can be replaced quickly. The current risk is that replacement capacity and stored barrels are thinner than they look. That makes the market more exposed to another escalation, even if the visible price has cooled.

The lesson is not that crude must surge tomorrow. It is that sub-$100 Brent can coexist with a fragile energy system. If inventories keep falling, oil may return from background risk to the main driver of inflation, bonds and equity valuations.
