The Oregon Short Term Fund, known as the OSTF, is managed by the Oregon State Treasury to keep taxpayer dollars safe and to help governments of all sizes to stretch public funds.

The OSTF enables governments to earn a rate of return on money between when revenue is received and when the money is needed to pay bills. The rate is determined by Treasury staff based on market conditions and yield for fixed income securities such as government and corporate bonds.

Because the OSTF is made up of government operating money, it is invested in U.S. dollar–denominated, high-quality, short-term fixed income securities. It is not invested in the stock market. The primary objectives of the OSTF investment activities, in priority order, are preservation of principal, liquidity, and yield.

All state agencies and certain public universities participate in the fund. Local governments, such as school districts and counties, and tribal governments have the option to access the fund by participating in the Local Government Investment Pool. Roughly 1,000 local governments participate.

Interest Rates Paid on Account Balances in the OSTF

Interest is accrued on interest bearing accounts based on the end of day balance of the account times the rate for that day, divided by the number of days in the year. Accrued interest is distributed on the last day of the month and includes interest accrued for the last day of the month.

Time Certificates of Deposit Program

One way that Treasury helps to invest in Oregon communities is through voluntary Time Certificate of Deposits, also known as TCDs. Through the OSTF, Treasury will buy short term TCDs from qualified institutions that make orders. The funds can then be used by the requesting institutions to make more loans within their communities. Treasury has a goal of making at least $200 million available through the program. 

The program is authorized under ORS 295.081. The transaction occurs each quarter on the “order date.” On that order date, Treasury will identify the rates and durations for CDs, which can be for 3-, 6- or 12-month maturities.
