Featured Structure: Shariah Compliant Principal Protected Notes By Nikan Firoozye, PhD

Wednesday, March 17, 2010

Nikan has over 14 years experience in leading Wall Street and City firms on the buy and sell-side including Lehman Brothers, Goldman-Sachs, Deutsche Bank, Sanford Bernstein Alliance, Citadel and Nomura where he is currently Head of European Rates Strategy. He has worked in a variety of primarily technical or quantitative fixed income roles from Rates & Hybrids Structuring to Rates Strategy and Quantitative Modelling to Asset Allocation and Risk Management to Prepayment Analysis and Securitization and Capital Markets. Education: PhD Mathematics (Courant Institute, NYU), Asst Prof University of Illinois.

The Structure: At the risk of being mundane, but for the sake of completeness, we wanted to describe a principal protected structured product in greater detail. How can we have benefits with no downside risk in Islamic Finance? Well, the answer is really quite trivial.

For one thing, we have already talked about Shariah-compliant call options, specifically call options thru debt set-off (see reference link). This is just one of many possible mechanisms for a Shariah compliant call option to be manufactured. Additional methods for generating calls (some are yet to be discussed here) include he following:

  • Set-off (as discussed, combining Salam and Murabaha contracts with the same counterparty together with a contractual set-off)
  • Bay' al Arbun (downpayment with revocation sale, as allowed by Hanbalis, now with much wider acceptance)
  • Wa'd (which will be familiar to the concepts unilateral promise, promissory note, estoppel)

There are probably less natural ways of synthesizing calls through profit-rate swaps (i.e. PRS - rolling and offsetting murabahas) and total-return swaps or Islamic swaps (i.e. TRS - rolling bilateral Wa'ad). Both of these are means of synthesizing a swap which can be used to generate a series of more or less risky cashflows in place of a simple call option.

A conventional principal protected note is merely the combination of a zero-coupon bond and some call options, with their maturity and exercise set to be identical. So if we invest $100 and the zero rate for 5Y is X%, the price of the zero is 100/(1+X%)**5 and the remainder is invested into calls, typically struck at spot. Depending on the prevailing rates and underlying volatility, it may be possible to give more or less than 100% of the upside of the underlying (which can be equities, commodities, etc).

The last thing needed for the structure is a zero-coupon bond/money market instrument. This can be obtained through a number of ways, including:

  • Commodity Murabaha/Tawarruq'
  • Bay al Inah (sale at spot, resale with deferment and increase)

Hence an Islamic principal protected note is the combination of a Murabaha and Islamic call options, with matching maturity and exercise.

Notes for Prospective Buyers/Remarketers

Once we let the cat out of the hat with a Shariah-compliant call option, and we've had a risk-free rate/money-market/zero-coupon bond for some time, combining the two was inevitable. In fact, the distinction between the risk-free cashflow (the Murabaha) and the more leveraged and technically challenging risky portion (with a floored downside portion) is more than trivial. This is because some redistributers choose to source only the risky component from international investment banks, and effectively issue their own zero-coupons, packaging them together at the final stage. It would be possible as well to use this Murabaha + Risky Investment (with floored downside) as a basic model for CPPI-based strategies (constant proportional portfolio insurance, essentially a portfolio strategy similar to dynamic hedging/replication of options, something we will go into more detail in a future article).

The payout will be the original principal + M *max(Price(T)-Strike,0), where Price(T) is the price of the equity/commodity at maturity of the note, Strike is usually set to Price(0), today's price, but can be set wherever we like (slightly harder from a Shariah perspective but should be just fine), and M is the multiplier. We can get anywhere from say around 70% to 120% multipliers (for instance 70%-120% of the upside of the FTSE 100). The multiplier is usually the only figure that can be manipulated, so we must look to it and compare.

