After segmenting historical financial markets into five eras and twenty periods, we have found that market returns on Stocks, Bonds, and Bills vary significantly based on four powerful forces: Trade, War, Inflation, and Government. These forces — the Four Horsemen of Finance — offer a compelling lens through which to understand the rise and fall of returns across time and geography. At Finaeon, we call this the TWIG Theory of Financial Markets:
Break any part of the TWIG, and market returns can suffer.
Trade
Free trade fuels economic growth and investor confidence. Conversely, restrictions on trade — such as tariffs, import substitution policies, or economic autarky — tend to dampen long-term market returns.
Barriers to trade may support domestic companies in the short term, but they limit international sales opportunities and weaken overall efficiency. Currency manipulation can further hinder trade, and throughout history — particularly between 1914 and 1981 — such policies reduced returns in many markets.
Successful economies, like the Anglo-American and East Asian countries, typically embrace open trade. By contrast, nations like those in South America, which have relied heavily on protectionism, have often seen stagnation or decline in returns.
War
War shifts economic activity from production to destruction. It disrupts supply chains, redirects labor and industry toward military output, and reduces consumer availability of goods. Government interventions during wartime often cap corporate profits, while debt defaults and inflationary financing strategies wreak havoc on bondholders.
While neutral nations that supply goods may temporarily benefit, those engaged in conflict suffer across all asset classes. Returns on Stocks, Bonds, and Bills tend to falter during wars, and recovery is often delayed by the dislocation and rebuilding that follows.
Inflation
Inflation is a devastating force for fixed-income investors. When inflation accelerates — whether modestly, severely, or to hyperinflationary levels — the real returns on Bonds and Bills are quickly eroded.
Stocks may offer relative protection, but mostly because fixed-income returns drop so sharply. Even equities can fail to keep pace with high inflation, leading to real losses for investors. Some countries have seen inflation wipe out over 90% of real investment value. While stocks may eventually recover once inflation stabilizes, the damage to Bonds and Bills is often irreversible.
Government
Governments play a dual role in financial markets: they can either foster innovation and investment or stifle it through control and overreach.
Excessive government intervention — including nationalization of industries, excessive regulation, or threats of asset seizure — dampens entrepreneurial activity. The fear of socialism or state interference can depress market returns for decades, even if no direct action is taken. Historical examples from Communist regimes in Russia, China, and Eastern Europe show how investors lost everything when property rights were eliminated and assets were seized without compensation.
Wrap-Up
Countries where market capitalization exceeds government debt consistently outperform those where government debt overshadows equity markets. The data shows that economic freedom, protected private property, and restrained government involvement in industry are vital ingredients for long-term market success.
Although many other factors can influence long-term returns, these four key forces — Trade, War, Inflation, and Government — consistently explain the broad differences in financial performance across countries and periods. That’s why, in our exploration of historical financial data at Finaeon, we pay special attention to each of these Horsemen when analyzing market behavior across eras and within individual nations.
