The modern global currency system aims to prevent currency crises and assist in case they occur. It operates based on international laws, adjusting currency values and combining elements of supernational and private law. Official foreign reserves play a crucial role in providing international liquidity, stabilizing currency value, and supporting currency exchange policies. Countries with leading positions in the global economy and liberal currency legislation are expected to actively use their currency reserves in financial operations. Maintaining currency stability is essential to prevent depreciation of reserves and ensure stability at both national and global levels.
