Are the Banks Taking Off their Market-Making Hat to Become Brokers?

“A broker is foolish if he offers a price when there is nothing on the offer side good to the guy on the phone who wants to buy. We may have an offering, but we say none.” –Marcy Stigum


Before the slow but eventual repeal of Glass-Steagall in 1999, U.S. commercial banks were institutions whose mission was to accept deposits, make loans, and choose trade-exempt securities. In other words, banks were Cecchetti’s “Financial intermediaries.” The repeal of Glass-Steagall allowed banks to enter the arena so long as they become financial holding companies. More precisely, the Act permitted banks, securities firms, and insurance companies to affiliate with investment bankers.Investment banks, also called non-bank dealers, were allowed to use their balance sheets to trade and underwrite both exempt and non-exempt securities and make the market in both the capital market and the money market instruments. Becoming a dealer brought significant changes to the industry. Unlike traditional banks, investment banks, or merchant banks, as the British call it, can cover activities that require considerably less capital. Second, the profit comes from quoting different bid-ask prices and underwriting new securities, rather than earning fees. 

However, the post-COVID-19 crisis has accelerated an existing trend in the banking industry. Recent transactions highlight a shift in power balance away from the investment banking arm and market-making operations. In the primary markets, banks are expanding their brokerage role to earn fees. In the secondary market, banks have started to transform their businesses and diversify away from market-making activities into fee-based brokerages such as cash management, credit cards, and retail savings accounts. Two of the underlying reasons behind this shift are “balance sheet constraints” and declining credit costs that reduced banks’ profit as dealers and improved their fee-based businesses. From the “Money View” perspective, this shift in the bank’s activities away from market-making towards brokerage has repercussions. First, it adversely affects the state of “liquidity.” Second, it creates a less democratic financial market as it excludes smaller agents from benefiting from the financial market. Finally, it disrupts payment flows, given the credit character of the payments system.

When a banker acts as a broker, its income depends on fee-based businesses such as monthly account fees and fees for late credit card payments, unauthorized overdrafts, mergers, and issuing IPOs. These fees are independent of the level of the interest rate. A broker puts together potential buyers and sellers from his sheet, much in the way that real estate brokers do with their listing sheets and client listings. Brokers keep lists of the prices bid by potential buyers and offered by potential sellers, and they look for matches. Goldman, Merrill, and Lehman, all big dealers in commercial paper, wear their agent hat almost all the time when they sell commercial paper. Dealers, by contrast, take positions themselves by expanding their balance sheets. They earn the spread between bid-ask prices (or interest rates). When a bank puts on its hat as a dealer (principal), that means the dealer is buying for and selling from its position. Put another way, in a trade, the dealer is the customer’s counterparty, not its agent.

Moving towards brokerage activity has adverse effects on liquidity. Banks are maintaining their dealer role in the primary market while abandoning the secondary market. In the primary market, part of the banks’ role as market makers involves underwriting new issues. In this market, dealers act as a one-sided dealer. As the bank only sells the newly issued securities, she does not provide liquidity. In the secondary market, however, banks act as two-sided dealers and supply liquidity. Dealer banks supply funding liquidity in the short-term money market and the market liquidity in the long-term capital market. The mission is to earn spreads by constantly quoting bids and offers at which they are willing to buy and sell. Some of these quotes are to other dealers. In many sectors of the money market, there is an inside market among dealers. 

The money market, as opposed to the bond market, is a wholesale market for high-quality, short-term debt instruments, or IOUs. In the money market, dealing banks make markets in many money market instruments. Money market instruments are credit elements that lend elasticity to the payment system. Deficit agents, who do not have adequate cash at the moment, have to borrow from the money market to make the payment. Money market dealers expand the elasticity daily and enable the deficit agents to make payments to surplus agents. Given the credit element in the payment, it is not stretching the truth to say that these short-term credit instruments, not the reserves, are the actual ultimate means of payment. Money market dealers resolve the problem of managing payments by enabling deficit agents to make payments before they receive payments.

Further, when dealers trade, they usually do not even know who their counterparty is. However, if banks become brokers, they need to “fine-tune” quotes because it matters who is selling and buying. Brokers prefer to trade with big investors and reduce their ties with smaller businesses. This is what Stigum called “line problems.” She explains that if, for example, Citi London offered to sell 6-month money at the bid rate quoted by a broker and the bidding bank then told the broker she was off and had forgotten to call, the broker would be committed to completing her bid by finding Citi a buyer at that price or by selling Citi’s money at a lower rate and paying a difference equal to the dollar amount Citi would lose by selling at that rate. Since brokers operate on thin margins, a broker wouldn’t be around long if she often got “stuffed.” Good brokers take care to avoid errors by choosing their counterparties carefully.

After the COVID-19 pandemic, falling interest rates, the lower overall demand for credit, and regulatory requirements that limit the use of balance sheets have reduced banks’ profits as dealers. In the meantime, the banks’ fee-based businesses that include credit cards late-fees, public offerings, and mergers have become more attractive. The point to emphasize here is that the brokerage business does not include providing liquidity and making the market. On the other hand, dealer banks generate revenues by supplying funding and market liquidities in the money and capital markets. Further, brokers tend to only trade with large corporations, while dealers’ decisions to supply liquidity usually do not depend on who their counterparty is. Finally, the payment system is much closer to an ideal credit payment system than an ideal money payment system. In this system, the liquidity of money market instruments is the key to a well-functioning payment system. Modern banks may wear one of two hats, agent (broker) or principal (dealers), in dealing with financial market instruments. The problem is that only one of these hats allows banks to make the market, facilitate the payment system, and democratize access to the credit market.