While this may appear wonderful to some, we should comment that, unlike more vanilla products (e.g., straight call options or zero-coupon bonds), pricing is not as easy to replicate and it is not absolutely trivial to know whether you are getting ripped off or not. Some useful guidelines:

  • Know what you can about pricing: Try to price the call (with correct strike) and zero independently. Pricing the zero should generally be the easiest part.
    • If the underlying is liquid and calls are traded on it (e.g., calls on oil, calls on gold, etc), then it is likely that only at-the-money (ATM) options are active (i.e., ATM struck at the forward price). Spot-struck options are generally less liquid, involve pricing on a skew, which you as customer are not as aware of. Expect hidden fees.
    • If the underlying is liquid but calls are not actively traded (e.g., DJIM Index), the bank will use calls on whatever similar futures that they can get ahold of. The basis or the fact that these two index that they can use to hedge and that the underlying index in the note do not mimic each other exactly--they will charge extra for that. So on top of the skew, you get charged for their inability to hedge perfectly.
    • Make sure you know whether dividends are paid to you or are not. Does the index accrue with no dividends? It makes it cheaper for them to pay it to you, and they should pay you that much more (i.e., the multiplier on the upside should be larger, e.g., S&P offers a price index with no dividends, and a total return index. Owning the market is more like owning the total return index, but most structured products pay the price index and consequently can usually pay higher multiples, e.g., 115%, 120%, etc).
    • It's oftentimes trivial to price a Treasury, Gilt, or Bund zero-coupon bond of the same tenor. It may not be as easy to price a zero-coupon bond of the underlying counterparty.
  • Shop around: Note that even though it seems like rocket science, it isn't. Every bank and their brother does this same deal. Smart users will ask for several quotes, even of Shariah-compliant products like this (vanilla shariah-compliant). Banks are used to giving quotes for reverse-engineered products (i.e., customer describes payout, bank finds price). Banks charge different amounts: traders reserve different amounts of P&L for possible rehedging costs and model errors (releasing it gradually as the hedging costs turn out to be lower than worst-case) and sales-people take varying PCs. Redistributers are usually upfront. By the time the end-user has it, 2 points to 10 points could have been taken from the mid-price (really!). That is, you paid 10% upfront for the privilege of running this simple strategy. Smart buyers will ask for quotes from 10 banks, pick the best price and expect to pay 1%-2%.
  • Beware Winner's Curse and Counterparty Risk: Sometimes the best price has a string attach--the bank themselves didn't charge enough to rehedge the product. This is not your problem until it may actually be your problem. Be careful and concerned about counterparty risk. Seemingly safe notes turn out to have a large credit component which could result in a loss of principal (if the note issuer defaults). Know the terms for the risky-cashflow (which is oftentimes generated by the investment bank, usually different from the issuer) and what happens in case of credit events. Usually it is the issuer who takes on the credit risk underlying the risky cashflow and insists on collateralization, but this is not the case for certain types of structures (e.g., Repacks) and it makes sesne to be sure of all the contingencies.
  • Know what will affect repricing: As opposed to the payoff (the pricing before maturity) something of importance for client reports, if it was bought on a margin which doesn't sound so shariah-compliant anyway, or if you might seek to unwind the product before final maturity. Lower prices do not necessarily imply the payoff is really impaired of course:
    • Credit Spreads. Whose Zero is it anyway? The commodity was bought and sold and now you have credit exposure to a large German or Swiss bank or worse yet, an American bank. If they get downgraded, you better believe the pricing of your product (prior to maturity) will look bad. If they file for Chapter 11, it could look far worse.
    • If volatility drops and suddenly the world looks less risky, your valuations may suffer. You are long an option and option prices drop when vol drops. Your pricing before maturity depends very much on vol and it dynamics and the whole skew shape (interaction between the underlying price levels, strikes and vol).
    • If prices rise of course, you are long a call and should expect your valuations to rise. This may be less than you think since the rise will be proportional to the call's Delta (calculated from Black-Scholes or some other fancy option valuation model). The more ITM (in the money) your option is, i.e., the more underlyings have risen in the past, the greater your price sensitivity. The more OTM (out of the money) your option is, i.e., the more you've lost, the lesser your price sensitivity. Higher volatility will lessen sensitivities in general.
      It pays to read up on option pricing, to get an intuition for how it works in the real world.

Structured Product, whether we take the view that it is Islamically acceptable or not, has both some pros and cons. More importantly, it is pushed by investment banks often because it is exactly what the clients want, but at the same time because the fees can be juicy, the pricing is often opaque, and the customers are not always up to snuff. Make sure you are.
