CNBC The Exchange
2026-09-17 · Hosted by Kelly Evans · CNBC
Executive Summary
CNBC's The Exchange broadcast a two-hour special from Washington DC ahead of the Fed's rate decision, with hosts Kelly Evans and Brian Sullivan running a rotating panel of economists and policymakers. Going into the 2pm announcement, markets priced a 91% chance of a quarter-point hike, with a 78% probability of a follow-up hike in December and a third possible by March 2027. Panelists Stephen Whiting (Citi), former Philadelphia Fed president Patrick Harker, and Schwab's Liz Ann Sonders debated whether the Fed needs to act given inflation running near 3% on its preferred PCE measure — above target for five years — even though rate hikes can't directly fix energy-driven supply shocks.
Key Stories & Changes
1. Fed Decision Setup: 91% Priced-In Hike, Question Is Guidance
Markets priced 91% probability of a September hike, 78% for a follow-up in December, and a possible third hike by March 2027
Steve Liesman: reasons to hike include PCE inflation above 3% (Fed's preferred gauge), five years above the 2% target, and signs inflation is broadening beyond energy; reasons to hold include the argument that rate hikes "don't produce oil" and can't fix supply-driven price shocks
Coined framing: "one and done" vs. "one and mum" (a hike without clear guidance on next steps)
10-year Treasury yield hovering just under 5%, having hit a nearly two-decade high of 5.04% the prior day (highest since 2007)
2. Panel Debate: Credibility vs. Economic Necessity
Patrick Harker (former Philadelphia Fed president): argues the Fed must hike to preserve "credibility premia" with markets; a hold would trigger a market "revolt"
Stephen Whiting (Citi): notes every Fed tightening cycle in history has been a yield-curve-flattening cycle; not hiking after months of hawkish rhetoric risks destabilizing the currency and long-end bond market
Liz Ann Sonders (Schwab): argues current inflation isn't just a legacy of 2022 mistakes — there is genuine demand-side inflation from AI CapEx (capital expenditure, i.e. investment spending) and labor market tightness, citing NFIB data showing "quality of labor" as small businesses' top concern
Sonders highlighted a structural shift: bond yields and stock prices have reverted to an inverse correlation (last seen pre-"Great Moderation"), meaning stocks and bonds may increasingly move together rather than offsetting each other for diversification
3. Carlyle's Jason Thomas vs. Faulkender on Whether Hikes Matter
Jason Thomas (Carlyle Group, head of global research): argues "these aren't normal times" — cumulative post-COVID inflation has created lasting pricing power; companies that never raised prices in 20 years are now raising them 20-30% without demand pullback, suggesting excess demand relative to productive capacity
Core PCE trends this year improved from 4.4% (April) to roughly 2.9% three-month annualized (August), a disinflationary trend Thomas partly attributes to normalizing categories like auto insurance (up 45% from 2022-2024, down 6% this year)
Michael Faulkender (former Deputy Treasury Secretary, now University of Maryland professor): argues core CPI excluding direct and indirect energy items was near 2.1% year-over-year, suggesting monetary policy is already near where it needs to be
Faulkender said the Fed is effectively being "bullied" — first by the bond market, and now by fellow FOMC members who "have a different view" on monetary policy's role in curtailing inflation — into hiking despite Warsh's own skepticism
4. Congressman Gottheimer on AI Regulation and Energy Costs
Rep. Josh Gottheimer (D-NJ, co-chair of House Democratic Commission on AI): advocates mandatory government review/time-limited review for new AI models before release
Says "you can't put this in a box and chuck it in the Hudson" — rejects both no-regulation and shutdown extremes
Cited local frustration: gas near $4.50/gallon in New Jersey, diesel at $6.25, and farmers "flipping out" over fuel costs
On data centers: supports permitting reform to add electricity supply but says communities should have the right to reject local data centers, and companies shouldn't receive tax breaks while raising electric/water bills
5. Michael Faulkender on the Treasury Buyback Program and Balance Sheet
Said the Treasury's enhanced bond buyback program (~$6 billion vs. normal $2 billion) is not large enough to have caused the recent spike in yields
Argued the Fed's balance sheet reduction (quantitative tightening) is a more appropriate tool than rate hikes for signaling inflation-fighting credibility, but doesn't expect Warsh to act on it until an internal task force reports back
Noted a weak 20-year Treasury auction the prior day, adding to yield pressure
Trends Identified
1. Fed Credibility Concerns Increasingly Driving Policy, Not Just Data
Multiple guests (Harker, Whiting, Faulkender) framed the Fed's likely hike as driven substantially by a need to maintain market credibility rather than by a belief that 25 basis points will meaningfully affect inflation. This suggests markets themselves are becoming a policy input, with the bond market effectively "voting" on the Fed's next move via yield pricing.
2. Bond-Stock Correlation Regime Shift Raises Diversification Risk
Liz Ann Sonders' point about reverting to an inverse bond-yield/stock-price correlation — last seen for roughly 30 years before the "Great Moderation" — signals a structural change where inflation, not growth, is now the dominant driver of yields. This could reduce the diversification benefit of traditional 60/40 portfolios going forward.
3. Demand-Side AI Inflation Complicates the "Just a Supply Shock" Narrative
While oil and diesel price spikes dominate headlines, several guests (Sonders, Thomas) pointed to AI-related CapEx and labor tightness as a genuine demand-side inflation driver that rate hikes could theoretically address — unlike pure energy supply shocks, which are outside the Fed's toolkit.
4. Political and Consumer Pressure Mounting on Multiple Fronts
Congressman Gottheimer's on-the-ground reporting of $4.50 gas and $6.25 diesel in New Jersey, combined with Trump's public criticism of the Fed, illustrates how energy costs are becoming both an economic and political flashpoint ahead of the midterms. ---
Sentiment Analysis
Overall Market Sentiment: Tense Anticipation, Hawkish Lean
Guests broadly expected a hike and largely agreed it was justified on credibility grounds, even while disagreeing sharply on whether it would actually address the underlying causes of inflation.
Risk Factors Highlighted
Long-end bond market destabilization: Multiple guests warned a non-hike could trigger a disorderly spike in long-term yields and currency instability.
Energy supply shock persistence: Diesel and gasoline prices remain elevated with no clear resolution timeline, and rate hikes cannot directly address the root cause.
AI CapEx-driven demand inflation: Sonders and Thomas flagged this as a less-discussed but potentially more persistent inflation source than energy alone.
Bond-equity correlation regime shift: A reversion to inverse stock-bond correlation could reduce portfolio diversification benefits going forward.
Consumer affordability strain: Rising gas, diesel, food, and insurance costs are disproportionately affecting lower- and middle-income households, a point raised repeatedly by Sullivan.
AI regulatory uncertainty: Gottheimer flagged national security risk (citing summer cyberattacks on water utilities in 10 states) if AI models aren't reviewed before release, alongside competitiveness risk if regulation goes too far.
Fed communication/credibility risk: Faulkender argued Warsh has "let the market back him into a corner" by not pushing back earlier on hawkish expectations, raising the risk of a credibility misstep regardless of the decision.
Weak Treasury auction demand: A poorly received 20-year bond auction the previous day added to concerns about federal borrowing costs and market absorption capacity.
