Consumers hit by one-two punch of oil and rates from Iran war. The estimated bill is $1,700 per household

• Gas prices exceeded $4.32 per gallon (up 36% year-over-year) and diesel jumped 70%, with consumers collectively spending over $121 billion extra on energy since the conflict began
• The 10-year Treasury yield hit 19-year highs, pushing mortgage rates above 7% for the first time in over a year and threatening affordability for homes, cars, and other big-ticket purchases
• The U.S. savings rate has fallen to levels rarely seen since the Global Financial Crisis as consumers deplete reserves to offset negative real wage growth, raising concerns about future spending sustainability

Summary

U.S. consumers face significant financial strain from escalating conflict with Iran, with households bearing an estimated cost of $1,760 since the war began, according to Moody's Analytics (as of September 11).

Key Cost Breakdown:

• $930 from higher energy prices (gasoline, diesel, jet fuel)
• $425 from increased interest rates
• $405 from military spending (via debt or taxes)
• Total additional energy spending: $121 billion across all U.S. consumers

Energy Impact:

Crude oil prices surged, with gasoline averaging $4.32/gallon (up 6% month-over-month, 36% year-over-year). Diesel prices climbed roughly 70% year-over-year. Labor Day travelers faced record-high prices. Energy prices in the CPI jumped 23% in August versus prior year. Nearly 29% of consumer sentiment survey respondents mentioned gas prices in September, up from 12% and 6% in 2024 and 2025.

Interest Rate Pressure:

The 10-year Treasury yield hit 4.973%, its highest level in 19 years and roughly one percentage point above year-ago levels. The 30-year mortgage rate exceeded 6% for the first time in over a year. Some 44% of consumers expect borrowing costs to rise further. The Fed faces 92%+ probability of hiking rates soon—its first increase in three years.

Consumer Response:

Higher costs have erased benefits from tax refunds under President's tax cuts. Real wage growth turned negative as inflation outpaces income. The U.S. savings rate fell to levels rarely seen since the 2008 financial crisis. Credit card debt reached $1.26 trillion in Q2, near record highs.

Market Implications:

Economists warn consumer spending—the majority of GDP—may decline as households exhaust savings, potentially triggering broader economic slowdown.
