Government and Central Banks
Central banks have greater control over fiat currency, allowing them to combat inflation or stimulate growth through quantitative easing and adjusting interest rates.
They can control the monetary supply by adjusting interest rates, with lower rates making loans cheaper and boosting investments and consumer spending.
Central banks also buy or sell government bonds to control money supply, injecting money into the economy by buying bonds and pulling money out by selling them.
This flexibility in currency valuation can lead to countries intentionally devaluing their currencies to gain trade advantages, potentially leading to currency wars and fluctuations in exchange rates.
Central banks can stabilize the currency and maintain economic growth by using monetary policy tools, such as adjusting interest rates and buying or selling government bonds.
