I remember when a Credit Union I worked for introduced a Money Market Account (MMA) back in the 1980s. We called it a High Yield Account. Over the past 10 years I’d hesitate to call a MMA at any financial institution a “high yield” savings. The rates are close to zero.
However, the most impressive rate in Utah is the Grand County Credit Union down in Moab. If you’re lucky enough to live in Grand or Emery County you’re eligible. If not, you’ll have to keep your money in one of those “Low Yield” accounts.
