Rather than lowering the Hbd interest rate directly to 12%, it may make more sense to gradually reduce it over six months. 17%, 16%. A sudden drop in APR will greatly reduce the price of HBD.

Hbd's high interest kept the Hive price stable. People had bought Hive from central exchanges to own Hbd. When the generous Hbd interest disappears, they will convert Hbd to Hive and sell Hive on centralized exchanges. Thus, the Hive price will decrease.
