## Question put to the AI subject

An FCM operations guidance note on Regulation 1.44 margin call timing stated that Appendix A currencies (AUD, CNY, HKD, HUF, ILS, JPY, NZD, SGD, ZAR, TRY) have a one-additional-business-day (T+1) deadline and that all remaining non-USD fiat currencies default to same-day collection. Under §1.44(f)(2), the Appendix A deadline is the end of the second business day after the margin call is issued (T+2, not T+1), and §1.44(f)(3) provides a T+1 default for all other non-USD, non-Canadian-dollar fiat currencies — not same-day. The response collapsed three distinct regulatory tiers into two.

## AI subject's verbatim answer

For margin called in a fiat currency other than USD, the deadline may be extended by up to one additional business day... T+1 should be the default presumption... For all other non-USD currencies, default to same-day (T)

## Verbatim regulator text contradicting the answer

> Payment of margin in currencies listed in appendix A to this part shall be considered in compliance with the requirements of this paragraph (f) if received by the applicable futures commission merchant no later than the end of the second business day after the day on which the margin call is issued.
