there are to many lenders and loan rate goes down
Litecoin landing is 0.0001% per day the last week
You can ask ever 100 BTC in Litecoins for rate less then 0.005%
But sometimes your position will be automatically closed if there are no lending offers in your price after 2 days.
Ripple Landing for short positions was 4.4% per day 2 days ago (17 september 2016)
I saw similar interest rate for the bitcoin a few weeks ago, but that is just for very short period of time.
The interest has dropped to about 0.021% now. There is very quite market for the altcoin at the moment.
