Persistent global conflicts in the Middle East and Eastern Europe are costing the US economy an estimated $45 billion annually through elevated energy prices, according to new analysis. While representing only 0.15-0.2% of GDP, this 'war premium' adds $5 to $15 per barrel to crude oil prices, driving up costs for gasoline, diesel, heating, and electricity.

The burden falls disproportionately on low-income households. The bottom 20% of earners spend up to 10% of their income on energy, compared to 5% for the wealthiest. For a family earning $30,000 a year, a spike in gas prices hits twice as hard relative to their budget.

For investors, the ripple effects are clear: higher energy costs translate to persistent inflation, keeping the Federal Reserve on a hawkish path with higher interest rates for longer. The key variable to watch is whether the war premium expands or contracts. Any further escalation in the Middle East, particularly involving major oil producers or the Strait of Hormuz, could push the premium well above the current range.
