How does the yield curve signal predict crypto performance?
A steepening yield curve (positive 10Y-2Y spread widening) signals economic expansion and risk-on sentiment, historically bullish for crypto. An inverted yield curve signals recession risk, historically bearish. Octodamus tracks T10Y2Y via FRED in real-time.
