Structured investment vehicle
Encyclopedia
A structured investment vehicle (SIV) was an operating finance company established to earn a spread between its assets and liabilities like a traditional bank. The strategy of SIVs was to borrow money by issuing short-term securities, such as commercial paper and medium term notes and public bonds at low interest rates and then lend that money by buying longer term securities at higher interest rates, with the difference in rates going to investors as profit. Long term assets could include, among other things, residential mortgage backed securities (RMBS), auto loans, student loans, credit cards securitisations, and bank and corporate bonds. Because of this structure, SIVs were considered to be part of the shadow banking system

. SIVs had an open-ended (or evergreen) structure; they planned to stay in business indefinitely by buying new assets as the old ones matured, much like a bank. The SIV manager was allowed to exchange investments without providing investors asset by asset transparency, instead providing monthly portfolio reports. At their peak in July 2007, SIVs had asset under management in excess of $ 400 billion.

As of October 2008, no SIVs remain.

Overview

A SIV may be thought of as a very simple high quality, virtual bank. Instead of gathering deposits from the public, it borrows cash from the money market by selling short maturity (often less than a year) instruments called commercial paper
Commercial paper

 (CP), medium term notes (MTNs) and public bonds to professional investors. SIVs had the highest ratings of AAA/Aaa enabling them to borrow at interest rates close to the LIBOR, the rate at which banks lend to each other. The gathered funds are then used to purchase long term (longer than a year) bonds

History

In 1988 and 1989, two London bankers, Nicholas Sossidis and Stephen Partridge-Hicks launched the first two SIVs for Citigroup, called Alpha Finance Corp. and Beta Finance Corp. In 1993, Sossidis and Partridge-Hicks left Citigroup to form their own SIV management firm, Gordian Knot, located in the ritzy Mayfair district in London. "Alpha Finance was created in response to volatility in the capital markets at the time. Investors wanted a highly-rated vehicle that would yield more stable returns on their capital, said Henry Tabe, a managing director for Moody's Investors Service's London office." Henry Tabe provides further historical background in his book on how SIVs unravelled during the crisis and lessons that can be learned from the sector's extinction.

In 1999, Professor Frank Partnoy

 wrote, "certain types of so-called 'arbitrage vehicles' demonstrate that companies are purchasing credit ratings for something other than their informational value. One example is the credit arbitrage vehicle, also known as a Structured Investment Vehicle (SIV). A typical SIV is a company which seeks to 'arbitrage' credit by issuing debt or debt-like liabilities and purchasing debt or debt-like assets, and earning the credit spread differential between its assets and liabilities. Much of an SIV's portfolio may consist of asset-backed securities." In reality there is no such "arbitrage", the SIV is acting like any old fashioned spread banker, seeking to earn a spread between its income on assets and cost of funds on liabilities. It earns this spread by accepting two types of risk: a credit transformation (lending to AA borrowers while issuing AAA liabilities) and a maturity transformation (borrowing short while lending long). The scale of both transformations were considerably less than traditional banks, and leverage was also typically half to a quarter of that used by banks, so the risks were less and the returns available were also much lower.

However, SIVs were originally set up as bank capital arbitrage vehicles. The introduction of Basel I regulations made holding bank capital and ABS securities expensive for a bank. For example ABS are 100% risk weighted under Basel I accords, meaning that 8% of the invested amount waste be sourced from capital. Bank capital securities, such as dated subordinated debt could be weighted as highly as to amount to a deduction from capital. That is to say all the investment would be funded from capital. A 'loophole' in the Basel accords meant that banks could provide a liquidity facility to the SIV of up to 360 days without holding capital against it so long as it was undrawn. The 'arbitrage' was therefore possible initially because the buy-side of the market for these instruments was limited.

Partnoy then questioned the economic theory of SIVs: "How is the SIV able to earn such an 'arbitrage' spread between its assets and liabilities? If the SIV is simply a vehicle for purchasing financial assets, it should not be able to fund purchases of those assets at a lower rate than the rate on those assets. If it could, market participants with low funding rates would simply purchase the financial assets directly, and capture the spread for themselves. Put more simply, if a vehicle purchases $100 million of asset-backed bonds, priced at par, with a coupon of seven percent, and it seeks to fund that purchase by borrowing $100 million, it should not be able to borrow at a rate lower than seven percent." Portnoy's theory misses the simple fact that the SIVs raised capital from third party investors with which to enhance the liabilities so these were not simple pass-through structures.

