BitVC - Huobi's new platform - has swaps at a minimum interest rate of 0.1% and a maximum of 1%. Looks like this is only for CNY/BTC/LTC - in which case it is a very high rate for BTC and LTC, and a reasonable rate for CNY.
https://bitcointalk.org/index.php?topic=662221.0Does anyone have more details?
It'd be interesting to know if their swap rate tracks the Bitfinex USD rate.
Thanks for giving BitVC a try. I still have several invitation codes left, so if anyone is interested please send me a private message.
