Federal Reserve to Hike Interest Rates in December 2026

Live Poll

Do you believe current economic uncertainty makes this a difficult time to adjust your financial investments?

Citi chief economist Nathan Sheets projects that the Federal Reserve will raise interest rates in December 2026. This forecast follows a period where rising U.S. Treasury yields and volatile oil prices have signaled ongoing inflationary pressures.

Why it matters

Rising long-term Treasury yields and supply chain constraints in commodities like aluminum and fertilizers are forcing economists to reevaluate future monetary policy. These fiscal and geopolitical pressures, compounded by AI-related infrastructure demand, create a challenging environment for business debt and capital investment planning.

Core PCE inflation reached 3.0% in August 2026, with 30 basis points of that figure driven specifically by AI-related demand. Meanwhile, benchmark 10-year Treasury yields have climbed to 5.1% amid concerns over fiscal demand and volatility in oil prices between $100 and $110 per barrel.

The players

Nathan Sheets

Chief economist at Citi who tracks global fiscal and monetary policy trends.

Federal Reserve

The central bank of the United States tasked with managing inflation and interest rate policy.

The details

Corporate investment into AI by hyperscalers is currently a primary driver of inflationary demand, while supply chain pressures continue to affect costs for aluminum, petrochemicals, and fertilizers. With oil prices fluctuating significantly due to the ongoing conflict in Iran, markets are watching for how these combined inputs influence the Federal Reserve. Operators should note that rising Treasury yields reflect broader market concern regarding fiscal sustainability and the potential for a debt-ceiling standoff by mid-2027.

Mid-2027: Potential U.S. debt-ceiling standoff.

Market Landscape

These projections follow a sustained period of market pressure as the Federal Reserve works to bring headline metrics back to its 2 percent inflation target. The emergence of AI-related demand as a measurable component of core inflation marks a significant shift in the factors influencing domestic monetary policy.

Business owners should prepare for higher costs of borrowing and volatile input prices as interest rates trend upward in late 2026. Reviewing variable-rate debt obligations and securing supply chains for energy and industrial materials is prudent given the current macroeconomic uncertainty.

The takeaway

Operators must account for a changing interest rate environment that is increasingly influenced by energy volatility and AI-driven capital demand. Keep a close watch on the Federal Reserve's December meeting minutes to inform 2027 debt and procurement strategies.

What happens next

Businesses should monitor the Federal Reserve's upcoming policy communications for confirmation of the December rate hike. Additionally, finance teams should begin stress-testing capital budgets for a potential U.S. debt-ceiling standoff forecasted for mid-2027.
