Economy is doing "good" so there is no need. And there is still large risk of inflation coming back. So it is better to keep rates higher. There is yet no real need to lower rates. So better to wait and see.
The idea is that it could help lower inflation as shelter is a large portion of core CPI. It’s not about lowering the prime rate, but having a lower rate for creation of supply, which would exclude all services (80% of the economy).
