The TSP has issued rules making final as of tomorrow (May 1) a policy generally allowing investors to make only two interfund transfers per month, with a third allowed only to move money into the government securities fund—the TSP’s most conservative fund and one in which investors often park their money while preparing to take out a loan or withdrawal. The notice in the April 24 Federal Register repeated the TSP’s oft-stated reasoning for the change: that a small minority of investors are abusing the policy that allows transfers every business day, adding overhead costs that under the TSP’s structure must be shared by all investors. The policy change does not affect decisions regarding ongoing investments, only money already in accounts.
