「一石激起千层浪」的市场，以不变应万变

波涛汹涌的链上，DeFi 正直接迎战。

撰文：Pzai，Foresight News

昨日，随着全球市场经历巨大震荡，加密市场也没能独善其身。而在链上，仅以太坊生态上就创下单日清算超 3.5 亿美元的记录。市场的「一波」正在激发 DeFi 的「万波」，而 DeFi 项目是如何应对的？海啸退去之时又是谁在裸泳？故笔者撰写本文对 DeFi 在市场波动下的表现进行总结。

稳定币

在 Ethena 方面，昨日其稳定币 USDe 创下单日流出 9580 万美元的记录，总供应量也从巅峰时期的 36 亿枚回落至 31 亿枚左右。由于 Ethena 的机制导致多头头寸必须保持在较高水平，随着市场的下跌，抵押物的潜在清算导致用户需要控制风险，继而赎回相关代币。

另外 Blast 上稳定币 USDB 在昨日短时脱锚至最低 0.937 美元。由于 Blast 的稳定币生态相对封闭，且 Blast 链启动初期项目方对 USDB 的激励较大，导致市场波动时资金流出的影响较大。现在 USDB 已经基本回锚。

借贷协议

就清算情况而言，8 月 5 日的清算情况最为严重，整体规模超过 3.5 亿美元。按协议分配来看，Aave V3 的清算额最大，达到 2.5 亿美元。其次是 Compound 清算，总清算额达 7960 万美元。在 Aave V3 的清算中，主要集中于以太坊的大类资产清算，前三名分别为 WETH、wstETH 和 WBTC。

在市场波动中，Aave 也获得了超过 600 万美元的收入。

清算完成后，链上整体的清算线已经低于 2000 美元。在清算中，由于机制特性，在市场波动较大时容易出现坏账，如 Aave V3 近七天内共产生了 35 万美元的坏账。相比之下，Curve Llamalend 因为其软清算机制避免了大部分硬清算，其中软清算在 8 月 5 日承担了 5024 万美元的清算份额。

整体而言，借贷协议对本次市场波动的应对还算差强人意。

去中心化交易所（DEX）

在 Uniswap V3 中，8 月 5 日达到最高峰值 8.4 亿美元，并为 LP 产生了 111.9 万美元的费用。

GMX 方面，8 月 5 日当天，持有头寸较前日下降了 30% 左右，并清算了 830 万美元的资产，主要以 USDC 为主。

再质押

再质押资产作为现今以太坊的核心资产之一，市场波动下的流出也比较显著。例如 Renzo 的质押通证 ezETH 最低脱锚至 0.876 WETH 点位。

协议流出上，以 ether.fi 为例，8 月 5 日全天就提现了 79013 枚 ETH，总价值超过 1 亿美元，其中大部分是 Eigenlayer 的 eETH 提现。凭借着超过 7.7 万枚 ETH 的流动性和 73% 以上的 DeFi 利用率，协议不存在整体上的挤兑风险。

整体而言，Lido stETH 提现队列没有大幅增长的态势，且链上主要的 LST 一直保持稳定。所以整体上再质押生态没有系统性风险。

Report Interpretation: J.P. Morgan Details Micron's Pre-Earnings Sentiment, Current Hardware Sector Dynamics

Morgan Stanley analyst Joshua Meyers' report (June 21, 2026) highlights key trends in the hardware and semiconductor sector ahead of Micron's earnings. The core takeaways are: 1. **Micron & Memory:** Memory remains a high-conviction long theme, driven by strong AI demand and rising ASPs. However, investor focus is shifting to the sustainability of Micron's >80% gross margins and the specifics of potential new long-term supply agreements (SCAs). 2. **Hardware Supply Chain:** AI-related demand for servers, networking, and storage remains robust, but company performance is diverging. Celestica (CLS) shows improved margin confidence, Western Digital and Seagate benefit from pricing, Fabrinet (FN) sees predictable AI optics growth, and Teradyne (TER) anticipates a new Google customer. 3. **AI Capex & WFE Forecasts:** JPMorgan increased its Wafer Fab Equipment (WFE) market growth forecasts to 28% in 2026 and 29% in 2027. AI infrastructure financing is evolving, with higher project-level debt reducing constraints on capex expansion. The report signals that while the AI-driven hardware cycle is strong, the market is entering a phase focused on execution verification (e.g., Micron's SCA details, Fabrinet's ramp with Amazon) and valuation sustainability. Key near-term signals include Micron's guidance, Arista Networks' outlook, and the pace of demand normalization post potential tariff-related pull-ins.

