The answer is Increase/Increase
As people and businesses become more confident in the economy, they will want to invest more. They will also not be afraid to take out a loan and develop a new unit or buy new land since they are optimistic about the economy and are expect good years ahead.
In the case real interest rates, they will also increase. As businesses and individuals are more confident they will want to invest rather than save money.
While interests rates were pretty low in the last few years to encourage investment, the government will gradually move away from this policy.
