Todai Finance Innovation Program Lecture 5 Report
The 5th Lecture “Securitization and Derivatives” of the Todai Finance Innovation
Program was held on 20th June at the Kojima Conference Room of the Economics Research Annex
at the University of Tokyo Hongo campus. It served as a continuation of the 4th lecture and the topicof securitization, although it had a particular focus on derivative products and their concept. The
lecture was led by Mr. Hidetoshi Ohashi, who is currently Chief Credit Strategist at Mizuho
Securities. The lecture was divided into four sections: 1) Current Financial Market Environment 2)Securitization 3) Derivatives 4) Securitization, Derivatives and the Financial Crisis of 2008.

Section 1: The Current Financial Market Environment
Unlike before the 2008 Financial Crisis, currently the majority of the world’s countries
are struggling to achieve economic growth. Even countries such as China and Brazil, who had been
experiencing higher growth until recently are facing slowdowns in their economies. Why is this?
There are said to be three major drivers of economic growth –increasing population,
increasing productivity and increasing leverage. As the result of the Financial Crisis of 2008 stricter
regulations were introduced for financial industries, which has made it more difficult to utilize
leverage. This has been coupled with the fact that many countries are experiencing large slowdowns
in population growth rates, and productivity has begun to plateau. This is exemplified by Japan,
which fulfills none of the three listed conditions above that contribute to economic growth. Despite
the best efforts of the BOJ and its untraditional and accommodative monetary policy, the situation
remains largely unchanged. In order to increase leverage there must be a move away from thetraditional low risk low return investments, and increasing investment in non-traditional assets suchas securitized products, or financial products of foreign countries, or assets with lower credit ratings.

Section 2: Securitization
Traditional methods for financing money include bank loans or issuing stocks. However,other alternatives such as securitization exist (as discussed in the previous lecture). At the moment inJapan, perhaps around 50% of institutional investors cannot invest in a bond BBB-rated or below..
However, if you cut away the assets and securitize, it is possible to create an alternative forinvestment with a stable cash flow, track record, and a higher credit rating. In such a way underlying
assets with too low a return or too high a risk may be repackaged through securitization andtranching to create investment options with various risk profiles to meet the needs of a wide range ofinvestors.
The previous paragraph highlighted the benefits of securitization for the investor, butsecuritization also poses incentives for the issuer. The following example will explain how the issuer
can benefit from securitization through arbitrage. It will assume a whole tuna as the original asset.
The different tranches (Senior, Mezzanine, Equity) can be considered as the different grades of tunameat (Akami (lowest), Chutoro, Ootoro (highest)). The whole tuna generates 8% yield, however, thecurrent value of the tuna itself is locked up and cannot be put to use elsewhere. This problem can beovercome if you decide to securitize the tuna, where it is possible to raise funds, which may be used
for other purposes, while still receiving the 8% yield. In return you must pay the investors their yield,
but this only amounts to 4.6% as opposed to 8%. This shows how securitization may be used tolower procurement costs. The mechanism is summarized in the figure below:

There are three types of Asset Backed Securities: MBS, ABS and other ABS. MBS(Mortgage-Backed Security) is the term used when the asset backing a security is a mortgage or acollection of mortgages. ABS in its narrow sense refers to when assets such as credit card debt, autoloans, student loans etc. act as the security, and other ABS covers leases on assets such as shipping
containers or aircrafts, CLO/CDO, or WBS (Whole Business Securitization) among others.
Section 3: Derivatives
The concept of derivatives is heavily rooted in decision-making. Generally speaking, themore you delay a decision the greater benefit you receive, as it gives you more time to obtain new
information which may be used to make the decision. For example when deciding who to marry, at
the age of 50 you will probably have a better idea of your ideal partner than at the age of 20. Hence,
if we ignore the negative sentiment attributed to aging and do not consider the fertility decline, wecan conclude that there is much less risk in marrying at 50. Applying this to the business world, if afirm is considering capital investment to construct a new factory, there is benefit in waiting to see
whether the product that the factory will produce actually sells or not (although opportunity cost
exists in the form of lost sales). This decision making process is the core concept of derivatives.
Derivatives are financial products that are derived from real assets such as bonds,commodities, currencies, interest rates, market indexes, and stocks. They contribute greatly to theliquidity of markets as they can be used to hedge against risks. They also serve an important functionin pricing where there is no yield curve available, or as a measure of risk such as in terror futures.
Derivatives have the following three main characteristics:
1) Off balance – At the time of the trade there is no capital value2) Leverage – Because it is just an option, no need for large amounts of principal
3) Risk Trading – Profits/Losses dependent on market movements of underlying asset
Typical derivative products
Futures - A futures contract is an agreement to buy or sell a particular commodity or financial
instrument at a predetermined price at a specified time in the future. The month in which the contract
expires is known as the “contract month”. For the contract to be settled, delivery or expiration mustoccur.
Options - An options contract is an agreement between two parties that grants the owner the right tobuy or sell shares of the underlying security at a preset price, referred to as the strike price, sometime

