Minimum ticket size requirement sets issuance and transfer thresholds, permitting amortised trading when below the threshold. Regulation sets a minimum ticket size for issuance of securitised debt instruments and defines ticket size as the investment by a single investor. It prescribes differentiated minimums for subsequent transfers depending on whether the originator is regulated by the central banking authority and whether the instrument has listed securities as underlying, tying the transfer minimum in the latter case to the highest face value among those securities. Instruments with amortisation structures may be traded at amortised value when ticket size falls below the prescribed minimum.
