The neutral interest rate is estimated to be between 2.5% and 2.75%, with a possibility of reaching 4.25% if inflation does not decrease.

Now, it's assumed to be somewhere between 2 1/2 and 2.75%, which means there's a good chance we could get there by the end of the year. But others argue that this assumes that inflation comes down. And if it doesn't, they may need to increase rates even further with one analysis calling for rates to hit 4.25%. 25%"
