It doesn`t make any sense!

Earlier this year (2017) the Federal Reserve stated that they are to reduce their balance sheet this year. By reducing their balance sheet, it means that they off-load DEBT THEY HAVE BOUGHT from banks/ companies, in order to ease the financial stresses of those banks/ companies. Just recently, the Bank of England has increased its own balance sheet, by BUYING DEBTS from APPLE U.K. Other Central Banks are also increasing their balance sheets too, to take financial stresses away from banks and companies which have large liabilities! It doesnt make any sense whatsoever, that one Central Bank (the FED) are doing the total opposite to many other Central Banks around the world! Are the FED being deceptive or just clueless as to how to combat the problems (which they had a very large hand in creating)!?! PLUS, if Central Banks are buying a companies debt from them, to reduce the liabilities/ RISK of those companies... That doesnt fill a person with confidence that economys around the world are actually healthy, or in fact the WORLD ECONOMY!
