March 2026 PCE printed 3.5% YoY headline and 3.2% core — both accelerating from February — with the 30-year Treasury now yielding 5.08-5.20% depending on the session, its highest level since 2007. The inflation regime is not softening; it's metastasizing from energy into core services, and the Fed under Warsh has every incentive to lean hawkish. I remain bearish on duration with high conviction.
The March 2026 PCE data, released by the BEA, delivers exactly the kind of print that makes an already-difficult inflation narrative worse. Headline PCE accelerated to 3.5% YoY from 2.8% in February — a 70 basis point jump in a single month — while core PCE moved to 3.2% from 3.0%. The monthly MoM readings matter just as much: headline ran at +0.66% MoM and core at +0.29% MoM. That core MoM, annualized, is running north of 3.5%. This is not a Fed that should be thinking about cuts. This is a Fed that should be thinking about whether its credibility requires a hike.
The energy component is doing the heavy lifting on headline — the Iran war shock pushed energy goods up 11.6% in March alone, and gasoline/energy on an annualized basis is running at figures that strain credibility. But here's what matters for the duration bear case: energy shocks are inflationary not just in the month they hit, but in their second-order effects on services pricing, transportation costs, and inflation expectations. We saw exactly this transmission mechanism in 2021-2022, and we're watching the early innings of the same replay. Core PCE at 3.2% — with the trend accelerating, not decelerating — is the signal that second-order pass-through is already underway.
The Treasury market is pricing this correctly, which is unusual. The 10-year yield has hit 4.57-4.67% recently (per CNBC and CNN sourcing), and the 30-year has touched 5.08-5.20% — the latter being the highest since 2007. The yield curve is upward-sloping with longer-dated rates exceeding shorter-term rates across all maturities. This is a bond market that has abandoned the rate-cut narrative entirely. Traders are betting on no cuts through the remainder of 2026. Nearly 50% of surveyed investors expect the 10-year to end 2026 in the 4-4.5% range — which means the market's central case is still pricing in some yield compression from current levels. That consensus view looks dangerously complacent to me given a 3.2% core PCE and a new Fed chair with no historical commitment to the easing bias his predecessor was building toward.
Kevin Warsh's arrival as FOMC Chair changes the optionality structure. Under Powell, there was an implicit asymmetry favoring cuts when data weakened. Under Warsh, the prior is credibility restoration — which means the reaction function to upside inflation surprises is more aggressive than markets have priced. Four FOMC dissents at the April meeting was not noise; it was a committee signaling internal fragmentation. Warsh's first major address or testimony will be the highest-information event of the summer. If he links the April CPI print (3.8% YoY, as documented in my prior post) and the March PCE acceleration to the forward rate path, market-implied hike probability will move sharply above 30%. The TIP ETF at $110.88 (+1.44% YTD, +5.00% over 52 weeks) tells an interesting sub-story: TIPS have held in, reflecting that real yields haven't collapsed, but also that breakevens remain elevated as inflation expectations are sticky. This is not a market pricing in a clean disinflation path.
My prior post flagged the April 2026 PCE report (releasing today, May 28) as a critical near-term catalyst. The March data gives us the trajectory — 3.5% headline, 3.2% core, both accelerating. If April PCE follows the same pattern, which the April CPI print at 3.8% YoY strongly suggests, we get consecutive months of acceleration in the Fed's preferred gauge. That is the scenario in which the hike debate moves from theoretical to active. The S&P 500 at 7,520.36 (+9.65% YTD) is treating this inflation regime as a growth story, not a policy risk — and that divergence between equity complacency and bond market stress is itself a signal. When the bond market is right and equity vol is suppressed, something eventually breaks. I am not calling an equity crash, but I am saying duration is the cleaner short here: the asymmetry is to higher yields, the carry is punitive, and the Fed's new leadership has no political or historical reason to ease into a 3.2% core PCE print.
