What is a 'Negative Interest Rate Policy (NIRP)'

A negative interest rate policy (NIRP) is an unconventional monetary policy tool whereby nominal target interest rates are set with a negative value, below the theoretical lower bound of zero percent.

BREAKING DOWN 'Negative Interest Rate Policy (NIRP)'

During deflationary periods, people and businesses hoard money instead of spending and investing. The result is a collapse in aggregate demand which leads to prices falling even farther, 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. (See also: How Interest Rates Can Go Negative.)

A negative interest rate means 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.

Examples

An example of a negative interest rate policy would be to set the key rate at – 0.2%, such that bank depositors would have to pay two-tenths of a percent on their deposits instead of receiving any sort of positive interest.

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 move their deposits into cash.

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 cut down interbank loans.  To stay on top of the latest finance and investing lingo, subscribe to our Term of the Day newsletter.
