What Is a Negative Interest Rate Policy (NIRP)?
A negative interest rate policy (NIRP) is an unconventional monetary policy tool employed by a central bank whereby nominal target interest rates are set with a negative value, below the theoretical lower bound of zero percent. A NIRP is a relatively new development (since the 1990s) in monetary policy used to mitigate a financial crisisand has only been officially enacted under extraordinary economic circumstances.
- A negative interest rate policy (NIRP) occurs when a central bank sets its target nominal interest rate at less than zero percent.
- This extraordinary monetary policy tool is used to strongly encourage borrowing, spending, and investment rather than hoarding cash, which will lose value to negative deposit rates.
- Officially set negative rates have been seen in practice following the 2008 financial crisis in several jurisdictions such as in parts of Europe and in Japan.
Negative Interest Rate Policy (NIRP)
Explaining Negative Interest Rate Policies
A negative interest rate means that the central bank (and perhaps private banks) will charge negative interest. Instead of receiving money on deposits, depositors must pay regularly to keep their money with the bank. This is intended to incentivize banks to lend money more freely and businesses and individuals to invest, lend, and spend money rather than pay a fee to keep it safe. This happens during a negative interest rate environment.
During deflationary periods, people and businesses hoard money instead of spending and investing. The result is a collapse in aggregate demandwhich leads to prices falling even further, a slowdown or halt in real production and output, and an increase in unemployment. A loose or expansionary monetary policy is usually employed to deal with such economic stagnation. However, if deflationary forces are strong enough, simply cutting the central bank’s interest rate to zero may not be sufficient to stimulate borrowing and lending.
The Theory Behind Negative Interest Rate Policy (NIRP)
Negative interest rates can be considered a last-ditch effort to boost economic growth. Basically, it’s put into place when all else (every other type of traditional policy) has proved ineffective and may have failed.
Theoretically, targeting interest rates below zero will reduce the costs to borrow for companies and households, driving demand for loans and incentivizing investment and consumer spending. Retail banks may choose to internalize the costs associated with negative interest rates by paying them, which will negatively impact profits, rather than passing the costs to small depositors for fear that, otherwise, they will have to move their deposits into cash.
Real World Examples of NIRP
An example of a negative interest rate policy would be to set the key rate at -0.2 percent, such that bank depositors would have to pay two-tenths of a percent on their deposits instead of receiving any sort of positive interest.
Though fears that bank customers and banks would move all their money holdings into cash (or M1) did not materialize, there is some evidence to suggest that negative interest rates in Europe did cut down interbank loans.
There are some risks and potential unintended consequences associated with a negative interest rate policy. If banks penalize households for saving, that might not necessarily encourage retail consumers to spend more cash. Instead, they may hoard cash at home. Instituting a negative interest rate environment can even inspire a cash run, triggering households to pull their cash out of the bank in order to avoid paying negative interest rates for saving.
Banks that wish to avoid cash runs can refrain from applying the negative interest rate to the comparatively small deposits of household savers. Instead, they apply negative interest rates to the large balances held by pension fundsinvestment firms and other corporate clients. This encourages corporate savers to invest in bonds and other vehicles that offer better returns while protecting the bank and the economy from the negative effects of a cash run.
