Despite the fact that central banks have excellent statistical and data tools to predict accurate results, it is never possible to exactly predict the market nature. Central banks, even though they are powerful, cannot overcome external factors like weather, calamities, political upheavals, etc., to name a few that can cause a significant gap in demand and supply, thereby hurting or boosting market sentiments. Moreover, charting out well-drafted economic plans is not a day's work. It requires data collected over a certain period.
Statistical tools, mathematics and economics can only be effectively applied to data collected over a period of at least 3 to 6 months. Since economics is not an exact science (it is in fact, a blend of human behavior and science), predicting the market with 100 percent accuracy is virtually impossible. Nevertheless, with all the resources at their hands and the expertise of bankers, policy makers and economists, a central bank try to raise the nation's economic power and improve the livelihood of population.
It can be conclusively stated that the monetary policies that are designed and executed by a central bank through the financial institutions operating in the country, do play a role in imparting a stability to the economy. The financial world has faced numerous economic shocks in the last 3-4 years; however, collectively the world economies have been able to recover from it to some extent. It is also important to state here that they still have a long way to go in structuring and mending the global economy.
The Occupy Wall Street campaign reminds us of the striking financial inequality prevalent in all parts of the developed and developing world. Financial inclusion, a long neglected fundamental of a stable economy, must now be at the top of agenda pursued by the monetary policies. Now the question is, "Are central bank behemoths ready with monetary policies to take up the challenge of eliminating the basic flaws in structures of the free-market economies?" Well, only time will tell. Meanwhile, we can keep a close eye on the monetary policies that are in effect, and see how they can force our economic growth.
