Read it with [[financial-licenses/INDEX|JapanFG legal / financial licenses]], [[securities/financial-instruments-business-operators-japan-index|FIEA operator registry]], [[banking/INDEX|banking domain]], and [[money-market/INDEX|money-market domain]] when prime brokerage becomes a license, custody, collateral, or funding question. ## Overview Prime brokerage in Japan is not a single license label. It is a wholesale service stack built from Type I financial instruments business, broker-dealer execution, margin finance, securities lending, stock-borrow, derivatives, repo / collateral operations, custody, clearing, and settlement.

It restates licence / structure / product boundaries from those materials and does not invent market share, ranking, or unstated numerical claims. ^[source:fsa.go.jp; jsda.or.jp; jpx.co.jp] | Function | Legal / regulatory anchor | Infrastructure rail | Main risk | |---|---|---|---| | Execution | Type I FIBO / broker-dealer route. | Exchange, PTS, broker routing, SOR. | Best execution, order marking, market abuse. | | Cash financing | Margin / loan trading and bilateral credit arrangements. | Broker balance sheet, JSF, collateral account. | Leverage, margin calls, liquidation. | | Securities borrow | Stock lending / borrowing and locate / cover arrangements. | Custodian, lender, borrower, JSF, JASDEC. | Fail, recall, scarcity, short-sale compliance. | | Synthetic exposure | Derivatives / swaps / CFD-like exposure where licensed. | Dealer risk book, margin, collateral, documentation. | Counterparty, valuation, close-out, suitability. | | Custody / settlement | Client asset segregation, DVP, JASDEC / JSCC routes. | Custodian, broker, CCP, CSD. | Asset segregation, settlement fail, operational risk. | | Collateral operations | Cash / securities collateral and margining. | Custodian, broker, CCP, treasury. | Reuse / rehypothecation-like exposure, concentration, liquidity. | ## Actor Map | Actor | Role | |---|---| | Prime broker | Provides financing, stock borrow, execution access, reporting, and collateral operations to institutional clients. | | Executing broker | Routes and executes orders; may or may not be the financing broker. | | Custodian | Holds assets, handles corporate actions, and supports asset segregation / lending programs. | | Securities finance company | [[financial-regulators/japan-securities-finance|Japan Securities Finance]] supports standardized margin and securities-finance routes. | | CCP / CSD | [[securities/japan-securities-clearing-corp|JSCC]] clears; [[securities/japan-securities-depository-center|JASDEC]] supports depository / settlement routes. | | Client | Hedge fund, asset manager, proprietary account, market maker, or other institutional investor. | ## Retail Margin Is Not Prime Brokerage [[securities/japan-margin-trading-and-securities-finance|Retail margin trading]] is important plumbing, but it is not the same as institutional prime brokerage. Retail margin explains standardized / negotiable margin, broker credit, JSF, and stock-loan controls. Prime brokerage adds broader institutional financing, portfolio-level collateral, short access, synthetic exposure, custody / reporting, and multi-market execution. ## Financing Route Map | Route | How to read it | Pages to open | |---|---|---| | Cash margin | Client borrows money or securities against collateral. | [[securities/japan-margin-trading-and-securities-finance|margin trading route]] | | Stock borrow | Securities borrowed for short sale, hedge, market-making, or settlement coverage. | [[securities/japan-stock-lending-market-route|stock lending route]] | | Short-sale control | Order marking, price restrictions, position disclosure, and issue-level measures. | [[securities/japan-short-selling-and-stock-loan-controls|short-selling controls]] | | Repo / collateral | JGB or securities collateral supports financing and liquidity. | [[money-market/jgb-repo-market-japan|JGB repo market]] | | DVP / settlement | Cash and securities move through CCP / CSD settlement rails. | [[securities/japan-market-infrastructure-map|market infrastructure map]] | ## JapanFG Company Routing | Company page | Likely wiki role | |---|---| | [[securities-firms/nomura-hd|Nomura]], [[securities-firms/daiwa-sg|Daiwa Securities Group]] | Domestic wholesale securities / prime finance / institutional brokerage anchors. | | [[securities-firms/smbc-nikko|SMBC Nikko]], [[securities-firms/mizuho-securities|Mizuho Securities]], [[securities-firms/mufg-mums|MUMSS]] | Megabank securities arms with institutional financing / brokerage context. | | [[securities-firms/goldman-sachs-japan|Goldman Sachs Japan]], [[foreign-financial-institutions/jpmorgan-japan|J.P.

Identify activity first: execution, margin, stock borrow, derivative, custody, collateral, or reporting. 2. Verify legal status against FSA FIBO list and JSDA membership where applicable. 3. Separate client-facing product pages from actual Japan legal entity / registration. 4. Check short-selling, stock-loan, and issue-level restriction pages before interpreting a borrow as available. 5. For global banks, route entity questions through [[financial-licenses/foreign-financial-group-adjacent-licenses|foreign financial group adjacent licenses]]. ## Caveats - Prime brokerage terms are often contractual and client-specific; public pages usually describe capabilities, not individual client terms. - This page records no suitability, leverage, or investment endorsement. - Current license status be refreshed from FSA / JSDA sources for live use. ## Related - [[securities/INDEX]] - [[securities/japan-margin-trading-and-securities-finance]] - [[securities/japan-stock-lending-market-route]] - [[securities/japan-short-selling-and-stock-loan-controls]] - [[securities/japan-market-infrastructure-map]] - [[securities/japan-securities-clearing-corp]] - [[securities/japan-securities-depository-center]] - [[financial-licenses/securities-license-stack]] - [[financial-regulators/japan-securities-finance]] - [[INDEX|FinWiki index]] ## Sources - FSA: FIBO list, FIEA FAQ, and supervisory guidelines for financial instruments business operators. - JSDA: member list and borrowing / lending transaction guidelines for share certificates. - JPX / JSCC / JASDEC: margin trading, DVP settlement, and institutional settlement public pages. - JSF: public restriction / loan information for margin transactions. - Nomura and J.P.
