Arizona Federal Credit Union continues to offer a special 15-month share certificate. They've recently increased the top yield to 5.85% APY for a minimum deposit of $100k. The lower deposit rates are the same as I had reported in July. The lower yields range from 5.50% APY for a $500 minimum, 5.60% APY for a $50k minimum and 5.65% APY for a $75k minimum.
Field of membership includes anyone who lives, works, worhships or attends school in Maricopa County, Pinal County or the City of Tucson. Membership requires a minimum $25 in the share savings account.
The credit union is federally insured by the NCUA (Charter # 1747). It's a large credit union with $1.76 billion in assets and 214,351 members.
Thanks to the reader Michael who sent me email on this rate update.
