Brent crude just topped $116 a barrel. Here's how rising oil prices affect everything from gas stations to grocery stores — and what to watch next.
Brent crude topped $116 a barrel on Monday as the conflict in the Middle East intensified. Oil is now up over 50% in a single month. If that sounds dramatic, it's because it is — and its effects reach far beyond the energy sector.
Here's how an oil price shock actually works, step by step.
The ongoing conflict between the U.S., Israel, and Iran has disrupted shipping through the Strait of Hormuz, one of the world's most important oil chokepoints. About 20% of global oil supply passes through it. With that route under threat, markets are pricing in the possibility of prolonged supply disruptions.
Brent crude surged more than 3% at the Monday open to $116.43, heading for a record monthly gain. WTI crossed $101.
An oil shock doesn't stay in the oil market. It moves through the economy in waves:
Wave 1: Energy costs jump. Gas prices rise at the pump. Heating and electricity bills go up. Airlines, trucking companies, and manufacturers all see higher costs.
Wave 2: Those costs get passed on. Companies don't absorb higher fuel costs for long. They raise prices — on shipping, on food, on goods. This is how oil shocks feed directly into inflation. The latest PCE inflation forecast was already revised up to 3.1% for 2026, and that was before this week's spike.
Wave 3: Consumer spending slows. When people pay more for gas and groceries, they have less to spend on everything else. Consumer sentiment just fell to a three-month low. Less spending means slower economic growth.
Wave 4: Markets reprice risk. Investors start pricing in the possibility of recession. The S&P 500 is already down about 8% year-to-date. Asian markets sold off sharply Monday — the Nikkei dropped 2,400 points and the Kospi fell 4%.
This chain reaction — from oil supply disruption to inflation to slower growth to falling markets — is the classic playbook for an oil shock. It happened in the 1970s, in 2008, and in a milder form in 2022.
Three things will determine how this plays out:
Oil shocks are one of the few things that can move every part of the economy at once — from your gas receipt to your 401(k). The current spike is driven by a real supply disruption, not just speculation, which makes it harder to ignore. Understanding how these waves work helps you make sense of the headlines without panicking.
