Maybe I am wrong but I don’t think there were any “high yield” savings accounts for at least a decade or even more.
All savings accounts I see are mostly below inflation or around the same. Where high yield for me would be at least 1% or 2% above inflation.
Even intermediate or longer term bonds struggle to get 2% real returns.
But yea, "high yield" is a misleading name for savings accounts, and there isn't a huge point to it now, especially after the liquidity rules on government money markets got tighter after dodd frank.
There is still one benefit to having at least a month or two of expenses in a savings account though - FDIC. In an emergency that also crashes your bank, FDIC turnaround is like one business day. SIPC exists for brokerage holdings, but it is glacially slow by comparison.
Of course, changing interest and inflation rates can change that.
Officially.
