They have been increasing the interest rates to create a recession. The recent bear market is a result of them only increasing rates to .5 back in December. Prior to that they'd been increasing it in increments of .75.
The next 6 months will be interesting. They've said they will increase rates by .25 3 more times. Theyve stated they want to get inflation back to 2%. These minor adjustments are their attempt to create a soft landing.
The good news is that consumers saved money during the pandemic, so that excess savings may drive consumer behavior to the point where demand does not significantly decrease. That's the best case scenario.
Your assertion that the economy is healthy is just wrong. The Fed wouldn't have increased rates to what they are if that were true. Increasing rates to this level would tank a good economy.
