Liquidity crisis began Feb 28th, even the 10 & 30 year treasuries have very thin liquidity - this is big red flag and why the Fed is now committed to pumping $1.5T into the market, which is more than the entire QE1. Now its QE infinity.
The Fed/central banks have created such huge distortions & made the market very fragile, when they are not juicing it look out below!
For stock indexes ETH trading I have been mostly trading the Nikkei (Singapore/Osaka), it has far greater book depth & stable spreads.
Rumors are that some hedge fund mgrs are freaking out about finding some of their older 10 year treasuries are not legit, meaning they are worthless.
