SAN JOSE, Calif. – Technology Credit Union has started offering an adjustable rate certificate account designed to provide investors a high rate of return that fluctuates with rising rates. Tech CU's Adjustable Rate Certificate Account is available in 6-month and12-month terms, each adjusting on the first day of the new quarters respectively to the 6-month and 12-month LIBOR indices. The Certificate is subject to change quarterly, but will never adjust below the quoted start rate, the credit union said. A minimum deposit of $10,000 in new deposit money is required. The offer will be available to existing and new Tech CU members for a limited time only and other restrictions may apply. The certificate is targeted at those, especially "Silicon Valley professionals," here who want to position their short-term investments in anticipation of a rising rate environment, said Ted Thames, Technology CU's vice president of strategic development. The credit union serves 75,000 members and has $1.1 billion in assets.
