In a letter filed today with the Securities and Exchange Commission (SEC) the FIA Principal Traders Group (FIA PTG) supported the proposed move from T+2 to T+1 settlement. FIA PTG said the overall reduction of risk in the system resulting from shortening the settlement cycle to T+1 justifies the effort and costs associated with the initiative. However, they went on to say that shortening the settlement cycle further to T+0 would unnecessarily increase systemic risk.
