Bloomberg DLIB and BLAN for Pricing Bespoke Derivatives

Article Quant Q&A · Author: jakub
Read the original

Summary

The document describes Bloomberg's DLIB suite as a toolkit for pricing and calibrating derivative structures, with templates for some exotic products. It presents BLAN as an option for building bespoke deals from scratch and experimenting with different models when the available templates do not meet the user's needs. In this account, BLAN can support complex structured payoffs, while Bloomberg staff may also build pricing functions for clients.

The only explicit limitation discussed is the learning curve. The response does not compare Bloomberg's tools with competing valuation services in a systematic way, and it provides no details on supported instruments, model validation, calibration quality, implementation constraints, or pricing performance. It is a broad practitioner description rather than a technical guide, so users evaluating the platform would need further information about their specific products and modeling requirements.

Key ideas

  • DLIB is described as a toolkit for pricing and calibrating derivative structures.
  • DLIB includes templates for some exotic structures.
  • BLAN is presented as a way to create bespoke deals and work with different models.
  • The response identifies a substantial learning curve but gives no detailed comparison with competing services.
  • The platform description does not establish model accuracy or coverage for any particular product.

Did anyone work with Bloomberg scripting language (BLAN is the name I guess). If so is it really flexible and is it competitive with other valuation services (say Super Derivatives). Does it enable you to create complex structured payoffs? What are possible problems when working with it?

this is a very old post and I hope by now you have mastered BLAN. However, Bloomberg's DLIB suite in general is a very comprehensive toolkit which enables you to price and calibrate derivative structures. A number of templates are available for exotic structures. Should this is not enough, you can go to BLAN whereby you can create from scratch any bespoke deal you would ever wish for and also play with different models. Obviously it has quite a bit of a learning curve. Bloomberg people can also code in pricing functions for you.
