During the 2008 financial crisis, the American public began to hone in on the practices of investment banks as epitomizing greed on Wall Street. As reports of bank bailouts and home foreclosures began to trickle out, the veil of mystery surrounding the activities of investment banks was slowly lifted.

A growing number of investment banks, which were initially formed as small partnerships to provide strategic corporate advice and financing services, had evolved into financial “supermarkets” that were continuously implementing new strategies in order to develop additional revenue streams.

The result? “Financialization” of the American economy.

In 1980, the financial services industry accounted for just 4.9% of US GDP compared to 7.9% in 2007. Over that same time period, the ratio of total financial assets to GDP in the United States more than doubled from five to ten. Main drivers of growth include increasing asset management fees, expansion of household credit, and development of the “shadow-banking” system (Harvard Business School).

Historically, the main purpose of a bank was to match savers with borrowers. Banks served as financial intermediaries, paying interest on deposits while also making loans to businesses and consumers. The rise of computer technology in addition to increasing competition on Wall Street has forced financial services firms to innovate at a wildly fast pace to engineer new financial products.

The transformation of traditional financial services firms into large, diversified financial “supermarkets” is closely related to the history of government regulation. After the stock market crash of 1929, the Glass-Steagall Act was implemented to reduce systemic risk by forcing the separation of commercial banks from securities firms (Liquidated: An ethnography of Wall Street).

Well-known financial institutions such as J.P. Morgan were subsequently forced to spin off their investment banking units (i.e. Morgan Stanley) in order to comply (Booms and Busts).

Beginning in the 1980s and continuing through the 1990s, however, many of these regulations were phased out and commercial banks began to again merge feverishly with securities firms to provide a full suite of financial services to their clients.

One of the largest growth areas for these new financial mega firms became asset management.

Asset Management

In recent years, there has been a push to transfer assets to professional money managers who charge a flat percentage fee to actively manage investments on behalf of a client.

According to data from the Flow of Funds Accounts of the United States, professional managers managed 53% of household equity portfolios in 2007, compared with only 25% in 1980 (Harvard Business School).

As individuals and institutions have allocated an increasingly larger proportion of their assets to managers, overall fee income in the space has risen. In addition, the growing popularity of alternative investment funds (private equity, hedge funds, venture capital, etc.), which typically charge much higher fees than traditional mutual funds, has caused management fees to hit all-time highs.

Some have said that benefits of having more capital allocated to asset management firms include increased stock market participation, enhanced liquidity, and more efficient markets. Others, however, feel that the growth of the asset management industry has led many to overpay for active asset management services.

In addition, some claim that high wages and fees not only lure top talent away from arguably more socially valuable careers, but can also contribute to rising income disparities.

Household Credit

Another area of growth has been the rise in household credit in the form of mortgage debt. Mortgage backed securities (MBS), an innovative financial product developed by investment banks, have greatly increased the amount of capital available to borrowers wishing to purchase a home.

By packaging or “securitizing” large amounts of mortgages into one security, investment banks have been able to tap into a much larger pool of potential investors for home loans.

Although proponents of securitization have argued that innovative financial products such as mortgage-backed securities have enhanced liquidity in the marketplace, others have said that the demand for these products led to the lenient lending practices that resulted in the 2007 subprime mortgage crisis.

Shadow Banking

The development of the “shadow banking” system has also fueled the industry’s growth. Shadow banking has been defined as banking “without access to central bank liquidity or public sector credit guarantees.”

Shadow banks such as hedge funds, investment banks, and structured investment vehicles have come to provide traditional banking services (i.e. originating loans) without having to comply with the same regulations as depository banks.

The spectacular growth of the financial services industry has generated both positive and negative consequences for society.

During the 2008 financial crisis, many Americans became aware for the first time of the increasing influence that Wall Street firms had over normal financial activities like taking out a mortgage. After the crisis, the government enacted the Dodd-Frank Act to bring substantial changes to financial regulation in the US. Despite this, the financial services sector has continued to grow.

The growing power and influence of financial services firms has certainly increased market participation and liquidity, but must be closely monitored for potential risks that could lead to future market meltdowns.
