my guess is that this is good????
Sounds like it to me.
I’m no economist, but I’m guessing it’s good news for the short term. I’m not so sure about long-term.
Yes and no.
Yes, because it inject some liquidity into the US Fed on the short term.
No, because the co-ordination indicates the central bankers are starting to grasp at straws - especially the Fed. The Fed perceiving a need for this type of co-ordinated action between this many central banks means that the Fed feels the situation is starting to get away from them - quickly - and they foresee a possible need for more money in the near term than the Treasury has at its disposal to dump into the Fed.
Not if you want to avoid hyperinflation
