To clarify (what I think you’re talking about), CMBS ie commercial mortgage backed securities is eerily similar to the bullshit that kicked off the '80 ‘great recession’, which was speculation / shorting on MBS. I remember reading an economist at the time of '08 saying this is very bad, but he predicts we’ll just about scrape through it, followed by a long period of stagnating growth, zero lessons learned, then a crash which will make '08 look like a fender bender.
I always hoped he was wrong but day by day, month by month, I saw his prediction coming true.
