Central Banks Now Operating as One Global Monopoly?

"Central banks' joint efforts sustain global system ... Never before have the world's central banks sent so much money sloshing through the global financial system. From slashing interest rates and buying government debt to dangling cheap loans to banks and taking on their risky assets, central banks have taken extraordinary steps since the 2008 financial crisis to nurse the international banking system back to health. Over the past 3 1/2 years, the central banks of the United States, Britain, Japan and the 17 countries that use the euro have pumped out so much money that their balance sheets have reached a combined $8.76 trillion. That's a record, by far. The infusion of money has eased borrowing costs and raised confidence in banks, governments and companies."
