I can't see the benefit of having so much money in the credit union- the interest is very low on saving. The benefits I think of a credit union is if you save regularly you will be able to borrow loans at low interest- many people do this who get loans on a regular basis- particularly people on low income- they save regularly in their local credit union where they become known . People then often borrow for Christmas, for their annual holiday, for a car perhaps and pay back every week. As well as paying back their loan, members are encouraged to keep saving- i.e shares. It works really well like this but as a place for putting your savings I would definitely say there are way better places for return on your money.
