In hardfork20, there's no plan to kick out sbd from the market. In fact, the debt ratio i.e sbd/Steem will be increased to 9%.
You may ask this because you might have noticed that sbd is no longer added to your payout. That is because sbd with a current market cap of ~16 million and Steem about 255million, the debt ratio is about 6% which is created that the acceptable 5% debt ratio, therefore it has to stop printing.
And definitely if it stops printing(paying out) it will be scarce and there there is demand for a scarce products it inflates the price
