Blame the operational risk consultants and regulatory oversight.
In the era of increased cyber threat, environmental threats to pipeline / gas, natural disasters, general operational risks etc. etc. HUBS are the answer. In one Wells line of business alone last year there were over 900 "sites" identified in which employees were working from, thus the ORCs said NOPE.
Factor in banking stability is key to national security and real or imagined societal stressors, the ORCs have been daily whispering in the ears of the operating committee regarding aging national infrastructure, viability of staff to come in for disaster recovery and generally what the he-l we would do if California drops into the ocean setting off a greater upset in air travel while we might simultaneously be hit with cyber or power grid threats from either the homeland or from abroad.
Hubs arent going away. Signed...in the know.
