JASDEC settlement operations

Wiki route

This entry sits under banking index as a settlement-infrastructure companion to JASDEC entity page and JSCC clearing corp. Use it with Master Trust Bank operating model, Custody Bank operating model, Japan master trust and custody bank landscape, trust-bank custody operating comparison, and Japan market infrastructure map.

TL;DR

JASDEC (株式会社証券保管振替機構 / Japan Securities Depository Center, Inc.) operates book-entry systems for shares and related instruments, corporate bonds, short-term corporate bonds, and investment trusts; a pre-settlement matching system; custody services for eligible foreign stock certificates; and other settlement services listed in its official company outline. JGBs use the separate Bank of Japan JGB Book-Entry System. JASDEC and its wholly owned subsidiary JDCC must also be kept distinct: JDCC is the financial-instruments clearing organization for JASDEC’s DVP service for non-exchange transaction deliveries (NETDs). ^[Sources: https://www.jasdec.com/en/about/office/outline/; https://www.jasdec.com/en/about/jdcc/outline/; https://www.boj.or.jp/en/paym/jgb_bes/index.htm.]

1. Entity and legal-operating perimeter

Sources: identity, dates, capital, address, and the business inventory come from the current JASDEC and JDCC company outlines; historical succession comes from JASDEC’s official history. ^[Sources: https://www.jasdec.com/en/about/office/outline/; https://www.jasdec.com/en/about/office/history/; https://www.jasdec.com/en/about/jdcc/outline/.]

2. System map

Sources: each row is scoped to the corresponding official system page; JGB separation is supported by the BoJ’s own system page. ^[Sources: https://www.jasdec.com/en/system/less/; https://www.jasdec.com/en/system/sb/; https://www.jasdec.com/en/system/cp/outline/feature/; https://www.jasdec.com/en/system/fund/outline/basic/index.html; https://www.jasdec.com/en/system/finance/outline/range/; https://www.jasdec.com/en/system/dvp/outline/; https://www.jasdec.com/en/system/foreign/outline/; https://www.boj.or.jp/en/paym/jgb_bes/index.htm.]

3. Participant vocabulary

Sources: terminology follows JASDEC’s official shares-system structure and NETD DVP eligibility descriptions. A bank, trust bank, securities firm, or global custodian must not be called a direct participant without checking the current service-specific list. ^[Sources: https://www.jasdec.com/en/system/less/outline/organization/; https://www.jasdec.com/en/faq/.]

4. Clearing, matching, securities settlement, and cash settlement

Sources: this table separates functions that older summaries often conflate. The exact clearing and funds route must be read from JSCC, JDCC, JASDEC, and BoJ materials for the relevant product and transaction type. ^[Sources: https://www.jasdec.com/en/system/finance/outline/range/; https://www.jasdec.com/en/system/dvp/outline/; https://www.jasdec.com/en/about/jdcc/outline/; https://www.jpx.co.jp/jscc/en/cash/cash/assumption-obligation/dvp.html; https://www.boj.or.jp/en/paym/jgb_bes/index.htm.]

5. Corrections to avoid

Sources: the correction table is derived from the operator boundaries and current rule/fee inventories. It intentionally avoids extending one service’s rules to another. ^[Sources: https://www.jasdec.com/en/rule/business-rules/index.html; https://www.jasdec.com/en/rule/dvp/whole/; https://www.jasdec.com/en/system/; https://www.boj.or.jp/en/paym/jgb_bes/index.htm.]

6. Trust-bank and custody research boundary

Trust banks and other custodians can interact with JASDEC as account-management institutions or participants where admitted under the applicable service. Their exact status is legal-entity and service specific. A “信託口” name in an issuer filing is therefore not enough to prove that the trust bank is the beneficial investor, and a custody mandate is not enough to prove direct JASDEC participation.

For a custody claim, record:

1. the legal entity;
2. the JASDEC system or service;
3. direct versus indirect account-management status;
4. the instrument and transaction type;
5. the clearing operator, if any;
6. the cash-settlement route; and
7. the source date.

Foreign-stock-certificate custody is also a specific JASDEC service: the official page describes use of local custodians, book-entry settlement, rights processing, and corporate-action notification for eligible instruments. It should not be generalized into a universal Euroclear/Clearstream link for every Japanese or foreign security. ^[Source: https://www.jasdec.com/en/system/foreign/outline/.]
