DERIVATIVES AND ISLAMIC FINANCE

Muhammad Ayub
(The writer is Senior Joint Director, Islamic Banking Department, State Bank of Pakistan Karachi.)

The conventional options, swaps and futures stem from debts and involve sale and purchase of debts/liabilities. As a group, products such as interest-rate swaps, stock options and futures, currency futures etc are called derivatives i.e. instruments derived from the expected future performance of the respective underlying assets. These are very complex and risky contracts having present market value of trillions of dollars over the world. According to an article published in the Economist, some $ 128 trillion of over the counter derivatives were outstanding in June 2002, a 28% increase over a year earlier. It has been observed, however, that global financial market is becoming increasingly fragile as more and more derivatives and ‘hedging’ instruments emerge.
Just to introduce the terms to common readers, an option to buy a commodity is known as ‘call option’ while the option to sell a commodity is known as a ‘put option’. An option has a nominal size, this being the amount of underlying asset that the option holder may buy or sell at the strike price, the price at which the holder may buy or sell the underlying asset upon exercise of the option. If the price moves favorably, the option is exercised and the commodity is bought/sold at the agreed price. If the price moves unfavorably, the buyer of the option simply abandons it. Thus an option contract confers the right but not the obligation to enter into an underlying contract of exchange at or before a specified future date (the expiry date). The buyer of that option pays a price (the premium) to the seller (the writer) of the option.

We can explain the options trading with help of an example. A call option purchase at a price of say Rs 5 on bond or stock ‘A’ provides a right to Mr. M to purchase the stock at price of Rs 50 three months from now. If as per his expectations the price of ‘A’ increases to Rs 60 on the maturity date, then the buyer of the call has a net gain of Rs 5 (on an investment of Rs 5). This is what the seller or the writer of the call would lose. But if the price of the stock falls below Rs 50 on the maturity date, say to Rs 40, the buyer would allow the option to expire without exercising it since he can buy from the market at a lower price. His loss would amount to Rs 5 or hundred percent with the call. This Rs 5 would be what the seller of the call would gain on zero investment. In the game, the buyer and seller have diametrically opposite expectations. The possibility of risk and returns are magnified, the gains of the buyer being equal to the losses of the seller and vice versa.

The institutions dealing in derivates and hedge funds claim that diversity of hedging products protect their clients against market volatility and provide a larger spectrum of risk management to the benefit of the society. But, actually volatility is caused by their activities when they trade in derivatives as a part of rip-off factor and the clients are sold nothing for something – protection against a danger that never needed to exist in the first place. They may produce huge profits for financial institutions at the cost of others. But these profits are not necessarily indicative of productive efforts. Mr. Warren Buffet, Chairman Berkshire Hathaway says: Derivatives are financial weapons of mass destruction mainly due to opaque pricing and accounting policies in swaps, options and other complex products whose prices are not listed on exchanges; Credit derivatives and total return swaps that are agreements to guarantee counterparty against default or bankruptcy merit special concern.”

The macro-economic arguments for their existence are also not convincing – they are for minimizing risks which do not need to exist as described earlier. The global foreign exchange market as at present is more or less an unproductive pursuit in that it exists because of an unnecessary monetary expansion. It would be better to structure the financial system such that it does not suffer from continuing volatility. What we are seeing in the Western world is the emergence of financial products that are a symptom of a system that has gone wrong. For a more efficient economy, we must promote systems in which people work in productive pursuits rather than unproductive ones. Change the system to relate it with real sector activities
and all those clever dealers who earn huge profits out of thin air could become doctors, industrialists, business people and teachers instead! As such, Islamic financiers who look at the products of this system as a paradigm seem to be at mistake.

