MNPI (Material Non-Public Information)
Significant company or market information held by specific individuals before public disclosure. Trading on it is strictly prohibited as insider trading, and the entire DCM process is designed around controlling this information.
What Is MNPI?
MNPI (Material Non-Public Information) exists when two conditions are simultaneously met: (1) Material — information that a reasonable investor would consider significant for an investment decision: pre-earnings net income figures, undisclosed M&A plans, new bond issuance plans. (2) Non-Public — information not yet disclosed to the market.
In DCM contexts, MNPI includes planned bond sizes, coupon levels, and issuer financial details before announcement. DCM bankers always handle MNPI during deal execution — this is the fundamental reason the Chinese Wall exists.
Regulatory framework: U.S. SEC Rule 10b-5, EU MAR Articles 7–10, and Korea's Capital Market Act Article 174 all prohibit trading on MNPI.
Managing MNPI During a DCM Deal
During a DCM deal, MNPI management follows very specific procedures. The MNPI clock starts the moment initial discussions begin between issuer and IB.
Deal team members are described as being "inside the syndicate wall" — a wall list of authorized personnel is created and managed. S&T desks are in principle excluded. Once the deal is announced (made public), the information is no longer MNPI.
Complexity arises in "market sounding" — the pre-deal process of gauging investor interest requires sharing some information, making recipients MNPI holders. EU MAR requires receiving investors to acknowledge that they are receiving MNPI in such cases.
