Unlike most presidents, who try to manage the economy, President Trump tries to manage the market. He watches the tape like a floor trader, adjusting policy in response.
To his credit, Trump may understand the psychology of financial markets better than any modern predecessor.
He behaves as though rising asset prices are not just a consequence of successful policy, but a real-time scorecard of his presidency. He has shown, repeatedly, that when the market pushes back hard enough, he bends. And that has served him well, so far. This instinct isn’t new.
During the 2016 campaign, Paul Krugman repeatedly warned in op-eds that markets would tank if Trump won. They didn’t.
Instead, Trump turbocharged equities with tax cuts and deregulation. His trade war with China never broke the rally.
Then Covid hit, and stocks cratered, but that was a black-swan event, not a verdict on Trump.
A Different Second Term
In his second term, Trump is more combative, less predictable, and far more reactive to real-time market feedback.
Consider these three episodes:
First, tariffs. The back-and-forth on tariffs in 2025 produced extreme market volatility. But Trump kept adjusting course, and many investors concluded he could be talked out of his harder positions if the selling got bad enough.
Investors are convinced that Trump’s stated tariff position and his actual tariff position are two different things, and they trade around that assumption.
A similar pattern appears with the Iran conflict. Trump’s willingness to step back from more aggressive rhetoric suggests that, even in foreign policy, he is sensitive to the market consequences of his decisions.
Second, the war on Powell. Trump relentlessly pressured then-Chair Powell to cut rates and repeatedly threatened to fire him. That tested the tolerance even of a market broadly sympathetic to Trump and intoxicated by the promise of AI.
Even investors who crave low rates fear that a Fed perceived to be under political control is a much bigger problem than a Fed moving too slowly. The market pushed back sharply, and Trump backed off.
Third, the Warsh appointment. His Senate confirmation, 54-45, was the most divisive Fed chair vote in modern history.
The vote raises an uncomfortable question: is monetary policy still insulated from politics? Markets, however, mostly shrugged and moved on.
That was odd. Trump’s open demand for a dovish successor and his public calls for rate cuts from whoever got the job suggested a chair whose mandate was implicitly political rather than purely data-driven.
I was surprised that the market didn’t react with anywhere near the same sharp pushback it had when Powell was the issue.
Warsh, Opacity, and Lack of Consensus
Warsh stripped forward guidance out of the Fed’s communications almost entirely, shortening FOMC statements.
He could have taken the Greenspan approach—crafting ambiguous guidance that gave markets a signal without committing the Fed to a specific path. Warsh chose opacity instead.
I don’t think Warsh commands the same authority within the Fed that Powell, Bernanke, and Greenspan did.
At the July 29, 2026 meeting, the FOMC held rates steady, but three regional presidents dissented in favor of a hike. Inflation hawkishness within the FOMC is broader than just an isolated voice.
I may be misjudging Warsh; he could simply be more comfortable with open disagreement than his predecessors were.
Or, perhaps he’s allowing rising Treasury yields to communicate the Fed’s inflation concerns rather than emphasizing them himself.
If so, he preserves the Fed’s independence from the White House while allowing the market to do some of the work. That would leave Trump confronting a signal he has paid close attention to: the bond market.
When Stocks and Bonds Disagree
The stock market largely looked past the Warsh appointment. The bond market, however, has been more skeptical.
When the two diverge, it often pays to heed the bond market. That market is dominated by institutional investors making long-duration bets on inflation and government credibility.
Since the July decision, the bond market’s skepticism has shown up directly in Treasury prices. The 10-year Treasury yield is gradually inching beyond 4.75%, and the 30-year yield has reached its highest level since 2007.
So far, stocks seem to be shrugging off the bond sell-off.
The market is betting that AI-driven productivity gains will be deflationary, allowing faster growth without permanently higher inflation. The heavy borrowing to finance AI infrastructure suggests a vote of confidence in that future.
If that holds, a 4.75% 10-year yield is not a warning sign; it’s the price of a healthier economy.
When growth prospects improve, investors demand higher returns from other assets, forcing bonds to offer more attractive yields to compete. In that case, rising yields may reflect optimism, not fear.
The problem is that rising yields can also reflect something far less benign: concerns about inflation or doubts about the Fed’s ability to maintain price stability.
The deeper worry is the Fed’s inflation credibility.
Inflation expectations usually do not change overnight. They drift. The inflation-protected Treasury market does not suggest that investors expect 3% inflation to persist. But after several years above target, investors may begin questioning whether the 2% inflation regime remains firmly anchored.
That distinction matters. Bond investors do not need to believe inflation will become permanently higher to demand higher yields. They only need to believe that the risk of persistent inflation, or a Fed perceived as less willing or less able to fight it, has increased.
The Limits of Market Management
The pattern across Trump’s second term is consistent: he tests the market’s tolerance, and when the market pushes back hard enough, he adjusts. But Fed credibility is different from tariffs or political messaging.
If the AI-driven optimism that has supported equities begins to fade, concerns about Fed independence could move from the background to the foreground.
Trump can reverse a tariff tweet in minutes to calm an equity selloff. But if the bond market loses confidence in a Fed perceived as unanchored, no amount of presidential persuasion can bring 10-year yields back down.
