  Banks as fund intermediaries in providing and allocating resources to the community, encounter market risk, liquidity risk and etc. In this study, the market risk, is taken into consideration in order to determine the optimal currency basket, one of the fundamental aspects of Foreign Currency Reserve Management in banks, which itself is also affected by fluctuating interest rates, exchange rates, stock prices and etc. The approach used in this paper is the value-at-risk criterion (VaR) the variance-covariance method, along with the exponentially weighted moving average (EWMA) technic. Value at risk actually summarizes the types of risks in a single digit, and it releases the senior management from bunches of risk calculations. The purpose is to design a model which provide an optimal combination for holding 6 currency reserves such as U.S. dollar, Dirham, Yen, Lira, Won, and Euro in Bank Mellat using the reference rates data of the aforementioned currencies in 2018. At the end, the model was solved using LINGO and Excel software. The results show that the maximum share of the US dollar and the dirhams in the currency basket of Bank Mellat are 33% and 67%, respectively. Accordingly, if the share of that currencies mentioned above exceed the obtained digits in the currency basket, then the maximum expected losses on the currency portfolio increase over the time and at the level of desired level of confidence. Also, other currencies are so risky, therefore Mellat Bank, to hold these currencies must plan more based on its trading needs. Manuscript profile

  One of key aspects of foreign reserves management in central banks is to determine appropriate currency portfolio of foreign exchange reserves. In this study, optimal currency composition of four major reserve currency (including dollar, euro, pound and yen) in currency portfolio of the central bank of Iran analyzed. For this purpose, post modern portfolio approach and quarterly data during 2011 to 2014 used and efficient frontier of the central bank extracted as well. The results indicate that maximum share of dollar, euro and yen in the strategic currency reserves portfolio of the central bank is respectively 35, 29 and 48 percent. Accordingly, if share of the currencies in the currency portfolio was more than these figures, the value of reserves is reduced. Furthermore, pound is a risky currency, so the central bank to hold the currency, mainly should act based on his transaction needs. Manuscript profile
