What are negative interest rates?
Negative interest rates occur when borrowers are credited interest rather than paying interest to lenders. This unusual scenario is most likely to occur during a deep economic recession when monetary policy and market forces have already pushed interest rates to their nominal zero bound.
KEY POINTS:
With negative interest rates, banks charge you interest to keep cash with them, rather than paying you interest.
Negative interest rates might be seen during deflationary periods when people or institutions are inclined to hoard money, rather than spend or lend it.
The negative interest rate is meant to be an incentive for banks to make loans during a period in which they would rather hang on to funds.
