(16)Finally, as regards the effective application and enforcement in an equitable and non-distortive manner so as to ensure effective supervision and enforcement in that third country, the JFSA has broad investigative and surveillance powers to assess compliance with margin requirements applicable to OTC derivative contracts not cleared by a CCP. The JFSA can take a wide range of supervisory measures to prevent any breach of the applicable requirements, such as a business improvement order based on Article 51 of FIEA and other supervisory measures based on Article 52 of FIEA. Those measures should therefore be considered as providing for the effective application of the relevant legal, regulatory and enforcement arrangements under the OTC derivatives rules of Japan in an equitable and non-distortive manner to ensure effective supervision and enforcement.
