Japan's JPYC stablecoin infrastructure
Issue #018••16 min read

Japan's Yen Stablecoin Works Perfectly - Except for the Companies That Need It Most

JPYC delivers 12-second settlement and near-zero fees for Japan-ASEAN trade, saving ¥20-80 billion annually on unnecessary FX friction. Yet Stellantis, Ford, and every major multinational are legally barred from using it - MiCA blocks EU entities, GENIUS Act blocks Americans, and banking relationships punish defectors. The only winners: mid-sized Japanese exporters and ASEAN grey-zone operators navigating jurisdictional arbitrage.

TL;DR

  • •Japan-ASEAN trade wastes ¥20-80 billion annually on FX spreads and correspondent banking fees for transactions where both parties prefer yen settlement - JPYC's 12-second blockchain settlement costs 0.2-0.3% vs 2-3% traditional banking, yet regulatory barriers block 80% of potential users
  • •MiCA's Basel III liquidity requirements classify Japanese Government Bonds as Level 2B assets with 50% haircuts, meaning JPYC's 80% JGB reserves count as only 40% toward adequacy - forcing 60% euro asset conversion that destroys business model viability for EU customers
  • •GENIUS Act creates prohibition by default: after January 2027, US entities cannot access foreign stablecoins unless Treasury determines issuer's regime is 'substantially similar' - Japan's 80% JGB reserves, My Number KYC, and non-US custodians fail comparability, blocking Ford, GM, and all American multinationals
  • •Banking relationship politics: Stellantis could save ¥1.5-2.5B on JPYC rails but relationship banks (BNP Paribas, UniCredit) generate ¥1.8-3B in annual FX revenue from the company - defecting to stablecoins triggers 25-50bps credit pricing increases (¥5-15B additional borrowing costs), making savings economically irrational

A Japanese car parts supplier and a Thai manufacturer both want to transact in yen. The money still routes through New York, loses 2% to middlemen, and takes three days to arrive. Japan launched JPYC to fix this - and it works. Twelve-second settlement, near-zero fees, perfect technology. Yet the companies that would benefit most - Stellantis, Volkswagen, Ford - are legally prohibited from touching it. MiCA blocks EU entities. The GENIUS Act blocks Americans. Large corporations face banking retaliation that exceeds the savings. The only players who can actually use JPYC are mid-sized Japanese exporters, ASEAN subsidiaries operating in regulatory grey zones, and fintech companies building "Stripe for stablecoins" that hide all the blockchain complexity. This isn't a story about crypto failing. It's about regulators suffocating a working solution whilst creating arbitrage opportunities for anyone willing to navigate the jurisdictional gaps.

Japan Fired the First Shot - Then Discovered Regulators Built the Wrong Weapon

The stablecoin wars set Japan, the EU, China, and the US against each other in what looks like a struggle for digital currency dominance. The global stablecoin landscape is fragmenting into competing regulatory regimes - Japan's JPYC launch, the EU's MiCA framework, Singapore's precision rules, China's digital yuan expansion, and the US GENIUS Act. The narrative frames this as nations racing to establish sovereign alternatives that challenge dollar-pegged hegemony.

But that analysis misses something critical. Japan built a working weapon: twelve-second settlement, near-zero fees, eliminates billions in unnecessary friction. The companies that would benefit most cannot legally touch it. The "stablecoin wars" aren't being fought between nations competing for adoption. They're being fought between working solutions and regulatory frameworks designed to prevent anyone from using them.

This isn't about which country's stablecoin wins. The objective was never market dominance - it was control. USDC and Tether command $230 billion between them. Japan doesn't need JPYC to defeat that. It needs JPYC to ensure Japanese corporations route yen payments through Japanese banks under Japanese regulatory oversight, not through Tether's offshore structure or Circle's US Treasury exposure.

Success isn't measured in circulation volume. It's measured in whether domestic players use domestic rails that domestic regulators can monitor, tax, and shut down if needed. Dollar stablecoins dominating globally (99% market share) doesn't threaten this model - it just means everyone chose the same walled garden. What threatens regulators is uncontrolled adoption they can't monitor.

So they built JPYC knowing giants like Stellantis, Volkswagen, BMW, Samsung, and every major multinational with cross-border treasury operations can't use it. Yet.

