Physical settlement is a fundamental concept in the world of options trading, representing the tangible exchange of the underlying asset when an options contract is exercised or reaches its expiry. Instead of a monetary payment to settle the contract, the buyer of a call option receives the actual shares or commodity, and the seller of a put option is obligated to purchase the actual shares or commodity. This mechanism stands in contrast to cash settlement, where the difference in value is simply paid out in cash.
Understanding physical settlement is crucial for anyone trading options, particularly for those holding positions until expiry. It directly impacts your account's holdings and liquidity. For example, if you are short a call option that is in the money at expiration, you will be obligated to deliver the underlying shares. If you don't own them, you'll need to buy them in the open market, which can incur significant costs and risks, especially if the price has moved unfavorably. Conversely, if you are short a put option that is in the money, you will be obligated to buy the underlying shares, potentially leaving you with a stock you didn't initially intend to own. This highlights why managing assignment risk and understanding your obligations are paramount when dealing with physically settled options. For strategies like a cash-secured put, the physical settlement aspect means you must be prepared to have the cash to buy the shares.
If you are assigned on a physically settled call, you must deliver the underlying shares. If you are assigned on a put, you must purchase the underlying shares.
Not necessarily. If you wanted to acquire or dispose of the underlying asset at the strike price, physical settlement can be a desired outcome, provided you planned for it.
