Skanda Amarnath and Preston Mui on the Tribal Transitory Debate and the Future of the Fed's Framework

Episode Summary

Executive Summary: The episode examines the causes of recent U.S. disinflation, arguing that the inflation surge and its reversal were driven by a mix of supply shocks, demand surges, and policy responses rather than a simple transitory/permanent split. Guests Skanda Amanath and Preston Mui also defend a more balanced Fed approach, argue for rate normalization as inflation cools, and make the case that the Fed’s upcoming framework review should better account for nominal spending and labor income.

Main Topics: Disinflation and the ‘transitory’ debate (Priority: 5/5): The conversation reframes the pandemic inflation debate as less about who was right and more about understanding the mix of supply, demand, and timing. The guests argue that the ‘transitory’ label was used in different ways and that much of the debate was people talking past each other. Supply shocks and demand surges in the inflation episode (Priority: 5/5): Amanath and Mui stress that supply disruptions were real—autos, commodities, goods supply chains, and labor-force disruptions—but so was demand, especially in 2021’s reopening and fiscal-driven spending boom. They emphasize that both sides mattered. Labor markets, inflation, and the Fed’s response (Priority: 4/5): They argue the Fed has become less inclined to treat inflation as requiring mass unemployment, which they see as a positive shift versus earlier episodes like 2008. They credit the Fed for avoiding the most extreme unemployment-focused reaction during the latest inflation surge. Interest-rate normalization in 2024 (Priority: 4/5): The guests make a case for cutting rates as inflation falls, even absent a recession, to reduce nonlinear downside risks and restore a more normal policy stance. They argue the Fed should move earlier rather than waiting for visible deterioration. The role of fiscal policy and nominal spending (Priority: 4/5): They acknowledge massive fiscal support and strong nominal spending, but say the key question is the mechanism and magnitude, not just the presence of big numbers. They push back against simplistic claims that fiscal stimulus alone explains inflation. Fed framework review and alternative targets (Priority: 5/5): The discussion closes with support for nominal GDP or gross labor income targeting as a better framework for handling supply shocks and noisy price data. They argue nominal aggregates are easier to interpret and may improve communication and policy consistency.

Key Arguments: The ‘transitory’ debate was unproductive because participants used the term differently: some meant short-lived in time, others meant not driven by labor-market slack or expectations. Inflation should be evaluated through the welfare trade-off it imposes, not only through a moralized transitory/permanent lens; avoiding recession and mass unemployment matters. Supply shocks were clearly present in autos, goods, and commodities, but demand also surged through reopening, fiscal transfers, and a rapid labor-market recovery. The rise in rent inflation is a major indicator of demand pressure, especially because market rents surged in 2021 and then later cooled. Fed tightening may have helped cool some parts of the economy, but the evidence linking the rate-hiking cycle directly to disinflation in consumption is mixed and not decisive. Policy normalization is appropriate when inflation is falling and the labor market remains healthy; waiting for visible deterioration creates nonlinear risks. The Fed should not wait until unemployment or financial instability is obvious, because these risks can snowball quickly once they emerge. Nominal spending and labor income are more stable and policy-relevant guides than trying to infer the cause of each monthly price print. A nominal GDP or nominal labor income target would better capture the macro balance between spending and supply capacity than inflation-only targeting. Communication around core non-housing services and other price subcomponents is too opaque for effective public understanding; nominal aggregates are clearer.

Data Points: CPI inflation peak: 9% - Referenced as the summer 2022 CPI peak before disinflation set in. Disinflation magnitude: About 6 percentage points - The transcript notes inflation has fallen roughly six points from the peak. PCE nowcast accuracy: 95% to 99% - Employee America says its PCE nowcasts can map most of official PCE with high accuracy. U.S. government borrowing during pandemic: About $5 trillion - Used to illustrate the scale of fiscal support and potential demand effects. Helicopter-drop / Fed-financed portion: About $3 trillion - A subset of the pandemic borrowing was described as financed through the Fed. Nominal GDP gap vs trend: About $2 trillion higher - Used as evidence that nominal spending became unusually elevated after the pandemic. Market-based PCE gap vs pre-pandemic trend: About $1.7 trillion higher - Offered as an alternative spending measure showing an unusually large nominal expansion. Real GDP growth: 3% growth over the past four quarters - Cited to support the argument that output and supply recovered strongly. Productivity growth swing: -2% YoY in 2022 Q3 to +2% four quarters later - Used to show an unusual macro swing consistent with large shock dynamics. Fed funds rate: 5.33% - Described as the current significantly restrictive policy rate during the normalization discussion. Core PCE, 6-month annualized: Below 2% - Used by the guests to argue inflation has cooled more than many expected. Core PCE, 12-month ending November: 3.2% - Mentioned as the latest trailing-year reading at the time of the discussion. Terminal funds rate in SEP Dec. 2022: 5 1/8% - Referenced as a prior Fed projection now being surpassed by disinflation progress. Potential unemployment path cited by hawks: 4.6% - Mentioned as an example of the Fed’s earlier willingness to tolerate some labor-market weakening. Larry Summers unemployment estimate: 7.5% - Used as an example of more extreme calls for unemployment to reduce inflation. Korean War inflation comparison: Higher than current episode and later fell without a recession - Invoked as a historical analogy for inflation declining without a severe downturn. Taylor-rule reaction coefficient: 150 basis points per 100 basis points change in inflation - Referenced when discussing proportional interest-rate responses.

Pivotal Quotes: "“the real question I think we should be asking is, was the inflation worth it?”" — David Beckworth: Introduces a welfare-based framing of the inflation episode beyond transitory vs. permanent. "“don’t be a supply denialist”" — Skanda Amanath: A direct argument that supply shocks were undeniably part of the inflation surge and should not be minimized. "“the downside risks are nonlinear and somewhat unpredictable in terms of how they materialize”" — Preston Mui: Explains why the Fed should normalize rates before visible deterioration becomes severe.

Implications: Listeners should expect a more nuanced view of inflation and Fed policy: supply and demand both mattered, the labor market remains central, and a future framework may shift toward nominal spending or labor-income targeting to improve policy in real time.