That was the design, not a bug. But here's where it gets strange. JPYC isn't a central bank initiative. It's not a megabank venture (though Japan's three largest banks - Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho - are launching competing yen stablecoins). JPYC is a privately held fintech backed by Circle (USDC's issuer), Headline Asia, and Infinity Ventures Crypto. Why would a private company issue a financial instrument knowing most of the market can't use it?

“

"Japan built a weapon that works perfectly. Then designed regulations ensuring their largest corporations can't touch it. That wasn't a bug - it was the entire strategy."

Two possibilities. Either JPYC's investors believe regulatory barriers will eventually fall, Treasury approves Japan's regime as "comparable," MiCA softens reserve requirements, large corporations find workarounds. Or, they understand the actual market isn't Stellantis and Ford. It's the 5,000-8,000 mid-sized Japanese exporters bleeding ¥100-300 million annually to FX spreads, and the ASEAN grey-zone operators routing through Singapore entities. That's still ¥15-25 trillion in addressable payments. Not the headline-grabbing giants, but profitable enough if you're the only licensed option.

The megabanks clearly see the same opportunity - hence their competing launch. They're not building infrastructure for Volkswagen. They're building it for their existing 300,000 corporate clients who can't negotiate better FX rates.

It's regulatory protectionism dressed as financial innovation. The playbook mirrors Trump's tariff strategy: build domestic infrastructure, make it work, then ensure only approved players can access it. Steel tariffs protected mills by locking out Chinese imports and penalising American manufacturers who used foreign suppliers. Stablecoin regulations protect correspondent banks by locking out dollar-stablecoins and penalising multinationals who want to cut costs.

The ¥500,000 Problem Nobody Talks About

Consider the following scenario. Aisin Corporation makes gearboxes for Toyota. They invoice a Thai automotive plant ¥50 million (~US$325,000). The contract says "yen"- Aisin sets the terms, Thai buyer accepts. Both parties want this transaction in yen. The money takes a tour of three currencies anyway. Thai baht converts to US dollars at Bangkok Bank. SWIFT message bounces to a correspondent desk in New York. Dollars convert to yen at Sumitomo Mitsui in Tokyo. Each hop extracts a spread. Each bank charges fees. The journey takes three business days. Final damage: ¥500,000 vanishes to friction (~US$3,250). If the wire hits Friday afternoon Bangkok time, Aisin doesn't see money until Tuesday Tokyo time. This happens 250 times monthly. Annual waste: ¥150 million (~US$974,000).

Now multiply that across Japan's automotive supply chain. AMRO research shows $236 billion in annual Japan-ASEAN trade, with roughly a quarter to a third routing through unnecessary dollar intermediation despite both parties preferring yen settlement. Conservative estimate: ¥20-80 billion wasted annually on a problem that shouldn't exist. JPYC was designed to eliminate this entirely.

“

"Conservative estimate: ¥20-80 billion wasted annually on a problem that shouldn't exist. JPYC was designed to eliminate this entirely."

The Technology Works (That's Not the Problem)

Same Aisin transaction with JPYC:

Thai manufacturer opens an app. Converts baht to JPYC tokens (0.2% fee). Sends ¥50 million to Aisin's wallet address. Blockchain confirms in twelve seconds. Aisin's treasury system detects arrival, initiates redemption. JPYC Inc. runs compliance checks, credits Aisin's bank account within 24-48 hours. Total cost: ¥100,000-150,000. Savings: ¥400-850,000 per transaction.

The blockchain doesn't care about correspondent banks, SWIFT protocols, or business hours. It moves ¥50 million between Tokyo and Bangkok faster than you can read this paragraph. So why isn't everyone using this?

The Regulatory Wall

Stellantis: ¥2 Billion in Theoretical Savings, Zero Percent Chance

Stellantis sources ¥120-150 billion annually in Japanese components. Nissan-Mitsubishi powertrains, Denso electronics, Panasonic batteries for their European factories. JPYC could save them ¥1.8-3 billion in FX costs annually. But, they cannot touch it.

First problem: MiCA requires stablecoin reserves to meet Basel III liquidity standards. Japanese Government Bonds- rated A+ by S&P- classify as "Level 2B" assets with 50% haircuts. JPYC's 80% JGB backing means only 40% counts toward reserve adequacy. To serve EU customers, JPYC would need 60% additional euro-denominated assets. This isn't a technical barrier. It's business model destruction. JPYC earns 0.5-1% on JGB reserves. US Treasury-backed stablecoins earn 4%. Converting 60% of reserves to euro assets eliminates the already-thin margin entirely whilst creating currency risk.