Study of the behaviour of the Derivatives market reveals that it has the potential to cause a serious breakdown in the financial system. The degrees of leverage that are afforded by option contracts can be so high that large unpredictable market moves in underlying prices may one day lead to the insolvency of a major financial institution. Liabilities cannot be perfectly hedged even if that is the intention, and some traders deliberately do not hedge their option portfolios because such action would limit the potential for high returns. The case of Long Term Capital Management in the United States, rescued by a Federal Reserve bail out in 1998, demonstrates the degree of risk that can be incurred. The question is whether the central bank or other authorities would be able to move quickly enough, or in large enough measure, to prevent failings.

For example, Collateralized Debt Obligations (CDOs) are sophisticated type of derivatives and clever way of exploiting anomalies in credit ratings. A number of loans or debt securities payable by various companies are put into a pool, and new securities are issued which pay out according to the pool’s collective performance. The new securities are divided into three (or more) levels of risk. The lowest, equity tranche, takes the first loss if any companies in the pool default. If nough losses eat that up, the next, mezzanine level suffers. The most protected level, the senior tranche, should still be safe, unless the collective pool has severe losses. It takes only a couple of defaults in a pool of 100 companies to destroy the equity tranche. Downgrades of investment-grade corporate bonds in America were a record 22% in 2002, according to Moody’s and it recorded bond defaults of $ 160 billion worldwide. The equity and mezzanine tranches of many CDOs have suffered severe losses; some have been wiped out. Even senior tranches, usually rated AAA, have been downgraded because losses may yet reach them. Thus, the whole concept of CDOs as in vogue refers to absolute risk and exploitation.
According to the concept of Option (khiyar) as we find in Shariah literature, the informationally disadvantaged party at the time of entering into the contract has the option to cancel the contract within a specified period. A person has also the right to undo his purchase if the seller specifically allows as part of the terms of the sale. All such forms of option are in the nature of rights embedded in a contract. In the term khiyar as used in Fiqh books we do not see any analogy that would lead us to acceptance of the structure of modern option contracts. These are independent financial contracts traded for a price that do not have any clear-cut parallel in the classical Islamic theory of contracts. Khiyar relates to a halal contract of exchange that has already taken place, whilst a modern option relates to an exchange that is yet to take place. In the case of khiyar, the exchange of one or both counter values is effected immediately while in the case of the modern option contract, future delivery applies to both the payment and the underlying asset. In addition, uncertainty as to the materialization of the exchange exists with the modern option contract but not in khiyar. A resolution of the Islamic Fiqh Academy of the OIC asserts, “Option contracts as currently applied in the world financial markets are a new type of contracts which do not come under any of Shariah denominated contracts. Since the subject of the contract is neither a sum of money nor a utility or a financial right which may be waived, the contract is not permissible in Shariah.

Most of the derivatives incorporate gharar (absolute risk), gambling and interest and support speculative activities. Islamic legal rules, particularly the ban on Gharar and on the sale of debt for debt, do not allow transactions devoid of real/productive activities. Derivatives involving such financial contracts which themselves are prohibited in Shariah (Riba based bonds & forward foreign exchange where mutual exchange is not simultaneous, for example) are clearly un-acceptable according to the Shariah principles. In case the underlying assets are equities and commodities it would be seen whether or not Riba and Gharar are involved. Experts are of the view that even in case of acceptable forms of underlying assets, a key valuation element in arriving at the fair value of an option contract remains the rate of interest. The Black-Scholes formula proposes that since an option can be perfectly hedged through constant trading in the underlying asset, the option position should be riskless and hence earn the buyer the risk free rate of interest on the premium that was paid for it. (In reality, constant trading of the underlying asset to achieve the perfect hedge is unattainable, and so option prices behave in ways that are not entirely predicted by Black-Scholes.) For the unhedged option, the contract becomes one of pure uncertainty. Neither party knows whether the option would be exercised, as it is dependent upon the condition of the market at a future date.

