Why is Federal bank hiking the interest rates now?

The 2008 recession has hit the world so high and especially the United States. The housing and financial firms has to see a lot of problems and impact is seen on almost everything. Federal bank which has to control the situation started to give the funds to the firms which effected with recession but are trust worthy at zero marginal interest rates. These funds are suggested to use for employment creativity and encourage international markets which were effected. The firm investors who got the money started to invest them in markets like India and china which were less affected by the recession. These countries stock markets has given them the best results and investors started to enjoy the benefits. It has been 7 years to the recession, Federal bank understood that there aren’t much problems as the unemployment index is at 5% in USA and decided to stop the free money flow into the country by imposing some interests. So as the money is now coming for interest the investors are taking back the investments from the international markets and started paying off back to federal markets (it is said more than 15,000 crore rupees of foreign money is taken back in September-16). This is why the stock markets of India and China are collapsing.
