Monetary instruments are stocks, bonds, treasury bills, bank drafts, promissory notes, and money orders, in bearer form or in such other form that title passes on delivery. They also include unsigned traveller's cheques and endorsed cheques.
Monetary instruments are in bearer form when they are blank (when the owner's name does not appear on the instruments) or when they are "payable to the bearer." This means that anybody can bring the monetary instruments to a financial institution to cash them.
