The Federal Reserve faces a shifting landscape where a rate hike has evolved from a tail risk into a tangible market expectation. While the baseline scenario still projects rate stability until 2026 followed by a 25 basis point cut in March 2027, the probability distribution has hardened significantly. Market pricing indicates that the likelihood of a rate increase before the December 2026 FOMC meeting has surpassed 60%, with such a move fully factored into expectations by March 2027. Jonathan Millar of Barclays FICC Economic Research noted on May 18 that while their baseline does not anticipate a hike before the end of 2027, the risk of policy rate increases has intensified. This reassessment stems from three distinct pathways: a divergence in long-term inflation expectations, persistent core inflation despite tariff subsidence, and demand outstripping supply due to the AI investment cycle.

The current baseline relies on optimistic assumptions that disruptions in the Strait of Hormuz will resolve quickly and that tariff and energy price pressures will fade, allowing consumer spending to cool.

However, alternative scenarios present a less dovish outlook. Data compiled by Woofun AI shows that the probability of a 25 basis point cut in 2027 stands at 35%, while keeping rates unchanged until the end of 2027 is priced at 30%, and a rate hike carries a 25% probability with a potential range of 50 to 100 basis points. The risk of a recession triggering significant cuts remains at 10%. The most probable outcome is not an immediate hike but a delay in the anticipated easing cycle, driven by cost pressures evident in the ISM manufacturing and services price indices and the New York Fed's Global Supply Chain Pressure Index.

A primary trigger for tightening would be a decoupling of long-term inflation expectations from short-term trends. Policymakers are closely watching the 5-year, 5-year inflation breakeven rate rather than single-month CPI figures. If these metrics rise persistently, it signals a risk to the credibility of the 2% inflation target. Woofun AI notes that while current market-based expectations are elevated, they do not yet indicate a loss of Fed credibility. The danger lies in prolonged disruptions in the Strait of Hormuz and sustained commodity price spikes, which could force the market to question the Fed's willingness to sacrifice growth to meet its inflation mandate. Such a shift would likely prompt a hawkish pivot in policy communications before all data confirms the trend.

The second pathway involves core inflation remaining above the 0.18% monthly threshold required for the 2% annual target, even as tariff impacts wane. Key indicators include the lack of anti-inflationary effects in core commodities and limited cooling in super-core services excluding housing. If trimmed mean or median inflation measures strengthen, it suggests pressures are broadening beyond specific sectors. The critical factor here is duration; a single month of high data is insufficient, but persistence over several quarters would compel the Fed to act. In a scenario where high inflation coincides with strong demand, policy would tilt toward tightening, whereas high inflation with weak demand would create a conflict between the Fed's dual mandates, though the post-2021 threshold for prioritizing price stability remains high.

The third pathway is driven by domestic demand, specifically the accelerating AI investment cycle. Private final consumption has not slowed, and AI-related capital expenditures have surged this year. Woofun AI analysis suggests that if the wealth-generating effects and capital spending associated with AI materialize before corresponding productivity improvements, the result will be a demand surge rather than inflation relief. This contrasts with the Greenspan era, where supply improvements preceded demand responses. Currently, productivity in the non-farm business sector grew nearly 3% in the four quarters ending in the first quarter of 2026, roughly double the pre-pandemic rate.

However, a San Francisco Fed indicator adjusted for utilization rates suggests this growth may be overestimated by 1.5 percentage points, implying apparent supply gains may not support rising demand.

The Fed monitors traditional overheating indicators, including growth exceeding trend levels, unemployment falling below the NAIRU range of 4.0% to 4.3%, and wage acceleration outpacing productivity. While current evidence for wage acceleration is weak, it remains a critical watchpoint. The baseline strategy of holding rates steady until a March 2027 cut hinges on the resolution of energy and supply chain shocks. If these disruptions persist, core inflation and expectations will likely close the window for easing. Real household disposable income has slowed due to job growth deceleration, which should theoretically cool consumption.

However, if AI-driven demand continues to support spending, the Fed will face a difficult decision regarding the adequacy of current policy tightness.

Ultimately, the risk for the Federal Reserve in 2026 is not a simple binary shift from cuts to hikes. Instead, the rate-cut pathway is being compressed by supply shocks, sticky core inflation, and the spillover effects of AI-driven demand. While a rate hike requires more convincing data to justify, it has re-emerged as a serious topic of discussion among policymakers. The convergence of geopolitical instability, persistent inflationary pressures, and a technology-driven demand boom creates a complex environment where the Fed must balance the risks of premature tightening against the dangers of allowing inflation expectations to become unanchored.