Research Report Analysis: The Fed's New Chair's Debut – New Leader, But Same Script?

Report Analysis: Federal Reserve's New Chair Debut – A New Captain, But the Same Script? Morgan Stanley's chief global economist Seth B. Carpenter analyzes the first FOMC meeting under new Fed Chair Kevin Warsh in a June 21 report. Warsh deliberately avoided providing forward guidance on interest rates, aligning with his philosophy. However, market expectations for a rate hike this year were reinforced. Key signals lie elsewhere: inflation may fall more than expected, and quantitative tightening (QT) could be more aggressive than anticipated. The FOMC's "dot plot" suggests only one rate hike in 2026. Carpenter argues that if inflation undershoots forecasts, the logic for even a single hike weakens, especially as projections indicate potential rate cuts in 2027. On QT, Warsh's stance is clear. Carpenter notes that measures like halving the Treasury's account balance could shrink the Fed's balance sheet by around $500 billion with minimal market impact. Combined with adjustments to reserve interest and liquidity rules, the ultimate QT scale may exceed expectations, though its market effect might be less disruptive unless the Fed actively sells Mortgage-Backed Securities (MBS). While Warsh initiated a review of the Fed's policy framework, the 2% inflation target remains intact for now. The report concludes that the market may be overestimating the significance of reduced forward guidance and the near-term rate hike risk, while potentially underestimating the scope and manageable nature of the coming balance sheet reduction. The key debates will hinge on upcoming core PCE data, the specifics of the QT path, and the framework review's findings.

Critical Game Week: BTC Retracement Confirmation vs. HYPE Support Battle | Guest Analysis

This weekly analysis outlines a critical juncture for BTC and HYPE markets, focusing on key price level confirmations. **BTC Analysis:** BTC is at a pivotal point after a five-wave rally from the June 5th low of $59,100. The price has broken below a short-term rising channel's lower boundary, with the current move seen as a pullback to test this breakdown. Failure to reclaim this level could lead to a retest of the $59,000-$60,000 support zone. The core scenario hinges on this channel retest outcome. * **Key Levels:** Resistance at $64,500-$65,000 (channel boundary) and $69,500-$70,500. Support at $59,000-$60,000 and $55,000. * **Strategy:** A core bearish stance is maintained (20% short from last week), with short-term plans for tactical trades. Three detailed contingency plans (A/B/C) are provided for short positions on resistance tests or breakdowns, emphasizing strict stop-loss discipline. **HYPE Analysis:** HYPE shows strong momentum but is currently in a corrective phase after hitting a new high of $76.94. The price is retesting the crucial $64-$66 support area. * **Key Levels:** Resistance near $77 and $80-$82. Support at $64-$66 and $52-$54. * **Strategy:** The short-term approach is "buy on dips, avoid chasing rallies." A long position is considered only if clear stabilization signals appear at the $64-$66 or deeper $52-$54 support zones, with tight risk controls. **General Risk Management:** A standardized trailing stop-loss protocol is emphasized: set initial stop, breakeven at +1% profit, then trail stops upward to lock in gains. *Disclaimer: All analysis is presented as a personal trading framework, not investment advice. Market conditions are complex and require dynamic adjustment.*

Research Report Interpretation: Citi Attends AWS Summit, Bullish on Cloud Business Acceleration but Data Governance Remains Key Variable

