Low interest rates widen the gap between Main Street and Wall Street

In This Article:

Is there no end to the absurdity of our debt culture? For most of the past 12 years, we have lived in an era of zero interest rate policy, or “ZIRP.” Designed to stimulate more economic activity by making it cheap to borrow, ZIRP has instead inflated the value of financial assets, encouraged unprecedented levels of public and private sector borrowing, and made the rich even richer - all while delivering tepid growth and stagnant wages in the “real economy.”

Now President Trump and others are escalating calls for the Fed to utilize negative rates, or “NIRP,” as a way to double down on this spent policy and actually pay borrowers to borrow and penalize savers when they save. But NIRP has been tried in Japan and Europe, and it has been unsuccessful in stimulating their economies, as growth in both regions has lagged even our modest economic gains. Thankfully, the Fed so far has resisted going this route.

When central banks lower rates on safe assets like government securities, they make riskier assets like stocks more attractive in comparison. Stocks are generally valued based on their expected future returns relevant to risk-free assets. So when rates on Treasuries go down, stock values go up.

The Federal Reserve's latest financial stability report noted that investors appear to be taking on higher premiums for holding risky corporate equities when looking at the spread between forward earnings-to-price ratios on S&P 500 firms and the real yield on the U.S. 10-year Treasury.

No real underlying value has been created. It’s just math. Stock prices further benefit from increased demand, as investors leave low-yielding bonds for higher return equities. The ability of corporations to issue cheap debt to finance dividend increases and stock buybacks also contributes to elevated stock prices. Low interest rates have been key to the stock market’s meteoric rise over the past decade. The Fed’s stepped-up actions to implement ZIRP through expanded lending, and bond purchases help explain why stocks have rebounded so quickly during the pandemic.

Corporations win with low rates

Because the overwhelming majority of stocks are owned by the wealthiest Americans, this boost in stock prices and other risk assets primarily inures to their benefit. But wealthy investors want to invest their money, not spend it. So their gains do not translate into increased consumption, which would support real economic growth. Proponents of low to negative rates argue that there is still a “Main Street” benefit in the form of lower borrowing costs. True, ZIRP has helped higher income households with good credit histories borrow cheaply. But low and middle income families with less stellar credit records too often pay higher, “risk-based” rates.

In any event, these families need good jobs and wages, not more debt burdens. And low rates have done precious little to support labor markets. Low rates have also hurt working families’ ability to accumulate wealth as they do not own stocks and must keep what meager savings they have in low yield bank accounts. Current and future retirees are also put at risk as insurance companies and pension plans have trouble generating sufficient returns to fund pension and annuity obligations.
