Japan rates derivative product matrix

TL;DR

Japan’s yen-rates complex spans IRS, TONA OIS, JGB futures, swaptions, CMS, inflation swaps, and yen cross-currency swaps, with JGB inflation-linked bonds included as a cash-market comparison. The current JPX physically delivered JGB-futures lineup is 5-year, 10-year, and mini 20-year; mini 10-year JGB futures are a separate cash-settled product. This matrix confines comparisons to contract form, reference, and official verification surface. Aggregate statistics do not establish current dealer rankings, product-level end-user intensity, or dealer revenue.

Wiki route

This entry sits under derivatives index. It pairs with Japan yen IRS market for the headline OTC swap lane, OIS / TONA curve for the discount-curve and RFR lane, JGB futures curve for the exchange-listed hedge lane, yen-USD CCBS for the cross-currency intersection, Japan swaption market for the option-on-IRS lane, Japan CMS for the slope-curve product, Japan inflation swap for the CPI-linked hedge lane, and JGBi for the cash-side inflation-linked underlying. The cash market is money-market index and the corporate end-user side is corporate FX and rate hedge policy.

Why a rates-derivative product matrix matters

A single phrase like “Japan rates derivative” hides the fact that the clearing venue, notional scale, participant mix, and end-user use case differ across products. Without classification:

• a yen IRS looks like a yen OIS even though the floating reference (TIBOR vs TONA) and discount-curve role differ;
• a JGB future looks like a swap even though one is exchange-listed and physically delivered, the other is OTC and net-settled;
• a swaption looks like a vanilla option even though it is the optionality layer on the underlying IRS curve, with distinctive life-insurer demand;
• a CCBS looks like an FX swap even though it is the funding-arbitrage instrument that links yen and USD term funding;
• an inflation swap and a JGBi look interchangeable even though one is OTC derivative and the other is cash-bond market.

The matrix puts each product in its place so that any single derivative page can be read against its alternative hedge route or its cash-market underlying.

Product 1 — Yen IRS (TIBOR-floating)

• Instrument type. OTC fixed-for-floating swap referencing a defined Japanese Yen TIBOR tenor. See Japan yen IRS market.
• Verification surface. JBATA for benchmark status; JSCC for products eligible for its IRS clearing service; BIS and BOJ for aggregates.
• Boundary. Product eligibility, a legal clearing mandate, liquidity by tenor, and a named institution’s position are separate questions.

Product 2 — Yen OIS (TONA)

• Instrument type. OTC fixed-for-floating swap referencing compounded TONA. See OIS / TONA curve.
• Verification surface. BOJ for TONA publication; JSCC for eligible OIS products and criteria.
• Boundary. Discounting, collateral, compounding, and tenor conventions are contract-specific.

Product 3 — JGB futures (10Y standard)

• Instrument type. Osaka Exchange physically delivered futures on a 10-year notional JGB, with a JPY100 million trading unit. See JGB futures curve.
• Verification surface. JPX contract specifications, delivery rules, and derivatives statistics.
• Boundary. Open interest and volume vary by dated contract and should not be replaced with an undated magnitude.

Product 4 — Other current JGB futures

• Physically delivered. 5-year JGB futures use a JPY100 million trading unit; mini 20-year JGB futures use JPY10 million.
• Cash settled. Mini 10-year JGB futures are cash settled and use a JPY10 million trading unit.
• Boundary. JPX’s current specification does not list a standard JPY100 million 20-year JGB futures contract; do not conflate mini 20-year with mini 10-year.

Product 5 — JGB inflation-linked bond (JGBi)

• Instrument type. MOF-issued cash bond, not a derivative, whose principal is indexed to CPI excluding fresh food. See JGBi.
• Verification surface. MOF product, auction, and indexation-coefficient pages.
• Boundary. The bond can inform a cash-market breakeven comparison, but its yield is not interchangeable with an inflation-swap quote.

Product 6 — Swaption (option on yen IRS)

• Instrument type. OTC option on a defined underlying yen IRS, with exercise and settlement terms in the confirmation. See Japan swaption market.
• Verification surface. ISDA product documentation and the specific confirmation.
• Boundary. Aggregate interest-rate-option data does not establish a Japan dealer ranking, a “most liquid” grid point, or a named investor’s direction.

Product 7 — CMS (constant-maturity swap)

• Instrument type. OTC swap whose CMS leg references a defined constant-maturity swap rate. See Japan CMS.
• Verification surface. ISDA product documentation and the trade confirmation.
• Boundary. The current JSCC eligible-product page does not establish broad CMS clearing, liquidity, or participant intensity.

Product 8 — Inflation swap (CPI-linked)

• Instrument type. OTC swap exchanging fixed and defined CPI-linked cash flows. See Japan inflation swap.
• Verification surface. Statistics Bureau for the named CPI series; ISDA definitions and the confirmation for payoff mechanics.
• Boundary. Reference index, lag, interpolation, clearing status, tenor, and investor use are contract-specific.

Product 9 — Yen-USD cross-currency basis swap (CCBS)

• Instrument type. OTC swap exchanging defined cash flows in two currencies, potentially including initial and final principal exchanges and a basis spread. See yen-USD CCBS and yen basis swap market.
• Verification surface. ISDA mechanics, BIS aggregate analysis, and the trade confirmation.
• Boundary. Sign convention, spread leg, tenor, collateral, clearing, and end-user purpose cannot be inferred from the product name alone.

How to read this matrix

The rates-derivative product matrix is a public-surface tool. When reading any single product page:

1. Start with legal form. Distinguish listed futures, OTC derivatives, and the JGBi cash bond.
2. Name the exact reference. TIBOR, TONA, CPI, a futures price, and a CMS rate are not interchangeable.
3. Separate eligibility from obligation. A CCP eligible-product list does not by itself establish that a trade must clear.
4. Align datasets. BIS/BOJ notional, JPX contract volume, and MOF bond amounts have different units and populations.
5. Demand dated evidence for behavior claims. Participant direction, liquidity, dealer share, and revenue require a specific disclosure or dataset.

Boundary cases and caveats

• IRS vs OIS. Both can be fixed-for-floating swaps, but the named benchmark and calculation method differ; Japanese Yen TIBOR remains active.
• Listed futures vs OTC swap. A 10Y JGB future hedges duration but is anchored to the 10Y CTD; an OTC 10Y IRS hedges the exact 10Y swap rate at the trade tenor. Insurer ALM uses both, with different basis behavior.
• JGBi vs inflation swap. JGBi is a cash MOF-issued bond delivering inflation-indexed cash flows; an inflation swap is an OTC derivative without principal exchange. Both reference all-Japan CPI ex-fresh-food. Hedge-fund inflation-breakeven trades typically combine JGBi and OIS or use inflation swap directly.
• Swaption vs option on JGB future. A swaption references a defined swap, while an exchange-listed option on JGB futures references the futures contract; activity comparisons require a dated, like-for-like dataset.
• CMS vs vanilla swap. A CMS swap pays a periodically reset CMS rate (a swap rate of constant maturity) rather than a periodically reset short-tenor floating rate. The “constant maturity” feature changes the convexity and vol-surface dependence.
• Cross-currency swap vs FX swap. Contract structures and cash-flow schedules differ; the exact principal exchanges, rate legs, spread convention, and maturity must be stated before comparing them.
• BIS notional vs gross market value. BIS publishes both gross notional outstanding and gross market value semi-annually. Gross notional is the headline number for size comparison; gross market value (much smaller) is the closer-to-real-exposure number. Always cite the survey vintage.
