For accounts contracted by the triparty agreement and carried by IBLLC, the account has two segments: securities segment and commodities segment. The regulation of securities and commodities products and brokers in the U.S. is administered by two distinct federal agencies, the Securities and Exchange Commission (SEC) for securities including stocks, ETFs, bonds, options and mutual funds and the Commodities Futures Trading Commission (CFTC) for commodities including futures and options on futures. Please see Comparison of U.S. Segregation Models for more details. Positions in both segments of your account will contribute towards your NAV in respective currency, however, the interest is payable only on the uninvested cash in the securities segment of your account and is not payable on cash held in the commodities segment of your account. You can sweep excess funds from your commodities segment into your securities segment and vice versa each time as you deem it appropriate or set-up an auto-sweep.
For the avoidance of doubt, accounts carried by Interactive Brokers (U.K.) Limited, for example Stocks and Shares (Adult) ISA and Stocks and Shares (Junior) ISA, do not have a commodity segment.
