Oil is main source of energy and it impacts all sectors of economy through its backward and forward linkages.

1.  The most direct impact comes to road transportation, sea transportation and Air transportation sector through increased fare.

2.  Another impact is increased cost of electricity where oil is used to produce electricity through oil based power plant or generator.

Because most of the global economy is reliant upon the money that comes from oil and gas, and because the United States Dollar is directly tied to the Saudi Riyal, all sectors are majorly affected by the change in oil prices. However, what you now have is a decline in job positions in the Western societies and a downsizing of companies in the Middle East. What's happening is now that there's a decline in oil and gas purchasing, the power lies in the hands of the Middle East and they are not decreasing salaries, job positions within any single given company, and they are turning to Nationalism...which - in my honest and unbiased opinion - is best for everyone considering all of the factors.
