Why do bid-ask spreads widen?

Bid-ask spreads widen when market makers face greater uncertainty, inventory risk or difficulty hedging a position.

SHORT ANSWER

The core idea

Bid-ask spreads widen when market makers face greater uncertainty, inventory risk or difficulty hedging a position.

THE MECHANISM

What is happening underneath

Lower trading activity and stressed funding conditions can amplify the effect.

MARKET INTERPRETATION

How investors should read it

A wider bid-ask spread is effectively a higher transaction cost and a direct sign of weaker liquidity.

BONDSTATS TAKEAWAY

The same market move can carry different information depending on which maturity, issuer and risk premium is changing. Read the question together with the underlying concepts rather than treating one price move as a universal signal.