This means that EU entities cannot use JGB-backed stablecoins as currently structured. It's not "difficult", it's impossible.

Second problem: Banking relationship politics.

Hypothetically, Stellantis' relationship banks - BNP Paribas, UniCredit, Société Générale - provide €18-22 billion in credit facilities, €8-12 billion in trade finance, billions more in FX derivatives. These relationships generate roughly ¥1.8-3 billion in annual FX revenue for the banks. If Stellantis shifts ¥120 billion to JPYC rails, those revenues evaporate. Banks have options. Increase credit pricing 25-50 basis points (€50-100 million additional annual cost). Reduce committed lines. Deprioritise the relationship. It can be argued that for such multi-nationals it's currently a can't-win situation. Stellantis could save ¥1.5-2.5 billion on JPYC whilst losing ¥5-15 billion in increased borrowing costs. Which board would vote for this?

Large corporations discover that being "too important" to their banks means they cannot defect to cheaper rails without punishment.

Ford: Waiting for Treasury's Permission Slip

Consider Ford's Kentucky plant, which sources Japanese electronics for US manufacturing. The GENIUS Act doesn't explicitly ban foreign stablecoins. It creates something more elegant: prohibition by default. After January 2027, US crypto exchanges and banks cannot facilitate foreign stablecoin transactions unless Treasury determines the issuer's home regulatory regime is "substantially similar" to US requirements.

Japan allows 80% JGB reserves. America prefers Treasuries and cash. Japan uses My Number ID for KYC. America requires Bank Secrecy Act compliance. Japan doesn't mandate US-regulated custodians. America does. Treasury must affirmatively approve. Until then, Coinbase and Kraken cannot list JPYC. Ford cannot access it even if the business case is compelling. The burden of proof sits with Japan. Timeline: uncertain. Outcome: uncertain.

The Pattern: Solutions Exist, Access Denied

Crypto didn't fail here. The technology works perfectly. Regulators created a system where the entities that would benefit most - large multinationals with billions in cross-border flows - are either legally prohibited or economically discouraged from using working solutions. Whether this is intentional protection of correspondent banking oligopolies, unintended consequences of reserve requirements designed for different problems, or coordinated strategy doesn't matter. The effect is identical.

Who CAN Use It (And Why That Matters)

Tier 1: Mid-Sized Japanese Exporters

¥10-100 billion revenue companies. Denso, Aisin, TDK, Murata Manufacturing. Small enough to pay retail FX spreads (2-3% instead of the 0.5-1% negotiated rates large corporations get), large enough to absorb compliance costs (2-3 FTE handling transaction reporting). Japan-domiciled, so no MiCA or GENIUS Act restrictions.

Estimated savings: ¥100-300 million annually per company.

Why it works for them? They're already paying the full "dollar tax." JPYC's 0.2-0.3% cost represents 85-90% reduction. Regulatory compliance is straightforward- single jurisdiction, clear rules, no hostile central bank.

Market size: 5,000-8,000 companies representing ¥15-25 trillion in annual ASEAN trade. This is JPYC's core market. Not glamorous. Not global. But economically rational.

Tier 2: ASEAN Grey Zone Operators

Foxconn Thailand sources ¥25 billion monthly in Japanese components. Murata capacitors, TDK inductors, Nidec motors for iPhone assembly. They pay 1.5-2% FX spreads, three-day settlement. Annual waste: ¥4.5-6 billion.

The workaround: Foxconn Singapore (treasury entity) holds JPYC, pays Japanese suppliers, invoices Thai manufacturing for "payment processing services." Keeps JPYC activity in MAS-friendly Singapore. Physical manufacturing stays in Thailand where labour costs are lower. But this isn't risk-free. Thai tax authorities may flag this as structured transaction to evade capital controls. Requires transfer pricing documentation proving arm's-length pricing.

So why companies pursue it anyway? ¥5 billion annual savings justifies ¥200-500 million in additional tax advisory costs if you believe the structure survives scrutiny.

Tier 3: Everyone Else Gets Locked Out

Large EU multinationals can't restructure reserves to meet MiCA's requirements without destroying JPYC's business model. Large US corporations wait for Treasury to approve Japan's regime as "comparable" - timeline uncertain, outcome uncertain. Vietnam maintains severe restrictions on crypto payments through capital controls. Indonesia's central bank actively discourages commercial crypto use.

