๐ŸŒ 1. What Is a Currency?

A currency is more than paper money ๐Ÿ’ต. It is:

A unit of value ๐Ÿ“

A medium of exchange ๐Ÿ”„

A store of wealth ๐Ÿฆ

Without trusted currencies, trade collapses โš ๏ธ.

US Dollar (USD) ๐Ÿ’ต

Euro (EUR) ๐Ÿ’ถ

Chinese Yuan (CNY) ๐Ÿ’ด

Japanese Yen (JPY) ๐Ÿ’ด

British Pound (GBP) ๐Ÿ’ท

๐Ÿ’ต 2. The US Dollar: King of Global Money

Oil is priced in USD ๐Ÿ›ข๏ธ

Global trade settles in USD ๐Ÿšข

Central banks hold USD reserves ๐Ÿฆ

Over 60% of global reserves are in dollars ๐Ÿ’ฑ.

๐Ÿ“Œ Result: When the dollar rises ๐Ÿ“ˆ, global liquidity tightens ๐ŸŒโš ๏ธ.

Investment ๐Ÿ’ผ

Consumption ๐Ÿ›๏ธ

Rate changes:

Higher rates ๐Ÿ“ˆ โ†’ slow economy ๐Ÿข
