Macro Lit Review 1: Highlights from Mid-2022 with George Selgin

Episode Summary

Executive Summary: David Beckworth and George Selgin review recent macro and monetary-policy debates: CBDCs vs stablecoins, whether Fed balance-sheet losses matter, the dollar’s reserve-currency dominance, inflation accountability at the Fed, and the design of reserve operating systems. Selgin argues CBDCs are unnecessary and potentially distortionary, while Beckworth and Selgin agree the Fed is still behind on inflation but has improved in acknowledging mistakes.

Main Topics: CBDCs, stablecoins, and level playing fields (Priority: 5/5): Selgin criticizes Lael Brainard’s defense of a Fed-issued CBDC, arguing the Fed cannot be a neutral competitor because of monopoly privileges, regulatory power, and the ability to cross-subsidize products like FedNow. He says stablecoins can serve payment functions without the same distortions. Fed balance-sheet losses and taxpayer costs (Priority: 5/5): Beckworth discusses Bill Nelson’s claim that unrealized SOMA losses are economically real because they imply lower future remittances to Treasury. Selgin agrees the issue hinges on future interest-rate paths and whether the Fed eventually earns enough seigniorage to offset present losses. Inflation, Yellen, and the Fed falling behind the curve (Priority: 5/5): Selgin says the COVID fiscal response was excessive, the Fed tightened too late, and inflation was driven by both demand and supply shocks, including the Ukraine war. Beckworth adds that a better focus on expected inflation and nominal GDP would have signaled tightening sooner. Dollar reserve-currency dominance (Priority: 5/5): Beckworth highlights Mark Copelovitch’s defense of the dollar’s global role and argues network effects, swap-line backstops, Chinese capital-account constraints, and trust in U.S. institutions make the dollar hard to displace. Selgin ties this to Menger-style network economics. Central bank operating regimes: floor, corridor, and ceiling systems (Priority: 4/5): Selgin discusses a theoretical paper arguing corridor systems are optimal in booms and floor systems in busts, but notes that a corridor system effectively turns into a floor system at the zero lower bound. He is skeptical of moves toward a partial or quasi-ceiling system. Fed transparency, humility, and communication errors (Priority: 4/5): Both speakers praise the Fed’s greater willingness to admit mistakes compared with the 1970s, but Selgin criticizes forward guidance that promised no rate hikes until 2023–24, arguing the Fed should avoid making commitments it may need to reverse.

Key Arguments: CBDCs are not a necessary or superior public alternative to stablecoins for payments; the Fed’s market power means it cannot compete on equal terms. Unrealized losses on the Fed’s assets matter because they reflect higher future interest expenses and lower remittances to Treasury; whether they are ultimately offset depends on future monetary profits. Inflation should be judged through expected future inflation and nominal spending, not naive one-for-one applications of the Taylor principle to current inflation. The dollar’s reserve-currency status is reinforced by network effects, scale, and crisis backstops, making displacement by the euro, yuan, or other systems difficult. China faces major barriers to reserve-currency status: capital controls, the need to run deficits, and limited investor trust. Reserve regimes should be understood as state-contingent: corridor systems work when reserves are scarce, but floor systems become necessary at the lower bound. The Fed’s improved admission of mistakes is positive, but communication should avoid hard promises that create credibility traps. Nominal GDP measures and forecasts can provide a cleaner signal of overheating than headline inflation alone, because they separate demand from supply shocks.

Data Points: Macro Musings appearance count: 11th time - George Selgin is introduced as the most frequent guest on the podcast. Estimated global dollar-denominated debt/liquidity: Almost $78 trillion - Beckworth cites BIS global liquidity indicator data for dollar-denominated debt/assets. Estimated euro-denominated global debt/liquidity: $33 trillion - Used to illustrate the dollar’s scale advantage. Estimated yen-denominated global debt/liquidity: About $20 trillion - Used to show other currency systems are much smaller than the dollar system. Fed balance-sheet paper loss discussed: Almost $500 billion - Selgin/Beckworth reference the magnitude of first-quarter losses from rising rates. Nominal GDP growth cited: 12% annualized - Beckworth says the latest annual NGDP figure showed spending growth far above trend. Pre-COVID NGDP trend growth: 4% to 5% per year - Beckworth references this as the rough sustainable trend. Inflation break-even discussed: Around 2.6% for 10 years - Selgin notes market-based long-run inflation expectations remain above target. Implied tightening magnitude by some commentators: 7 to 8 percentage points - Selgin criticizes naive Taylor-rule-style calls for very large hikes. Beckworth’s suggested modest tightening amount: 20 to 25 basis points - He argues the Fed should have begun modest hikes earlier, not extreme tightening.

Pivotal Quotes: "if hers are some of the best arguments for having the Fed issue of central bank digital currency, then there really aren't any good ones." — George Selgin: Selgin’s summary judgment on Lael Brainard’s speech defending CBDC. "unrealized losses on the SOMA's portfolios equates dollar for dollar with a decrease in the current value of expected SOMA net income." — David Beckworth (citing Bill Nelson): Explanation of why Fed balance-sheet losses have real fiscal implications. "The Fed has no excuse for having talked when COVID broke out about how they probably wouldn't raise rates until 2023 and 24." — George Selgin: Selgin criticizes overly specific forward guidance that boxed the Fed in.

Implications: The episode reinforces skepticism toward CBDCs, highlights the fiscal significance of Fed losses, and underscores that dollar dominance remains structurally strong. For policymakers, the message is to prioritize credible anti-inflation policy, better communication, and careful reserve-regime design.
