William Stern on the Strait of Hormuz, Oil Prices, Inflation, and Geopolitical Risk

Mar 10, 2026

Rising geopolitical tensions around the Strait of Hormuz are drawing renewed attention to the stability of global energy markets and the potential economic impact of supply disruptions. A large share of the world’s oil moves through this narrow passage each day, making it a key route in international energy trade. Any disruption in this region can quickly affect global oil supply and pricing.

Recent developments have heightened concerns about the vulnerability of this critical passage. Even the possibility of restricted access or delays can lead to sharp reactions in energy markets, as traders and investors anticipate tighter supply conditions. When oil prices rise in response to these risks, the effects are felt far beyond the energy sector. Higher energy costs can influence prices across the board, creating ripple effects throughout the broader economy.

These dynamics also play a key role in shaping inflation trends. Rising oil prices can drive up the costs of running a business, from transportation to manufacturing. Companies often pass those higher costs on to consumers, which can push overall prices up and contribute to inflation. That makes it harder for central banks to keep the economy stable. For this reason, policymakers, investors, and businesses closely watch geopolitical risks that could disrupt energy supplies.

The Cardiff Connection

William Stern, founder of Cardiff, explained that the effects of geopolitical risk in the Strait of Hormuz extend far beyond global energy markets. They also ripple through the operations of businesses large and small. When oil prices spike, small businesses often face immediate cost pressures, from higher shipping and fuel expenses to increased prices for raw materials. Those costs can squeeze margins, delay planned investments, and even affect hiring decisions.

Stern noted that central banks can respond to inflation, but when price increases stem from physical supply constraints, policy tools can only do so much. That makes it especially important for small business owners to understand how these global developments might influence their cash flow and planning.
