Bryan Taylor: There Is No Equity Risk Premium | #635

Dr. Bryan Taylor, founder of Global Financial Data, discusses his TWIG framework (Trade, War, Inflation, Government) for analyzing historical market returns across centuries. He argues there is no persistent equity risk premium, warns about the 2030s based on a 30-year cycle pattern, and draws on global financial history to contextualize current U.S. market conditions.

Summary

Dr. Bryan Taylor, a financial historian and founder of Global Financial Data (Finneon), joins the Meb Faber Show to discuss insights from his new book 'Five Financial Eras' and decades of research into global financial markets spanning nine centuries. The conversation centers on his TWIG framework — an acronym for Trade, War, Inflation, and Government — which he argues are the four primary determinants of investment returns across history. When all four factors are favorable (free trade, no war, low inflation, minimal government intervention), investors receive the highest returns, as seen in the 1980s and 1990s. When all four are unfavorable, as in the 1910s during World War I, returns can be negative. Taylor assesses current U.S. policy as poorly aligned with the TWIG framework, citing tariffs, involvement in a war with Iran, rising inflation, and mixed government signals.

Taylor presents one of his most controversial claims: that there is no persistent equity risk premium. He argues that bond and stock returns move independently of one another and that the apparent premium is an artifact of specific historical periods rather than a structural feature of markets. He supports this with data from 27 countries over two centuries, noting that in many countries and many 10-year periods, bonds have outperformed equities. He emphasizes that the 40-year bond bull market from 1981 to 2021 — driven by declining interest rates — cannot be expected to repeat, and that investors anchored to that period will draw incorrect conclusions.

Taylor discusses a 30-year cycle in U.S. stock market performance, noting that the 1950s, 1980s, and 2010s were strong decades while the 1940s, 1970s, and 2000s were poor. He warns that this pattern, if it continues, does not bode well for the 2030s. He also examines the nearly 70-year period from the early 1910s to 1981 during which U.S. bonds produced negative real returns — a fact largely unknown to modern investors.

The conversation covers the historical shift in investor focus from bonds (the dominant asset class in the 1800s) to equities in the 20th century, and then to index funds and ETFs in the 21st century. Taylor notes that dividend yields were historically higher than bond yields until the 1950s, and explains that the decline in dividend yields is largely explained by the dramatic increase in stock market capitalization relative to GDP, not necessarily deteriorating fundamentals. He also discusses the relationship between government debt and stock market capitalization, arguing that when stock market cap exceeds government debt, it is generally positive for stocks.

Taylor highlights historical market wipeouts, primarily in Russia (1917) and China (1949), as cases where government-imposed collapses led to total investor losses, contrasting these with typical bear markets from which economies eventually recover. He also touches on currency history, previewing an upcoming book documenting the currency histories of every country in the world, noting that the U.S. dollar and Swiss franc have been among the most stable currencies over the past century. Throughout, Taylor emphasizes the importance of looking at financial history in distinct eras rather than as one long continuous dataset.

About this episode

Today’s guest is Bryan Taylor, founder and chief economist of Finaeon, which has the most comprehensive database of historical financial market data in the world. He's just published Five Financial Eras: How Financial Markets Transformed the World. In today’s episode, Bryan explains his TWIG framework of trade, war, inflation, and government, and how their combination drives returns across centuries of market history. He challenges the belief in a fixed equity risk premium and revisits seven decades of negative real bond returns. To close, Bryan explains why the post-1981 playbook no longer applies.

Key Insights

  • Taylor argues that the equity risk premium does not reliably exist because bond and stock returns move independently of one another, and any apparent premium is a product of specific historical conditions rather than a structural market feature.
  • Taylor claims that the 1941–1981 interest rate pyramid — during which 10-year government bond yields rose from ~2% to ~15-16% — produced nearly 70 years of negative real returns for U.S. bond investors, a fact he says most modern investors are unaware of.
  • Taylor assesses current U.S. policy as misaligned with all four TWIG factors simultaneously: tariffs restrict trade, the U.S. is involved in a war with Iran, inflation is rising, and government intervention is mixed — conditions historically associated with the lowest investor returns.
  • Taylor identifies a 30-year cycle in U.S. stock market performance (strong decades: 1950s, 1980s, 2010s; poor decades: 1940s, 1970s, 2000s) and warns that if the pattern holds, the 2030s are likely to produce poor returns.
  • Taylor argues that declining dividend yields in the U.S. are not necessarily a bearish signal — they are largely explained by the dramatic expansion of stock market capitalization relative to GDP, and when adjusted for this, dividend distributions have not changed as dramatically as raw yield figures suggest.
  • Taylor contends that when a country's stock market capitalization exceeds its government debt level, it is generally positive for stocks, and that the post-1980 period where both have risen simultaneously is historically unusual and bears watching.
  • Taylor observes that the Anglo countries (U.S., UK, Canada, Australia, New Zealand) have consistently controlled 70–80% of global stock market capitalization throughout history, and that predictions from 20 years ago about emerging markets overtaking developed markets have not materialized.
  • Taylor notes that the Russian (1917) and Chinese (1949) market collapses were structurally different: the Russian wipeout was sudden and unexpected, while Chinese investors had 12 years to gradually exit as geopolitical conditions deteriorated, reducing Shanghai market cap from ~$1 billion to ~$50 million by closure.

Transcript

Unfortunately, current government policy is not following the twig theory. I mean, they're following restrictions on trade through tariffs. We're currently involved with a war in Iran. Inflation is picking up. Stock markets provided double-digit returns in the 1920s, 50s, 80s, the 2010s. And if you follow that logic, the 2040s are going to be providing great returns. On the other hand, that does not bode well for the 2030s. There was this period almost 70 years, essentially the majority of the 20th century where U.S. bonds had a negative real return. I mean, that's absolutely true. real return i mean that's absolutely true welcome to a special series of the meb faber show on the past present and future…
