How the Biggest Bull Market Could Go on for a Whole Lot Longer

Episode Summary

Executive Summary: The episode is a rebuttal to claims that the bond bull market is approaching a historic collapse. Srinivas Tiruvedantai argues that long-run analogies to pre-fiat eras are misleading, that today’s labor markets and global spare capacity are far looser than in the inflationary 1960s-70s, and that balance-sheet leverage—not just inflation—drives bond risk. He still sees near-term yield pressure from fiscal stimulus, but expects yields to fall dramatically in the next recession.

Main Topics: Rebuttal to the 'bond market massacre' thesis (Priority: 5/5): The hosts revisit a prior episode with Paul Schmelzing and present Srinivas Tiruvedantai’s opposing view: that a catastrophic bond sell-off is not imminent because historical analogies are being overstretched. Why pre-fiat bond history is a poor comparison (Priority: 5/5): Tiruvedantai argues that 800 years of bond history are not comparable to today because most of that period involved sovereign credit risk tied to gold convertibility; modern fiat systems change the nature of sovereign default and rate risk. Labor slack and the absence of a 1960s-style wage-price spiral (Priority: 5/5): He says inflation requires tight labor markets, labor bargaining power, and capacity constraints. Today’s economy has substantially more slack than the late 1960s, making sustained inflation less likely. Balance sheets and financial fragility as the real transmission channel (Priority: 4/5): The discussion emphasizes that large private-sector balance sheets make the economy more sensitive to interest-rate increases through debt service, asset valuations, and wealth effects, unlike in the 1960s. Policy, politics, and inflation (Priority: 4/5): Tiruvedantai argues inflation is not purely a monetary phenomenon; it is shaped by political choices, labor dynamics, and central bank tolerance for inflation, making the Fed less all-powerful than common models imply. Trump-era fiscal stimulus as a short-term bond risk (Priority: 3/5): He says proposed fiscal stimulus, tax cuts, and infrastructure spending could lift inflation expectations and yields in the near term, prompting his center to reduce bond exposure temporarily. Long-run bond market outlook remains bullish, but not painless (Priority: 4/5): Despite near-term risks, he forecasts much lower Treasury yields in the next recession and suggests the bull market may continue unless private balance sheets deteriorate materially or policy changes become much more aggressive.

Key Arguments: Long historical comparisons are misleading because most pre-World War II bond history was shaped by gold-standard sovereign credit risk, not fiat-currency dynamics. A sustained rise in inflation requires tight labor markets, strong bargaining power, capacity constraints, and a Fed willing to accommodate inflation; those conditions are weaker today than in the late 1960s. The unemployment rate understates slack today because participation is lower than in the 1960s, when prime-age male participation and employment were much tighter. Global labor and capacity conditions are looser now than in the 1960s; then, Germany and Japan had extremely low unemployment and capacity utilization was above 90%, supporting wage-price pressure. Big private-sector balance sheets make the economy more rate-sensitive because higher rates hit debt service, valuations, and borrowing capacity, creating negative feedback loops. Inflation is better understood as political and institutional than purely monetary; the Fed cannot mechanically target a precise inflation rate in a vacuum. Trump-style fiscal stimulus could move Treasury yields upward in the short term, especially via reflation expectations. The longer-term bond bull market is not necessarily broken; in the next recession, yields could fall well below current levels. The bond market bull ends when private balance sheets become lean and safe assets become abundant relative to risky assets, not simply when inflation fears rise.

Data Points: Historical comparison length: 800 years - Paul Schmelzing’s long-run bond history analogy, discussed as the basis of the bearish thesis. Fiat currency era: 40 years - Tiruvedantai argues modern fiat-money conditions have existed only about this long, limiting historical comparability. Post-gold-standard comparison window: 70 years - He says even including post-1934 gold-standard history only gives a limited comparable era. US unemployment in late 1960s: less than 4% - Used to illustrate how tight the labor market was in the inflationary period. Prime-age male labor participation in late 1960s: north of 90% - Evidence that labor slack was minimal in the 1960s. Germany unemployment in the period: sub-1% - Shows the extreme tightness of developed-world labor markets in the 1960s. Japan unemployment in the period: less than 2% - Another example of unusually tight global labor conditions. Capacity utilization in the 1960s: north of 90% - Supports the argument that there was little spare industrial capacity then. Current 10-year Treasury yield: 2.48% - Yield level cited while discussing the long-term bond bull market. Early-1980s 10-year yield peak: around 16% - Historical reference point for the start of the long bond rally. Forecast 10-year yield in next recession: below 1%, possibly 0.5% - Tiruvedantai’s projection for the next cyclical low in yields. Forecast 30-year Treasury yield in next recession: 1.5% - His expected level for longer-duration Treasury yields. Potential Trump stimulus size: $300 billion to $600 billion - Estimated range of possible fiscal stimulus discussed as a near-term bond-market driver. Corporate tax cuts estimate: $150 billion to $200 billion - Part of the proposed fiscal package that could affect yields. Personal tax cuts estimate: $400 billion - Another element of the proposed fiscal stimulus cited as large enough to matter. Reduced bond position: temporary cut - The Jerome Levy Forecasting Center reportedly reduced bond exposure due to anticipated stimulus and reflation. Private-sector balance sheets: record asset/GDP levels - Used to argue the economy is highly leveraged and sensitive to rate increases. Private-sector debt: near-record debt/GDP - Supports the claim that higher rates can trigger painful feedback effects.

Pivotal Quotes: "There is no bond market disaster in the offering." — Srinivas Tiruvedantai: Core rebuttal to the prior bearish bond-market thesis. "Inflation is always and everywhere a political phenomenon." — Srinivas Tiruvedantai: His argument that inflation is shaped by institutions, labor power, and policy choices rather than just money supply. "The economy is no longer functioning like a normal economy." — Srinivas Tiruvedantai: He uses this to describe how oversized balance sheets amplify rate shocks and feedback loops.

Implications: Listeners should see bond-market risk as path-dependent: near-term stimulus could lift yields, but the bigger issue is fragile balance sheets and recession dynamics. The long-run bull market may persist until leverage and policy regimes change materially.
