How to compute spot exchange rate?
Can you please explain the process of calculating the spot exchange rate in detail? I'm particularly interested in understanding how the market demand and supply factors are taken into account, and if there are any specific formulas or tools used to arrive at this rate. Additionally, how do changes in economic conditions and geopolitical events impact the spot exchange rate, and what role do central banks play in influencing it? I'm looking for a comprehensive yet concise explanation that will help me grasp the concept better.
