That doesn't really explain anything though. Every business is always trying to gain marketshare. The question then is why they are succeeding now and not before. Nobody forced SVB to put all their money into 10-year treasuries, nor did anybody engineer the tech-industry recession we've been going through (JPMC is big but Apple, Microsoft and Amazon are each bigger), both of which contributed to SVBs demise. Also the big banks tried to rescue First Republic a few weeks ago; not impossible that was some weird 4-D chess move but much more likely it was just a bailout that failed.
