Overton Window

As we start looking for some context to understand the world better, we would need to get a better understanding of how the world works. The understanding of how ideas flow and how they become more mainstream.

Explainer: Overton window describes the stages and flow of ideas. The acceptance of a new idea in the mass public depends on that window. How quickly and if at all will there be acceptance for it.

If you are looking for a quick understanding of it VOX explains it well in this youtube video. https://www.youtube.com/watch?v=_v-hzc6blGI

You can read a brief introduction about it on Wikipedia https://en.wikipedia.org/wiki/Overton_window

  • Bank executives pushed giving loans to people who could not have paid it backed.
  • The housing market saw an increase in asset value with cheap credit and everyone having access to it.
  • Credit rating agencies were involved as marking all these loans as A++ (extremely low risk)
  • These loans were then bundled together in the form of risk and then sold to larger banks and hedge funds.
  • When the recovery of loans started, people could not pay back the loans which started defaults
  • The recovery process moved to sell assets but now with less credit available, the assets could not fetch the actual buying value. The housing market was inflated.
  • Suddenly the overall world had lost value as the assets were now worthless.