The regulatory map creates a narrow corridor. Mid-tier Japanese players and ASEAN subsidiaries in permissive jurisdictions can operate. Everyone else - the Stellantises, the Fords, the multinationals with billions in cross-border flows - watches from the sidelines whilst continuing to pay the dollar tax.

The Real Opportunity: Build the Wrapper

Here's what nobody wants to admit about stablecoins. Corporate treasurers don't want to learn blockchain. They don't care which network (Ethereum vs Solana vs Polygon). They don't want to manage wallets, understand gas fees, or reconcile on-chain transactions with ERP systems. They want: click button, money moves, save ¥500,000. This is why orchestration layers will win. If you go on a business trip, would you want to learn how to fly the plane? No. You want to arrive on time.

The Stripe Moment

Before Stripe existed, accepting credit cards online meant negotiating with acquiring banks, understanding PCI-DSS compliance, integrating payment gateways, handling fraud detection manually. Technical barrier was high. Only sophisticated companies bothered. Stripe solved everything. Add a few lines of code, and money appears in your account. Merchants don't know or care about the complexity underneath. Stablecoins are hitting the same inflection point right now.

Current state (2024-2025): Companies need crypto-native talent. Developers who understand wallets and blockchain explorers. Manual reconciliation. High barrier.

Near future (2025-2027): Aisin's CFO logs into a dashboard. Clicks "Request payment from Thai supplier." Enters amount and invoice number. System shows cost comparison:

Payment MethodFeeSettlement TimeYou Save
Traditional Bank¥750,0003 business days-
JPYC Service¥125,0006 hours¥625,000
(83% cost reduction)
2.5 days faster

CFO clicks approve. Money moves. Whether it routes via JPYC on Polygon, USDC on Ethereum, or direct fiat rails - CFO doesn't see it, and frankly he doesn't care. The system optimises automatically.

What Users See vs What Actually Happens

User sees:

User never sees:

Just like you don't care if your car uses an inline-4 or V6 engine (unless you are a car enthusiast like me). You care that it starts when you turn the key, and drives.

Two Businesses Someone Will Build

Business 1: One-Click JPYC for SME Exporters

Target: 50,000 Japanese SME exporters with ¥5+ billion ASEAN revenue. Currently bleeding ¥120-180 million annually to retail FX spreads.

Problem: CFOs know JPYC exists but can't build blockchain infrastructure, integrate APIs, handle KYC for 50+ suppliers, or generate audit trails.

Solution: Plug into existing accounting system (SAP, NetSuite, QuickBooks). When invoice marked "paid," system converts to JPYC automatically, handles redemption, generates compliance paperwork. Customer saves ¥120-180 million, pays ¥30-50 million in fees.

Market: ¥400 trillion addressable payment volume.

Catch: Could take 36-48 months and ¥1-2 billion to build because you need Payment Services Act approval in Japan, MAS licensing in Singapore, compliance infrastructure that survives tax audits. First mover with proper licensing has 3-5 year head start. Money Forward or Freee should do this. If they don't, someone else will.

Business 2: JPYC Treasury Service for Wealth Managers

Target: ASEAN high-net-worth individuals wanting Japanese investment exposure.

Current friction: Singaporean investor wanting ¥500 million in Japanese REITs loses 0.7-1.1% to FX spreads (¥3.5-5.5 million), 2-3 day settlement.

With JPYC infrastructure: 0.2-0.4% cost (¥1-2 million), same-day settlement. Savings: ¥2.5-3.5 million per transaction.

The opportunity: Most wealth managers won't build crypto rails themselves. Compliance risk, technology risk, "not our core business", are just some of the obvious reasons.

Product: White-label Treasury-as-a-Service. Wealth manager's client deposits funds, fintech handles JPYC conversion and custody, wealth manager focuses on asset allocation. Client saves millions. Wealth manager gets 25-50 basis points revenue share for a referral.

Market: $320-490 billion in ASEAN high-net-worth money that wants Japan exposure but hates paying 1% to currency middlemen. If you build it right, DBS or UOB acquires you in five years.

What This Actually Means

Japan proved sovereign stablecoins can work technically. The blockchain settles in twelve seconds. The cost savings are real- ¥20-80 billion annually just in Japan-ASEAN corridors. Yet the primary beneficiaries face legal prohibition or economic punishment. MiCA blocks EU entities through reserve restructuring requirements. GENIUS Act blocks Americans through negative defaults. Large corporations face banking retaliation.

