How Do Changes In The Velocity Of Money, As Measured By The M2 Money Supply, Affect The Relationship Between The 10-year Treasury Yield And The S&P 500's Price-to-earnings Ratio, Particularly During Periods Of Monetary Policy Regime Shifts, Such As The Transition From A Low-interest-rate Environment To A Rising-rate Environment?

Changes in the velocity of money, as measured by the M2 money supply, can significantly impact the relationship between the 10-year Treasury yield and the S&P 500's price-to-earnings (P/E) ratio, particularly during periods of monetary policy regime shifts. Here's a detailed breakdown of how these dynamics interact:

1. Understanding the Components

  • Velocity of Money: The velocity of money measures how quickly money is circulating in the economy. It is calculated as the ratio of GDP to the money supply (M2). A rising velocity indicates that money is being used more efficiently or that economic activity is increasing relative to the money supply.
  • 10-Year Treasury Yield: This is a key benchmark for long-term interest rates and reflects market expectations about inflation, economic growth, and monetary policy.
  • S&P 500 P/E Ratio: This ratio reflects investor sentiment and valuations in the stock market. It is influenced by interest rates, earnings growth, and risk appetite.

2. Impact of Velocity of Money on the Economy

  • Rising Velocity of Money: When the velocity of money increases, it can stimulate economic activity even if the money supply (M2) is stable or growing slowly. This can lead to higher inflation, increased borrowing costs, and a stronger demand for goods and services.
  • Falling Velocity of Money: A decline in velocity suggests that money is sitting idle, leading to slower economic growth and potentially deflationary pressures.

3. Relationship Between Velocity of Money and Monetary Policy Regimes

During periods of monetary policy regime shifts, such as the transition from a low-interest-rate environment to a rising-rate environment, the velocity of money plays a critical role in how financial markets respond:

a. Low-Interest-Rate Environment

  • Low Rates and High Money Supply: In a low-interest-rate environment, central banks often expand the money supply (M2) to stimulate economic growth. If velocity is low (as seen in the post-2008 era), the excess money supply may not translate into higher inflation, allowing the central bank to maintain accommodative policies.
  • Impact on 10-Year Treasury Yields: Low interest rates and low velocity keep Treasury yields suppressed, as inflation expectations remain subdued.
  • Impact on S&P 500 P/E Ratio: Low rates make equities more attractive, leading to higher P/E ratios as investors discount future cash flows at a lower rate.

b. Transition to a Rising-Rate Environment

  • Rising Rates and Increasing Velocity: When monetary policy shifts to a rising-rate environment, central banks tighten the money supply or allow it to grow more slowly. If velocity also increases, the combined effect can lead to higher inflation and faster economic growth.
  • Impact on 10-Year Treasury Yields: Rising rates and higher velocity increase inflation expectations, driving up the 10-year Treasury yield. This reflects a stronger economy and higher borrowing costs.
  • Impact on S&P 500 P/E Ratio: Rising rates make equities less attractive on a relative basis, leading to downward pressure on the P/E ratio. However, if earnings growth accelerates due to higher economic activity, the P/E ratio may remain elevated or even rise.

4. Historical Context and Empirical Observations

  • 1970s-1980s: During the high-inflation era, rising velocity of money and tight monetary policy led to sharply higher Treasury yields and volatile equity markets. The P/E ratio was compressed due to high inflation and interest rates.
  • 1990s-2000s: The decline in velocity during this period allowed central banks to maintain lower rates without triggering high inflation. This supported higher P/E ratios and lower Treasury yields.
  • Post-2008 Era: The Federal Reserve's quantitative easing programs expanded M2 significantly, but velocity remained low due to weak demand and risk aversion. This kept Treasury yields low and supported high P/E ratios despite slow economic growth.

5. Current Implications

  • Rising-Rate Environment: If the velocity of money increases alongside rising interest rates, the 10-year Treasury yield is likely to rise more sharply, and the S&P 500 P/E ratio may face downward pressure unless earnings growth accelerates significantly.
  • Falling Velocity: Conversely, if velocity remains low despite rising rates, the impact on Treasury yields and the P/E ratio may be muted, as economic growth and inflation expectations remain subdued.

6. Conclusion

The velocity of money amplifies or moderates the effects of monetary policy shifts on financial markets. During the transition from a low-rate to a rising-rate environment:

  • A rising velocity of money tends to push up the 10-year Treasury yield more sharply and reduce the S&P 500 P/E ratio.
  • A falling velocity of money can cushion the impact of rising rates, keeping Treasury yields lower and supporting higher P/E ratios.

Thus, understanding velocity is crucial for analyzing how monetary policy regime shifts influence the relationship between interest rates and equity valuations.
