The Real Greenspan Lesson Warsh Must Learn on Inflation

Inflation sits at 2.9%—still above the Fed's 2% target. Yet as Kevin Warsh prepares for his Fed Chair confirmation, the question isn't whether he can fight inflation, but whether he understands what Alan Greenspan really taught us about monetary policy.

Beyond the Inflation Fighter Myth

Greenspan's 18-year tenure is often remembered for taming inflation, but that misses the point entirely. His real genius wasn't in crushing price pressures—it was in reading the economic moment.

When Greenspan took over in 1987, his predecessor Paul Volcker had already done the heavy lifting, pushing rates to 20% to break the back of 1970s inflation. Greenspan inherited a different challenge: maintaining stability while allowing growth. He didn't just follow a playbook—he wrote one based on economic nuance.

The "Greenspan Put" wasn't about inflation targeting. It was about recognizing that economic conditions change, and monetary policy must adapt accordingly.

Warsh's Inflation Tunnel Vision

Warsh has built his reputation as an inflation hawk, warning against the dangers of loose monetary policy. That sounds prudent until you consider today's economic landscape.

Current inflation isn't driven by excess demand or wage spirals—the traditional culprits Greenspan faced. Instead, we're dealing with structural shifts: supply chain reshoring, deglobalization, and labor market transformation. These forces don't respond to interest rate adjustments the same way.

Raising rates aggressively might cool headline inflation numbers, but at what cost? The housing market is already showing stress, and corporate borrowing costs are crimping investment in productivity-enhancing technology.

The Numbers Behind the Numbers

That 2.9% inflation figure masks significant variation. Housing costs continue rising at 6% annually, while goods prices are actually falling in many categories. Services inflation remains sticky, but manufacturing prices are deflating.

Greenspan understood these cross-currents. He didn't just look at headline numbers—he dissected regional variations, sector-specific trends, and forward-looking indicators. His famous data obsession wasn't academic; it informed policy precision.

Warsh's public statements suggest a more binary approach: inflation above target equals tighter policy. But what if the inflation we're seeing requires surgical precision rather than a sledgehammer?

The Global Stakes

American monetary policy doesn't exist in a vacuum. Aggressive rate hikes would strengthen the dollar, potentially destabilizing emerging markets and disrupting global trade flows. European and Asian central banks would face impossible choices between defending their currencies and supporting domestic growth.

For American consumers, the trade-offs are stark. Higher rates might cool inflation, but they'll also increase mortgage payments, credit card costs, and business investment. The cure could prove worse than the disease.
