In order to facilitate economic growth, the public need to be confident that banks, non-bank deposit takers (NBDTs) and insurers can and will continue to provide these services, and that the payment and settlement systems will work as expected.
Conversely, balanced budgets or at least low deficits and low levels of debt allow for lower taxes and facilitate private investment and also government investment. Low interest rates give the public sector more scope for investment to improve the public infrastructure.
