What is forex derivative losses and what is the impact of this in indian stock market? -

Currency: Derivatives are financial instruments whose value changes in response to the changes in underlying variables. A financial contract whose value is derived from the performance of assets, interest rates, currency exchange rates, or indexes. Derivative transactions include a wide assortment of financial contracts including structured debt obligations and deposits, swaps, futures, options, caps, floors, collars, forwards and various combinations thereof. Numerous accounts of derivatives-related losses experienced by established and reputable firms have raised concerns over the rapid growth of derivatives markets. Two of the largest derivatives-related losses to date involved Metallgesellschaft AG of Germany and Barings PLC of England, which both lost over $1 billion. Such incidents often lead to demands for stricter regulation. But a careful study of these incidents suggests no need for sweeping regulatory reform. It does suggest a need for greater international cooperation among regulators, however.
