It doesn't appear the increase in margin debt is due to shorting. Found this in my rummaging and it looks like short interest remain just about unchanged from June to July. Yes, there is some increase in short interest since the beginning of the year, but nothing to justify this increase in margin debt. It could be a good indicator for what is to come, even if some of the amount is from shorting. In April, short interest rised, while margin debt decreased as well.
Edited to reflect August information I found... a somewhat sizable decrese in short interest.. will be interesting to see what margin debt is in August.
