Capital flow is simply the movement of money across borders for investment, trade, or production. Think of it as money going on a global adventure! There are two main types:

• Inbound Capital Flow: Money coming into a country.
• Outbound Capital Flow: Money going out of a country.

#Inbound Capital Flow: Attracting Foreign Funds 🧲

• Definition: Foreign investors purchase domestic assets (like stocks, bonds, or interest-bearing accounts).
• Why it happens: Higher real interest rates in a country attract foreign investors seeking better returns.
• Example: A Japanese investor buys U.S. Treasury bonds because they offer a higher interest rate than similar bonds in Japan.
• Impact: Increases demand for the domestic currency and increases the supply of loanable funds.

#Outbound Capital Flow: Investing Abroad ✈️

• Definition: Domestic investors purchase foreign assets.
