Commercial & Investment Banking: Should This Divorce Be Saved?

The separation between commercial and investment banking has been one of the primary features of the U.S. financial system since the 1930s. Congress is responsible for this separation, having decided that the investment banking activities of the nation's large commercial banks contributed to the widespread bank failures of the Depression. To prevent further failures, it passed legislation in 1933 that created a wall between commercial and investment banking activities and authorized a federal deposit insurance system.

Since the Depression, a number of academic studies have suggested that such investment banking activities did not significantly contribute to massive bank failures. In addition, many now argue that the U.S. commercial banking system would actually be stronger if banking organizations were permitted to affiliate directly with investment banking concerns, a system usually referred to as universal banking. Some even advocate affiliations between banks and commercial or insurance firms. Should the divorce between commercial and investment banking be saved, or is there a good case for reconciliation?

A Common-Law Marriage

Commercial and investment banking have been kept apart for most of America's history. According to Perkins (1971) and others, our post-Civil War banking system was modeled more or less on English banking practices, which featured a sharp division between commercial and investment banking. Investment banking, which involves dealings in stocks and bonds, was considered both risky and unsound for commercial banks that collected savings from the public.

The concurrent development of trust companies, however, blurred this neat distinction. Because of relatively liberal state incorporation laws, many trust companies evolved from administering estates and wills, to soliciting customer deposits and financial planning, and later to distributing, marketing and purchasing corporate equity securities. While some financial analysts of the time noted the potential conflict of interest, others praised the convenience of being able to get all types of banking and investment services under one roof.

Recognizing the advantages that trust companies enjoyed, state-chartered banks lobbied for and won comparable powers. Nationally chartered banks, which were not granted these powers under the National Bank Act of 1864, gained them anyway by setting up separate state-incorporated securities affiliates. On the eve of World World I, state and national banks' move into investment banking was not a major or even a minor public policy issue. That would change in the inter-war period.

The massive sale of bonds to finance WWI brought scores of new players into the securities markets. Banks were expected to help the war effort by lending investors the funds to purchase war bonds on favorable terms; they did so in large numbers by expanding their bond departments or forming new securities affiliates. By 1922, 62 commercial banks were directly engaged in investment banking, and another 10 had launched securities affiliates.

Commercial bank involvement in investment banking continued to grow in the 1920s. A reduction in corporate loan demand, caused by the issuance of long-term corporate debt and equity and large cash flows that eliminated the need for borrowing by many companies, led commercial banks to look elsewhere for profits. Many large urban banks, buoyed by a rising stock market and other factors, chose investment banking to fill that profit void. Between 1927 and 1930, commercial banks' share of the new bond issuance participation market rose from 37 percent to 61 percent. By 1930, commercial banks and their securities affiliates were the principal players in investment banking. Commercial and investment banking had more or less merged into a common-law marriage, without any fanfare but also without a complete official blessing.

1929: Marriage on the Rocks

The stock market crash of 1929, some spectacular bank failures and the advent of the Great Depression cast a bright light on this union. Because many blamed the crash on excessive speculation in the stock market, institutions associated with securities markets, including the securities affiliates of large commercial banks, were deemed guilty by association. Leading the charge against the bank securities affiliates was Senator Carter Glass of Virginia.

Glass was never comfortable with the unofficial union of commercial and investment banking. During the course of several hearings he convened in the early 1930s, bankers were accused, among other things, of making bad loans to their corporate borrowers, then duping other customers into buying securities issued by these firms, with the proceeds going to pay off the loans. Glass became convinced that the mixing of commercial and investment banking caused the catastrophic events of the late 1920s and early 1930s. His solution: split them apart.

Glass' opponents argued that the affiliate system had been instrumental in the strong economic growth of the 1920s and that bank customers had become accustomed to one-stop banking; such arguments, however, largely fell on deaf ears as stock market scandals and bank failures increased. In May of 1933, Glass' bill mandating the legal separation between commercial and investment banking was merged with Representative Henry Steagall's deposit insurance bill, and in June, President Roosevelt signed the Banking Act of 1933 into law, severing most of the ties between commercial and investment banking.

