The last hard fork actually increased the printing of HBD since any token put into savings will earn 10%

Yes and no. The hard fork changed things so only savings earns interest. Previously all HBD even if not in savings earned interest. After the hard fork witnesses raised the rate from 7% to 10% but the amount of interest being paid out probably declined because the large amount of HBD held by exchanges and DHF became excluded from interest.

Also there is one more way to create HBD, which is through DHF. Some of the HIVE (ninja fund) in DHF is autoconverted by the blockchain to HBD daily, and any amount of HIVE sent to DHF is instantly converted to HBD. The primary source of HIVE sent to the DHF is from the HBD stabilizer proposal (about 50K HBD per day).

Finally, HBD in the DHF doesn't count toward the 10% limit. That's approaching 6 million out of the current total of 25 million.
