Reinvestment Risk

Doug Drabik discusses fixed income market conditions and offers insight for bond investors.

There are many advantages and risks associated with any investment. Whether you are buying a stock, a house, a business, or a bond, each investment has unique characteristics that allow an investor to gain from particular investment features with varying risks. Typically the greater the benefit, the greater the risk and conversely, the less the risk, the less the benefit.

Investors often misconstrue a bond with a short maturity as being conservative. The reality is that staying short is neither conservative nor aggressive but rather strategic positioning on future interest rates, just the same as going long in maturity is. If we absolutely “know” that interest rates are going to be lower in 2 years (which we don’t), the riskiest maturity to purchase would be 2 years. We do not want to have to reinvest maturing money at the precise time we know rates will be lower. You could say in this instance that staying short is rather aggressive since the strategy does not align with a known event.

Most consumers understand a similar concept in the housing market. Secondary housing is in a shortage not because people don’t want to move but because they know if they sell, they will lose the very low mortgage interest rate held on their current house and risk having to secure a new loan for a new house at a much higher interest rate. A 30-year $500k mortgage loan at 2.5% is $1,975/month compared to $3,326/month at 7%.
