Özet

The Bank for International Settlements (BIS) Working Paper No. 170 analyzes the rise of stablecoins and their impact on the global monetary system. Stablecoins, privately issued digital tokens pegged to fiat currencies, have grown exponentially since 2014, with a market dominated by USD-pegged variants like USDT and USDC. Their core function remains within the crypto ecosystem, though use in cross-border payments and as a store of value in high-inflation emerging markets is increasing. The report identifies stablecoins as a new form of offshore dollar claims, extending dollar liquidity via blockchain. Their stability depends entirely on reserve quality and market arbitrage, lacking traditional banking safeguards. In the short term, stablecoins reinforce the US dollar's dominance, posing risks to monetary sovereignty in emerging market and developing economies (EMDEs) by facilitating "digital dollarization," which can undermine local currency deposits, capital controls, and monetary policy effectiveness. The BIS outlines three potential future scenarios: 1) Niche adoption within crypto (baseline), 2) Widespread "digital dollarization" in EMDEs (high-risk), and 3) Integration of domestic currency stablecoins (ideal but challenging). Effective global regulatory coordination is crucial to manage risks like reserve transparency, cross-border spillovers, and illicit activities. The report concludes that stablecoins represent a structural force reshaping international monetary hie...

With the rapid development of global digital finance, stablecoins have evolved from niche tools within the crypto sector to become new types of digital assets with cross-border payment and value storage functions, profoundly impacting the international monetary landscape. In May 2026, the Bank for International Settlements (BIS) released Working Paper No. 170, systematically analyzing the development characteristics, operational mechanisms, and impact of stablecoins on the international monetary system, while proposing three future scenarios and regulatory approaches. The report concludes that stablecoins will reinforce the dominance of the US dollar in the short term, posing risks to the monetary sovereignty of emerging markets and developing economies (EMDEs). Their long-term trajectory will depend on their adoption models, regulatory responses, and synergy with the digital finance ecosystem.

Stablecoin Market: Soaring Scale, Dollar Dominance

Stablecoins are privately issued blockchain tokens pegged to fiat currencies or assets to maintain stable value, combining payment and storage functions. Since the first stablecoin emerged in 2014, the industry has grown exponentially; by 2026, there were over 300 active stablecoins globally, with a total market capitalization exceeding 3000 billion USD.

In terms of market structure, stablecoins exhibit high concentration and dollar dominance. By number, USD-pegged stablecoins account for about 64%; by market capitalization, USD stablecoins account for as high as 98%, with USDT and USDC dominating the market, while stablecoins pegged to other currencies are minimal in scale. Regarding reserve assets, mainstream fiat-pegged stablecoins use US short-term Treasury bonds, reverse repurchase agreements, and cash equivalents as core reserves. Some issuers lack sufficient transparency and auditing, still posing potential redemption risks.

Current stablecoin applications remain primarily within the crypto ecosystem, acting as the pricing and settlement medium for crypto asset trading, and as collateral in decentralized finance (DeFi) lending and liquidity protocols. Excluding high-frequency trading, wash trading, and other automated nominal volumes, the actual transaction volume is only about 1% of the nominal size. Retail scenarios (single transactions below 250 USD) account for less than 0.9%. Cross-border remittances, retail payments, and other real economy scenarios are still in the early pilot stage. However, in emerging markets with high inflation and volatile exchange rates, stablecoin cross-border flows are continuously increasing, becoming a hidden channel to evade currency depreciation and bypass capital controls.

Operational Mechanism: A New Offshore US Dollar Vehicle

Stablecoins operate on an "on-chain circulation + off-chain reserve" model: the issuer collects fiat currency at a 1:1 ratio and mints tokens, users hold them via digital wallets, and leverage public blockchains for 24/7 global transfers, with reserve assets used for redemption to maintain the peg. This model combines features of 19th century private banknotes, the Eurodollar market, and money market funds (MMF). In essence, they are on-chain private claims on offshore US dollars, extending dollar liquidity through financial innovation.

Unlike the traditional Eurodollar market, stablecoins lack bank credit elasticity and central bank liquidity support. Their stability relies entirely on the quality of reserve assets and market arbitrage mechanisms. The collapse of TerraUSD in 2022 and the temporary de-pegging of USDC in 2023 demonstrate that stablecoins without sufficient, highly liquid reserves are prone to losing their peg under stress. There is now a global regulatory consensus: focusing on regulating fiat-collateralized stablecoins and rejecting algorithmic stablecoins.

