Physical vs cash-settled options: shares or cash
Compare physically settled and cash-settled options by deliverable, settlement amount, assignment, expiration, multiplier, portfolio impact, and contract risk.

Direct answer
Physical settlement transfers the contract's deliverable, commonly shares, after exercise or assignment. Cash settlement transfers money based on the difference between the official settlement value and strike, multiplied by the contract multiplier. Neither label determines exercise style, last trading day, or settlement timestamp; those are separate contract terms.
Physical settlement creates an underlying position
For a standard equity call, exercise commonly buys the specified shares at K and assignment makes the writer deliver them. A put exercise commonly sells shares at K and assignment makes the writer buy them. Adjusted contracts may deliver a nonstandard share count, cash, or other components.
The option disappears, but the resulting shares, purchase cash, short-stock possibility, dividends, and market exposure remain. Verify the deliverable rather than assuming every contract represents exactly 100 ordinary shares.
Cash settlement converts intrinsic value into money
For a cash-settled call, a simplified settlement amount is max(V - K, 0) × M, where V is the official settlement value and M is the multiplier. A put uses max(K - V, 0) × M. No shares are delivered.
If V is 4,025, K is 4,000, and M is 100, the call settlement amount is 2,500 before fees and adjustments. V may be a specially calculated index value rather than the visible spot quote.
Portfolio consequences differ after expiration
Physical assignment can sell a covered position, buy unwanted shares, or create short shares. Cash settlement avoids those inventory changes, but a large debit can still consume buying power and a hedge can disappear while the portfolio it protected remains.
Cash settlement also creates basis risk when the option references an index but the portfolio holds an ETF or different basket. Similar price movements do not guarantee an exact hedge.
Read the complete specification before trading
Settlement type does not reveal whether exercise is American or European, whether settlement is AM or PM, when trading stops, or which price defines V. Product families can contain different series.
Record the exact symbol, series, multiplier, deliverable, exercise style, last trading day, settlement calculation, payment date, broker cutoff, and tax treatment. The option-chain label alone is insufficient.
Common questions
What is the difference between physical and cash settlement?
Physical settlement fulfills exercise or assignment by transferring the contract deliverable, usually shares for standard equity and ETF options. Cash settlement instead debits and credits an amount based on intrinsic value at an official settlement value and the contract multiplier. The option position ends in both cases, but physical settlement leaves an underlying position while cash settlement leaves only the resulting cash flow.
Do cash-settled options deliver any shares?
No shares are delivered under a cash-settled contract. An in-the-money amount is converted to cash according to the product's settlement formula, while an out-of-the-money contract has no intrinsic settlement amount. The official value can differ from the last visible index quote, and the cash debit or credit can still be large enough to affect buying power and portfolio risk.
Are all index options cash settled and European style?
Many broad-based index options are cash settled and European style, but investors should not generalize without reading the exact product and series specification. Exercise style and settlement method are separate terms, and some product families contain exceptions or multiple settlement series. Confirm the root symbol, contract multiplier, AM or PM calculation, last trading day, and official settlement-value symbol.
Can physical settlement create an unexpected stock position?
Yes. A short put assignment can buy shares, a short call assignment can create or deliver short shares when no covered stock exists, and long-option exercise can also produce shares or short stock. Adjusted contracts may have unusual deliverables. Closing before expiration reduces this uncertainty only when the order actually fills; a pending order does not alter the contract's settlement obligation.
