At the moment, Steem Creation is running at 270% per annum.

800 Steem per minute, 20 of which were allocated for Liquidity Rewards. 2.5% of New Steem.
1200 x 24(hrs) x 365(days) = 10,512,000/0.75% = 1,401,600,000

There would need to be 1.4bn Steem in existence for the 0.75% per annum clause to be implemented..

Current <150m in Circulation

I am talking in terms of % of new Steem...
