When the banks were in trouble about a decade ago, there were a lot of methods that governments used. One of the methods that allow the banks to function is called quantitative easing. This helps with making sure that people can get a surety bond and taking care of everything that needs to occur so that the economy can grow.
What is quantitative easing? The long and short of it is that quantitative easing allows banks to give themselves credit, making it easier for them to get the money that they need so that people can start spending and saving without fear. This allows the whole economy to stabilize until whatever difficulty was causing issues passes and everything goes back to normal like it had been before.
Why Do Governments Use This Method? Many times, banks need to be able to give out loans in order to get revenue. Why? Because the interest rates are what give them money. If the economy isn’t doing too well, then you will notice that people are not quite as excited to take out loans. Fewer loans mean that the bank is making less money, which makes the economy unstable and causes a variety of issues in regards to all that may be going on. So, governments want to give banks some more cash so that they can give out loans.
Why Does it Matter? If banks aren’t getting a lot of interest from loans, they can’t make money, which means that they can’t give out more loans, which ends up hurting them. So, by allowing the central bank to print money, they can help these banks out and give them just what they need to stabilize, thus allowing them to put out more loans and make some more money, which helps them to thrive as institutions.