Alpha's leverage ratio was around five times. Beta's leverage was up to 10 times, depending upon the quality of its asset portfolio. Subsequent SIVs, such as Centauri and Dorada, raised the leverage to around 20 times. Typically banks are leveraged between 20 and 40 times. By 2004, Sedna was offering notes that were leveraged over 100 times that attempted to achieve a spread of 10% or more in the medium term.

At the end of 2004, there were 18 operational SIVs that managed assets then valued at a total of $147 billion. At the end of 2005, according to Standard & Poor's, SIVs represented more than $200 billion of assets under management.

As of September 2007, one paper reported: "All SIVs to date have been established in either the Cayman Islands or Jersey so as to benefit from certain zero-tax regimes available in those jurisdictions. As mentioned, the SIV will usually also establish a subsidiary in Delaware to facilitate the issuance of debt in the US domestic market. The debt issued in the US will either be guaranteed by the offshore parent, or co-issued by the SIV and the subsidiary."

Structure

The short-term securities that a SIV issues often contain two tiers of liabilities, junior and senior, with a leverage

 ratio ranging from 10 to 15. The senior debt is invariably rated AAA/Aaa/AAA and A-1+/P-1/F1 (usually by two rating agencies). The junior debt may or may not be rated, but when rated it is usually in the BBB area. There may be a mezzanine tranche

 combination of medium-term notes (MTN) and commercial paper (CP). The junior debt traditionally comprises puttable, rolling 10-year bonds, but shorter maturities and bullet notes became more common.

In order to support their high senior ratings, SIVs were obliged to obtain liquidity facilities (so-called back-stop facilities) from banks to cover some of the senior issuance. This helps to reduce investor exposure to market disruptions that might prevent the SIV from refinancing its CP debt. To the extent that the SIV invests in fixed assets, it hedges against interest-rate risk.

There are number of crucial difference between SIV and traditional banking. The type of financial service provided by traditional deposit banks is called intermediation, that is the banks become intermediate (middlemen) between primary lenders (depositor) and primary borrowers (individual, small to medium size business, mortgage holder, overdraft, credit card, etc.). SIVs do exactly the same, "in effect", providing funds for mortgages, credit cards, student loans through securitised bonds.

In more traditional deposit banking, bank deposits are often guaranteed by the government. Moreover, for ordinary depositors, there is no other alternative to deposit their cash aside from putting their money under the carpet. Therefore, even if some depositor might withdraw money from one particular bank, they will simply transfer the money to another bank. Consequently, the availability of cash for deposit in totality does not change much. Moreover, each small individual depositor has little influence over setting the deposit interest rate. Therefore, the availability of deposits/funds in traditional banking is generally stable, which is why traditional banks can borrow largely in the form of on-demand deposit from the public and conduct lending on a long term basis.

On the other hand, the money market for CP is far more volatile. There are no government guarantees for these products in case of default, and both sellers and lenders have equal power at setting the rate. This explains why the borrowing side of SIV consists of fixed term rather than on-demand borrowing; however, in extreme circumstances like the 2007-8 credit crunch, the worried usual buyers of CP, facing liquidity worries, might buy more secure bonds such as government bonds or simply put money in bank deposits instead and decline to buy CP. If this happens, facing maturity of short term CP which was sold previously, SIV might be forced to sell their assets to pay off the debts. If the price of asset in depressed market is not adequate to cover the debt, SIV will default.

On lending side, traditional deposit banks directly deal with borrowers who seek business loans, mortgages, students loans, credit cards, overdrafts, etc. Each loan's credit risk are individually assessed and reviewed periodically. More crucially, the bank manager often maintains personal oversight over these borrowers. In contrast, SIV lending is conducted through the process known as securitisation. Instead of assessing individual credit risk, loans (for example, mortgage or credit card) are bundled with thousands (or tens of thousands or more) of the same type of loans. According to the law of large numbers
Law of large numbers
In probability theory, the law of large numbers is a theorem that describes the result of performing the same experiment a large number of times...

, bundling of loans creates statistical predictability. Credit agencies then allocate each bundle of loans into several risk categories and provide statistical risk assessment for each bundle in similar manner to how insurance companies assign risk. At this point, the bundle of small loans is transformed into a financial commodity and traded on the money market as if it were a share or bond. The bonds usually selected by a SIV are predominantly (70-80%) Aaa/AAA rated Asset-Backed Securities (ABS) and Mortgage-Backed Securities

Problems

The risks that arise are the same that Banks have always faced: First, the solvency

 of the SIV may be at risk if the value of the long-term security that the SIV has bought falls below that of the short-term securities that the SIV has sold. Second, there is a liquidity risk

, as the SIV borrows short term and invests long term; i.e., outpayments become due before the inpayments are due. Unless the borrower can refinance short-term at favorable rates, he may be forced to sell the asset into a depressed market.

