WASHINGTON — New research released on Wednesday found that lower-income Americans cut back on gas use a lot in the month after the Iran war, but prices that went up made them spend more at the pump, which made the economy's economic inequities worse.
The Federal Reserve Bank of New York said that higher-income consumers spent more on petrol but didn't cut back on their use as much. People with middle incomes fall somewhere in the middle.
The survey found that the differences in how each category reacted were bigger than they were in 2022, when gas prices went substantially after Russia invaded Ukraine. Four years ago, households with higher incomes cut back on their gas use more than they did in March. In 2022, on the other hand, people with lower incomes probably got greater help from government stimulus programs. Since then, the value of the stocks and real estate owned by wealthier families has gone up a lot as well.
The numbers show that the rise in petrol prices has made the "K-shaped economy" worse, as many economists put it. The K-shape label means that rich Americans are still doing well but poor Americans are falling behind. Even though the unemployment rate and economic growth are mostly good, the different results can help explain why most Americans are typically negative about the economy.
Researchers at the New York Fed said, "We find that households had very different experiences with gasoline spending." "Gasoline prices rose sharply in March, which led to a K-shaped pattern in gasoline consumption. This means that high-income households used gasoline faster than low-income households."
According to government data on consumer costs, petrol prices went up nearly 25% between the start of the Iran conflict on February 28 and the end of March. The New York Fed says that overall gas use went down by 3% that month. Gas costs have gone up 50% since the battle started on Tuesday.
The survey found that poorer households, who are those that make less than $40,000 a year, used 7% less gas yet still paid 12% more for it in March. Households with incomes of $125,000 or more a year spent 19% more on gas in March, but they used 1% less gas overall. The report didn't give any numbers for middle-income people.
The numbers show that lower-income Americans are driving less, maybe by carpooling, utilizing public transit, or consolidating errands into fewer trips. Richer Americans, on the other hand, have had to make minimal changes, if any.
According to the New York Fed data, total expenditure at gas stations rose 15% in March compared to the month before. If people keep spending more on petrol, they'll have less money to spend on other things, which will lower overall inflation-adjusted spending and slow down the economy. There are only a few evidence that this is happening so far. People in the US do spend less on gas than they did in the past since cars are now more fuel-efficient.
The government announced last week that consumer expenditure, adjusted for price adjustments, went up 0.2% in March, which is a little less than the 0.3% growth in February.
But there is proof that the rise in petrol prices is a huge problem for many individuals with low incomes. Last week, the Bank of America Institute produced a different analysis that said that one-tenth of the poorest one-third of households now spend 10% of their salaries on petrol. The number is far higher than the average for higher-income households, who only spend 2.7% of their income on petrol.
The Institute's statistics, which come from anonymous testimonies of its clients, also showed that higher gas prices have caused some people to spend less on non-essentials, which are things that aren't groceries, gas, or utilities. In March, the yearly growth in discretionary expenditure by poorer households slowed down from February. For middle- and upper-income households, it went up.
