2. The Economics of Foreign Exchange & Rate Drivers
Foreign exchange (Forex) rates fluctuate continuously based on global macroeconomic conditions:
- Central Bank Interest Rates: Higher interest rates set by central banks (Federal Reserve, ECB, Bank of England) attract foreign capital, appreciating the domestic currency.
- Inflation Rate Differentials: Countries with consistently lower inflation rates experience currency purchasing power appreciation over time.
- Current Account Balance: Trade surpluses (exports exceeding imports) increase international demand for a nation's currency.

💡 The Weekend Markup Trap
Global forex markets close from Friday 5 PM EST to Sunday 5 PM EST. To protect against market opening volatility, foreign exchange providers add a 0.5% to 1.5% weekend markup on Saturday and Sunday. Whenever possible, execute currency conversions on weekdays before Friday 5 PM EST.
