Here is another post that I just realized I hadn't actually 'posted'...
I wanted to discuss something you may have read about in the news over the past few years; the US housing market. Many economists consider the health of the housing market the most important factor to the overall health of the economy. Recently, the US Federal Reserve has taken steps to keep mortgage rates very low, by buy long-term government bonds. The process is called quantitative easing. I will do my best to first explain why the U.S. would do this and how it is supposed to help the economy recover.
Mortgage Lending
To start, we need to take a look at the process of bank lending for mortgages. When you go to the bank to get a mortgage for your house, the bank will lend you that money at a certain rate. This rate isn't an arbitrary number that they pull out of the air, however. It is based on the rate that the bank can borrow the funds from the central bank (the federal reserve in the US) in order to lend to you. The bank makes its profit by making the rate they charge you higher than the one they have to pay the central bank.
For example, let's say you bought a house and need to borrow $200,000. You want some security on your interest rate, so you decide to get a 5-year fixed rate mortgage at 4% interest. That means that the bank will lend you the money for 5 years and guarantee you will pay a rate of 4% to the bank. So, the bank now needs to come up with $200,000. They go to the Central Bank and ask for a 5-year loan. The central bank posts their lending rates and in this case, they are lending for, say, 1.5% for 5-year paper. So the difference is 4% - 1.5% = 2.5% which is the profit for the bank. 2.5% per year x $200,000 x 5 years = about $25,000 (excluding compounding)... nice to be a bank...
House Prices
As you can imagine, the easier it is to get a mortage, the easier it would be to buy a house. If rates were 0%, in theory we could keep borrowing money and buying property, as long as our credit was good enough. That's why in times of very low interest rates, house prices tend to rise. More people can afford the lower mortgage payments that go along with low interest rates.
That's what happened in the US about 8 years ago. In an effort to stimulate the economy, the Federal Reserve decided to cut interest rates to near-record lows, which made it easier to borrow money. Everyone borrowed money. Some people even borrowed enough money to buy multiple houses. Why not? It was a self-fulfilling prophecy; the cheaper the money, the more the value of your house increased. If your house increased in value, you could re-finance your mortgage and borrow more to buy another house. This demand for houses then fuelled the continued increase in house prices.
As the economy improved, inflation crept back into the system. Unemployment was nice and low. This usually spells time for the government to increase interest rates again, to make sure inflation doesn't continue to rise. When this started to happen in 2006, people would then go to refinance their mortgages and realize that they would not be able to afford the payments. Instead of getting that 5-year fixed rate mortgage at 4%, it was now costing them 7% or more. They realized they would have to sell their house. This lead to a large decline in house prices, as many people began downsizing into houses they could afford. This had a domino effect. It meant that there was less demand for new homes being built, which lead to more workers getting laid off, which lead to higher unemployment. Never mind that the banks nearly overrode the entire financial system in 2008. That's fodder for another post.
The Role of the Fed
When this happened, the US Federal Reserve cut rates literally to 0%. But banks were still being very cautious about lending money. So the next step is quantitative easing. This is when the Fed literally turns on the printing press and starts printing new money for the system. They use this money to buy US long-term bonds, which has the effect of lowering the yield on the bonds. So when banks lend mortgage money and need to borrow government money, the interest they pay will be even lower. That means the interest we pay to get a mortgage will be lower as well, which in theory should create demand for housing again.
It has taken a while but this process seems to be finally working. House prices south of our border are slowly creeping higher, as more people are realizing they can afford a new mortgage. Hopefully this continues, as it will mean more jobs in the housing sector, which should mean more jobs elsewhere.
The Risks
The main risk of quantitative easing is that by continuously printing money, you are lowering the value of the money in the system, which could lead to hard goods costing more - this is inflation. The hope is that as the economy improves, the Fed will be able to reverse the process. They can sell the bonds they've bought, which will slowly cause long-term yields to rise again... which SHOULD put a slow-down on inflation. We shall see how this chess match plays out.
That is all. Hopefully you have somewhat of an understanding of quantitative easing (QE) now. Thanks for reading my post.
