Kevin Warsh’s First Fed Test Arrives Before the Swearing-In
<p>The yield on the 30-year U.S. Treasury bond closed Friday at <strong>5.11%</strong>, its highest level since 2007, just hours after the Federal Reserve Board kept Jerome Powell in place as chair pro tempore while Kevin Warsh waits to be sworn in. The number is a problem the new chair did not build, and a problem his own intellectual framework makes harder to solve.</p>
<p>Confirmed 54-45 last week in the closest Fed vote in modern history, the incoming chair inherits a long end of the curve pricing in exactly the scenario he has spent a decade warning about: inflation running hot for too long. The bond market did not wait for the swearing-in ceremony to issue its verdict.</p>
<h2>The 5.11% Greeting From the Long End</h2>
<p>Borrowing costs have climbed across the curve since February, but the move at the long end is the one that matters for the next chair&#8217;s opening weeks. The 30-year rose roughly 48 basis points in under three months, a velocity that resets mortgage math, corporate refinancing plans, and the Treasury&#8217;s own funding outlook in real time.</p>
<p>A snapshot of where the curve sat as Powell&#8217;s term wound down and Warsh&#8217;s began:</p>

<p>The auction tape tells the same story. The 30-year sold at a yield of 5.046% on Wednesday, the first auction to clear above 5% since 2007, per the <a href="https://home.treasury.gov/resource-center/data-chart-center/interest-rates/TextView?type=daily_treasury_yield_curve&#038;field_tdr_date_value=2026" target="_blank" rel="noopener">daily Treasury par yield curve published by the Department of the Treasury</a>. Buyers showed up; they just demanded a price the federal government has not had to pay in a generation.</p>
<p>For homebuyers, the spillover is immediate. The 30-year fixed mortgage tracks the long bond more closely than any single Fed move, which means the rate-cut narrative that animated rate-sensitive corners of the economy through 2025 has quietly inverted.</p>

<h2>Three Forces Pushing the Curve Higher</h2>
<p>The selloff in long Treasuries is not a single-cause event. Three forces are stacking on top of each other, and each one would matter on its own. Together they explain why the term premium has reawakened.</p>
<ul>
<li><strong>Energy supply shock.</strong> The closure of the Strait of Hormuz pushed Brent crude above $111 per barrel and lifted the U.S. headline consumer price index to 3.3% on an annual basis last month, the highest reading since May 2024. The <a href="https://www.dallasfed.org/research/economics/2026/0417" target="_blank" rel="noopener">Dallas Fed scenario analysis on Iran war inflation impact</a> estimates a 0.6 percentage-point bump to headline inflation this year even under a relatively benign one-quarter closure path.</li>
<li><strong>AI capital expenditure that refuses to slow.</strong> Wall Street now models 2026 hyperscaler capex between $800 billion and $900 billion. Microsoft alone guided to $190 billion this year, up 24%; Amazon committed to roughly $200 billion across the group. That spending is being financed in part with bond issuance, putting hyperscalers in direct competition with the Treasury for the same pool of long-duration capital.</li>
<li><strong>A federal deficit that keeps printing supply.</strong> Government borrowing remains near 6% of gross domestic product, and a single week this month saw the U.S. issue roughly $691 billion of Treasury securities across the maturity spectrum. Net supply at the long end is rising into a market that is repricing inflation risk in the same window.</li>
</ul>
<p>Each leg of that tripod feeds the others. Higher oil keeps near-term inflation expectations elevated; the AI build-out keeps demand resilient enough that the oil shock does not push the economy toward recession; the deficit guarantees that someone has to keep showing up at every auction. Investors are pricing the bill.</p>
<h2>When the Disinflation Thesis Becomes the Inflation Problem</h2>
<p>This is where the irony sharpens. The incoming chair built his case for the job partly on the argument that artificial intelligence would suppress prices over the medium term, giving the central bank room to cut without losing credibility.</p>
<h3>What Warsh Argued in November</h3>
<p>In a November 2025 essay, the future chair wrote that <strong>AI &#8220;will be a significant disinflationary force, increasing productivity and bolstering American competitiveness.&#8221;</strong> A one-percentage-point lift to annual productivity, he argued, would double living standards inside a single generation. The thesis matched the dovish posture the White House wanted from a Powell successor, and it became the centerpiece of his confirmation pitch.</p>
<p>That long-run case may yet prove correct. The Bridgewater desk and Goldman Sachs both model AI capex adding roughly 140 to 150 basis points to U.S. growth in 2026 and 2027, and productivity data takes years to verify, not quarters.</p>
<h3>What the Data Is Saying Right Now</h3>
