United States v. Marine Bancorporation, Inc.
418 U.S. 602, 94 S. Ct. 2856, 1974 U.S. LEXIS 4 (1974)
Rule of Law:
The application of the potential-competition doctrine under Section 7 of the Clayton Act to commercial bank mergers must account for extensive federal and state regulatory barriers to entry, which can significantly reduce the likelihood of alternative procompetitive entry methods or a "perceived potential entrant" effect.
Facts:
- National Bank of Commerce (NBC), headquartered in Seattle, Washington, was the second-largest banking organization in the state, operating 107 branch offices but none in the Spokane metropolitan area.
- Washington Trust Bank (WTB) was a state bank headquartered in Spokane, Washington, with seven branch offices in the Spokane metropolitan area and held 18.6% of total deposits in that market.
- NBC and WTB were not direct competitors in the Spokane metropolitan area or any other significant market.
- The Spokane metropolitan area's commercial banking market was highly concentrated, with three banking organizations (including WTB) controlling approximately 92% of total deposits.
- Washington state law prohibited de novo branching into cities or towns where other banks already operated, restricted branching from an acquired bank, and forbade multibank holding companies.
- NBC had a longstanding interest in entering the Spokane market.
- In February 1971, Marine Bancorporation (NBC's parent), NBC, and WTB agreed to a merger where WTB would be absorbed into NBC, and NBC would operate WTB's eight offices as its branches.
Procedural Posture:
- In March 1971, NBC and WTB applied to the Comptroller of the Currency for approval of their proposed merger under the Bank Merger Act of 1966.
- The Attorney General, Federal Deposit Insurance Corporation, and Board of Governors of the Federal Reserve System all submitted negative reports on the competitive effects of the merger.
- On September 24, 1971, the Comptroller of the Currency approved the merger, concluding that state law precluded NBC from de novo entry into Spokane and that the merger would benefit Spokane bank customers.
- The United States commenced a civil antitrust action in the U.S. District Court for the Western District of Washington, challenging the merger's legality under Section 7 of the Clayton Act, which automatically stayed the merger.
- The Comptroller of the Currency intervened as a party defendant in support of the merger.
- Prior to trial, the United States dropped allegations of actual competition, proceeding exclusively on the potential-competition doctrine.
- The District Court ruled for the defendants, finding no reasonable probability that NBC would enter the Spokane market in the foreseeable future absent the challenged merger, due to legal and economic barriers, and dismissed the Government's complaint.
- The Government brought a direct appeal to the Supreme Court.

Issue:
Does a proposed merger between a large bank (NBC) and a medium-sized bank (WTB) in a concentrated market violate Section 7 of the Clayton Act under the potential-competition doctrine, when stringent state regulatory barriers effectively prevent the acquiring bank from entering the market de novo or expanding significantly after a "foothold" acquisition?
Opinions:
Majority - Mr. Justice Powell
No, the proposed merger does not violate Section 7 of the Clayton Act under the potential-competition doctrine because extensive state banking regulations severely restrict alternative, procompetitive means of entry for the acquiring bank. The Court affirmed that Section 7 principles apply to commercial banking but emphasized the unique regulatory landscape. It found that Washington's stringent laws (prohibiting de novo branching, branching from acquired offices, and multibank holding companies) made it highly improbable that NBC could enter the Spokane market in a way that would significantly deconcentrate it (e.g., through sponsoring a new bank or a small "foothold" acquisition). Even if such entry were legally possible, the inability to branch afterwards would "freeze" NBC's presence at an insignificant level, offering little long-term competitive benefit. Consequently, the Court concluded that NBC's pre-merger presence on the fringe of the Spokane market did not exert a "meaningful procompetitive influence" (the "wings effect") because rational Spokane bankers would be aware of these insurmountable regulatory barriers. The Court also dismissed the Government's claim that WTB itself had a potential for growth outside Spokane as mere speculation.
Dissenting - Mr. Justice White
Yes, the proposed merger should be prohibited under Section 7 of the Clayton Act because it eliminates a significant potential competitor in the highly concentrated Spokane market. Justice White agreed that NBC had the resources and desire to enter Spokane and that the Spokane market was concentrated. He argued that alternative entry methods, such as acquiring a small existing bank (toehold) or sponsoring a new bank, were feasible despite the state's branching restrictions, citing past instances where regulatory consent for such actions was obtained. He rejected the majority's "per se view" that a bank could not be a substantial competitive influence without unlimited branching, pointing to the successful growth of small Spokane banks as evidence. Justice White contended that NBC, as a major Seattle bank, would have been an effective competitor, particularly in lending, even with limited offices, and that its perceived presence would have exerted a procompetitive "waiting-in-the-wings" influence. He criticized the majority for significantly raising the burden of proof in potential competition cases, thereby undermining the intent of Section 7 to prevent market concentration, especially in the crucial banking sector.
Analysis:
This case is pivotal for clarifying the application of the potential-competition doctrine in regulated industries, particularly banking. The Supreme Court underscored that unique industry-specific regulatory barriers are central to determining the feasibility and likelihood of alternative entry methods and the "perceived potential entrant" effect. By giving significant weight to state-level restrictions on branching and holding companies, the decision created a higher hurdle for the government to block bank mergers on potential competition grounds in states with restrictive banking laws. It implicitly acknowledges that while banking markets may appear structurally concentrated, actual competitive dynamics can be constrained by regulatory realities, shifting the focus from purely theoretical market structures to practical entry feasibility.
