Think the Fed can always tame inflation if it just hikes a little harder? We sat down with economist Eric Leeper to unpack why that story falls apart once you account for Congress’s power over taxes, spending, and debt. Eric explains operational independence in plain terms, traces how the modern central bank mandate evolved, and shows why economic outcomes depend on both monetary and fiscal choices—especially when higher rates swell interest costs and the bill gets rolled into more borrowing.

We walk through the fiscal foundations of inflation: $40 trillion in government liabilities backed by the expectation of future primary surpluses. When those expectations wobble, the price level does the adjustment. That lens reframes the 1970s and Volcker era, highlighting the fiscal steps that helped disinflation succeed. Fast forward to today’s 100 percent debt-to-GDP world and the signals are harder to ignore—tailing Treasury auctions, a tilt to shorter maturities, and foreign buyers stepping back. Eric connects those dots to fiscal dominance, where rate hikes can perversely fuel inflation by making bondholders feel richer, forcing the Fed into a damaging loop of ever-tighter policy and ever-rising debt service.

So what actually works? Eric outlines a pragmatic Plan B for central banks when Congress won’t deliver credibility: prioritize smoother, more predictable inflation paths, reduce policy whiplash, and communicate the fiscal conditions required to reclaim durable price stability. Along the way, we revisit the “Hamilton norm,” examine the UK’s 2022 market shock as a cautionary tale, and challenge the idea that inflation control lives only at the Fed.
