为什么每轮美联储降息市场都会动荡?

币界网报道:

近期,加密市场表现出极大的谨慎态度,甚至连ETF资金流动都显得十分冷清,圈内资金状况更为不佳,二级市场的表现也因此非常疲软。StarEx认为,这种现象主要源于对美联储降息前景的担忧。理论上,降息意味着流动性改善,通常会推动资本市场上涨。但为什么每次美联储进入降息周期的初期,市场却往往出现大幅下跌,甚至引发金融危机呢?

这可以从市场结构的角度进行分析。经历了一轮美元加息后,由于美元收益率高于其他地区,且美元资产的风险较低,全球资金自然会大量流入美国。在正常情况下,资金存放在任何地方都会产生利息,而借贷资金则会产生成本。因此,单纯依靠利率差获取收益相对有限。为了追求更高收益,资本往往会扩大规模,这就需要通过加杠杆进行借贷。换句话说,每次美元加息后,市场中的杠杆率都会大幅提高。

资本运作的核心在于安全性和收益率。自2022年以来,美联储的加息速度和幅度达到近几十年来的最高水平,且全球局势动荡不安,各类争端和冲突不断,因此资本涌入美国的动力异常强劲。这也解释了过去一年多来,在加息和缩表的背景下,美股和加密市场依然持续上涨的原因。

进入降息周期后,套利结构的利润空间逐渐缩小,资本不得不抛售资产以偿还债务,这便导致了资产价格的下跌。如果此时经济出现衰退,市场进一步陷入恐慌性抛售,可能会演变成一场金融危机。2000年的互联网泡沫和2008年的次贷危机,都是在美联储开始降息后发生的。在这种情况下,美联储降息越快,市场杠杆的崩溃速度也就越快,危机的程度也就越深。

前段时间,市场的剧烈波动一度引发了华尔街的恐慌,金融市场正在释放经济衰退风险上升的信号。尽管这一风险仍然较小,但根据高盛集团和摩根大通的模型预测,从美国债券市场的表现以及对商业周期高度敏感的股票走势来看,市场隐含的经济衰退概率已经显著上升。高盛指出,股票和债券市场预计美国经济衰退的可能性已从4月份的29%上升至41%。这一增幅主要源于市场预期美联储将更为激进地降息,以及商业周期敏感型股票表现不佳。摩根大通的模型也显示,由于美国国债大幅重新定价,经济衰退的可能性已从3月底的20%上升至31%。

日元加息以及美国发布低于预期的失业率数据,都引发市场的极度恐慌,美股、日股和加密市场因此大幅下挫,市场担心美国经济可能陷入衰退甚至萧条。鉴于2000年和2008年的教训,美联储在应对危机时已经更加有经验:直接启动印钞机购买资产,这就是所谓的量化宽松政策。2008年和2020年市场暴跌也是通过这种方式应对的。

然而,这种策略会导致一个严重的问题,即债务规模迅速膨胀,严重侵蚀法币的信用。如今,美联储的债务规模已超过35万亿美元。如果每次危机都通过印钞救市,债务规模终有一天会达到无法承受的地步,进而引发超级通胀。随着美元降息的临近,流动性很可能开始收紧。接下来,市场需要观察美国是否会陷入经济衰退。如果衰退发生,美联储是否会再次开启印钞机救市?

StarEx认为降息的第一阶段可能会带来“温和”的市场下跌;如果经济确认进入衰退,市场可能会出现危机式下跌;而在美联储大规模注入流动性后,市场又可能出现强劲反弹。本质上,根源还是法币的持续贬值。

Bitcoin at 59,000 Is Not the Bottom, One Last Drop Needed! Chain Data and Liquidity Analysis: Where is BTC's True Bottom?

Based on analysis by trader Mr. Beggar, Bitcoin's (BTC) recent low of $59k is likely not the final cycle bottom. He argues that while a bottom is near, a final downward movement is still probable to target liquidity below that level, making a deeper low healthier for a sustainable reversal. Mr. Beggar's framework combines on-chain data for long-term cycles and liquidity-based technical analysis for shorter-term trades. His "four deep bear buying models" include Cointime Price (market cost weighted by coin holding time) and AVIV (an enhanced MVRV indicator), which currently suggest prices are nearing cyclical bottom zones. While a PSIP (Percent Supply in Profit) signal has flashed below 50%, it alone is not considered definitive; typically, the first signal is not the final bottom. He presents three potential scenarios for the current market: 1) a direct drop from here, 2) an upward liquidity sweep (stop hunt) of the recent high near $67.3k before declining, and 3) a direct reversal without new lows. He heavily discounts the third scenario due to significant un-swept liquidity in the $59k-$62.3k range, suggesting the market must revisit these levels. Mr. Beggar shares that he used on-chain signals to identify potential cycle tops in late 2024/early 2025 and later established low-leverage BTC-denominated short positions. He emphasizes the importance of risk management and staying within one's expertise ("strike zone"), warning against investing in assets like AI/semiconductor stocks simply because they are rising.