Citi analyst Tyler Radke's team attended the AWS New York Summit (June 17-18), engaging with over 10 clients and partners. In a June 19 report, they highlighted the summit's focus on scaling agent AI for enterprise deployment. Citi maintains a "Buy" rating on Amazon, forecasting AWS revenue growth to accelerate to 37% in FY27 from 30% in FY26, noting this estimate may be conservative. Key takeaways: 1. **AWS Strategy Shift:** AWS is moving from proof-of-concepts to scalable deployment. New offerings like AWS Context (building enterprise knowledge graphs), Amazon Quick (cross-application AI assistant), and security tool Continuum address core enterprise pain points for AI adoption. 2. **Data Infrastructure Beneficiaries:** Data infrastructure companies like Snowflake, Elastic, Oracle, and ClickHouse are seen as direct beneficiaries of scaling AI workloads, as evidenced by strong growth and use cases presented. 3. **Critical Role of Data Governance:** As AI agents scale from hundreds to thousands, effective data governance becomes the key variable for deploying AI in core business processes. AWS Context represents AWS's strategic extension from providing compute/models to offering a data governance infrastructure layer. The report emphasizes that without solving data governance, AI will remain confined to pilot projects. The investment thesis focuses on AWS revenue acceleration and data infrastructure vendors' growth, while monitoring signals like AWS's quarterly revenue growth, Bedrock AgentCore task volume, and pricing impacts on companies like Elastic.

Crucial Week of Contention: BTC Tests Support and HYPE's Key Level Battle | Special Analysis

**Market Enters Critical Week: Bitcoin Pullback Test and HYPE Support Battle** The market enters a crucial phase of contention this week. The marginal shifts in Federal Reserve policy expectations continue to dictate the pricing rhythm for risk assets. Meanwhile, in the crypto market, following a period of sideways consolidation, the divergence between bulls and bears is becoming concentrated at key price levels. **Bitcoin (BTC) Analysis & Strategy** * **Technical View:** The 4-hour chart suggests BTC is in a five-wave structure since the June 5th low near $59,100. Price action shows a short-term rising channel. The recent drop below this channel's lower boundary is now being followed by a pullback attempt (wave 40-41). The outcome of this retest is critical. * **This Week's Outlook:** The core focus is whether BTC can reclaim and hold above the channel's lower boundary. * **Bullish Scenario:** A successful hold could lead to a continued rebound, potentially challenging the $69,500 - $70,500 resistance zone. * **Bearish Scenario:** Failure to hold may trigger a renewed test of the $59,000 - $60,000 core support area, with $55,000 as a deeper support level. * **Operational Strategy:** The author maintains a 20% mid-term short position initiated last week near $64,500, based on a model signaling a shift to a bearish structure. Short-term tactics involve using 30% capital for potential "spread" trades, with three contingency plans (A, B, C) outlined for reacting to resistance tests, breakouts, or support breakdowns. **HYPE Analysis & Strategy** * **Technical View:** On the 4-hour chart, HYPE shows strong momentum, having recently broken to a new high since January. The current pullback presents a clear three-wave correction structure, bringing the price back to the critical $64 - $66 support zone. * **This Week's Outlook:** The focus is on the battle for the $64 - $66 support area. * **Bullish Scenario:** Holding this support could signal a continuation of the uptrend from the June 10th low, leading to new highs. * **Bearish Scenario:** A breakdown could extend the correction, potentially testing the deeper $52 - $54 support band. * **Operational Strategy:** The recommended short-term approach is "buy on dips, avoid chasing rallies." A light long position (under 30% capital) could be considered if HYPE shows stabilization signals at the $64-$66 or $52-$54 support zones, confirmed by model signals. Strict stop-loss discipline is emphasized. **General Risk Management:** A strict trailing stop-loss protocol is advised: set an initial stop; move to breakeven at +1% profit; lock in profits progressively thereafter. *Disclaimer: All analysis is presented as the author's personal technical perspective and trading log, not as investment advice. Markets are complex and dynamic; risk control is paramount.*
