US inflation climbed sharply in March, with consumer prices rising 0.9% from the previous month and 3.3% over the year, according to new data released on Friday.
The increase in the consumer price index, or CPI, marks the largest monthly jump in nearly two years. It is also the first official reading showing how the war with Iran is beginning to affect prices paid by US consumers.
Energy and supply concerns
The latest figures come amid growing uncertainty over global energy supplies after Iran blocked the Strait of Hormuz, a vital shipping route through which about a fifth of the world’s oil and gas would typically pass. That development has raised concern about further price pressure in the weeks ahead, especially for fuel and other goods tied to transportation and energy costs.
The March figures add to the unpredictability already facing the economy, which had previously been unsettled by Trump’s tariffs. Together, the trade measures and the conflict have created a more volatile backdrop for inflation, consumer spending and broader market expectations.
What the CPI shows
The consumer price index tracks the cost of a basket of goods and services used by households. It is one of the most closely watched indicators of inflation in the United States, and the latest reading suggests that price pressures accelerated quickly in March.
The 3.3% annual rate indicates that prices remain well above levels seen a year earlier, while the 0.9% monthly increase points to a sudden change in pace. The report offers an early look at how geopolitical tensions may be feeding through to the US economy, particularly through energy markets and supply chains.
Friday’s release is likely to intensify attention on inflation in the coming weeks, as policymakers, businesses and consumers assess whether the shock from the conflict will prove temporary or lead to a more sustained rise in prices.