From Signal Monitoring to Strategy Copy Trading: How PPP Lowers the Barrier to Trading on Polymarket?

From Signal Monitoring to Strategy Copy Trading: How PPP Lowers the Barrier to Polymarket Trading The surge in trading demand on prediction markets like Polymarket, especially during events like the World Cup, exposes a common challenge for novice users: emotional and impulsive trading due to a lack of stable strategies and reliable signals. Prediction Position Platform (PPP) addresses this by serving as a Telegram-based tool for strategy discovery and automated copy-trading on Polymarket. PPP offers a suite of features through a subscription model. Key functionalities include 24/7 market signal monitoring (tracking smart money movements and rapid probability shifts), an "AI Address Analysis" tool to evaluate trader performance metrics, and specialized sections like a "World Cup Zone" for quick access to related markets. Its core value lies in two curated lists: the "Strategy Square," which identifies addresses suitable for long-term tracking based on comprehensive metrics like returns, win rate, and drawdowns, and the "Trading Leaderboard," highlighting recently outperforming addresses for short-term opportunities. Users can manually analyze any address or set up automated copy-trading with customizable parameters like investment amount and stop-loss. After initiating copy-trades, users can manage all positions from a unified dashboard, adjusting parameters or stopping follows as needed, and review historical performance data. Crucially, PPP employs a non-custodial wallet model, meaning user funds remain in their own self-custodied wallets, enhancing security and trust. In summary, PPP aims to reduce the learning curve and trial-and-error cost for Polymarket users by aggregating signals, curating and analyzing profitable traders, and facilitating automated, yet manageable, copy-trading execution.

From the White-Haired Stock God to the Billion-Dollar Fund Titan: The Smart People Shorting NVIDIA Are Getting Rich Using the Same Framework

From "white-haired stock god" to billionaire fund manager, those profiting from shorting NVIDIA share a common framework. The article analyzes the critical bottlenecks in the AI hardware supply chain, which have become key investment focal points. The core argument is that the real constraint on the AI boom isn't software or algorithms, but fundamental physical infrastructure. The piece dissects nine major bottlenecks, organized around the lifecycle of an AI accelerator circuit board. *Before the Board*: The pre-manufacturing stage faces constraints in EDA tools, new materials (like GaN, SiC, InP) replacing silicon, and the critical, non-renewable supply of helium for semiconductor fabrication. *On the Board*: The primary bottlenecks are High-Bandwidth Memory (HBM), essential for unleashing GPU power, and advanced packaging (e.g., CoWoS), required to integrate components. Both are in severe shortage. *Between Boards*: Chip-to-chip communication is hitting limits with copper, pushing photonics and optical interconnects (CPO) as the next-gen solution, with NVIDIA heavily investing in this area. *Around the Board*: Power delivery requires new materials (GaN/SiC) for efficient voltage conversion from 48V to sub-1V. High-density AI racks (120kW+) are forcing a shift from air to liquid cooling as the standard. *Beyond the Board*: The ultimate bottleneck is electricity. AI data centers consume power equivalent to mid-sized cities, and grid expansion lags far behind demand, causing project delays and a scramble for power contracts. Prominent investors like Leopold and "white-haired stock god" are heavily betting on these infrastructure bottlenecks. Leopold's fund, for instance, holds no NVIDIA stock but uses massive put options to short the semiconductor sector while going long on power and physical infrastructure. His thesis is that while chip competition may eventually erode margins, the scarcity of foundational elements like electricity is more persistent. The framework's validity is tied to the supply-demand gap. Major new capacity in HBM and photonics is scheduled for 2027-2028, but demand continues to outpace it. Experts like Intel's CEO suggest no relief before 2028. However, the article warns of a potential reversal around 2028-2029 if AI capex slows and new capacity floods the market, turning scarcity into oversupply. Until then, the imbalance persists.
