What are three reasons why the glass-steagall act became less and less effective?

Answer: The Glass-Steagall Act was no longer preventing activities it was meant to prevent.

Explanation: 1. regulations covered fewer financial instruments as new financial instruments were developed. 2. Financial markets were becoming global, and U. S. regulations controlled only U. S. financial institutions. This reduced the ability of the United States to strictly regulate many financial institutions and 3. There was political pressure to reduce regulations, since people forgot that regulation had successfully controlled past banking problems.
