## The $1,700 war bill
The U.S.-Iran conflict has cost the average household around $1,760 since it began. More than half comes from higher energy costs alone.
## Double squeeze on consumers
Americans face rising oil prices and Treasury yields at the same time. The 10-year yield hit its highest level in 19 years this week.

> Consumers are under a lot of financial pressure
## Energy costs hit hardest
Higher energy prices account for $930 of the household bill. U.S. consumers have spent over $121 billion extra on energy since the war started.
## Interest rates add $425
Rising interest rates since the war began add another $425 to household costs. Military spending adds the final $405 through debt or taxes.
## Gas prices jump 36%
Gas hit $4.32 per gallon on Tuesday, up 36% from a year ago. Crude oil topped $105 per barrel, its highest since mid May.
## Diesel hits record highs
Diesel prices topped $6 per gallon, 70% higher than last year. Companies may pass these trucking costs on to consumers through higher prices.
## Airfare soars 23%
Airfare has jumped over 23% from a year ago, one of the fastest-rising categories. A 20% oil price gain adds about 0.3 points to inflation.
## Mortgage rates top 7%
The 30-year mortgage rate topped 7% for the first time in over a year. Higher yields make homes and cars less affordable for consumers.

> People experience higher interest rates much like they experience inflation. It makes things less affordable.
## Fed likely to raise rates
Markets price in a 92% chance the Fed raises rates Wednesday, its first hike in three years. Most economists expect at least two more increases.
## Tax refunds wiped out
Higher energy costs have erased gains from bigger tax refunds under Trump's bill. Lower-income consumers feel the pain most acutely.
## Savings rates near crisis lows
Americans are drawing down savings to keep spending. The personal savings rate has fallen to levels rarely seen since the financial crisis.
## Something has to give
Inflation is rising faster than income, leaving consumers with negative wage growth. Economists warn spending pullbacks may be coming.

> Costs have gone up and income growth has gone down, so something has got to give.
## Key takeaway

The U.S.-Iran war has cost the average household $1,760 through higher energy costs, interest rates, and military spending.