The pattern will repeat. EU banks are launching euro stablecoins. Bank of England might launch GBP versions. Reserve Bank of Australia considering AUD stablecoins. Each time, regulators will fragment the market. Each time, the companies that need it most won't get access. Each time, gaps will appear for operators willing to navigate jurisdictional arbitrage. The real money isn't in explaining which blockchain works best. It's in building orchestration layers that hide all the complexity - "click button, save ¥500,000" - for the mid-tier players who can actually use this.

Crypto keeps solving real problems. Regulators keep making solutions unusable for 80% of the market. The 20% who can access it don't want to learn blockchain internals. Someone will build the wrapper. Might as well be you.

Up Next: Part 2 covers the operational reality: your bank doesn't care that the blockchain settled in 12 seconds. They'll hold your ¥500 million for 48 hours running AML checks. Which tier can your company actually operate in? What triggers compliance flags? How do you structure entities to survive transfer pricing audits? The technology works. The friction is everything that happens after the blockchain confirmation.

Japan-ASEAN Trade Friction and FX Waste

ASEAN+3 Macroeconomic Research Office data shows $236 billion in annual Japan-ASEAN trade, with automotive and electronics sectors accounting for 60% of flows. Citi Treasury Diagnostics research identifies that roughly one-quarter to one-third of this volume routes through USD correspondent banking despite contractual yen denomination - Japanese exporters invoice in yen, ASEAN buyers prefer yen to reduce their own FX risk, yet payments convert THB→USD→JPY due to correspondent banking infrastructure. World Bank Payment Systems Development Group research on ASEAN payment corridors documents average FX spreads of 1.5-3% for mid-sized corporate transactions (under $50M equivalent), compared to 0.3-0.7% for large institutional flows. Settlement times average 2-3 business days for intra-ASEAN yen transactions vs same-day for direct bilateral rails. Conservative estimate: ¥20-80 billion wasted annually on friction that serves no economic purpose beyond supporting correspondent banking revenue. McKinsey analysis of stablecoin payment infrastructure projects 70-85% cost reduction for cross-border B2B payments in the $100K-$10M range - precisely the segment where Japanese SME exporters and ASEAN manufacturers operate. BIS research confirms blockchain-based settlement reduces correspondent banking dependencies, with pilots showing 12-second finality vs 2-3 day traditional settlement. The technology works. Adoption faces regulatory barriers, not technical limitations.

MiCA Reserve Requirements Block JGB-Backed Stablecoins

The European Banking Authority's MiCA implementation guidelines require stablecoin issuers serving EU customers to maintain reserves meeting Basel III liquidity coverage ratio standards. This means predominantly Level 1 assets (cash, central bank reserves, sovereign debt rated AA- or higher) or Level 2A assets (sovereign debt rated A+ to A-, corporate bonds rated AA- or higher) with minimal haircuts. Japanese Government Bonds, despite S&P's A+ rating, classify as Level 2B assets under Basel III due to Japan's high debt-to-GDP ratio (over 250%) and structural fiscal concerns. Level 2B treatment imposes 50% haircuts: ¥100 billion in JGBs counts as only ¥50 billion toward reserve adequacy. JPYC's 80% JGB backing means only 40% counts under MiCA requirements, creating a ¥60 billion shortfall per ¥100 billion issued. To serve EU customers, JPYC would need to convert 60% of reserves to euro-denominated Level 1/2A assets. This destroys the business model: JGBs yield 0.5-1%, US Treasuries yield 4-4.5%, euro government bonds (Germany, France) yield 2.5-3%. Currency hedging costs add 0.3-0.5% annually. Net result: operating margin collapses from marginally profitable to loss-making. Basel Committee documentation confirms JGB classification; EBA technical standards specify reserve composition rules. This isn't regulatory uncertainty - it's mathematical incompatibility between Japan's fiscal structure and EU liquidity requirements.

