Bid-Ask Spread Efficiency

The bid-ask spread is the difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept for an asset. Efficiency in this spread indicates that the market is competitive and that price discovery is functioning effectively.

A narrow spread suggests high liquidity and low transaction costs, which are hallmarks of a mature market. Conversely, wide spreads often signal low trading activity, high uncertainty, or significant information asymmetry between participants.

In crypto markets, tightening spreads over time often correlate with the integration of professional high-frequency trading firms. This efficiency allows for more accurate pricing of derivative contracts and improves the overall cost-effectiveness of trading strategies.