<p>The near-term mechanics run the other way. The capex boom is so large that it is offsetting the growth-dampening effect a textbook oil shock would normally produce. U.S. demand is holding up. Investment is surging. And the only place the supposed disinflation is showing up is in stock-market multiples for the companies doing the spending, not in the price of gasoline or groceries.</p>
<p>Fed Vice Chair Philip Jefferson has flagged the asymmetry publicly. &#8220;AI&#8217;s effect on inflation is not solely downward pressure,&#8221; he said earlier this year, noting that scaling the technology could put upward pressure on specific price categories before any productivity dividend arrives. The five-year breakeven at 2.70%, the highest reading since 2023, is the bond market voting with Jefferson.</p>
<h2>An Awkward Handover With Two Dissents</h2>
<p>Powell&#8217;s term ended Friday. The chairman-designate has won Senate confirmation but is still waiting on a formal presidential commission and the liquidation of personal assets required by Federal Reserve ethics rules. So the Board of Governors took the unusual step of formally electing Powell to continue as chair pro tempore, per the <a href="https://www.federalreserve.gov/newsevents/pressreleases/other20260515a.htm" target="_blank" rel="noopener">May 15 Federal Reserve Board statement on the leadership transition</a>.</p>
<p>Two governors objected. Michelle Bowman, vice chair for supervision, and Stephen Miran filed a joint statement saying the arrangement should have carried an explicit time limit, capped at no more than a month and renewable by board vote or presidential action if the swearing-in had not occurred by then. Their <a href="https://www.federalreserve.gov/newsevents/pressreleases/bowman-miran-statement-20260515.htm" target="_blank" rel="noopener">joint dissent statement from Bowman and Miran</a> framed the lack of a deadline as a structural problem, not a personal one.</p>
<p>For an institution that prizes the appearance of orderly succession, having two sitting governors publicly disagree about how the transition is being managed is the kind of headline that bond traders notice. The market reads any governance friction as added uncertainty about how the policy path will be set in the chair&#8217;s first meeting.</p>
<h2>Why Yardeni Sees a Hawkish Pivot Coming</h2>
<p>Strategists who have watched the bond market drive Fed policy in past cycles are already mapping the script. Ed Yardeni, the veteran economist behind Yardeni Research, argues that the long end has effectively taken the rate-cut option off the table, and that the only credible response is to surprise the curve in the other direction.</p>
<blockquote>
<p>A more hawkish Warsh than the financial markets expect might stop bond yields from rising. By acting hawkishly, Warsh might have a chance of delivering what the White House wants: lower real-world borrowing costs.</p>
</blockquote>
<p>Yardeni now forecasts a 25 basis-point hike at the July Federal Open Market Committee meeting, with the June meeting used to telegraph the shift. CME FedWatch still puts a 97% probability on no change at the next meeting and prices fewer than three out of 100 odds of a cut at any meeting through year-end, which means the curve is open to a hawkish surprise but is nowhere near pricing one in.</p>
<p>The logic is mechanical. Cutting the short-term policy rate while five-year breakevens sit at 2.70% risks unmooring inflation expectations and pushing long yields higher still, the opposite of what the administration wants. Sending a tightening signal, by contrast, could compress the term premium and bring 30-year borrowing costs back down without doing much damage to the broader economy, which remains powered by the AI investment cycle. The bond vigilantes, as Yardeni calls them, are setting the new chair&#8217;s first meeting agenda whether he likes it or not.</p>
<h2>Reading the Breakevens Before July</h2>
<p>The clearest signal to watch in the next eight weeks is the spread between nominal Treasuries and Treasury Inflation-Protected Securities. Five-year breakevens climbing further would tell the central bank that the oil shock is bleeding into expectations; a roll-over would buy the new chair room to wait. Either way, the longer-dated 5-to-10-year measure at 2.29% suggests investors are more worried about the federal borrowing trajectory and the capex cycle than about a 1970s-style inflation regime.</p>
<p>The price of a 30-year mortgage, the cost of corporate refinancing, and the Treasury&#8217;s own debt-service line all sit downstream of that same long bond. Each tick higher tightens financial conditions in places monetary policy usually reaches only with a lag.</p>
<p>If the July meeting brings the hawkish surprise Yardeni outlines, the curve flattens and the new chair gets credit for restoring credibility before his first full quarter is done. If the meeting brings a hold and a dovish statement, the long bond is likely to keep telling the central bank what it thinks about the inflation outlook, in basis points, every day until something gives.</p>