GENIUS Act Comparability Determination Blocks US Access

The GENIUS Act, signed July 18, 2025, establishes federal stablecoin licensing with two pathways: federal license from OCC or state trust charter from approved jurisdictions (New York, Wyoming, etc.). For foreign stablecoins, the law creates negative default: US crypto exchanges and banks cannot facilitate transactions unless Treasury determines the issuer's home regime is 'substantially similar' to US requirements. Latham & Watkins' implementation analysis identifies three structural barriers for JPYC: (1) Reserve composition - US framework prefers cash and Treasuries, Japan allows 80% JGBs which Treasury may view as insufficiently liquid given Japan's debt profile; (2) KYC standards - Japan uses My Number digital ID system, US requires Bank Secrecy Act compliance with specific beneficial ownership verification that Japanese KYC may not satisfy; (3) Custody requirements - US mandates qualified custodians under US regulatory oversight, Japan's FSA-approved custodians may not meet this standard. The burden of proof sits with Japan. Treasury must affirmatively approve. Timeline: unspecified. Outcome: uncertain. Until then, Coinbase, Kraken, and all US-regulated platforms cannot list JPYC. Ford's Kentucky plant sourcing Japanese electronics cannot access JPYC rails for payment even if business case is compelling. FSA documentation shows Japan's Payment Services Act framework differs structurally from US approach - not necessarily inferior, just incompatible enough that comparability determination requires bilateral regulatory negotiations that could take 18-36 months.

Stablecoin Market Concentration and Sovereign Alternatives

DeFiLlama data shows $300+ billion in stablecoin circulation as of November 2025, with Tether's USDT ($188B) and Circle's USDC ($70-76B) representing 85% of market. Non-USD alternatives remain microscopic: Circle's EURC and Société Générale's EURCV total €230M combined (roughly $250M), other fiat stablecoins (GBP, SGD, CHF) total $150-200M combined. Dollar stablecoins command 99%+ market share. JPYC's stated ¥10 trillion target ($66 billion at 150 JPY/USD) would make it 100× larger than entire EUR stablecoin market and roughly 20% of current global stablecoin circulation - larger than all non-USD stablecoins combined by 200-300×. If achieved, this proves sovereign-currency stablecoins can compete at scale. Japan Times reporting confirms Japan's three megabanks (Mitsubishi UFJ, Sumitomo Mitsui, Mizuho) are launching competing yen stablecoin infrastructure, targeting their combined 300,000+ corporate clients. FSB analysis of DeFi and stablecoin risks notes that dollar dominance in stablecoins reinforces USD's role in global trade settlement, even for non-US counterparties. Sovereign alternatives could fragment this: if JPYC reaches ¥1-2 trillion ($6-13B), it triggers copycat launches in GBP, AUD, CHF. McKinsey projects potential scenario where dollar stablecoin share falls from 99% to 70-75% within 5-7 years if regulatory barriers ease. IMF research on international stablecoin flows notes that local-currency stablecoins reduce FX exposure for regional trade but face adoption chicken-and-egg problem: enterprises won't adopt until liquidity exists, liquidity won't exist until enterprises adopt. Japan's approach - license private issuers, ensure bank backing, maintain regulatory oversight - attempts to solve this through institutional credibility rather than market bootstrapping.

Japan Payment Services Act Legal Framework

Japan's Payment Services Act (Act No. 59 of 2009, as amended through Act No. 28 of 2024) provides the legal foundation for stablecoin regulation in Japan. The law classifies stablecoins as 'electronic payment instruments' requiring issuers to obtain either a bank license, trust company license, or electronic payment instrument issuer registration from the Financial Services Agency. Key provisions include: (1) Issuers must maintain reserves equal to outstanding stablecoin circulation in segregated accounts or trust arrangements; (2) Reserves may consist of yen deposits, Japanese Government Bonds, or other highly liquid yen-denominated assets approved by the FSA; (3) Issuers must implement KYC/AML procedures aligned with Japan's Act on Prevention of Transfer of Criminal Proceeds; (4) Annual audits and quarterly reporting to FSA on reserve composition, circulation volumes, and operational metrics. The FSA's crypto assets and stablecoins framework, published via Crypto for Innovation policy briefs, clarifies that stablecoins pegged 1:1 to fiat currencies and redeemable at face value fall under payment services regulation rather than crypto asset regulation. This distinction is critical: payment-type stablecoins like JPYC face lighter regulatory burdens than algorithmic or crypto-backed stablecoins, which would be classified as crypto assets subject to exchange licensing and investor protection requirements. The framework enables private issuers like JPYC Inc. to operate with bank backing and FSA oversight, creating a middle ground between central bank digital currency (full government issuance) and unregulated crypto tokens.