Regarding risk transmission, stablecoin reserves are heavily concentrated in US short-term Treasury bonds, creating a transmission chain of "global demand → stablecoin issuance → increased holdings of US Treasuries," directly affecting US Treasury yields and the transmission efficiency of Federal Reserve monetary policy.

Global Impact: Exacerbating Monetary Hierarchy Divisions, Challenging Monetary Autonomy in Emerging Markets

Utilizing the Cohen-Kenen international monetary function framework, the report systematically assesses the impact of stablecoins on the international monetary system from three core functions (unit of account, medium of exchange, store of value) and two sectors (private and official). The conclusions show that stablecoins have the most direct impact on the store of value and medium of exchange functions in the private sector, with limited impact on the unit of account and official sector functions, but they can implicitly constrain monetary policy autonomy.

  • 1. Store of Value: Core Channel for Digital Dollarization In high-inflation emerging markets, USD stablecoins, which require no foreign currency account and can be held cross-border anonymously, have become the preferred safe haven for residents, leading to "invisible dollarization". Stablecoin inflows are highly correlated with local currency depreciation and widening exchange rate differentials, crowding out local currency deposits and weakening central banks' regulatory capacity.

  • 2. Medium of Exchange: Enhancing Cross-Border Payment Efficiency Stablecoins offer advantages such as real-time settlement, no business hour restrictions, and low fees, and are rapidly penetrating cross-border remittance and e-commerce scenarios. Their development further reduces friction in using the US dollar, expanding its share in retail cross-border payments and e-commerce transactions.

  • 3. Unit of Account: Limited Impact, Hard to Break Commercial Inertia Trade invoicing and contract pricing have strong path dependence. Stablecoins have not yet changed the global trade pattern denominated in US dollars and euros. They are only sporadically used in some retail scenarios in high-inflation economies and have not formed systemic substitution.

  • 4. Official Sector: Indirect Constraints, No Direct Substitution Central banks have not yet incorporated stablecoins into foreign exchange reserves or as exchange rate intervention tools; the official unit of account and intervention functions have not been directly impacted. However, widespread private sector use of stablecoins can lead to ineffective capital controls and impeded monetary policy transmission, exacerbating the "trilemma": financial openness is passively increased, intensifying the conflict between exchange rate stability and monetary policy autonomy.

Three Future Scenarios: From Limited Penetration to Systemic Transformation

Based on adoption scale, regulatory environment, and cross-border impact, the report constructs three mutually exclusive yet parallel future scenarios, covering possible paths from marginal influence to reshaping the system for stablecoins.

  • Scenario 1: Niche Adoption (Baseline Scenario) Stablecoins remain confined within the crypto ecosystem, with limited penetration into the real economy. Partial holding occurs in high-inflation countries, while retail payments and trade settlement remain primarily in local currencies. Regulation focuses on anti-money laundering and consumer protection. Capital flow spillover is small, monetary sovereignty and financial stability in emerging markets are largely controllable, and central banks retain full policy autonomy. This scenario aligns closely with current market characteristics and is the most likely short-term trajectory.

  • Scenario 2: Digital Dollarization (High-Risk Scenario) USD stablecoins become the de facto standard for cross-border retail payments and domestic pricing in emerging markets, banks provide related services, and deposit dollarization accelerates. Local currency policies become ineffective, capital controls are rendered meaningless, domestic savings flow into US Treasuries via stablecoins, and the domestic credit market shrinks. Exchange rate transmission effects intensify, stablecoin run risks directly impact financial stability in emerging markets, creating irreversible digital dollar dependence. This scenario poses a far greater threat to monetary sovereignty than traditional dollarization and is an extreme risk emerging markets must guard against.

  • Scenario 3: Integration of Local Currency Stablecoins (Ideal Scenario) Through regulatory authorization, emerging markets allow licensed institutions to issue local currency stablecoins, interconnected with domestic fast payment systems and central bank digital currencies (CBDC). Reserve assets are limited to local currency government bonds and central bank deposits, balancing technological efficiency with policy autonomy. Stablecoins are used for government payments, e-commerce settlement, and securities clearing, enhancing payment efficiency and financial inclusion while avoiding foreign currency substitution risks. However, this scenario requires sound regulatory capacity, financial infrastructure, and macroeconomic stability, conditions which most low-income emerging markets currently lack.

Regulatory Challenges and Policy Implications: Global Coordination is Key

The cross-border nature of stablecoins determines that single-country regulation is difficult to be effective. The report proposes four core policy directions:

  • 1. Unify Global Regulatory Standards: Implement the Financial Stability Board (FSB) recommendations on stablecoin regulation, clarifying reserve requirements, disclosure rules, and redemption mechanisms to avoid regulatory arbitrage.

