Establishes the Missouri Savings Account Fund within the state treasury, to be invested by the treasurer with interest credited to the fund.

Requires the commissioner of administration to transfer 2% of total general revenue appropriations to the fund annually beginning in fiscal year 2012, excluding debt service, fund appropriations, and supplemental appropriations.

Allows the general assembly to appropriate funds from the account if actual net general revenue collections are less than 3% greater than the prior fiscal year, up to one-third of the fund balance.

Permits appropriations from the fund during legislative sessions when estimated general revenue is expected to decline or when the governor reduces agency expenditures, with withdrawals limited to one-third of the fund balance.

Requires excess balances exceeding one-third of actual net general revenue collections to be transferred back to the general revenue fund, unless the excess results from direct legislative appropriations.
