I would like to find the time to articulate a comprehensive vision of what role park rates should play now and as Nu matures and grows. I will just mention a few quick points here.
Park rates are not very important right now, but I expect their importance to increase. Before they can become really important, there must be a large lending market in NuBits. Today, there is no discernible lending market. We need an active market in parked NuBits in order for them to be effective in peg support when we need it. Therefore, I believe park rates should be offered constantly, even if the rate is very low.
Our current task is to develop a market in parked NuBits. We need to balance the costs of paying the park rate and the benefit of developing this peg supporting mechanism. There has recently been a surge in parked NuBits, to $427,000 total. The total cost of premiums is less than $10,000. This means a little less than 4% of the currency supply is parked. It is a significant but still modest proportion.
As a reaction to the increased demand, I recommend minting shareholders reduce the park rate to 17% from its current 20% rate, for a period of a year or less.
