October Market Insights: Warsh Fails The Test
Alexander Hamilton understood that debt is not necessarily a burden if it is matched by the means of extinguishment. The same principle should guide the American economy today. Debt can be managed when it finances productivity, expands the tax base and accelerates growth. It becomes dangerous when governments borrow merely to preserve stagnation.
That is the wager behind the economic strategy of U.S. President Donald Trump’s administration—run the economy hot enough to grow out of the debt. The objective is not simply short-term stimulus. It is to expand energy production, rebuild manufacturing, accelerate artificial-intelligence (AI) investment and bring industrial capacity back to the U.S.
This is a Hamiltonian strategy. It assumes that productive investment can enlarge the economy faster than liabilities accumulate. It treats energy, infrastructure, semiconductors, data centres, logistics and advanced manufacturing not as inflationary excesses but as the foundations of future supply.
Kevin Warsh, current Chair of the U.S. Federal Reserve (the ‘Fed’), appears to fail that test.
Warsh’s policy instincts remain anchored in the Fed’s old reaction function: watch headline inflation, monitor financial conditions, interpret market pricing as a signal of future inflation and tighten whenever economic activity appears too strong. That framework may have been defensible in a service economy dominated by incremental investment and relatively stable supply chains. It is badly suited to an economy undergoing a once-in-a-generation expansion of productive capacity.
The central danger is that Warsh would treat the AI investment boom as a conventional demand shock. Data centres require electricity, land, chips, networking equipment and construction. The spending is enormous. But the economic question is not whether the investment creates demand today—it does. The question is what that investment does to supply tomorrow.
AI capex can increase productivity, lower costs, expand output and create entirely new industries. It can reduce the labour required to produce goods and services. It can improve logistics, energy management, medical research, engineering and manufacturing. To treat every dollar spent on this infrastructure as evidence of overheating is to confuse the construction of productive capacity with the consumption of existing capacity.
That is a category error.