According to some writers ‘Arbun'can become a basis for developing some kinds of Shariah compliant options – contract by which one party buys the right to purchase from the other party specified goods for a specified price on a certain date. ‘Arbun’ is a void contract according to a Hadith and the three schools of Islamic law. Only Hanabalah uphold ‘Arbun’ with the condition imposed by some of them that time should be stipulated for the option. The OIC Fiqh Academy has also endorsed ‘Arbun’ but only if time limit is specified. Even if ‘Arbun’ is accepted as valid transaction, most of the derivatives current in the market would still be unacceptable from Shariah angle due to involvement to Gharar and Riba. A Call Option can be considered near to Bai al Arbun in the sense that the seller does not return the premium or advance payment to the buyer in case the latter does not exercise the purchase option and the buyer loses the option premium even if the option is exercised and the contract is confirmed. In case of Bai al-Arbun, however, the option premium is adjusted in sale price when the contract is confirmed. However, this subject of derivatives needs extensive research.

Samuel L. Hayes, after detailed discussion on derivatives concludes, “There are no effective derivates of Islamic debt contracts which replicate conventional risk-hedging and leveraging contracts such as swaps, futures, and options. Similarly, in the equity security sector, there are no risk-hedging or leveraging contracts in Islamic finance truly comparable to available conventional derivatives….. With respect to commodities and other goods, the Salam contract is an imperfect Islamic substitute for a conventional forward contract. The related Istisna contract for goods being manufactured for a buyer provides another partial Islamic proxy for a forward contract. It is also possible to construct an Islamic contract which partially replicates a conventional futures contract, via back-to-back Salam contracts”.

Derivatives in Islamic Finance

During the late 1980's an opportunity came my way to become an option dealer in the London capital market. At that time I was not a practising Muslim and, given that the pay in this line of work could be enormous, I accepted without a second thought. As the years went by, it occurred to me that the size of my pay packet bore little relation to the benefit enjoyed by society as a result of my work. Others had misgivings of their own. Accountants complained of the hidden risks that banks were taking 'off balance sheet' and, from time to time, government ministers would make a scapegoat of the derivatives market when other excuses were not forthcoming. Regulators scrambled to recruit staff who could understand what the traders were doing but offerred low rates of pay and, therefore, sufferred from a persistent lack of qualified staff.

As the derivatives booty trickled down in ever greater quantities, the financial establishment began to seek a wider economic justification for the existence of this market. The business schools, progenitors of modern option valuation techniques, were only too happy to help. The increasing diversity of hedging products provided a more complete spectrum of risk management tools and was therefore of benefit to society, they told us. But we in the market saw a different story unfolding. XYZ bank would lure the poorly paid treasury manager at the Kingdom of Somewhere-Or-Other into a complex swap deal that only a PhD in Nuclear Physics could properly value. So the bank would book a multi-million dollar profit the very day the deal was closed and the Kingdom's officers would never know any better. Derivatives departments began to swarm around corporate clients like bees around a honey pot.

Of course the scam couldn't last forever. By the early 1990's, Bankers Trust traders were caught discussing the size of the "rip-off factor" on a Procter and Gamble derivatives deal. We know this because the episode was taped and made public on behalf of the company. It was one of many large derivatives losses accrued by clients that had acted on the eager encouragement of their bankers. Soon Orange County and Metallgesellschaft would fall into the same trap at a cost of hundreds of millions of dollars more.

"We can protect you against market volatility" the investment bankers tell their clients. But the market volatility is caused by the activities of those very same investment bankers, and so the clients are sold nothing for something. Protection against a danger that never needed to exist in the first place. Sadly, the world learned little from the derivatives explosion. By the time the internet boom collapsed, a new generation of clients was learning about the motivations that really drive bankers and advisors. The clients tend to be offerred the products that provide financial institutions with the highest profit margin.

