Positive Convexity

Positive convexity exists when the price of an asset increases at an increasing rate as interest rates fall, and decreases at a decreasing rate as interest rates rise. This creates a price-yield profile that is curved upward, providing a buffer against interest rate volatility.

Investors generally prefer positive convexity because it leads to better performance when rates move in their favor and less severe losses when rates move against them. In options trading, positive convexity is often associated with long option positions, where the gamma provides this beneficial curvature.

It is a desirable property for portfolio managers seeking to limit downside risk while maintaining upside potential. Understanding the source of convexity helps traders optimize their portfolios for different interest rate environments.

In the crypto market, protocols that exhibit positive convexity are often more resilient to market shocks. By intentionally incorporating positive convexity, investors can build more robust strategies that perform well even when market conditions become turbulent.

It is a key aspect of sophisticated risk management and derivative structuring.