  • 2. Strengthen Cross-Border Collaboration: Establish regulatory information sharing and risk resolution mechanisms between issuing and using countries to address cross-border runs and capital flow shocks.

  • 3. Upgrade Domestic Defenses: Emerging markets should improve macroeconomic stability, optimize domestic payment systems, and advance CBDC development to counter the appeal of foreign currency stablecoins.

  • 4. Prevent and Control Illegal Activities: Utilize blockchain traceability technology to combat money laundering, terrorist financing, and other abuses, balancing innovation and risk.

In summary, stablecoins are not simple financial innovations but structural forces reshaping the international monetary hierarchy. In the short term, they may reinforce dollar hegemony and exacerbate the financial subordination of emerging markets; their long-term impact will depend on global regulatory coordination, innovation in local currency digital tools, and market adoption paths. For emerging markets, stablecoins are a double-edged sword of both opportunity and risk: they can enhance payment efficiency and promote financial inclusion, but may also trigger digital dollarization and erode monetary sovereignty.

The future global monetary system will enter a new stage of coexistence between public digital currencies (CBDC) and private digital currencies (stablecoins), and competition between fiat currencies and digital dollars. Only through sound macroeconomic policies, robust regulatory frameworks, and international coordination can we embrace the benefits of technology while safeguarding financial security and monetary sovereignty, avoiding falling into a new type of digital financial subordination.

QAccording to the BIS report, what is the dominant characteristic of the stablecoin market in terms of currency pegs and market concentration?

AThe stablecoin market is highly concentrated and overwhelmingly dominated by the US dollar. As of 2026, US dollar-pegged stablecoins account for 64% of the total number of stablecoins and a staggering 98% of the total market value. USDT and USDC are the dominant players, with stablecoins pegged to other currencies having minimal scale.

QHow does the BIS report describe the operational mechanism of stablecoins, and what historical financial innovations does it compare them to?

AStablecoins operate on a 'on-chain circulation, off-chain reserves' model. This mechanism is described as combining features of 19th-century private banknotes, the Eurodollar market, and money market funds (MMFs). Essentially, they represent a private claim on US dollars in an offshore context, extended onto the blockchain as a new form of liquidity.

QWhat is the 'high-risk scenario' (Scenario 2) outlined in the BIS report regarding the future of stablecoins?

AThe high-risk scenario, termed 'Digital Dollarization,' describes a situation where US dollar stablecoins become the de facto standard for cross-border retail payments and domestic pricing in emerging markets. This leads to accelerated dollarization of deposits, renders domestic monetary policy and capital controls ineffective, and could cause domestic savings to flow into US Treasuries via stablecoins, shrinking local credit markets. It poses an extreme threat to monetary sovereignty.

QAccording to the report, what is the 'ideal scenario' (Scenario 3) for emerging markets to mitigate risks from foreign currency stablecoins?

AThe ideal scenario is the 'Integration of Local Currency Stablecoins.' This involves emerging markets authorizing licensed institutions to issue local currency stablecoins. These would be interoperable with domestic fast payment systems and CBDCs, with reserve assets restricted to local currency bonds or central bank deposits. This approach aims to harness technological efficiency while preserving monetary policy autonomy and avoiding foreign currency substitution risks.

QWhat are the four core policy directions recommended by the BIS report to address the challenges posed by stablecoins?

AThe four core policy directions are: 1) Unify global regulatory standards (implementing FSB recommendations). 2) Strengthen cross-border cooperation for information sharing and risk management. 3) Upgrade domestic defenses in emerging markets (improve macroeconomic stability, domestic payment systems, and CBDCs). 4) Prevent illicit activities by leveraging blockchain traceability to combat money laundering and terrorist financing.

Can DeepSeek Save China One Trillion Dollars?