What if every country had pure gold coins as its currency? Then what would be the point of the foreign exchange market? What would be the point of exchanging one ounce of American gold for one ounce of Japanese gold? Who would need currency derivatives? Who would need to pay commission on foreign currency transactions? We see very quickly where this idea leads. An end to a trillion-dollar-a-day market that produces huge profits for the financial establishment. But of course profit is not necessarily indicative of productive effort. Theft is a good example of this principle. If we want to achieve a more efficient economy, we must promote systems in which people work in productive pursuits rather than unproductive ones. The foreign exchange market is an unproductive pursuit in that it exists because of an unnecessary monetary convention. Change the convention, in other words adopt a different monetary standard, and all those clever dealers can become doctors and teachers instead!

But back to options. Modern option contracts have a variety of features in common that can be summarised as follows. An option is a right not an obligation to enter into an underlying contract of exchange at or before a specified future date (the expiry date). The buyer of that option pays a price (the premium) to the seller (the writer) of the option. The option may give its holder the right to buy a specified asset (the underlying) from the option writer, gold for example, such being a call option on gold. Or the option may give its holder the right to sell the underlying asset to the option writer. This would be a put option. Every option has a strike price, this being the price at which the holder may buy or sell the underlying upon exercise of the option. And every option has a nominal size, this being the amount of underlying that the option holder may buy or sell at the strike price. A 15 December 2001 European call on gold at $400 per ounce in 100 ounces gives its holder the right to buy 100 ounces of gold from the option writer at $400 per ounce on the 15 December 2001, if the holder so wishes.

If we exclude those financial contracts which are of themselves haram (bonds and forward foreign exchange for example), then we are left with a set of underlyings such as equities and commodities upon which a derivative contract may be based.

Curiously, even where acceptable forms of underlying such as these are concerned, a key valuation element in arriving at the fair value of an option contract remains the rate of interest. The Black Scholes formula proposes that since an option can be perfectly hedged through constant trading in the underlying, the option position should be riskless and hence earn the buyer the riskless rate of interest on the premium that was paid for it. (In reality, constant trading of the underlying asset to achieve the perfect hedge is unattainable, and so option prices behave in ways that are not entirely predicted by Black-Scholes.) For the unhedged option, the contract becomes one of pure uncertainty. Neither party knows whether the option will be exercised, as it is dependent upon the condition of the market at a future date.

The first problem with the standard option contract from a Shari`ah perspective is that a contract of exchange in which both payment and underlying are deferred is widely held to be prohibited. The second problem is the uncertainty that exists with regard to whether or not the option will be exercised. Thirdly, if the option contract is judged to be halal, the question then arises as to whether that option can itself be sold to a third party, as is the case in the market for warrants for example. Fourthly, by buying a put option and selling a call option, a trader can replicate a short position in an underlying asset. Where these options are cash settled, the trader can be seen to achieve the same cash-flows as a short seller of that underlying. Shari`ah scholars have agreed that selling what one does not own is a prohibited commerical activity, and the possibility that such an activitiy can be synthesised through the use of options must therefore call into question their validity under Shari`ah. There is a fifth problem that pertains to more complex option contracts where the strike price itself varies according to an agreed formula. Such is the case with a serial option. For example, a one month 'at-the-money' serial call with daily resets gives the holder a series of one day call options whose strike price is the price of the underlying asset at the previous day's close of trading. As this price is unknown in advance, the strike price itself cannot be known. This represents further gharar.

Under Bay al-Urban, a deposit is paid on an item that a prospective buyer may purchase at a later time. Should the buyer not complete the purchase, the deposit is lost. This contract has been used as a justification for Islamic options by some writers who argue that the deposit can be seen as the premium paid by the buyer of a call option. The problem is that the scholars do not widely allow bay al-Urban. According to Ibn Rushd in Bidayat al-Mujtahid:
Within this topic is the sale of the urban (sale with earnest money). The majority of jurists of different regions hold that it is not permitted, but it is related from a group of the Tabi'un that they permitted it, among them are Mujahid, Ibn Sirin, Nafi ibn al-Harth and Zayd ibn Aslam. The form it takes is that a person puchases a thing and delivers to the seller part of the price on the condition that if the sale is executed between them this earnest money will form part of the price of the goods, if it is not executed the buyer will forgo it. The majority inclined toward its prohibition, as it is from the category of gharar, mukhatara and the devouring of wealth of others without compensation. Zayd used to say, "The messenger of Allah (God's peace and blessings be upon him) permitted it". The Ahl al-Hadith said that this is not known from the messenger of Allah (God's peace and blessings be upon him).

