How does speculation in currency markets impact a country's monetary policy under a flexible exchange rate system?

Speculation in currency markets refers to the buying and selling of currencies based on predictions about their future values. In a flexible exchange rate system, where currency values can change freely based on supply and demand, this speculation can significantly impact a country's monetary policy. For example, if traders believe that a country's economy will weaken, they might sell that country's currency, causing its value to drop. This depreciation can lead to higher inflation, prompting the central bank to raise interest rates to stabilize the economy. Therefore, central banks must consider these speculative activities when making decisions about interest rates and other monetary policies to keep the economy balanced.
