On the one hand…if you can borrow money cheaply, you are more likely to expand your business and buy a house or a car. Especially during a recession, low interest rates can encourage business expansion and consumer loans. As a source of economic stimulus, many believe that zirp is desirable.
On the other hand…households and businesses that have income based on interest rates are suffering. Historically, savers have been able to earn an average of 3 percent. Now, they receive close to 0% when they invest in such financial instruments as short term treasury securities, The problem? If we look at what they could have earned, savers have lost a total of $350 billion annually–350 billion that would have been saved or spent.
For countries also, there are two sides. According to the Bank for International Settlements (BIS), countries with zirp, such as the U.S., can borrow money very cheaply. Also though, other nations such as Australia that pay higher interest rates, can lure investors away from lower yielding securities elsewhere.
The Economic Lesson
The interest rate is the price of money. When an economy experiences rapidly rising prices, central banks usually increase the price of money to constrain spending. Recession, by contrast, requires a lower price of money (interest rate) in order to stimulate business and consumerr spending.
The Federal Reserve has three traditional tools to affect interest rates in the U.S. 1) It can change the amount of money that banks have to keep in reserve. 2) It can change the interest rate that it charges banks when they borrow the Fed’s money. 3) It can enable banks to have less to lend by selling them securities or more money to lend by buying securities from banks.
