The Philippines was already experiencing one of its worst years when the severe developments of the third quarter compounded the problems . The "second oil crisis" of 1979 not only increased the price of a major import, but also brought about recessionary conditions in the OECD countries and thereby falling prices and little quantitative growth for Philippine exports. The second oil crisis, triggered by the Iranian revolution in 1979 and exacerbated by Iran-Iraq war, resulted in a sudden and substantial increase in global oil prices that cause result faces challenge for Philippines. This study aims to investigate the effects of the second oil crisis. 1. What are the causes of oil crisis in the Philippines? 2. How does war affect the economy of the Philippines? 3. How does the leadership of former president Marcos affect the economic growth of the Philippines in year 1970s to 1980s? The Philippines' economic expansion was significantly impacted by the second oil crisis in the late 1970s and early 1980s. It was primarily brought on by an increase in oil prices on a global scale that was brought on by geopolitical events like the Iran-Iraq War and the Iranian Revolution. The Philippines, who rely significantly on oil imports for both transportation and electricity, were immediately confronted with the problems of inflation, declining consumer purchasing power, and rising production costs. To comprehend the roots of the Philippine economic crisis, it is crucial to examine various historical, political, social, and economic factors that have contributed to its complex economic landscape. The roots of the Philippines' economic troubles in the early to mid-1980s can be attributed to a combination of economic mismanagement, external factors, and political instability. Global Oil Price Shock OPEC Actions External Trade Troubles Slower Economic Growth Government's Response To mitigate the economic effects of the second oil crisis, the Philippine government should implement the following solutions: 1. Invest in renewable energy sources such as solar, wind, and geothermal power to reduce dependence on imported oil. 2. The government should do a comprehensive feasibility study about nuclear energy. 3. Promote sustainable economic growth that is not dependent on elevated levels of debt. 1. Provide financial assistance to public transportation providers to help them offset the rising cost of fuel. 2. Revive the Bataan Nuclear Power Plant 3. Invest in research and development of renewable energy technologies. The Philippines was heavily impacted by the second oil crisis in the late 1970s and early 1980s, which was caused by worldwide oil price increases owing to geopolitical tensions. Inflation and economic issues resulted from the country's reliance on oil imports. To counteract the situation, the government enacted energy conservation policies, imposed gasoline price caps, and made investments in alternative energy sources and infrastructure. These steps not only solved immediate concerns but also increased the Philippines' energy selfsufficiency and resilience, lowering its dependency on foreign oil.
