US money-market yields haven't been this juicy for 22 years, thanks to the Fed's interest-rate rises

• The Fed has lifted interest rates to the highest level in two decades in its war against inflation. 
• While that made borrowings more expensive, it also boosted yields on cash and cash-like assets to historic highs – making them attractive for retail investors. 
• Over $472 billion has flowed into money market funds since mid-March, as the popularity of such investments surged.

Last week, the Federal Reserve increased interest rates to levels not seen for 22 years. From mortgages to car loans, borrowing costs have climbed to historic highs and, for many experts, a US recession looms on the horizon.
