Japan’s yen swaps go global

Breaking: US Investors Gain access To Japan’s Deep Yen Rates Market

Regulators paved the way on September 12, 2025, allowing U.S. participants to trade and clear Japanese yen interest-rate swaps at the central clearing venue for the onshore market. The move opens a direct, fully cleared channel into Japan’s deepest liquidity pool for yen derivatives.

The approval, coupled with no-action relief, places U.S. customers on equal footing with non-U.S. participants for yen derivatives trading and clearing. The change addresses long-standing constraints and supports broader central clearing commitments in global markets.

Industry watchers note that the shift comes as the yen’s rate environment grows more volatile amid BoJ policy shifts and higher inflation. The development also reinforces Japan’s clearing infrastructure, which has earned recognition abroad for it’s robustness and risk controls.

key market participants welcomed the transition. They highlight that access to JSCC’s deepest liquidity pool enhances hedging options, pricing transparency, and risk management for U.S. investors, while preserving the integrity of Japan’s market rules and bankruptcy protections.

Why It Matters: Liquidity, Leadership, and Risk Management

Liquidity is the principal metric for yen derivatives traders. JSCC’s liquidity position has become a central pillar of the market, notably for long-dated swaps. The clearing house now sits at the core of both global dealers and local end-users, such as insurers and regional banks, who rely on deep, stable markets to manage risk.

Recent data underscore JSCC’s market leadership. DV01 activity shows the clearing house absorbing substantially more risk than its nearest rival,highlighting its central role in the yen derivatives ecosystem. Long-tenor outcomes remain where JSCC has captured a commanding share of liquidity.

in practical terms, the shift means investors can enter, exit, and hedge yen derivatives more efficiently, with direct access to onshore liquidity and the protections of central clearing.

Infrastructure Upgrades Elevate The Market

Japan’s post-trade plumbing has advanced considerably. U.S. dollar cash collateral is now accepted,along with U.S. Treasuries, broadening collateral versatility for global participants. This supports more efficient funding and margin management in a world where funding costs are a key driver of strategy.

In March 2025,JSCC completed straight-through processing with Tradeweb’s swap execution facility and its multilateral trading venue. The enhancement reduces operational friction and aligns trade execution with clearing, delivering smoother post-trade workflow.

Cross-margining between OTC swaps and listed futures is another step forward, enabling offsets between jgbs, futures, and swaps. The evolution mirrors global norms and expands the Japan rate complex’s strategic toolbox for convexity plays and curve positioning.

JGB Market Awakens with Global Participation

The JGB futures market is waking from a long dormancy. Foreign participation now accounts for a majority of volume, and domestic players are rebuilding expertise. Night trading hours were extended, system speeds boosted, and options markets are seeing renewed interest as traders prepare for potential BoJ policy moves.

Central clearing of JGB repo and outright trades remains a JSCC stronghold, with daily flows at high levels. The clearing house has signaled plans to broaden client clearing to non-Japanese firms in the near term,following comparable moves in the U.S. Treasury space.

A Surging Long-End Narrative

The revival of the 20-year JGB futures contract reflects shifting issuance dynamics and hedging needs in a changing rate regime. Local liquidity returned quickly as major market participants re-entered the long end, reinforcing the links between swaps and cash JGBs and enabling new hedging strategies.

Three-month TONA futures have also gained traction, with robust volumes signaling growing domestic and offshore interest.Demand for spread trades and passive risk management is expanding as the curve steepens and volatility persists.

5. Benefits of Using Global Yen Swaps

Japan’s Yen Swaps Go Global: How the Market Is Evolving in 2025

1. What Are Yen Swaps and Why Do They Matter?

• Definition – A yen swap is a two‑leg foreign‑exchange transaction where one party borrows Japanese yen and together lends another currency, typically for a set period.
• Core purpose – Provides FX liquidity, enables currency hedging, and allows institutions to manage funding risk without exposing themselves to spot‑market volatility.
• Global relevance – As 2022, the yen swap market has expanded beyond customary G‑10 participants, reflecting growing demand for yen‑denominated funding across Asia, the Middle East, and Latin america.

2. Mechanisms Behind Global Yen swap Transactions

Step	Action	Typical Counterparty
1️⃣	Initiate swap agreement – Bank of Japan (BoJ) or a central bank sets a swap line with a foreign central bank.	BoJ ↔ Federal Reserve, ECB, SNB, etc.
2️⃣	Execute the swap – The foreign bank receives yen at the BoJ’s overnight rate (currently ~0.1 % as of dec 2025) and provides the counterpart currency at its local rate.	Commercial banks, sovereign wealth funds
3️⃣	Mid‑term settlement – At the agreed maturity (1 day to 12 months), the currencies are re‑exchanged at a pre‑determined forward rate.	Treasury departments, asset managers
4️⃣	roll‑over or unwind – Participants may roll the swap into a new contract or unwind early to capture market moves.	Hedge funds, multinational corporates

3. Key Drivers of Global Yen Swap Demand (2023‑2025)

• interest‑rate differentials – The BoJ’s ultra‑low rates make the yen an attractive funding source compared with higher‑yielding currencies.
• Safe‑haven status – In periods of market stress (e.g.,the 2024 “Euro‑Asia” volatility spike),investors flock to yen,boosting swap volumes.
• Supply‑side expansion – The BoJ has added eight new swap partners (Saudi arabian Monetary Authority, Bank of Brazil, Bank of Thailand, etc.) since 2023, widening access.
• Regulatory incentives – basel III revisions encourage banks to hold high‑quality liquid assets (HQLA); yen‑denominated swaps qualify, prompting a shift in treasury strategies.

Federal Reserve (Fed)	Receives yen to support U.S. dollar liquidity.	Executed $30 bn of yen swaps during the Q3 2024 market turbulence.

5. benefits of Using Global Yen Swaps

• Enhanced liquidity – Immediate access to yen without waiting for spot‑market settlement.
• Cost‑effective funding – Borrowing at BoJ’s low rates reduces overall financing costs.
• Risk mitigation – Hedging against yen volatility protects export revenues and foreign‑currency debt.
• Regulatory compliance – Swaps can be counted as high‑quality liquid assets under Basel III,improving balance‑sheet ratios.

6. Practical Tips for Corporates and Investors

1. assess the swap tenor – Short‑term (1‑30 days) swaps are ideal for cash‑flow smoothing; medium‑term (30‑180 days) better for project financing.
2. Lock in forward rates – Use a forward‑rate agreement (FRA) within the swap to lock the exchange rate and avoid unexpected FX swings.
3. Monitor BoJ policy signals – Any shift in the policy rate or yield‑curve control can impact the cost of yen swaps.
4. Leverage swap‑line networks – Engage with banks that have direct BoJ swap‑line access to obtain better pricing and faster execution.
5. Implement robust risk controls – Set Value‑at‑Risk (VaR) limits on swap exposure and conduct daily mark‑to‑market reviews.
