I have some disagreement with the change in monetary policy under the current market value of HBD. It should be self evident that any measure that increases the buying pressure of hive dollars when it is overvalued doesn't help bring the price down to the target of 1 USD.
However it might help bring it down closer to the peg for one counterintuitive reason: The main receipients of the benefit of having interest paid for holding HBD are the exchanges since they hold the majority of the supply (I think). They might decide to cash in on the interest paid on a regular basis.
Although the increase in supply that comes with having a positive interest rate is minuscule so I doubt that it makes any diference especially with such a low APR.
