South Korea’s financial investment industry, related institutions and individual investors broadly support shortening the domestic securities settlement cycle from T+2 to T+1, but participants at a Korea Financial Investment Association discussion urged extensive preparation before implementation. The change would let investors withdraw stock-sale proceeds one day earlier, while accelerating purchase payments and related schedules. Back-office processes including trade corrections, clearing and netting, tax processing, trade confirmations and settlement instructions would also need to move forward. Foreign investors face particular challenges because of time-zone differences, foreign-exchange arrangements and the possibility that Asian and European markets could transition around the same time, increasing infrastructure costs. Participants said all market institutions, including the Korea Securities Depository, Bank of Korea, Securities Finance and Korea Exchange, must upgrade systems and coordinate implementation. They also called for contingency measures because shorter adjustment windows could raise operational settlement failures; the Korea Capital Market Institute cited a 2%-3% settlement-failure frequency in the United States. Korea Exchange has previously said it would prepare an October roadmap covering regulatory reforms, system upgrades, phased implementation and testing, without fixing a launch date.
