You said, "We've been there before. Back then, the brokerages didn't take DTC as seriously as they do now. They should have, but they didn't. Even today, different brokerages take different attitudes toward chilled stocks. Generally speaking, global locks are treated more seriously." That is incorrect in my opinion. The DTCC is owned by the very banks and brokers (being full participants) it serves; consequently, it is self-serving, and is dedicated to keeping a solid wall around it's operations to the detriment of main street. My opinion.
https://en.wikipedia.org/wiki/Depository_Trust_%26_Clearing_Corporation ...Several companies have sued the DTCC, without success, over delivery failures in their stocks, alleging culpability for naked short selling. Furthermore, the question of whether DTCC is culpable for naked short selling has been raised by Senator Robert Bennett and the NASAA, and discussed in articles in the Wall Street Journal and Euromoney Magazine.[20][21] DTCC contends that the suits are orchestrated by a small group of lawyers and executives to make money and draw attention from the companies' problems.[21]...This statement cannot be 100% in all cases. A blanket is put on the true suits and all others in the guise of attention seekers. Thus, no one can successful climb the "wall" of the DTCC. In my opinion.
