The Supreme Position of the U.S. Dollar in New Financial Innovations and Instruments
Junji Tokunaga and Gerald Epstein
Importantly, the supreme position of U.S. dollar in new financial innovations and instruments contributed to halting the declining trend of the dollar as a debt-financing currency and reversed the falling role of the dollar in the 2000s.
First of all, an unprecedented increase in U.S. dollar-denominated asset-backed security (ABS) issuance contributed to the revival of the dollar as a debt-financing currency in the 2000s. Currency shares in ABS and non-convertible bond issuance is provided in Figure 7. The share of U.S. dollar in ABS issuance rose from around 65 percent in 1999 to 75-80 percent on the eve of the financial crisis (as shown in Panel B), while the share of euro increased gradually from around 15% to in 1999 to about 20 percent, respectively (as demonstrated in Panel A).
ECB  explains some factors underlying the decision on the currency denomination of ABS issuance as follows: Firstly, the origin of the underlying collateral, as well as investors’ preferences, seems to be an important factor in the decision on the currency denomination of ABS issuance. In fact, substantial amounts of collateral are located in the U.S. Secondly, the development of new financial innovations and instruments plays an important role in influencing a currency’s prominence in global financial markets. In particular, the securitization function can transform risky, long-term loans (subprime mortgage in the U.S., for example) into seemingly credit-risk free, dollar-denominated long-term debt securities such as ABS.
In addition, the dominant position of the dollar in credit default swaps (CDSs) is thought to support the prominence of U.S. dollar-denominated ABS issues. A CDS is a swap contract in which the buyer of the CDS protection makes a series of payments to the seller of it, and receives a payoff if a credit instrument goes into default. CDSs function as a hedging credit risk associated with the underlying assets. LCFIs bought large amounts of CDSs on ABS and CDO written by insurance companies. Table 1 demonstrates currency breakdown of credit derivatives from May 1 to July, 2010. While the percent of the dollar in total transactions amounted to 63%, its share reached 57% in total notional size.
Secondly, the rapid growth of U.S. dollar-denominated safe, short-term and liquid assets facilitated the revival of the dollar as debt-financing currency in the 2000s. Table 2 reports total asset-backed commercial paper (ABCP) outstanding by the location of the sponsor and the funding currency as of January 2007. In total, $714 billion out of $969 billion, or 73.7 percent, was issued in the dollar. Notably, most European banks financed their off-balance vehicles by issuing ABCP denominated in dollars rather than in euro.
Also, there are no official data on the currency denomination in the repo market, which is at the center of the globally integrated wholesale funding process. Table 3 presents liabilities and equity of the domestic economy and amounts held by rest of world as of June 2007. Foreign holdings of Treasuries bonds made up the largest percentage of the amount outstanding (45%), the share of Agency bonds, corporate bonds (non asset-backed), and corporate ABS+ABCP (asset-backed commercial paper) reached 21%, 25%, and 22%, respectively, which were a higher share than total foreign holdings (13%). U.S. treasuries have played the role of “universally accepted collateral,” that is, the asset most widely accepted as collateral in repo markets. Taking the higher share of foreigners holding U.S. private debt securities into account, a broad range of private debt instruments, whose underlying assets are located in the U.S., has been also used for “universally accepted collateral” in the global repo market in the 2000s. It is, therefore, likely that the dollar has played the dominant role as collateral assets in the global repo market.
In summary, most of both long-term (ABS) and short-term debt instruments (ABCP and repos) created by LCFIs in the global shadow banking system were denominated in U.S. dollars. This resulted in the revival of the dollar as a debt-financing currency in the 2000s, despite the persistent decline in currency asymmetry since the second half of the 1980’s. Importantly, the revival of the dollar as a debt-financing currency underpinned by the dominant role of U.S. dollar in new financial innovation and instruments, supported the endogenous finance of the global dollar in the 2000s.
 IMF [2011a] presents a case study that global systemically important financial institutions (G-SIFIs) bought large amounts of credit default swaps (CDSs) on largely subprime mortgage collateralized debt obligations (CDOs) written by AIG Financial Products (AIGFP), which was a London branch of a French incorporated subsidiary (pp.8-13).
