The passing of former Federal Reserve Chairman Alan Greenspan at the age of 100 marks more than just the end of an era; it signals a ideological resurrection within the world’s most powerful central bank. As newly sworn-in Chairman Kevin Warsh takes the helm, he is explicitly invoking the 'Greenspan legacy' to dismantle the rigid, data-dependent frameworks that have defined the Fed for the past two decades. Warsh’s agenda suggests a return to the 'art' of central banking, prioritizing human judgment over the static econometric models that critics argue have left the Fed perpetually behind the curve.
In his inaugural move, Warsh established five specialized task forces to conduct a top-to-bottom overhaul of the Fed’s operational DNA, focusing on everything from communication mechanisms to the utilization of artificial intelligence data. This restructuring aims to move away from the 'forward guidance' era, characterized by dot plots and explicit promises, which Warsh believes has forced markets to obsess over Fed predictions rather than real economic signals. By seeking a return to 'constructive ambiguity,' the new Chairman hopes to restore the flexibility that allowed Greenspan to navigate the 1990s productivity boom without triggering premature rate hikes.
The parallels between the current AI-driven surge and the 1990s internet revolution are central to this policy shift. Much like Greenspan recognized that surging productivity was keeping inflation in check despite low unemployment, Warsh is betting that AI-led gains in Total Factor Productivity (TFP) will allow for a more accommodative stance than traditional models would suggest. However, this transition is not without significant risk, as critics recall that Greenspan’s era of discretionary 'light-touch' regulation eventually paved the way for the 2008 financial crisis.
Ultimately, Warsh’s Fed appears ready to trade the transparency of the Bernanke-Yellen-Powell years for a more intuitive, growth-oriented posture. By inviting outside experts and rethinking the '充足储备' (ample reserves) system, the central bank is attempting to regain its status as an institution that leads the market rather than one that merely reacts to it. Whether this return to the 'Greenspan Masterclass' can successfully tame the modern economic cycle—or if it will lead to another era of asset bubbles—remains the defining question for the global economy in 2026.
