============================================
Lets start with the very beginning.
It is essential to understand the problem before we can find a solution.
Everyone knows that a bubble has burst in the world economy.
2000 had seen the IT bubble burst.
*** So what was this bubble about?
Many people would say it was a real-estate bubble or bad-debt bubble.
The truth is that it was something much bigger much more sinister than that.
It was an
assets bubble.
This bubble was very different from most of the other bubbles that the world economy has seen in its recent history.
It was a bubble where money was losing value and assets were gaining value.
Think of any asset that you can - debt instruments, real estate, crude oil, gold, stocks, food etc. Most assets had seen significant price appreciation before the bubble burst.
Why were the prices of these assets going up?
because money was losing its value.
When money loses its value, prices go up.
This is what we call inflation.
The world had trapped itself in a financial system where it made no sense to hold cash. No one wanted to hold cash and people started buying all sorts of assets.
but why did it happen?
============================================
*** So why did we have as "assets bubble"?
It is common knowledge that excessive money supply causes inflation.
When there is a lot of money in the financial systems, price of goods/assets go up.
For years, central banks around the world had kept their monetary policies loose. Interest rate were kept low and government deficits were allowed to grow beyond reasonable limits. (This is true especially for US and a few EU economies).
but excessive money supply was not the only cause of this bubble.
There were two more reasons:
excessive leverage - In the last few years, dozens of different financial instruments had been come into prominence which allowed companies to create assets much bigger that their actual capital.
A good example of this would be
mortgage-backed securities.
Multiple mortgage loans were bundled up as one single instrument and were sold-off to investors. This freed capital for banks and allowed them to give more loans. Thus, banks ended up with assets and liabilities much bigger than their own capital.
excessive risk - Excessive money supply and excessive leverage resulted in excess of money in hands of the lenders. When these lenders couldn't find reliable borrowers, they started lending to anyone who wanted a loan.
Thus, emerged the sub-prime crisis. (It must be noted that the sub-prime problem is not limited to real-estate. It even exists in credit cards, personal loans, corporate loans etc. It is just a matter of time before these get exposed too).
