The Relationship between the US Dollar Index (DXY) and Market Sentiment
The US Dollar Index (DXY) measures the relative strength of the US dollar against a basket of major international currencies (such as the Euro, Japanese Yen, British Pound, etc.).
Why does DXY reflect "Fear"?
In the global financial system, the US dollar is the ultimate liquidity and safe-haven asset ("Cash is King"). When the global economy faces severe recession risks, geopolitical crises break out, or the Federal Reserve unexpectedly hikes interest rates causing liquidity crunches, global capital frantically buys US dollars for safety, causing the DXY to soar.
Therefore, for the stock market, emerging markets, and cryptocurrencies (like Bitcoin), a strong dollar is often poison. The DXY typically has a high negative correlation with most risk assets.
Our Assessment Criteria
Historically, the DXY's comfortable range has been roughly between 90 and 105:
- < 95: Extreme Greed. A weak dollar implies abundant global liquidity, leading to surging risk assets.
- > 103: Fear starts to spread.
- > 105: Extreme Fear. This usually means the world is facing some sort of dollar liquidity crisis or an extremely severe macroeconomic environment.
