Since 1975 the growth in Credit for Corporate and Non-Corporate Business has been about the same. During the Great Recession they strongly diverged and have not come back together.
Interesting for Corporations the slowdown in credit growth this time around was about the same as the dot-com bust and the recovery occurred earlier.
For non-corporate business the dot-com bust was a slow motion decent that never went very deep. This time around it was free fall and we are still not back above zero.
