Isn't it supposed to correct towards 1 USD?

"The primary concern of Steem feed producers is to maintain a stable one-to-one conversion between SMD and the U.S. Dollar (USD). Any time SMD is consistently trading above $1.00 USD interest payments must be stopped. In a market where 0% interest on debt still demands a premium, it is safe to say the market is willing to extend more credit than the debt the Community is willing to take on. If this happens a SMD will be valued at more than $1.00 and there is little the community can do without charging negative interest rates.

If the debt-to-ownership ratio is under 10% and SMD is trading for less than $1.00 then the interest rate should be increased. This will encourage more people to hold their SMD and support the price.

If SMD trades for less than $1.00 USD and the debt-to-ownership ratio is over 10% then the feeds should be adjusted upward give more STEEM per SMD. This will increase demand for SMD while also reducing the debt-to-ownership ratio and returning SMD to parity with USD."
