Oil price is a vital financial aspect directing the economy in the global world. Changes in the level of oil prices may affect the whole economy; at the same time economic developments may affect the oil prices. For example, while lower oil prices could inhibit financial development and spoil economic and political stability, higher oil prices could cause an increase in inflation and a recession in an economy. Sharp decreases and increases in oil prices have been notable in recent years. These fluctuations in oil prices become one of the key indicators in macroeconomics. Therefore, it is of utmost importance to analyze fluctuations in oil prices. The purpose of this study is to estimate the duration that is the maximum drawdown of highest possible drop in the oil prices. Maximum drawdown can be defined as the indication of the highest possible market risk in finance. In order to detect the maximum drawdown, super-cycles which are specified as total of an upward and a downward movement are determined in the data set which is the oil prices collected between the year 1948 and 2018. This is done by using filtering methods such as Hodrick-Prescott and Band Pass filter. Fractional Brownian motion process is used for modeling the oil prices since the increments are observed to be dependent. We have conducted simulation studies for calculating the expected value of the maximum drawdown and expected value of the duration of the maximum drawdown. In this study, comparison of simulation results and observed results from the real life data set is provided in order to make prediction and give discussion on the duration of the maximum drawdown of the oil prices.

The Relation between crude oil prices and financial market indicators: a copula approach
Öztürk, Derya Ezgi; Kestel, Sevtap Ayşe; Küçüközmen, Coşkun; Department of Financial Mathematics (2014)
Oil prices have far reaching effects on the economy and financial markets since oil market is one of the most important markets in the world due to its crucial role of oil within economic activity. Although most of the economies are expected to be affected by the changes of oil prices, the magnitude of the effects may change from country to country. Oil-export/import dependent countries are expected to be more open to impacts arousing from changes in oil prices. Turkey, as a heavily oil importing country, i...
Review of natural gas discovery and production from conventional resources in Turkey
Keskin, Hakan; Mehmetoğlu, Mustafa Tanju; Department of Petroleum and Natural Gas Engineering (2007)
Oil and natural gas are the most strategic raw materials to meet the expanding energy requirement in today’s world. They have great impact on issues such as economy, national security, development, competition, and political consistency. Being a developing country, Turkey’s natural gas requirement is increasing rapidly. However, the production is far from covering the demand. Recent assumptions point out that natural gas demand of Turkey will reach 44 billion cubic meters in 2010 with a financial burden of ...
Drivers of the oil price : an empirical analysis of the effect of oil imports by OECD regions
Güneyligil, Ümmügülsüm; Akbostancı Özkazanç, Elif; Department of Economics (2013)
This study analyzes the effect of oil imports by OECD regions on crude oil price by using Kaufmann’s price rule as a benchmark. Using the autoregressive distributed lag (ARDL) cointegration approach; it is found that there is cointegration between crude oil prices, days of forward consumption of OECD crude oil stocks, OPEC quota, OPEC cheat and key variables imported crude oil by OECD. However, ARDL based error correction models (ECM) indicate that regional factors are not a significant determinant of crude...
The Effects of exchange rates, oil prices, global risk perceptions and global warming on food prices
Dağdelen, Derya; Soytaş, Uğur; Department of Business Administration (2012)
This thesis examines the relationship between food prices, oil prices, carbon emission prices, exchange rates and global risk perception. To obtain the effects of these variables on the food prices, Toda and Yamamoto procedure is employed for 5-day week daily time series covering the period February 27, 2008 and March 21, 2011. The empirical results indicate that only volatility index Granger causes food prices. Furthermore, according to results of generalized impulse response plots food prices respond to a...
Critical evaluation of the energy resources of Turkey with respect to the world prospects
Aydemir, Mehmet Olcay; Mehmetoğlu, Mustafa Tanju; Department of Petroleum and Natural Gas Engineering (2010)
Existing petroleum and natural gas reserves, which are the major supplies of primary energy demand of the world, are cumulated in a few countries. This causes a serious supply security problem for many countries. On the other side, greenhouse gas emissions caused by mainly fossil fuels are gradually increasing to a point which jeopardizes the future of the earth. By now, countries have to consider both their supply security and this global environmental problem while planning their energy future. For Turkey...
