CPI Falls Short of Expectations Amid Tariff Uncertainty
Updated June 11, 2025
May’s Consumer Price Index (CPI) revealed a surprise slowdown in inflation, with both headline and core CPI figures missing economist expectations. The headline CPI rose 0.08% while core CPI, which excludes volatile food and energy prices, increased by 0.13%.This miss raises questions about the trajectory of future inflation and the potential impact of ongoing policy changes.
Economists had forecast a 0.17% increase in the headline CPI and a 0.28% rise in core CPI. The actual figures represent a notable deviation, particularly in the core measure. The Federal Reserve is closely watching these indicators as it assesses the need for adjustments to monetary policy.
A meaningful factor in the CPI miss was the slower-than-expected increase in primary rents, which rose 0.21%. Owners’ Equivalent Rent also showed moderation. These two components contributed roughly 5 basis points to the core CPI shortfall.While rent increases are not collapsing, continued deceleration is needed to reach the Fed’s 2% inflation target.

The anticipated inflationary effects of tariffs have yet to fully materialize, particularly in the auto industry. Used car and truck prices fell 0.54%, while new car prices declined 0.29%. This unexpected price decrease may be due to longer-than-expected lags in the manufacturing process or higher demand elasticity.
Despite the decline in auto prices, core goods inflation accelerated to 0.3% year-over-year, up from 0.1% the previous month. Increases in tenants’ and household insurance (0.84%) and motor vehicle insurance (0.68%) contributed to keeping core services inflation at 3.6% year-over-year. airfares, however, experienced a significant decline of 2.74%.
The “Most Favored Nation” policy’s impact on medicinal drug prices is also under scrutiny, as these prices increased 0.54% month-over-month. Core Services less Rent of Shelter, also known as “Supercore,” decreased to 3.11% year-over-year, a positive trend but still above pre-COVID levels.

median CPI also reflected the overall trend, showing the lowest increase since last July at +0.25% month-over-month. Though, underlying trend median inflation remains around 3.5%, suggesting that significant disinflation is unlikely given current fiscal and monetary policies.
Even with the recent CPI miss, the Federal Reserve is unlikely to tighten monetary policy. M2 growth has returned to levels seen during periods of globalization and positive demographics, but these tailwinds are now headwinds. The Fed will continue to monitor inflation data and the impact of tariffs before making any major policy changes.





What’s next
The coming months will be crucial in determining whether the recent slowdown in shelter inflation is a temporary blip or a sustained trend. The impact of tariffs on various sectors, particularly autos, will also be closely watched. If tariff effects remain minimal in the next few months, it could substantially alter the inflation outlook and prompt further analysis from economists and policymakers.
