Monetary Policy and Its Effects on Investors
A Look at How Monetary Policy Affects Your Portfolio
Monetary policy is a phrase that gets thrown around a lot in the financial news media, but few investors fully understand what it means.
Monetary policy refers to the techniques that central banks use to control the supply of money, ranging from setting interest rates to purchasing troubled assets. Most central banks around the world are tasked to use these techniques to control inflation and deflation, but some mandates have expanded to include things like controlling the unemployment rate (as in the U.S. Federal Reserve's case).
Some common goals of monetary policy are:
- Price Stability (e.g. inflation/deflation control)
- Economic Growth (e.g. secular rise in GDP)
- Exchange Stability (e.g. low volatility with other currencies)
- Full Employment (e.g. maximized labor resources)
Monetary Policy Tools
Central banks use a variety of different methods to achieve their objectives and control the money supply. The most common techniques employed by central banks are open market operations designed to influence the federal funds rate in the federal funds market - a place where banks keep or borrow their required reserve capital to remain in compliance with banking regulations.
Open market operations influence the interest rates in these markets by buying or selling government securities. Buying government securities creates a cash influx for banks, which can then lend that extra money to other banks and lower interest rates. The opposite is true if the government steps in and starts selling government securities, taking cash out of the market.
While these methods may influence interest rates, modern monetary policy involves a number of other techniques to combat issues when interest rates are already low. These monetary policy tools are usually referred to as "unconventional monetary policy".
Two recent examples of these tools include:
- Quantitative Easing - The purchase of financial assets directly from commercial banks and other private institutions with newly created money in order to inject a predetermined amount of money into the economy more directly.
- Altered Maturity Dates - The shift of debt or other assets held by central banks from short-term to long-term, or long-term to short-term, maturity dates in order to increase or decrease the amount of cash available in the economy.
Monetary Policy & Investors
Many investors know monetary policy best for its immediate effects on the stock market. For instance, the three rounds of quantitative easing announced between 2008 and 2012 led to significant market rallies after they were put in place. Lower interest rates help stimulate the economy by making loans less expensive, while similarly making loans to buy securities on margin cheaper.
Despite these immediate effects, the benefit of monetary policy - particularly unconventional monetary policy - is hotly debated by economists. For instance, many retired individuals living off of pensions or savings are negatively affected by artificially low interest rates since they hold predominantly fixed income securities. Those supporting monetary policy argue the benefits far outweigh these costs.
There have also been a number of central bank failures around the world. For example, in Argentina, Cristina Fernandez de Kirchner's administration was widely criticized by global economists for using the central bank's foreign reserves to fund social programs, while the bank has failed to contain inflation rates that remain stubbornly high by many accounts.
Monetary Policy Announcements
Investors can capitalize on monetary policy decisions in a number of different ways given these well-known dynamics. Meanwhile, leading indicators can provide hints as to future monetary policy decisions, such as Purchasing Managers' Indexes (PMI) and/or Consumer Price Indexes (CPI), which can provide economic health and inflation/deflation data.
Finding monetary policy decisions is a matter of looking in the right places:
And here are some key events to watch around the world:
- ECB M3 Money Supply
- BOE MPC Minutes
- RBA Meeting Minutes
- SNB Monetary Policy Assignment
- RBNZ Announcements
- US Fed Beige Book
- US Fed FOMC Minutes
- BOJ MPB Minutes
International investors generally look at leading indicators to determine when monetary policy is likely to change and then adjust their portfolios accordingly. For example, efforts to lower interest rates could make equities more attractive while rising interest rates could make bonds more attractive. These policies could also be indicative of the health of the overall economy.
