A few months later, CSFP obtained the approval of New York State banking regulators, so it could officially do business in New York. CSFP did four deals on its first day in New York, too, all of them clearly authorized.

In the United States, the bank's AAA rating was especially important and was the first item CSFP mentioned in the press release it sent out when it opened in New York.

With this top credit rating, Allen Wheat could modify Bankers Trust's clever practices to generate even greater profits. The financial-market innovations that began in 1987 were about to take a few more twists and turns.
Credit ratings were central to the changes, although few financial-market participants understood why at the time. A decade later, credit ratings would be even more important, and would play a central role in the collapse of several companies, including Enron. A few years after, credit rating agencies would be at the center of a global financial meltdown.
The two most prominent credit-rating agencies were Moody's Investors Services and Standard & Poor's Corp., known as S&P. Moody's had been
in the business since 1909, when John Moody began publishing ratings of railroad bonds. S&P followed soon thereafter, and Fitch Investors Serviceâa distant third to Moody's and S&Pâbegan rating bonds in 1924.
The agencies labored in obscurity until 1973, when regulators began tying legal rules to ratings. Because only Moody's, S&P, and Fitch were approved for regulatory purposes, those three agencies had a monopoly lock on the market.
18
Not surprisingly, it was a profitable business. Nearly every company with publicly traded bonds paid the rating agencies directly for the ratings. The typical cost of a rating ranged from $30,000 to $100,000. With thousands of companies needing ratings, business boomed. The legendary investor Warren Buffett invested in Moody's and touted its franchise. By 2002, Moody's would be worth more than Bear Stearns, a prominent investment bank.
As commentator Thomas Friedman put it in 1996, “There are two superpowers in the world today in my opinion. There's the United States and there's Moody's bond rating service. The United States can destroy you by dropping bombs, and Moody's can destroy you by downgrading your bonds. And believe me, it's not clear sometimes who's more powerful.”

Why were credit ratings so important? Again, the explanation related to legal rules. Since 1973, regulators had passed dozens of laws that depended on credit ratings, ranging from AAA to D, with BBB being the all-important
investment-grade
dividing line. By the time Allen Wheat arrived at First Boston, just about every major financial business was limited in some way based on these ratings.
In simple terms, a better rating meant better regulatory treatment. For example, certain mutual funds couldn't buy bonds rated below investment grade. Insurance companies had to set aside more capital for lower-rated bonds. Federal loan guarantees required a high rating. And so on.
During the 1980s, no one understood and profited from credit ratings more than Michael Milken and his investment bank, Drexel Burnham Lambert. When Milken was in business school (also at Wharton), he had noticed that bonds rated below the investment-grade level of BBBânow known as
junk bonds
âwere undervalued relative to higher-rated bonds. The prices of bonds dropped sharply when the credit-rating agencies downgraded them to a level below BBB.
Building on work by previous scholars,
20
Milken concluded that by buying a portfolio of bonds rated below investment grade, an investor could increase returns without increasing risk. Even though a portfolio of sub-investment-grade bonds might include a few companies that defaulted
on their debts, overall the cheap prices of those bonds more than made up for the risks. In other words, the sharp divide between investment-grade bonds and non-investment-grade bonds made no sense. To Milken, junk bonds were like $20 bills lying on the ground, and Drexel began trading them, earning huge profits both from holding sub-investment-grade bonds for its own account and from selling them to other investors who had become believers in “junk.”
Unfortunately, Drexel became involved in various insider-trading schemes and other alleged violations of securities law, and its bond-trading business deteriorated. When Drexel filed for bankruptcy in February 1990âat exactly the same time Allen Wheat joined First Bostonâa baton was passed. Drexel's collapse made credit ratings even more important, and it left a gaping hole in the market for sub-investment-grade bonds.
Like Bankers Trust, Drexel had been active in swaps. Now, banksâand their regulatorsâwere worried about whether Drexel would default on payments owed on its swaps. Regulators and market participants began focusing more on the credit ratings of counterparties in the swap market. And the more they focused on credit ratings, the more important the ratings became.

