What is going on to the global financial market? This probably is the question being asked most frequently in the mean time. I am not an Scientific Trading Machine  economist. But I do really concern about the current financial crisis and the economy like the other people. I want to understand the current situation. I want to see the complete picture. Therefore, I try to understand and analysis the whole event in a simplified way, and prepare to express my idea in laymen text.

In the society, reasonably, trades among people are negotiated by the participants as a fair exchange of goods and services. However, it is not easy to match the same values of different goods and services every time. Therefore, money appeared. What is money? It is a recognized medium of exchange, agreed by all the participants. In other words, it is an IOU or a credit for the seller and a debt for the buyer. For example, A sells goods in the market. When B comes to buy the goods from A, B gives an IOU to A as an exchange. With that IOU, A can buy goods back from B or other parties with the equal value. The IOU is the money. It gives people a flexible way in trading.
