Inflation picked up in May, with consumer prices rising 0.5% for the month and 4.2% over the past year — a reminder that the battle against rising prices is not yet over.
The Consumer Price Index, the government’s broadest measure of what Americans pay for everyday goods and services, rose 0.5% in May on a seasonally adjusted basis, according to the latest data. That monthly gain pushed the annual rate to 4.2%, well above the Federal Reserve’s 2% target for stable prices.
Gasoline and shelter — meaning rents and the estimated cost of owning a home — were the primary drivers of the increase. Energy prices tend to move quickly and can have an outsized effect on monthly CPI readings, while shelter costs carry a heavy weight in the index and tend to be stickier, meaning they change slowly over time.
The so-called core index, which strips out food and energy to give a cleaner read on underlying price pressures, rose a more modest 0.2% for the month. Over the past 12 months, core inflation stands at 2.9% — closer to the Fed’s target, but still above it. Policymakers tend to watch core inflation closely because it filters out volatile swings in oil and food prices.
The data matters most for what it signals to the Federal Reserve. When inflation runs above the Fed’s 2% goal, the central bank is under pressure to keep interest rates higher for longer — or even consider raising them further. Higher rates are the Fed’s main tool for cooling demand and slowing price growth, but they also raise borrowing costs for households and businesses.
A 4.2% annual headline rate suggests that while inflation has come down significantly from the peaks seen in recent years, meaningful progress toward the Fed’s target has stalled. Markets and analysts will be watching the next few months of data closely to judge whether May’s reading reflects a one-month blip driven by energy prices or a more durable resurgence in inflation.
The Fed’s next policy meeting will be closely watched for any signals that officials are reassessing their outlook in light of the firmer inflation data.