y combining CSFP's AAA credit rating with the complex deals developed by Bankers Trust, Allen Wheat could create new products and sell them in previously untapped markets. CSFP designed the instruments, but they often were sold through First Boston, which had a more established and better-known sales force than Bankers Trust.
Allen Wheat's marketing pitches were transparently directed at Bankers Trust's derivatives business. One glossy brochure stated, “We solve problems for clients rather than push products on them. In fact, Credit Suisse FP's success can best be understood by focusing on this single underlying theme.”
The pitches worked. CSFP earned numerous awards during this time, including “Swap House of the Year,” “Options House of the Year,” and “Best Derivatives House.” Wheat hired more people in 1991, and took over a floor of First Boston's Park Avenue Plaza glass tower. CSFP developed new trades, which “solved problems” for clients, enabling them to make financial bets or hedge risks in increasingly sophisticated ways.
There were two major innovations at First Boston during the early 1990s. One involved
structured notes
âessentially, highly rated bonds
whose payments were linked to the same types of formulas Bankers Trust had used in its complex swaps with Gibson Greetings and Procter & Gamble (plus a few new formulas CSFP invented). The other innovation related to
structured finance
âa class of deals in which financial assets were repackaged to obtain higher credit ratings. Within a decade, structured finance would become a trillion-dollar industry, ranging from legitimate deals that enabled institutions to transfer risk more efficiently, to more dubious transactions (including those later involved in the collapse of Enron and the 2008 crisis).
First, CSFP began issuing and selling structured notes. Unlike a typical bond, which has a series of standard coupon payments and then a fixed principal repayment, a structured note's returns might vary wildly, based on different variables. In other words, the bondâor noteâwas structured so that its payouts were based on any conceivable financial instrument or index. One structured note was even linked to the number of victories by the Utah Jazz, a professional basketball team,
21
although more typical variables were interest rates or currencies. As Richard Deitz, head of structured fixed income at CSFP, put it, “The types of structures we can come up with are infinite.”
22
For example, the first page of CSFP's presentation to a new-associate training program in the early 1990s featured a structured note with a colossal 21 percent coupon and principal redemption leveraged twenty times. These numbers dwarfed those in the Gibson and P&G swaps, and the trades were even more complicated. Lest any new employees feel they could create pricing models for these trades on their own, the last page of CSFP's presentation stressed that it was “necessary to exercise a great deal of care in modeling random yield curve movements” in valuing the trades. The message: don't try this one on your own.
Given Allen Wheat's background in Asia, it was natural for CSFP to focus on structured notes linked to variables in Asian markets. For example, the bank sold huge numbers of what it called Thai Baht Basket-Linked Notes. The idea behind these notes was that the currency of Thailand, called the baht, had been fluctuating in a very narrow band; investors could profit by betting the baht would remain stable.
Although the central bank of Thailand would not admit to buying and selling baht to keep its value within a particular range, the traders at CSFP had determined that a
proxy basket
of three other currencies closely tracked how the central bank of Thailand managed its own currency. Specifically, they said a basket of 84 percent U.S. dollars, 10.15 percent
Japanese yen, and 5.85 percent Swiss francs had moved within a 3 percent range of the Thai baht's actual movements since 1986.
They then created a trade based on the proxy basket. Credit Suisse's New York branch issued the notes, which paid an attractive fixed coupon of 11.25 percent, more than triple the rate the bank typically would pay.
In return for the big coupon, investors took on the risk that Credit Suisse would not repay the full principal amount. Instead of a fixed principal repaymentâas was typical for standard notesâthe principal amount was linked to a formula based on the Thai baht; specifically, on the difference between the value of CSFP's proxy basket at the time the investor bought the bond and the value at maturity (typically, one year later).
In other words, if the Thai baht went down relative to the proxy basket, the investor would lose money. If the baht stayed in its historical range, the investor would earn huge returns. According to CSFP's research, this structured note had earned an average return of 15 percent since 1986, with the worst return being more than 9 percent. These returns were fantastic, given that most bond investors were earning less than half of that.
Still, the notes were peculiar. Why would investors buy a structured noteâand pay a substantial fee to CSFPâinstead of just borrowing to invest in Thailand directly? After all, an investor buying a Thai-baht-linked note was making precisely the same bet as an investor simply borrowing money to invest in Thailand. (Either way, the investment did well if the Thai baht remained steady and lost money if the baht devalued.) Why the fancy, AAA-rated, proxy-basket package?
The answerâagainârelated to legal rules and credit ratings. Just as Japanese insurers couldn't buy stocks, many investors were prohibited by law from investing in Thailand, where even government bonds had a low credit rating. Thailand was a risky place, and U.S. regulators had adopted rules that prevented many money managers from investing there. According to these rules, pension funds (to give but one example) weren't supposed to be speculating on the baht.
But even if a fund manager couldn't buy Thai-denominated investments, he
could
buy a note issued by a AAA-rated bank. What was wrong with a one-year note issued by Credit Suisse? It was a perfectly legal investment, and it would look safe to a regulator, a shareholder, or even a boss, who hopefully would not see the fine print describing how principal redemption was linked to the Thai-baht proxy basket. Thus, CSFP's
Thai Baht Basket-Linked Notes allowed regulated U.S. investors to play in Thailand, just as Bankers Trust's equity derivatives had allowed Japanese insurers to play in their own markets.
With trades like this one, Allen Wheat's optimism about CSFP was justified. The fees were comparable to those Bankers Trust charged for complex swaps. Credit Suisse's New York branch set up a borrowing programâcalled a
medium-term note facility
âto use in issuing these notes. Setting up the facility was like putting securities on the shelf. CSFP could then
take down
structured-note issues when it wanted, just as Bankers Trust had taken down its private placements.
How optimistic was Wheat? The size of the medium-term note facility for the Thai-basket notesâthe maximum dollar value of notes that could be issuedâwas $1.5 billion. As long as the Thai baht remained steady, both CSFP and its investors would get rich, and no one else would need to know exactly how they had done it.
The idea of structured notes quietly spread throughout Wall Street during 1990. Twenty billion dollars' worth were sold in 1991, $30 billion the next year, and $50 billion the next.
23
By the end of 1993, every major bank sold structured notes. They were the rage among large institutional investors, and one of the hottest products among corporate and government treasurers.
Who bought these notes? The better question was, who
didn't
buy them? The list included major mutual funds, insurance companies, pension funds, and corporations. Many were less sophisticated than Gibson and P&G. State and local governmentsâeven some school districtsâbought the notes. One of the biggest buyers was the elderly treasurer of otherwise-conservative Orange County, California. The most common structured notes resembled the Bankers Trust swaps; essentially, they were hidden bets that interest rates would stay low.
Investment banks soon found thatâwith their meager, single-A credit ratingâthey could not compete with AAA-rated CSFP for structured note issues, or for related swaps. To get a higher rating, they set up derivatives subsidiaries with their own capital. In a typical deal, a bank created a subsidiary and gave it several hundred million dollars of seed capital. Then the subsidiary agreed to strict limits on what it was permitted to do. A bank promised not to do business on behalf of the subsidiary, or to intervene in its transactions. With these protections, the credit-rating agencies agreed to give subsidiaries much higher ratings than their parent banks, typically the highest rating of AAA. As business shifted to these special-purpose
subsidiaries, credit-rating agencies became even more important. One Merrill Lynch employee remarked, “We can't blow our noses without getting approval from them.”
