Does Basis Risk Increase or Decrease as the Time to Expiration Shortens?

Basis risk generally increases as the time to expiration shortens, especially if the hedge is meant to cover a period beyond the option's expiry. This is because the option's delta, or sensitivity to the underlying price, can become volatile near expiry, and the potential for a large price divergence between the option and the underlying asset increases.
