Fed Eyes Rate Hikes as Core PCE Hits 3.1%, Upending Tech Valuation Math

Persistent inflation and hawkish Fed signals threaten rate-cut bets, squeezing AI infrastructure funding and repricing growth stocks ahead of the March 18 FOMC meeting.

Core PCE inflation rose 0.4% in January and 3.1% year-over-year, the highest reading in nearly two years and a full percentage point above the Federal Reserve’s target. Markets entered March pricing one rate cut for 2026. They may now get zero—or worse.

Chief macro strategist Sonu Varghese said the Fed may “start talking about rate hikes later this year” after January’s inflation data showed persistent price pressures even before geopolitical shocks. The shift represents a material repricing of the macro baseline that has powered equity markets since late 2024, particularly AI and rate-sensitive tech names trading at 25x+ forward earnings.

Policy Pivot Gains Traction

Federal Reserve FOMC minutes showed officials discussed possible rate hikes if inflation stays above 2%, reversing the easing bias that dominated late 2025. Headline PCE Inflation was 2.8% in January while core PCE reached its highest level since March 2024, driven by services inflation that remains impervious to higher borrowing costs.

Headline PCE2.8%
Fed Target2.0%
10-Year Treasury4.28%

The timing compounds uncertainty. Jerome Powell’s term expires May 15, 2026, with Kevin Warsh viewed as more hawkish than his predecessor. Markets face a leadership transition alongside a potential policy reversal, introducing tail risks that equity option markets have yet to fully price.

CME FedWatch shows 92%+ probability the Fed holds rates at 3.50% to 3.75% at the March 18 meeting. The dot plot update matters more. The December dot plot projected one interest rate cut in 2026. If March’s projections show zero cuts—or hint at tightening—the repricing accelerates.

Cross-Asset Cascade

Bond markets moved first. The 10-year Treasury yield finished March 13 at 4.28%, with the 2-year at 3.73%, up 23 basis points over the past month according to Trading Economics. The benchmark yield is up nearly 13 basis points for the week, amid mounting concerns about an energy-driven inflationary spiral.

Equity markets reflected the rotation. David Russell called the GDP revision “a gut check going into this energy crunch, increasing the risk of stagflation”. Fourth-quarter GDP was revised down to just 0.7% growth, half the initial estimate, while inflation accelerated.

The dollar strengthened as safe-haven flows returned. The DXY exchange rate rose to 100.4976 on March 13, up 0.76% from the previous session and 3.70% over the past month per Trading Economics. A stronger dollar pressures emerging market debt and commodities priced in dollars, tightening global financial conditions even without Fed action.

AI Capex at Inflection Point

The macro shift arrives as AI infrastructure spending hits unprecedented scale. The five main hyperscalers had $241 billion in capital expenditures in 2024, with spending expected to rise to half a trillion dollars in 2026 according to Fidelity.

Context

Unlike the dot-com era, companies have funded AI-related capital expenditures almost entirely from earnings rather than debt. But higher rates still matter: they raise the discount rate applied to future cash flows, compress equity valuations, and make debt-funded M&A more expensive. For companies planning 2027-2028 data center expansions, the cost of capital just reset higher.

Investors are questioning whether AI-related capital spending will translate into profit gains worthy of current market valuations, with hyperscalers prompting questions about their ability to generate adequate returns on investment, according to Goldman Sachs equity strategist Peter Oppenheimer. The valuation tolerance for “growth at any price” narrows when 10-year Treasuries yield 4.28%—the risk-free alternative just became more attractive.

The S&P 500’s forward earnings yield is near parity with the 10-year U.S. Treasury—an equity risk premium of just 0.02%, among the lowest on record per Oppenheimer Asset Management. That configuration leaves little margin for error if rates rise further or earnings disappoint.

Geopolitical Wildcard

Iran conflict escalation injects a second-order inflation shock. Iran’s new Supreme Leader Mojtaba Khamenei pledged to keep the Strait of Hormuz closed, with West Texas Intermediate futures climbing 9.72% to settle at $95.73 a barrel per CNBC. Energy comprises roughly 8% of core PCE by weight, but second-order effects through transportation and production costs matter more.

Rate Cut Expectations Shift
Timeframe December 2025 Pricing Current Pricing
Q1 2026 Cut 35% probability 8% probability
Full-Year 2026 Cuts 2-3 cuts expected 0-1 cut expected
First Cut Timing March-June September (if any)

Investors are pricing in only one Fed rate cut in 2026, reinforced after PCE data showed annual inflation at 2.8%. If oil stays above $90 through Q2, that lone cut disappears from the pricing table entirely.

What to Watch

The March 18 FOMC meeting functions as a hinge point. The policy statement is scheduled for 2:00 PM ET with Chair Jerome Powell’s press conference at 2:30 PM. Three catalysts matter:

Key Signals
  • Dot plot shift: Does the median projection move from one cut to zero—or show any dots pricing hikes?
  • Powell language: Does he retire “transitory” rhetoric on energy shocks or acknowledge persistent services inflation?
  • Dissent pattern: Hawkish dissents from regional Fed presidents signal tightening bias gaining traction within the committee.

Growth stocks that rallied 40%+ in 2025 on rate-cut expectations face symmetric downside if those cuts evaporate. If price pressure persists and the Fed pivots away from its current stance, opening the door to rate hikes or tighter liquidity, financial conditions could tighten quickly, according to J.P. Morgan Global Research.

The February PCE report, due April 9, offers the next inflation checkpoint. Until then, markets navigate a regime where the Fed’s reaction function tilted from “dovish patience” to “hawkish optionality”—and the cost of capital reset higher for everyone building the AI future.