Under Khiyar, which is allowed by the jurists, the buyer of an item has the right to undo his purchase if the seller specifically allows as part of the terms of the sale. This is in other words an option to cancel a previously agreed sale. All buyers have a right to cancel a sale following purchase but before leaving the presence of the seller (khiyar al-majlis). This right is different to that expressly given by the seller to the buyer under sale with an option (bay al-khiyar), where the buyer may leave the presence of the seller for a specified period of time before returning to cancel the sale and take back the money that was paid.

Ibn Rushd in Bidayat al-Mujtahid comments:
Permissibility of option is upheld by the majority, except for al-Thawri and Ibn Shubrama, as well as a group of the Zahirities. The reliance of the majority is on the tradition of Hibban ibn Munqidh, which contains the words "and you have an option for three days", and also what has been related of the tradition of Ibn Umar: "The parties to sale have an option as long as they have not parted, except in sale with an option". The reliance of those who prohibit it is (on the argument) that it constitutes gharar and that the basis of sale is that it is binding, unless definitive evidence is produced for the permissibility of sale with an option from the Qur'an or authentic sunna or ijma. They also said that the tradition of Hibban is either not authentic or it is specific to the case of a person who complained to the Prophet (God's peace and blessings be upon him) that he was deceived in sales. They said that the tradition of Ibn Umar and the words in it, "except sale with an option", have been interpreted through another version of this tradition in which the words "that he says to his counterpart: 'Choose'," have been recorded.

In khiyar it is difficult to see any analogy that would lead us to the acceptance of the modern option contract as described above. Khiyar relates to a halal contract of exchange that has already taken place, whilst a modern option relates to an exchange that is yet to take place. In the case of khiyar, the exchange of one or both countervalues is effected immediately. In the case of the modern option contract, future delivery applies to both the payment and the underlying asset. In addition, uncertainty as to the materialisation of the exchange exists with the modern option contract but not in khiyar.

Disagreements among traditional scholars in the matter of khiyar arise in minor details, such as the length of time for which the buyer has the option to return the goods, or who is liable for any damage to the goods whilst the buyer is in posession of them during the option period. These scholars do not seem to have disagreed upon those fundamental principles which distinguish khiyar from the modern option contract.

It is my view, having been involved in derivatives dealing, that the potential exists in this market to cause a serious breakdown in the financial system. The degrees of leverage that are afforded by option contracts can be so high that large unpredictable market moves in underlying prices may one day lead to the insolvency of a major financial institution. Liabilities cannot be perfectly hedged even where that is the intention, and some traders deliberately do not hedge their option portfolios because such action would limit the potential for high returns. The case of Long Term Capital Management in the United States, rescued by a Federal Reserve bail out in 1998, demonstrates the degree of risk that can be incurred. The question is whether the central bank or other authorities will be able to move quickly enough, or in large enough measure, to prevent future failings.

When looked at from the Islamic perspective, as with so many other Islamic financial products, it seems that theory needs to be stretched in order to justify an Islamic option contract. The macro-economic arguments for their existence are of dubious merit, based as they are on minimising risks which do not need to exist in the first place. Better to structure the economic system such that it does not suffer from continuing volatility. If there was no such thing as interest, there would be no such thing as interest rate options. The same with foreign currency. What we are seeing in the Western world is the emergence of financial products that are a symptom of a system that has gone wrong. Islamic financiers who look at the products of this system as a paradigm are making a big mistake.
