Whether or not a CD is negotiable is typically a function of how the CD was acquired, rather than whether it is standard or jumbo in size. CDs opened directly with a bank or credit union are held in the depositor's name and are rarely negotiable. They can be liquidated only according to the bank's policy on early withdrawals and the associated penalty. Alternatively, CDs can be opened through brokerage firms, and these certificates, called brokered CDs, are bought and sold on a secondary market. Instead of going to a bank to open one of these certificates, you do so via your account at a brokerage house (e.g., Vanguard, Fidelity, etc.), and multiple CDs from more than one institution can be held in a single brokerage account, making the process of tracking and managing more than one certificate much simpler. The trade-off for this convenience is two-fold. First, the rates of return on brokered CDs are usually less competitive than direct bank CDs. Second, if you want to withdraw your funds from a brokered CD, you cannot simply liquidate it and pay the bank a penalty. Instead, you must put the CD up for sale on the secondary market operated by the brokerage, and the price you receive (which depends on the current rate environment) is far from predictable.