in the future. However, in return for this right a premium must be paid. With European Options youcan only exercise the option at the expiry date, whereas with American Options you can exercise theoption anytime before the expiry date. It is possible to combine options together for different
strategies. Various pricing models exist for options, which take into account factors such asunderlying price, strike price and days until expiration. The Black-Scholes formula was the firstwidely used model for option pricing.
Section 4: Securitization, Derivatives and the 2008 Financial Crisis
Since the Financial Crisis of 2008, the value of outstanding bonds in relation to GDP has
been increasing, while on the other hand the value of securitized products in relation to GDP has
been decreasing. This is reflective of the bad reputation securitized products and derivatives havegained as a result of their role in bringing about the crisis. However, Mr Ohashi strongly emphasizedthat the problem did not lie in the products themselves, but rather the system of procuration
employed. The following paragraphs will examine the issue in closer detail.
One financial instrument that played a significant role in the issue was Synthetic CDOs.
Synthetic CDOs are a form of Collateralized Debt Obligation that differ from usual CDOs in thatthey are not backed by assets such as bonds and loans, but rather credit derivatives. What happenedin the lead up to the 2008 financial crisis was that the spreads of the underlying assets became tight,
which meant a larger senior tranche was required. This resulted in the creation of a large supersenior tranche, which essentially function to apply leverage.
What was the problem?
Synthetic CDOs were said to have only
accounted for 1% of GDP. Logically this would
imply that even if all the Synthetic CDOs
defaulted there would only be a 1% loss at mostin GDP. However, the reality was muchdifferent. The reason lay in the structuring usedin the funding such products where there existed
a Asset-Liability Mismatch. This is represented
in the figure to the left.

In Detail. ABCP Conduit (total value approximately 1 trillion USD) was commonly used,however, it was composed of various securitized assets such as ABS CDO or those derived from
sub-prime mortgages and home equity loans etc. These various securitized assets were in turnfunded using ABCP, which is where the Asset-Liability Mismatch occurs. Therefore the true
problem lay in the way that these products were financed, utilizing ABCP rather than more stablefinancing resources such as long-term debt. Considering such ABCP assets held a total value ofapproximately 1 trillion, and the fact that the GDP of the United States at the time was around 14trillion, it is clear that value losses in the assets would have a substantial impact on the country GDP.
In 2007 the value of ABCP started to decrease rapidly, so it was no longer possible tocontinue financing through ABCP. Therefore there was no choice but to sell. The forced selling tomaintain enough liquidity meant that the pricing mechanism did not function, and as a result theprice began to plunge. The situation was made worse by the fact that within the assets were not only
securitized products but also subordinated debts of investment banks. These subordinated debts ofbanks also got sold in a similar fashion. The fact that these banks were the ones providing liquidity
supplementation led to the reputation of the investment banks declining. Eventually they became
unable to generate funds and collapsed, with the obvious example being the Lehman Brothers.
Currently many people will not touch the securitized or derivative products discussed inthe above example or in general as a result of these happenings. This is completely away from thepurpose of these products and hence there is a need to change their reputation for the better so thatthey may positively contribute to the market. In order to achieve this it is important to spread theunderstanding that the root of the problem was in the way such products were financed rather than
the nature of the products themselves.
Recently the FinTech trend has lead to innovation in the provision of financial services,
but the development of financial products themselves has not been seen for over 40 years. Although
there cannot be much expectation in terms of the development of new financial products, Mr Ohashi
believes that decision-making can be made clearer and more efficient through the development ofequations or formulas. This would aid companies in making logical decisions and contribute tocompany management and the real economy. At the moment such decisions are largely dependent
on individual experiences and senses, and do not always result in the most beneficial decision being
made. Therefore going into the future, the development of a model to weigh up different factors in
the decision-making process can no doubt help companies to make better management decisions.
