Corporate debt The original speculative grade bonds were bonds that had been investment grade at the time of issue, but the credit rating of the issuer had slipped and the possibility of default increased significantly. These bonds are called "fallen angels". The
investment banker Michael Milken realized that fallen angels had regularly been valued less than what they were worth. His experience with speculative grade bonds started with his investment in these. In the mid-1980s, Milken and other investment bankers at
Drexel Burnham Lambert created a new type of high-yield debt: bonds that were speculative grade from the start, and were used as a financing tool in
leveraged buyouts (LBOs) and
hostile takeovers. In 2005, over 80% of the principal amount of high-yield debt issued by U.S. companies went toward corporate purposes rather than acquisitions or buyouts. In emerging markets, such as China and Vietnam, bonds have become increasingly important as short-term financing options since access to traditional bank credit has been proved to be limited, especially if borrowers are non-state corporates. The corporate bond market has been developing in line with the general trend of capital markets, and the equity market in particular.
Debt repackaging and subprime crisis High-yield bonds can also be repackaged into
collateralized debt obligations (CDO), thereby raising the
credit rating of the senior
tranches above the rating of the original debt. The senior tranches of high-yield CDOs can thus meet the minimum credit rating requirements of pension funds and other institutional investors despite the significant risk in the original high-yield debt. , headquarters of
AXA, first worldwide insurance company. When such CDOs are backed by assets of dubious value, such as
subprime mortgage loans, and lose
market liquidity, the bonds and their derivatives become what is referred to as "toxic debt". Holding such "toxic" assets led to the demise of several
investment banks such as
Lehman Brothers and other financial institutions during the
subprime mortgage crisis of 2007–09 and led the US Treasury to seek congressional appropriations to buy those assets in September 2008 to prevent a systemic crisis of the banks. Such assets represent a serious problem for purchasers because of their complexity. Having been repackaged perhaps several times, it is difficult and time-consuming for
auditors and accountants to determine their true value. As the
recession of 2008–09 hit, their value decreased further as more debtors defaulted, so they represented a rapidly
depreciating asset. Even those assets that might have gone up in value in the long-term depreciated rapidly, quickly becoming "toxic" for the banks that held them.
Toxic assets, by increasing the variance of banks' assets, can turn otherwise healthy institutions into
zombies. Potentially insolvent banks made too few good loans creating a
debt overhang problem. Alternatively, potentially insolvent banks with toxic assets sought out very risky speculative loans to shift risk onto their depositors and other creditors. On 23 March 2009, U.S. Treasury Secretary
Timothy Geithner announced a
Public-Private Investment Partnership (PPIP) to buy toxic assets from banks' balance sheets. The major stock market indices in the United States rallied on the day of the announcement rising by over six percent with the shares of bank stocks leading the way. PPIP has two primary programs. The Legacy Loans Program will attempt to buy residential loans from banks' balance sheets. The
Federal Deposit Insurance Corporation will provide non-recourse loan guarantees for up to 85 percent of the purchase price of legacy loans. Private sector asset managers and the U.S. Treasury will provide the remaining assets. The second program is called the legacy securities program which will buy mortgage backed securities (RMBS) that were originally rated AAA and commercial mortgage-backed securities (CMBS) and asset-backed securities (ABS) which are rated AAA. The funds will come in many instances in equal parts from the U.S. Treasury's
Troubled Asset Relief Program monies, private investors, and from loans from the Federal Reserve's
Term Asset Lending Facility (TALF). The initial size of the Public Private Investment Partnership is projected to be $500 billion. Nobel Prize–winning economist
Paul Krugman has been very critical of this program arguing the non-recourse loans lead to a hidden subsidy that will be split by asset managers, banks' shareholders and creditors. Banking analyst
Meredith Whitney argues that banks will not sell bad assets at fair market values because they are reluctant to take asset write downs. Removing toxic assets would also reduce the volatility of banks' stock prices. Because stock is akin to a
call option on a firm's assets, this lost
volatility will hurt the stock price of distressed banks. Therefore, such banks will only sell toxic assets at above market prices. ==EU member state debt crisis==
