Timiraos believes the first major test for Waller at the helm of the Federal Reserve is to determine the true nature of the AI boom: whether it resembles the 1996 productivity windfall (warranting a hold on rates) or the 1999 demand-driven overheating (requiring rate hikes). He leans toward embracing the AI-driven productivity narrative and holding off on rate increases for now, but faces pressures from tariffs and fiscal deficits, internal divisions over concerns that inflated AI expectations are fueling inflation, and the policy dilemma of abandoning forward guidance.
The primary challenge facing Waller upon assuming the chairmanship of the Federal Reserve is not whether to raise or lower interest rates, but a more fundamental judgment: what kind of boom is the current AI-driven surge? This assessment will determine the Fed’s policy trajectory and define Waller’s historical legacy.
On June 19, Nick Timiraos—often dubbed the 'new Fed whisperer'—noted that economists hold two starkly opposing interpretations regarding the AI investment boom:
First, productivity gains are about to materialize, allowing supply to catch up with demand, enabling the Fed to stand pat and let inflation subside naturally. Second, the benefits from productivity improvements remain distant, while demand-side pressures are already here; if the Fed waits for hard data confirmation, it will miss the optimal intervention window and ultimately be forced into sharper rate hikes.
The Fed held rates steady this week, but in its latest dot plot, nearly half of officials projected at least one more rate hike by year-end, while the rest held the opposite view—the depth of this internal split reflects the high degree of uncertainty surrounding this core question.
Waller’s own inclination was subtly evident during the press conference. He repeatedly emphasized, 'Strong, productivity-driven growth is not something we fear—it is something we embrace,' echoing Greenspan’s mindset from 1996.
However, the macroeconomic environment he faces—tariff pressures, widening fiscal deficits, and the waning benefits of globalization—is vastly different from the favorable tailwinds Greenspan enjoyed. Making the right judgment between these two historical narratives will be Waller’s first real test as Fed Chair.
Two 1990s: Greenspan’s Dual Legacy
Timiraos noted that over the past year, Waller has repeatedly invoked the 1990s as a historical reference—but that decade itself contains two distinctly different stories.
In 1996, Greenspan, facing rapid economic expansion, chose to stand pat. He judged that fast growth would not ignite inflation—and history proved him right. The expansion continued for years, earning him the moniker 'the Maestro.'
By 1999, Greenspan had changed his stance. With soaring equity markets and a persistently tightening labor market, he began a series of rate hikes, culminating in the dot-com bubble burst. It was also in that year that the Fed established its forward guidance framework—issuing early signals of impending rate hikes—a practice that endures to this day and one that Waller has explicitly stated he wishes to abolish.
The Trump administration openly admired the 1996 version of the Federal Reserve, and before taking office, Waller also publicly stated his desire to build a central bank that is 'confident enough to act less.' However, current economic conditions may now be handing him a different script.
Waller’s reasoning: Trust the narrative, not the data
Prior to assuming office, Waller expressed his position on Fox Business: he worried that the Fed was about to commit its 'sixth or seventh major mistake'—prematurely tightening monetary policy during a productivity boom that should have been allowed to run its course.
According to Timiraos, Waller’s core argument is that the productivity gains driven by AI will not immediately appear in official statistics and may take several years to materialize. If the Fed insists on waiting for data confirmation, it could misinterpret a benign boom as overheating and raise interest rates—an action that would precisely stifle the very growth momentum capable of containing inflation.
At its core, this logic advocates replacing lagging data with forward-looking narratives as the basis for policy decisions. Waller maintained this approach during his press conference: when asked whether AI is currently boosting demand or expanding supply, he merely noted that 'demand is easier to measure than supply,' deliberately avoiding a definitive stance while adhering to the communication principle of 'not signaling the next move in advance.'
Timiraos argues that even if Waller’s judgment ultimately proves correct, the analogy to the 1990s remains incomplete.
When Greenspan made his famous bet in 1996, multiple tailwinds supported his decision: cheap goods and labor from abroad continuously suppressed inflation, and the federal fiscal deficit was narrowing. These structural factors provided additional safety margins for the Fed’s 'wait-and-see' approach.
Waller faces a starkly different environment: tariff policies are pushing up import costs, the fiscal deficit is expanding rather than contracting, and the benefits of globalization have largely faded. This means that even if the AI-driven productivity gains eventually materialize as expected, the inflationary pressures Waller must endure during the waiting period will far exceed those faced by Greenspan at the time.
Counterargument: The Chicago Fed’s 'Expectations Discounting' Model
Timiraos notes that the most systematic challenge to Waller’s reasoning comes from Chicago Fed President Austan Goolsbee.
According to The Wall Street Journal, Goolsbee made a key distinction last month at a conference at Stanford University: whether a productivity boom allows central banks to stand pat depends on whether the boom is unexpected. A boom that everyone anticipates could have the opposite effect—people would front-load future wealth by significantly increasing spending before the productivity gains materialize, thereby overheating the economy.
"Ultimately, you end up having to raise rates sharply—much more than you would have needed to if you had acted earlier," Goolsbee said.
He argued that the current AI boom falls precisely into this 'widely anticipated' category. Surveys of economists, tech professionals, and the general public all indicate that markets broadly expect AI to deliver roughly one percentage point of annual productivity growth, with most of the benefits still ahead. According to his model, this expectation alone provides grounds for raising rates—not cutting them.
Goolsbee also cited real-world 'overheating signals': AI data center construction is driving up prices for land, electricity, and chips, while also increasing costs for electricians and equipment, thereby crowding out resources from other sectors. Apple’s announcement this week that it was raising prices due to rising costs served, in his view, as evidence that this mechanism is already at work.
Notably, Goolsbee’s framework faces challenges. At the same Stanford conference, Federal Reserve Governor Christopher Waller pointed out that the 'front-loading' mechanism only functions if people can borrow to spend ahead of their income. In reality, however, many households’ spending is tightly constrained by current income and cannot easily monetize future wealth.
"If they can’t front-load that spending, the entire mechanism breaks down," Waller said.
This counterargument lends theoretical support to Walsh’s stance of 'standing pat': if borrowing constraints are sufficiently widespread, the demand front-loading effect would be significantly muted, making it more likely that a productivity boom expands supply gently rather than triggering inflation.
The Ultimate Paradox: Abolishing Forward Guidance or Being Forced to Use It
Moreover, Timiraos argued that Walsh faces a deeper paradox in leading the Federal Reserve—one that stems precisely from the very change he most wants to implement.
He has clearly stated his desire to create a Federal Reserve that 'doesn’t reveal its hand in advance,' reducing forward guidance and keeping markets guessing. Yet the Fed’s current forward guidance framework was established in 1999—when Alan Greenspan began signaling rate hikes in advance to avoid catching markets off guard.
If the economic outlook proves as optimistic as described by the Trump administration, Walsh might never need to signal rate hikes in advance. But if the economy follows a different script, he will face a dilemma:
Either adhere to the forward guidance practice he hopes to abolish and inform markets in advance about planned rate hikes, or remain silent, leaving markets to speculate on the pace and magnitude of tightening—and bear the risk of heightened financial market volatility that may ensue.
The resolution to this paradox ultimately hinges on the answer to one question: Is it 1996, or is it 1999?
