As competition grew, a transaction-system to handle the transactions in IMM was required. The CME and Reuters Holdings introduced Post Market Trade (PMT) for worldwide electronic automated transactions. The system became the single clearing entity to link the major financial centres like Tokyo and London.

Now, PMT is called Globex, which deals not only in clearing but also in electronic trading for traders around the world. In 1976, US T-bills began trading on the IMM. T-bill futures were introduced in April 1986 that was approved by the Commodities Futures Trading Commission.
