JPMorgan and Deutsche Bank are rationing hot water and turning down the lights ahead of a chilling winter as banks prep for Europe’s energy crisis Hi. I''m Aaron Weinman . Wall Street banks — both US and European — are quite literally turning off the spigots to preserve energy across their European offices, which are preparing for a chilling winter. Firms like JPMorgan and Deutsche Bank are shutting off hot water and water fountains to mitigate the impact of the Russian government''s decision to stop the flow of gas to Europe via the Nord Stream 1 pipeline. Russia — which was hit with sanctions after President Vladimir Putin chose to invade Ukraine — said Nord Stream 1 wouldn''t reopen until those sanctions were lifted. JPMorgan''s European offices have carried out power outage simulations , tests which help the bank prepare for a loss of power. The Russian government''s decision to stem the flow of gas to European countries — which are heavily reliant on energy from Russia — is having a knock-on effect to various parts of the global economy from utilities bills to foreign exchange volatility (stock up on your USD!). Let''s dig into it.