The Divorce Decree

Under the Banking Act of 1933 (or the Glass-Steagall Act, as it is commonly referred to) banks were forbidden from:

  • purchasing securities for their own accounts (Section 16);
  • issuing, underwriting, selling or distributing, at wholesale or retail, or through syndicate participation, stocks, bonds, debentures, notes or other securities, with the exception of certain U.S. and municipal government securities (Section 21);
  • affiliating with a company principally engaged in the activities listed above (Section 20);
  • having interlocking directorships or close employee relationships with a firm principally engaged in securities underwriting or distribution, even if there is no common ownership or corporate affiliation between the commercial bank and the investment company (Section 32).

Over time, federal bank regulators and the courts have eroded some of the official separation by permitting banks to engage, mostly indirectly, in many securities-related activities. For example, both the Federal Reserve and the Office of the Comptroller of the Currency (OCC) permit the banks they regulate to engage in many mutual fund-related activities, including the provision of full service and discount brokerage services and investment advisory services for a fund.

Regarding underwriting, the Federal Reserve has allowed member banks to affiliate (through the bank holding company structure) with securities companies that underwrite commercial paper, mortgage-backed securities and corporate debt and equity securities, among other instruments, so long as these activities contribute less than a small, fixed percentage of the affiliate's revenue. About 36 banking organizations operating in the United States currently have active securities affiliates, dubbed "Section 20 subsidiaries" after the Glass-Steagall provision that proscribes full affiliate relationships (see table).

Twenty-three of the 36 Section 20 affiliates currently active are subsidiaries of U.S.-based bank holding companies. Fourteen of the 23 were granted Section 20 powers between 1987 and 1990, while five are relative newcomers, receiving Section 20 authorization in 1993 or 1994. About one-third of them have been given limited corporate debt and underwriting privileges.

1 All Section 20 subsidiaries are authorized to underwrite and deal in certain municipal revenue bonds, mortgage-related securities, commercial paper and asset-backed securities.

Commercial banks have not been the only winners in this erosion: Investment bankers and securities brokers have been allowed to engage in limited commercial bank activities, such as making loans and offering money market management accounts that are very similar to bank deposits. Such regulatory interpretations have generally been upheld by the courts, including in some cases the U.S. Supreme Court.

The Act's potency has also been diminished by some of its exceptions and exclusions. Sections 16, 20 and 32, for example, apply only to members of the Federal Reserve System, that is, nationally chartered and state member banks; because of these exclusions, state nonmember banks and thrifts are legally free to affiliate with securities firms. The Act also applies only to the domestic activities of U.S. commercial banks; most of the country's large money center banks—ironically, the Act's main targets—have significant securities underwriting and securities brokerage operations outside the United States.

Why Reconcile?

Despite these gains, most banking industry analysts and economists believe the erosion of Glass-Steagall is not enough. For example, though all commercial banks are able to engage in many mutual fund-related activities, most banks must still contract with outside providers to organize or underwrite a mutual fund. Similarly, the revenue cap on certain securities activities conducted by Section 20 subsidiaries forces banking organizations to forego profit opportunities.

Although policymakers have previously debated dismantling Glass-Steagall, support for its repeal has always been effectively countered by opposition from bank competitors and small banks. Lately, however, the tide appears to have shifted in favor of repeal, and many observers believe some version of two current Congressional bills and a Clinton Administration proposal for reform will become law this year (see sidebar). Is the reunion of commercial and investment banking a good idea?

The Case for Reconciliation

The calls for Glass-Steagall repeal usually go hand in hand with a broader appeal for expanded bank powers. Citing U.S. banks' continuing loss of market share to less regulated financial services firms, proponents of repeal argue that banks need to be able to offer new products and services to make up for declining profit margins in their traditional loan and deposit lines of business. Most observers believe that restrictions on U.S. commercial bank activities not only hinder U.S. banks' competitiveness in domestic and global markets but also endanger their safety and soundness by inhibiting diversification of assets.

Only two major industrial nations currently feature a legal separation between commercial and investment banking: the United States and Japan. Other large industrial countries like Germany and Switzerland have universal banking, allowing banks to affiliate with other financial services firms, including insurance, real estate and securities firms.

