In India, we have the Banking Codes and Standards Board of India (BCSBI), Indian Banks Association (IBA), Foreign Exchange Dealers Association of India (FEDAI), Fixed Income Money Markets and Derivatives Association of India (FIMMDA), etc. that provide guidelines/guidance on various aspects relevant to the structuring of banking products.
Such guidance, being based on good market conduct, also needs to be complied 4  BIS central bankers’ speeches  with. I must also sound a note of caution here. The inability of the financial market players to ensure fair treatment to consumers and their indulgence in unfair market practices has forced some of the jurisdictions to create a separate market conduct regulator.
