I don't think that's whats happening. Basically, in a repo you have one party posting a treasury bond as collateral and being lent the equivalent amount of cash. There's an interest rate you're charged on the cash, and potentially a "haircut" on the amount of cash relative to the value of the bond that a bank might take if they decide the other party is a risk and they want more collateral posted.
What you're describing is an increase in "haircuts" in these transactions between banks, but I haven't heard anyone report that has been happening. It has been, more simply, that too many people are showing up with bonds and want cash and too few people are showing up with cash and want to lend it. So the interest rate has risen
