Update 4/26/08: CD rates went up! The new 60-mo and 36-mo CD yields for $100K minimum are 5.30% APY and 4.96% APY. The title has been modified to reflect this change.

Northwest Federal Credit Union seems to be one of the few institutions which raised CD rates at the start of April. The new certificate rates include a 4.79% APY for a 5-year term and 4.36% APY for 3 and 4 year terms. These require a minimum deposit of $100,000. The yields for a $25K minimum are 10 basis points lower and about 15 basis points lower for a $2,500 minimum.
My first post on this credit union was last November when they were offering a 6% 18-month CD. In February they came out with some competitive long term CD rates. However, it seemed like every week after that, the rates kept declining. So don't expect these current rates to remain through April.
When I first posted on this credit union in November, it appeared anyone could qualify by joining the National Wildlife Federation. However, the credit union's board changed this eligibility criteria to only include employees of National Wildlife Federation. So there's no longer an easy way to qualify for credit union membership. The credit union's field of membership is primarily limited to Select Employee Groups. Please see their Who Can Join page for more details. There is a long list of member companies. Membership requires a minimum deposit of $5 into your share savings account.
Branches are located in the Virginia cities of Chantilly, Herndon and Vienna. The credit union is federally insured by the NCUA (Charter # 5500). It's a large credit union with $1.51 billion in assets and 92,177 members.