When a traditional deposit bank provide loans such as business lending, mortgage, overdraft or credit card, they are stuck with the borrowers for years or even decades. Therefore, they have incentive to assess the borrowers' credit risk and further monitor the borrowers finance through their branch managers. In securitised loan, those who originate loan can immediately sell off the loan to SIVs and other institutional investors and these buyers of securitised loans are the one who are stuck with credit risk. Therefore, in SIV intermediation, there is the same incentive to assess credit risk of borrowers, as they expect to hold the asset to maturity. However, the loan originators', typically a Bank's, reward is structured so that as more loans are made and sold wholesale, more commission will be earned. So there is little need for originators to monitor their borrowers credit risk. The monitoring was theoretically to be provided by rating agencies, which, rather than checking the financial state of individual clients, monitor the statistical performance of the bundled loan in totality to adjust their mathematical model. Some SIVs were able to make good credit decisions for their portfolios, and some did not.

Upon review, it is evident that the credit risk assessment conducted by these forms of lending was far more inadequate than with the traditional lending done by deposit banks (although many large traditional Banks turned out to be over-exposed to mortgage risk

 both via loans and through their investments in securitisations). Some mortgage loans even turned up to be liar's loans with some borrowers essentially being NINJA (No Income, No Job or Assets). In traditional banking, when a downturn occurred, branch managers could individually review clients' financial condition, separate good borrowers from bad ones and provide individually tailored adjustments. SIVs, on the other hand, are staffed by investment managers, who cannot assess the individual content of securitized/bundled loans, and instead rely entirely on the risk assessment provided by the rating agencies. This weakness was exposed when it turned out that complicated mathematical models, which is used to rate securitized loan, made fundamental assumptions that turned out to be wrong. The most significant among these assumptions were the trends in U.S. housing prices which declined far faster, deeper and broader than statistical model predicted.

These complex statistical analyses were supposed to function as a good substitute for risk monitoring provided by individual branch bank managers. Had the model been correct, these inadequately assessed loans would have been rated as high risk resulting in a lower price for the bond. However, when housing prices were constantly increasing, borrowers with inadequate income could cover mortgage repayments by borrowing further money against increased value of their house. This somewhat fictitious good payment record, which may be obvious if it was monitored by a bank manager, fed into the mathematical model of rating agencies whose weakness was exposed when the housing market start to tank. The credibility of credit assessment provided by rating agencies was further eroded when it was revealed that they took a cut in the sales of securitised bonds which they themselves rated. When the entire spectrum of bundled loans from sub prime to premium AAA start to under-perform against statistical expectations, the valuation of assets held by SIVs became suspect. SIVs suddenly found it difficult to sell commercial paper while their previously sold commercial paper neared maturity. Moreover, their supposedly prime rated assets could be sold only at a heavy discount. In effect, this was a run on the bank.

Though the assumption of ever increasing housing prices was the fundamental problem, there were other mathematical / statistical problems too. This is particularly important to prevent such things from happening again. There was an error in estimating the aggregate probability of default from components as the interaction effects could not be estimated with similar accuracy as the independent effect. For example if an SIV had mortgage as well as auto loans the probability of default in the mortgage part or auto part could be estimated more accurately with the law of large numbers and past data with few assumptions like "the future will be similar to past". But to estimate the likelihood of mortgage default triggering defaults in auto loans is extremely difficult as past data points will miss that largely. So even if we assume some interaction effect was taken into consideration while pricing the SIV, it was far from accurate even mathematically from the beginning.

2007 Subprime mortgage crisis

In 2007, the sub-prime crisis caused a widespread liquidity crunch in the CP market. Because SIVs rely on short-dated CP to fund longer-dated assets, they are frequently refinancing, just like Banks do. Unlike standard asset backed commercial paper conduits, SIVs do not have liquidity facilities that cover 100% of their outstanding CP. Instead, a SIV's safeguard against being unable to issue new CP to repay maturing paper is being able to sell their assets, which were purportedly highly rated and liquid.

s), and by the start of September the market was almost completely illiquid. That showed how risk-averse CP investors had become even though SIVs contain minimal sub-prime exposure and as yet had suffered no losses through bad bonds. It's a matter of debate, however, whether this risk aversion was a matter of prudence or misunderstanding by the CP market or contamination by a few SIVs that had Sub Prime exposure of the many that had little or no Sub Prime risk.
