# 日証金信託銀行 (JSF Trust and Banking)

## Wiki route

JSF Trust and Banking is the trust-bank subsidiary route for [[financial-regulators/japan-securities-finance|Japan Securities Finance]]. Read it with [[securities/japan-margin-trading-and-securities-finance|margin trading / securities finance]], [[securities/japan-stock-lending-market-route|stock lending]], [[securities/japan-market-infrastructure-map|Japan market infrastructure]], and [[banking/japan-trust-bank-custody-map|trust-bank custody map]].

Use this page when the question is about client asset protection trusts, margin / collateral trust structures, securities-market plumbing, crypto-asset deposit trust, or security-token cash / asset administration.

## Overview

日証金信託銀行株式会社 is a specialist trust bank wholly owned by [[financial-regulators/japan-securities-finance|Japan Securities Finance]]. Its official company profile lists the bank as founded in 1998, capitalized at 14.0 billion yen, and owned 100% by JSF.

The bank deserves a standalone page because its trust functions are tightly connected to securities-market infrastructure. Its public history includes customer asset protection trust, securities trust, FX margin trust, derivatives / CFD margin trust, crypto-asset deposit trust, and security-token-related trust handling.

| Item | Reading |
|---|---|
| Legal name | 日証金信託銀行株式会社 |
| English name | JSF Trust and Banking Co., Ltd. |
| Parent | [[financial-regulators/japan-securities-finance|Japan Securities Finance]] 100% |
| Founded | 1998-11-17 |
| Capital | 14.0 billion yen |
| Bank / branch code | 0321 / 001 in official company profile |
| Core route | Specialist trust bank for securities / financial-operator trust needs |

This is not a retail trust-bank story like inheritance / wealth channels at a full-service trust bank. The stronger reading is "regulated trust layer for market participants."

## Business Line Map

| Trust function | Public relevance |
|---|---|
| Customer asset protection trust | Helps financial instruments business operators segregate customer assets. |
| Securities trust | Links trust-bank structure to securities holdings and administration. |
| FX / CFD margin trust | Places customer margin protection inside a trust wrapper. |
| Debt assumption / collateral trust | Supports structured obligations and risk-transfer mechanics. |
| Crypto-asset deposit trust | Connects crypto-asset operator protection needs with trust-bank administration. |
| Security-token trust | Creates a bridge from digital securities to trust-account administration. |

These functions connect [[financial-regulators/japan-securities-finance|JSF]], [[securities/financial-instruments-business-operators-japan-index|FIEA operators]], [[securities/japan-margin-trading-and-securities-finance|margin finance]], and [[exchanges/INDEX|crypto / digital asset exchange]] research.

## Public Context

JSF Trust and Banking is small compared with full-service trust banks, but it sits in a high-leverage market-control position. When a broker, FX company, derivatives operator, crypto exchange, or security-token scheme needs legally segregated customer assets, a specialist trust bank can be part of the operating stack.

That makes the bank a peer / complement to [[trust-banks/master-trust-bank|Master Trust Bank of Japan]] and [[trust-banks/custody-bank|Custody Bank of Japan]] only at the broad "asset administration" level. Its direct peer set is narrower: trust-bank services for securities firms, margin / collateral arrangements, and regulated market operators.

## Regulatory / Research Notes

1. Identify whether the customer is a securities company, FX / derivatives operator, crypto-asset operator, crowdfunding operator, or security-token platform.
2. Separate the trust bank's trustee / administration role from investment decision-making.
3. For margin trading and securities finance, link to [[securities/japan-margin-trading-and-securities-finance|margin trading / securities finance]] and [[financial-regulators/japan-securities-finance|JSF]].
4. For security-token schemes, link to [[securities/osaka-digital-exchange|ODX]] and [[financial-licenses/securities-license-stack|securities license stack]].
5. For crypto-related trust, do not infer exchange registration; a trust-bank role is different from operating a crypto exchange.

## Caveats

- Public company history names product categories, but a specific client scheme still needs deal-level source confirmation.
- Trust structures can reduce segregation / administration risk, but they do not eliminate market, operational, or counterparty risk.
- This page is not legal, regulatory, or investment advice.
