Step-up CDBs
You can now create floating-rate banking bonds with a progressive rate (step-up CDBs), in which the percentage of CDI changes on predefined dates.
The Create Security endpoint accepts two new optional fields for FLOATING_RATE_BANKING_BOND securities:
scaleType:INCREMENTAL(the new rate applies only from the change date onward) orRETROACTIVE(once the change date is reached, the new rate applies from the bond's start). The default isNONE.scaling: the list of rate changes, each with its date (date) and the newmultiplier.
The multiplier field still indicates the rate in effect at issuance. Both fields must be sent together, and step-up rates are accepted only for bonds indexed to CDI, without spread and with interestPaymentPeriod equal to BULLET. The List Securities and Read Security by ID endpoints also return scaleType and scaling.
