Warsh Woke Up The Bond Vigilantes

Jul 31, 2026 · 38m · 4 min read · Alfonso Peccatillo, Brent Donnelly

Alfonso Peccatillo argues Fed Chair Warsh is running a "Maradona theory of interest rates" — refusing to hike or offer any framework and effectively handing tightening and easing to the bond market, which is why long-end US yields (5.55% 10y10y forward) sit far above Japan's comparable 4% despite inflation swaps staying low. Both he and Brent Donnelly flag fading fiscal impulse (OBBB tax refunds gone by June, only a $90bn reconciliation bill floated, Senate pushback), decelerating AI capex, and ADP weekly job creation down to a 60k/month run-rate as reasons growth could disappoint into 2027, with no Fed cushion this time if stocks wobble the way they did into the 2018 low. Peccatillo's stated highest-conviction trade for the next three to four months is long euro and long bonds; Donnelly is sympathetic to the logic but wants a catalyst (the NFP print two Fridays out) before committing to bonds, and is currently short CHF/JPY as a yen-strength expression tied to GPIF's expected repatriation into domestic bonds.

Core argument. Alfonso Peccatillo says Fed Chair Warsh's press conference gave the market no intellectual framework — no inflation weighting scheme, no forward guidance, nothing like the Powell-era core PCE/services-ex-housing breakdowns. He calls this the "Maradona theory of interest rates": the Fed won't touch the ball (won't move fed funds) and is instead dribbling past the market, effectively letting bond yields do the tightening and easing for them. Both hosts read the bond selloff after the meeting as the market's response to that vacuum.

The mechanism. Peccatillo's puzzle: if the market doubts Fed credibility, why are inflation swaps still low? His answer — swap positioning carries negative-carry risk every CPI print, so real-money players are reluctant to bet on an inflation runaway, and his own models show no near-term inflation acceleration (wage pressure is low). Instead the bond vigilantes are pricing a higher real neutral rate to slow growth. He points to Japan as the template: long-and-forward Japanese rates have risen to roughly 4% (high by Japanese standards) purely via real yields, not breakevens, because the market is enforcing a non-inflationary growth path. US long-and-forward rates, by his morning check, sit at 5.55% (5y5y10y-type forward) — meaning the US bond market is demanding a materially higher real neutral rate than the Fed has been willing to state itself.

What has to be true. For this to matter, growth has to actually be softening. Peccatillo lays out the fiscal picture: the One Big Beautiful Bill's tax-refund impulse is exhausted by June, turning into fiscal tightening; a proposed pre-midterm reconciliation bill is only $90 billion and already facing Senate Republican pushback, so no fiscal replacement is likely before the midterms. AI capex growth is decelerating (the second derivative is falling), and ADP weekly job-creation data (through July 11) has slowed to roughly 15k/week, annualizing to about 60k/month — a breakeven pace before the fiscal drag even bites. His conclusion: US growth should be below potential, not above consensus.

Donnelly raises the circularity risk directly: yields rising far enough eventually chokes growth, which becomes bullish bonds — he's been early to this call before and is surprised by how far real yields have still pushed. Both agree the self-correcting mechanism is real but uncertain in timing, and that absent a full fiscal crisis, multi-year outright short-bond bets rarely pay for more than a week or two.

On equities, Peccatillo asks whether a growth shock this cycle gets a monetary offset at all — under the Maradona framework, the Fed "says nothing" the way it did last year when Powell pivoted preemptively; instead the market gets only whatever bond rally naturally follows a slowdown, without direct policy stimulus. Donnelly draws the 2018–2019 parallel: that selloff was stopped by forward guidance alone, before any actual cut — if that channel is closed, downside skew in equities is larger. He also flags idiosyncratic cracks already visible: Korean stocks and Micron (which traded to $1,255 on earnings and is now near $740) have had large drawdowns already. Drawing the parallel to gold and silver — where realized vol has collapsed into a range after the blowoff top near $117 silver — both say their base case is that momentum names like Micron consolidate/range-trade for a couple of months rather than making fresh highs, and Donnelly cites Vanda data showing retail, previously the reliable dip-buyer, has largely stopped buying after losses in gold, silver, quantum computing and space names — a bearish-at-the-margin signal with no obvious second wave of buyers.

The trade. Peccatillo's explicit call: long euro and long bonds offer the best Sharpe ratio over the next three to four months, a trade he says almost nobody currently holds (consensus is long stocks/AI/EM carry, short bonds, steepeners). Donnelly agrees directionally on FX — dollar/yen and dollar/swiss look crowded after hedging flows into a hike that only had 30–35% odds — but says as a trader he has no catalyst yet for bonds and would wait for the next NFP (two Fridays out) or repeated attempts around data (payrolls, then CPI) rather than picking levels without a trigger; unanchored entries without a catalyst are, in his view, low or negative EV. On yen, Donnelly is short CHF/JPY (unmoved so far) on the view that GPIF is slowly rotating toward domestic bonds — reinforced by GPIF hiring three domestic bond managers and public comments from Japanese officials pushing for more domestic allocation — plus recurring MOF/BOJ intervention risk. He notes EUR/JPY has recently traded like a pure dollar trade rather than an idiosyncratic yen story, but expects the yen-specific trade to emerge over the next two to three months.

Elsewhere. On South Africa: SARB held rates despite inflation at 5% versus a lowered 3% target, and the long end of the curve and the rand (down 2.5% in a day) sold off sharply; Peccatillo remains constructive medium-term on the country's fiscal and monetary credibility. He flags a live risk-management problem: front-end EM and UK receiver trades (South Africa, Poland, gilts) have repeatedly blown up in July on oil-price spikes tied to geopolitical headlines, meaning ostensibly uncorrelated trades share a hidden oil factor — the fix discussed is either an oil hedge or relative value (receive against something disliked) rather than trying to hedge every factor, since over-hedging a macro book just erases the position. Bearish names: Poland (presidential vetoes of the budget, a constitutional debt limit, a structurally dovish central bank) and Indonesia (central bank governor's abrupt resignation, a nepotistic appointment by President Prabowo, weak rupee and asset prices).

Both say they trade with a fundamental thesis first and use price action/technicals only to size entries or add leverage — not as a standalone signal — with one exception: extreme statistical dislocations (Donnelly cites roughly 3–3.5 standard deviations from a 100-day average, especially when driven by forced liquidation) can justify a trade with a tight one- or two-day-range stop even without full conviction. On hedging concentrated macro factor risk, Peccatillo's rule: buy the hedge when it's cheap rather than talk yourself out of it, and prefer selling put spreads (asymmetric, positive-skew, roughly 3:1 payout) over naked puts, which he calls something to "leave to very brave people."

Takeaways / the view

The stated highest-conviction trade is long euro and long bonds, which Peccatillo argues offers the best Sharpe over the next three to four months precisely because almost no one holds it against a consensus long-stocks/AI/EM-carry, short-bonds-and-steepener book. Donnelly is sympathetic to the macro logic — crowded dollar/yen and dollar/swiss positioning, a fading fiscal impulse, decelerating AI capex, and ADP data running near breakeven — but wants a catalyst before trading bonds, watching the next NFP two Fridays out. Both view Micron, Korean equities and the broader momentum complex as likely to range-trade rather than retest highs, drawing the parallel to gold and silver's post-blowout stall, with retail buying (per Vanda) notably absent this time. Separately, Donnelly is short CHF/JPY on a GPIF-repatriation thesis that hasn't moved yet, and both flag oil-driven correlation risk across EM and UK rate-receiver trades (South Africa, Poland, gilts) as the factor to hedge or trade around rather than eliminate outright.