"DeepSeek and the $1 Trillion Infrastructure Question" The article examines whether DeepSeek's AI optimization breakthroughs could potentially save China $1 trillion in future AI infrastructure costs. The analysis begins with Nvidia's upcoming Vera Rubin AI platform, costing ~$7.8 million, where memory (HBM4/LPDDR5X) constitutes $2 million—a 435% cost increase in one year, highlighting how AI hardware spending is shifting toward expensive memory components. DeepSeek's approach works in the opposite direction. Through three key technical innovations showcased in DeepSeek V4, the company dramatically improves hardware efficiency: 1. **Memory Compression (MLA)**: Re-engineers the attention mechanism to compress long-context memory (KV Cache) by over 90%, drastically reducing expensive HBM usage. 2. **Selective Activation (MoE)**: Employs Mixture-of-Experts architecture where only a small fraction of parameters (e.g., 49B out of 1.6T in V4-Pro) are activated per token, allowing most parameters to reside in cheaper memory/SSD. 3. **Computation Caching**: Reuses previously computed results via cache hits, replacing expensive GPU computations with cheap memory reads. Combined, these optimizations allow the same hardware to produce approximately 4x more tokens, effectively reducing required hardware investment by 75%. DeepSeek's pricing reflects this: a 10-billion token workload costs ~$522 monthly versus ~$9,000-$10,000 for competitors. The $1 trillion savings projection stems from McKinsey's estimate that global AI infrastructure will require ~$5.2 trillion investment by 2030. As China's daily token consumption grows toward quadrillions, even marginal efficiency gains scale massively. With a conservative 4x throughput improvement, China could avoid building tens of thousands of AI data centers equivalent to ~7 trillion RMB ($1 trillion) in saved investment. Critically, this strategy shifts dependency from scarce, expensive GPU/HBM—where China lags—toward more accessible storage, caching, and systems engineering where domestic suppliers like CXMT are gaining strength. Rather than "replacing Nvidia," DeepSeek rebalances AI's value chain away from monolithic hardware dependency. Ultimately, DeepSeek's technical breakthroughs could lower the barrier to AI adoption across Chinese industries by making advanced capabilities affordable at scale—transforming who can access next-generation AI.

Overturning the Mainstream Approach to Hallucinations: Metacognition is the New Solution for Large Models to Break the Hallucination Barrier

This paper, "Hallucinations Undermine Trust; Metacognition is a Way Forward," proposes a paradigm shift in combating AI hallucination. It argues that the current mainstream approaches—striving for omniscience by scaling data/models or having AI abstain from uncertain answers—are fundamentally flawed. The former has inevitable knowledge gaps, while the latter imposes a crippling "utility tax," requiring the rejection of many correct answers to achieve high accuracy, due to models' poor "discrimination" (the ability to distinguish correct from incorrect answers internally). The core contribution is redefining hallucination not as "being wrong," but as "expressing false information with unwarranted certainty." The proposed solution is **Faithful Uncertainty** or **Metacognition**: enabling AI to accurately perceive its internal uncertainty and honestly express it in its language (e.g., using hedging phrases when unsure). This creates a more reliable assistant that provides useful information while signaling its confidence, minimizing harm from errors. The paper emphasizes that metacognition is critical for the era of AI Agents. Without it, Agents cannot intelligently decide when to use tools like search engines, leading to inefficiency and misuse. Key implementation challenges are highlighted: the "bootstrapping paradox" of training with static uncertainty data, the "alignment distortion signal" where human preference training suppresses internal uncertainty cues, and the difficulty of causally evaluating true metacognition vs. its superficial imitation. The paper concludes that the goal should not be an infallible AI, but one that is honest about the limits of its knowledge, thereby building user trust through transparent communication of its certainty.

Hedge by Buying Gold and Oil, Chase Soaring Returns with AI. ‘Dated’ Bitcoin Enters a Bear Market

Bitcoin has recently declined, hitting a two-month low near $66,123, while Ethereum fell to a three-month low around $1,837. Analysts suggest the drop is not merely due to factors like ETF outflows or MicroStrategy's selling but reflects a deeper issue: Bitcoin is losing a broader asset competition. In a near-zero interest rate environment, Bitcoin previously thrived as an outlet for investor dissatisfaction with inflation and limited options. However, the market landscape has shifted. Bitcoin now occupies an "awkward middle ground," facing competition on three fronts. For inflation hedging, investors prefer gold, energy stocks, and commodity producers—assets with tangible backing and clearer pricing power. For growth exposure, AI-related companies with actual revenues and profits are more attractive. Even within crypto, investors can choose stablecoins, exchanges, or infrastructure firms tied directly to adoption, offering clearer business models and leverage. Thus, Bitcoin is no longer the top choice for hedging, growth, or crypto exposure. This shift is evident in market reactions: despite recent warnings about persistent inflation from a Fed official, Bitcoin did not rally as it might have in the past. Instead, capital flowed to assets with direct commodity or energy exposure. The recent ETF outflows and MicroStrategy sales are symptoms, not causes, of this new reality. Investors are becoming more selective, demanding clearer value propositions beyond mere scarcity. The emerging bear case for Bitcoin is not about it being a bubble or failed technology, but that scarcity alone is no longer sufficient.
