The treasurer provides for the safe and efficient operation of state government through effective banking, investment, and cash management.

The persons having the highest number of votes for the office of the state treasurer shall be declared duly elected.

The Constitution of Oklahoma places no limit to the number of terms a candidate may serve in succession or in total.

To earn additional revenue for Oklahoma, the state treasurer invests money which is not immediately needed to fund government operations.

The office provides banking and investment services for state agencies, reuniting individuals and businesses with their unclaimed property, and promoting economic development Statewide.

However, Oklahoma's history of electing governors and treasurers of the same party has often led to positive working relationships between the two offices.

Only once in recent history has a state treasurer also served as the governor's budget advisor; Governor Brad Henry appointed Miller's predecessor Scott Meacham as his secretary of finance and revenue, giving Meacham supervision over all finance agencies of the State government.