As money and capital markets become more globalized, proponents of universal banking argue, it will be increasingly difficult for U.S. banks, as currently structured, to compete with large, international, financial conglomerates for corporate and consumer business. They also argue that allowing nonbanking firms to own and affiliate with banks will bring additional capital into the banking industry, bolstering its safety and soundness; higher capital, all else equal, reduces the probability of bank failure and hence losses to the FDIC and to taxpayers.

Increased bank diversification is another benefit to be expected if Glass-Steagall is repealed. One of the leading causes of bank failure is overdependence on one product or geographic region, a recognition that spurred last year's passage of interstate branching legislation. By broadening the range of products that a banking organization can offer, its revenue stream is also broadened, making it less likely that losses in one product area would cause losses for the whole organization. The potential revenue stream would also be enhanced by the cross-marketing of banking and investment products, like deposits and securities or insurance. And product diversification, of course, is decidedly pro-consumer.

Another argument in favor of universal banking is the possibility of increased efficiency in the provision of financial services. Any cost reductions are likely to result from the presence of economies of scale or economies of scope. Economies of scale are said to exist if average costs fall as output increases; economies of scope exist if the cost of joint production of two or more products is less than the costs of separate production. Joint production costs may be lower because inputs like computers and personnel can be shared. If scale or scope economies are present in banking, then policies that would allow banks to become larger or produce additional services would increase efficiency and presumably benefit banks in the form of higher profits and businesses and consumers in the form of lower prices.

The Case for the Status Quo

Critics of universal banking argue that breaking down the wall between commercial and investment banking (or between commercial banking and commerce) will lead to fewer banks and increased concentration and monopoly power in the industry, resulting in less credit extended and higher prices. There is little evidence to support this assertion, however. Despite substantial consolidation in the banking industry through mergers and failures over the last decade and a half—the number of banks has declined from 14,836 in 1980 to 10,358 in 1994—measures of industry concentration have hardly changed.

Studies of the German banking system also indicate no evidence of concentration of power within the financial services industry or monopolization of universal banks over nonbanks. Most economists believe that the threat of entry or competition is enough to deter banks from exercising monopoly power. And when it's not, antitrust laws can be invoked to alleviate the problem.

Potential conflicts of interest and abusive practices are other reasons for maintaining the separation. These are the same charges that Carter Glass and his allies made against bank securities affiliates in the 1930s. Critics worry, for example, that bank creditors and the FDIC could suffer losses if a bank transferred insured funds to an ailing affiliate. They also cite the potential for abusive practices like"tying," that is, requiring the joint purchase of a number of products. To get a mortgage, for example, a borrower may be forced to purchase homeowners insurance and mortgage life insurance from the same organization.

This argument can also be countered. First, the securities activities of banks in the 1920s and 1930s have largely been vindicated by recent studies. One study, for example, found no evidence that commercial banks of that era dumped low quality securities on the public or that their securities were overpriced. In fact, the authors found that bank affiliates actually underwrote higher quality securities than did investment banks. Second, as proponents of universal banking maintain, appropriate "firewalls" can be constructed to ensure that transactions between banks and nonbank affiliates are done at arm's length.

Opponents of universal banking also argue that the marriage of commercial and investment banking or banking and commerce will destabilize the banking system by blurring the distinction between insured and noninsured activities. They worry that bad news about a bank affiliate or parent company will cause a bank run or that excessive dividend payments from the bank to the parent will jeopardize the bank's financial health.

A final concern is that these larger institutions will be "too big to fail," necessitating an extension of the federal safety net—the deposit insurance system, the payments system and the Federal Reserve's discount window—to nonbanks. As with the conflict of interest concerns, however, most analysts believe that the necessary safeguards are available to contain a severe financial crisis.

Happily Ever After...

Is the union between commercial and investment banking an unholy alliance as many thought in the 1930s? A closer look at the evidence has convinced most policymakers and economists today that the split between the two was a mistake. Permitting banks to diversify into other lines of business, while at the same time building adequate safeguards to ensure that insured deposit funds are not jeopardized, will promote efficiency and stability in the U.S. banking system and more choices for U.S. consumers and businesses. This is one couple that should probably get back together.
