Monetary Illusion

Investors who analyze the financial world through the lens of the business cycle and use market ratios to allocate their portfolios among the four asset classes of the Permanent Brown Portfolio understand that, beyond the constant noise generated by Wall Street and its parrots, there are two key financial ratios that shape the business cycle across its four quadrants. Additionally, one ratio has historically served as a leading indicator of shifts between economic booms and busts over time: the valuation of a country's stock market relative to the price of gold, measured against its 7-year moving average. This ratio, often referred to as the indicator of monetary illusion, provides critical insights into the economy's health and direction.

Monetary illusion occurs when individuals perceive their wealth, income, or purchasing power based solely on nominal values, disregarding the effects of inflation or deflation. This cognitive bias can lead to flawed financial decisions, such as mistaking nominal wage increases for real gains in purchasing power, even when inflation erodes actual income. On a broader scale, monetary illusion influences economic behaviour, affecting consumption, savings, and investment patterns. For example, during inflationary periods, consumers may feel wealthier due to higher nominal wages or asset prices, even if there is no real increase in economic value. Similarly, businesses might misinterpret rising revenues as improved performance without accounting for inflation-adjusted profitability. Policymakers may also exploit this illusion by implementing inflationary measures to stimulate spending, masking the long-term erosion of purchasing power.
