6.60% 60-Month CD at a Maryland CU (NRL).

NRL Federal Credit Union is offering a 6.60% APY 5-year certificate special for the month of July. There's a $500 minimum deposit. The special rate is also available in an IRA. Application can be done online.

If interest rates hikes end this year, it might be time to consider locking in some of your money into a high yield long term CD.

The field of membership includes employees or immediate family members of the Naval Research Lab and several other employers within the credit union's Select Employees Group. See site for details.

Branches are located in Oxon Hill and Waldorf, Maryland and in Washington DC.

The credit union is NCUA insured. It has assets of $339 million and 21,000 members.

Thanks to the reader who emailed me this special.
