Your link shows it bottoming out in 2009-2011 after the housing crash, well below the 1992 ratio. And then a steady and mostly linear climb from late 2011 to the end of the data.

After that early 90s recession there's a steady rise to the dotcom burst around 2000, which bottoms around 03 and starts to rise again until the housing crash. Seems like a pattern. Progress until the financiers manage to tank the economy, repeat.
