How to Estimate Prices for OTC Exotic Options Without a Dealer Quote

Article Quant Q&A · Author: user59094

Summary

The document discusses how someone without access to an OTC derivatives desk can study prices and payoff risks for customized options. It explains that dealers generally quote only to established desk customers, who may need product-specific legal agreements and a meaningful business commitment. It also cautions that regulatory disclosures aimed at retail investors do not imply that a desk will provide a requested quote.

For educational estimates, it recommends using implied volatility inputs and established pricing methods. Asian options can be valued with published approximations, while touch and double no-touch options can be approached through specialized models or static replication. A Monte Carlo outline simulates underlying prices under a risk-neutral process, samples fixings, and averages them to estimate an Asian option payoff; commodity modeling may also require assumptions about convenience yield. The sources and methods provide starting points, not executable dealer prices. Estimates depend on market inputs and model assumptions, and the response notes that complex products may still be priced with available tools.

Key ideas

  • OTC dealers generally quote customized derivatives only to established customers of the relevant desk.
  • Implied volatility inputs and published methods can support educational option valuation.
  • Asian option prices can be estimated with analytical approximations or Monte Carlo simulation of averaging fixings.
  • Touch-style options may require specialized models or replication approaches.
  • Model estimates depend on market inputs and assumptions, including convenience yield for some commodity options.

# Requesting for price?












Just for education purpose. Assuming I have some trading ideas that involves the use of OTC derivatives but I may not be able to put them into practice due to regulatory issues and huge minimum capital requirements.

Can I get the pricing(i.e the max return and max risk payoff) of a custom made derivative(might include an Asian, touch/no touch options, lookback et cetera) from a bank or an issuer even though trading those products are only available to H.N.W.I and professionals traders?

Thank you in advance for any help provided.

As @noob2 noted, nobody is going to quote you a price unless you're a customer. And when I say "customer", I mean "customer of the desk", not just of the bank. Would require an ISDA covering the specific product area + some commitment to minimum 'spend' with that business line.

If you need this for educational purposes only, you can basically get all you need from reading papers. For example, Asian options are not always cheaper than their plain vanilla counterparts.

Risk or return details may be something for retail investors due to regulation like priips but no desk will usually provide this when you request a quote (RFQ).

If you would like to do it all by yourself, none of your products are particularly exotic. If you want to get an idea of pricing for educational purposes, you can start by looking at websites like investing.com where you can get implied vol quotes like shown in this question.

Once you have IVOL, you can get reliable prices for many products fairly easily with existing online tools. E.g. this question discusses touch option pricing in quantlib. Even more complex double no touch options have static replications as Uwe Wystup points out in his mathfinance newsletter.

The CME group offers listed Average price options. That is another terminology for Asian options. On top of that, it is relatively simply to price Asian options.

```
Turnbull, S. M., and L. M. Wakeman (1991): “A Quick Algorithm for
Pricing European Average Options,” Journal of Financial and Quantitative
Analysis, 26, 377–389

is one such solution. Another one is Krekel 2003. There is also

```
M. Curran, Valuing Asian and Portfolio Options by Conditioning on the Geometric Mean Price,
Management Science 40 (1994), 1705.
```

Matlab has an implementation for the Turnball Wakeman method. Quantlib is discussed here for example. I suppose other platforms / languages will have similar pricers as well.

You can also get a fairly reliable result with simple Monte Carlo simulations. For example, you can model commodity options using the following dynamic: $$\frac{dS(t)}{S(t)} =\bigg(r \ - \ y - \frac{\sigma^2}{2}\bigg)dt + \sigma d\hat{W_{t}}$$ Integrating this equation between $t=0$ and the end $t=1$ provides the generic equation used in many Monte Carlo simulations: $$ S(t_{1}) = S(0) * exp \bigg\{ \bigg(r \ - \ y - \frac{\sigma^2}{2} \bigg) \ * \ t_{1} \bigg\} $$ Where y denotes convience yield which is unobservable. However the formula for a forward price can be used to retrieve y. This simulation generates the fixings in between the start of the fixing period and the end of the fixing period. It is simple to compute the average fixing: $$ a_{1} = \frac{S(t_{1})+ \ ... \ + S(t_{n})}{n} $$ where S is the fixing at each day of the fixing period (for each iteration) and n is the number of fixing periods. Methods for Lookback options are discussed here. For education, many universities have Bloomberg. You will get quite reliable values for all of the products you mentioned by using the available pricers. A related question may be how you get trade ideas for these options without knowing what they are worth (or how they are priced).
