US October Core CPI Rises 0.3% MoM, Exceeding Expectations; December 50bp Rate Hike Bets Surge

TREE NEWS reports: US inflation data for October came in stronger than expected, reinforcing expectations that the Federal Reserve will raise interest rates at its December meeting. The Labor Department reported Tuesday that the consumer price index (CPI) rose 0.4% month-over-month, above the 0.3% consensus. Core CPI, which excludes food and energy, increased 0.3% from the prior month, also exceeding the 0.2% forecast. Due to a data collection disruption during last October’s government shutdown, the bureau did not publish year-over-year changes.

Following the release, US equity futures fell sharply, gold dipped, and market-implied odds of a 25-basis-point hike in December jumped to nearly 100%, while bets on a 50-basis-point move also increased. Of the 70 analysts surveyed, only one had predicted such a strong inflation reading, underscoring the broad surprise.

This is the last CPI report Fed officials will see before their December 8-9 policy meeting. Ahead of the data, Fed Governor Christopher Waller had explicitly stated that if core CPI rose 0.3% or more month-over-month, the Fed might need to consider a larger 50-basis-point hike.

Hawkish Rhetoric Sets the Stage, Markets Under Pressure

Before the CPI release, Waller delivered a hawkish message in London early Tuesday, pushing Treasury yields off their lows—particularly at the short end—strengthening the dollar, and weighing on equities. Waller said he would favor a 25-basis-point hike if October inflation showed improvement on a monthly basis. But he warned that if core CPI rose 0.3% or more, a stronger policy response might be needed. “In that case, I think the December meeting should consider a 50-basis-point hike,” he said. The data ultimately landed right in Waller’s threshold for “stronger policy action,” making the debate between 25 and 50 basis points the market’s central focus.

Housing, Food, and Energy All Push Prices Higher

October’s inflation increase was driven by multiple components. Housing costs rose 0.3% month-over-month and accounted for more than 30% of the overall increase, making it the largest contributor. Food prices climbed 0.5%, with both groceries and dining out showing notable gains. Energy prices rose 0.7%, and gasoline prices increased 1.0% after seasonal adjustment, extending September’s strong advance. Used car and truck prices fell 1.2%, providing some offset. Notably, due to the October government shutdown that disrupted data collection, the bureau did not publish year-over-year figures; Bloomberg backfilled historical data using extrapolation methods.

Inflation Remains Elevated, Policy Path Divergent

The data comes after the Fed raised rates by 25 basis points in September and held steady in October, reaffirming the policy direction. The Iran war, tariffs, and a data center construction boom have continued to fuel inflation this year, with price pressures showing little sign of easing ahead of the midterm elections. On a positive note, crude oil and refined product prices have fallen noticeably since the CPI collection period, suggesting energy’s contribution to inflation may be near its peak and subsequent data could moderate. However, sticky core inflation remains the main source of pressure on Fed decision-making. With Waller’s public stance, the size of the December hike will depend largely on whether other economic data provide more signs of easing.

Key Takeaways for Investors

• Rate-sensitive assets face renewed pressure: The stronger core CPI reading raises the probability of a 50-basis-point hike, which could weigh on growth stocks, long-duration bonds, and rate-sensitive sectors such as real estate and technology.
• US dollar may strengthen further: Hawkish Fed expectations typically support the dollar, potentially adding pressure on emerging market currencies and dollar-denominated commodities.
• Crypto remains correlated with risk sentiment: Digital assets have shown sensitivity to Fed policy shifts; a more aggressive tightening path could dampen risk appetite in the near term.
• Watch energy prices: The recent decline in oil prices may offer some relief in future inflation reports, but core stickiness suggests the Fed is unlikely to pivot soon.
• Volatility likely to persist: With the December meeting approaching and only limited data before then, markets may remain jittery, creating both risks and opportunities for active investors.
