Korea Investment’s unpaid-settlement FAQ explained
Selling shares before their purchase-payment date does not, by itself, show that the purchase has been paid. In Korea Investment’s next-day-sale example, the purchase payment falls on T+2, but the sale money arrives on T+3. Here, T is the original purchase. Korea Investment FAQ
The useful distinction is between making a sale and receiving its proceeds. The provider’s FAQ is undated, so this guide explains its example and restrictions rather than setting today’s deadlines for your account.
Follow the purchase payment and the sale receipt separately
The FAQ describes a purchase followed by a sale the next day. Both payment dates are measured from the original purchase, not from a new T starting at the sale.
Korea Investment’s next-day-sale example
| Transaction | T | T+1 | T+2 | T+3 |
|---|---|---|---|---|
| Original purchase | Shares bought | — | Purchase payment due | — |
| Next-day sale | — | Shares sold | — | Sale proceeds received |
T is the original purchase. These markers reproduce the FAQ’s example, not a calendar deadline for a current account. The two rows keep the purchase obligation separate from the later sale receipt.
The sale has already happened when the purchase payment comes due, but its money arrives later in this example. The sale receipt therefore cannot be treated as cash received by the earlier payment date. That timing gap matters if there is not enough actual cash to settle the purchase. Korea Investment FAQ
A same-day sale still depends on sufficient settlement cash
The same-day case is different. The FAQ says that selling on the purchase day does not lead to the restriction when settlement completes normally. Its worked example also shows that a sale at a loss need not leave an unpaid amount when cash already in the account covers the difference.
For this question, the important point is whether sufficient cash and proceeds actually settle. “I sold before settlement” and “I sold at a loss” are not enough on their own to establish a shortfall. Nor does an early sale automatically remove one. Korea Investment FAQ
Read both cash restrictions together
The Korean label 미수동결 refers here to the provider’s unpaid-settlement restriction. Its phrase 현금 100% 위탁증거금 describes a full cash order-margin or deposit requirement: cash equal to 100% of the purchase amount must be provided for a buy order. The 100% figure is not a commission fee.
This is not a blanket ban on every trade. But the FAQ also restricts cash repurchases using the resale amount until the unpaid balance, measured on a settlement basis, has been resolved—even after the sale has executed. Keep that condition alongside the full-cash requirement. Korea Investment FAQ
| Condition in the FAQ | What it means in this explanation |
|---|---|
| Full cash order-margin or deposit requirement | A buy order requires cash equal to 100% of the purchase amount. This is a funding condition, not a commission charge. |
| Unresolved settlement-basis unpaid balance | Cash repurchase using the resale amount remains restricted until that balance is resolved, even after a sale executes. |
These are linked conditions in the provider’s FAQ, not confirmation that a particular order will be accepted.
If you are comparing the term with futures margin, see how futures margin differs from leverage. That is a separate topic; it does not determine Korea Investment’s cash-stock restrictions.
Questions about the FAQ
Does selling the next day mean the original purchase is already paid?
No. In the FAQ’s example, the original purchase payment is due at T+2 and the next-day sale money is received at T+3. An executed sale is not evidence that its proceeds have arrived in time for the earlier payment.
Does T+3 mean every stock sale takes three days to settle?
No. T+3 is measured from the original purchase in this example. The sale itself occurs at T+1. These dates do not establish a universal sale-settlement cycle or show that a market-wide timetable has changed.
Does the freeze label mean I cannot trade at all?
The FAQ describes a full cash order-margin requirement rather than a complete trading ban. It also says cash repurchase using the resale amount remains restricted while the settlement-basis unpaid balance is unresolved. A completed sale alone does not remove that condition.
Can this FAQ tell me how long a restriction will last today?
Not reliably on its own. It has no observed update date and includes historical implementation wording from 2007. For an actual account, ask the provider which current conditions apply to the unpaid balance and order you are asking about. This explanation does not establish a current duration, exception threshold or account-specific deadline.
