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 crisis.

Explaining Negative Interest Rate Policies (NIRPs)
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 demand, which 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.
- The Swiss government ran a de facto negative interest rate regime in the early 1970s to counter its currency appreciation due to investors fleeing inflation in other parts of the world.
- In 2009 and 2010, Sweden and, in 2012, Denmark used negative interest rates to stem hot money flows into their economies.
- In 2014, the European Central Bank (ECB) instituted a negative interest rate that only applied to bank deposits intended to prevent the Eurozone from falling into a deflationary spiral.
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.
