Citadel Securities has warned that the Federal Reserve may need to resume monetary tightening later this year as inflation pressures remain elevated across the U.S. economy. The firm’s latest outlook suggests that Fed rate hikes could begin as early as September 2026 if inflation continues to exceed policymakers’ targets.
The forecast comes ahead of the Federal Open Market Committee meeting on June 17. Market participants widely expect officials to leave interest rates unchanged. However, Citadel believes investors should focus on future policy signals rather than the immediate decision.

Persistent Inflation Raises Policy Concerns
Citadel’s Head of Macro Strategy, Frank Flight, stated that inflation risks continue to build despite lower energy prices. According to the firm’s analysis, inflation has spread into broader sectors of the economy rather than remaining concentrated in commodities.
Flight wrote that the economy faces the risk of entering a “hysteretic equilibrium,” where temporary shocks create lasting inflationary effects. Citadel identified strong labor markets, accommodative financial conditions, and supply-chain disruptions as major factors supporting price growth.
Recent economic indicators support those concerns. Headline Consumer Price Index inflation reached 4.2% in May, while Producer Price Index inflation climbed to 6.5%. Citadel also noted that a larger share of core CPI components now records annual increases above 3%, suggesting inflation remains widespread.
AI Investment Boom Adds New Demand Pressure
Citadel also highlighted the growing impact of artificial intelligence spending on the economy. The firm estimates AI-related capital expenditures could reach approximately $750 billion in 2026 before rising to $1.25 trillion in 2027.
Large investments by companies such as OpenAI, Anthropic, and SpaceX continue to increase demand for infrastructure, computing resources, and skilled labor. As a result, AI development may contribute additional inflationary pressure during the coming years.
Against this backdrop, Citadel expects Federal Reserve officials to maintain a hawkish stance. Flight stated, “We think the risks skew to a rate hike at the September meeting.” The firm also expects policymakers to remove any remaining easing bias from future projections.
Markets Increase Bets On Fed Rate Hikes
Citadel’s forecast aligns with shifting market expectations. Kalshi prediction market data currently assigns a 60% probability that the Federal Reserve will raise interest rates before July 2027. Expectations for tightening have increased steadily in recent months.

Meanwhile, a recent Bank of America fund manager survey found that nearly 40% of respondents expect at least one rate increase within the next year. That figure stood at just 16% one month earlier.
BNP Paribas has also revised its outlook. The bank now expects three Fed rate hikes beginning in December, citing persistent inflation and continued labor market strength.
Citadel projects potential rate increases in September and December 2026, followed by another move in March 2027. The firm warned that higher borrowing costs and tighter liquidity conditions could create challenges for risk assets, including Bitcoin and the broader cryptocurrency market, if investors increasingly price in future Fed rate hikes.
