Wednesday, the Fed's dot plot showed half of the officials projecting a rate hike within the year. Walsh announced the abandonment of forward guidance during the press conference, triggering a decline of over 1% across all major indices, erasing gold's gains for the week, and sending the dollar to a two-month high. The optimism from Monday failed to last three days, thoroughly liquidated by the hawkish dot plot and a new chair who refused to offer policy signals.

Market Performance

The S&P 500 closed down 1.21% at 7,420.10 points, the Nasdaq fell 1.34% to 26,021.66 points, the Dow Jones lost 0.97% to 51,492.55 points, and the Russell 2000 dropped 0.74%. All four major indices fell in sync, marking the largest single-day decline so far this three-day week. The market remained restrained for most of the session, dipping only slightly upon the release of the FOMC statement. The real sell-off concentrated in the first thirty minutes of Walsh's press conference, with the S&P 500 plunging nearly 0.8% in a one-way slide and never recovering, as the indices closed near their daily lows.

SpaceX closed down about 5% at $191, marking its first drop since its IPO. After three consecutive days of hitting new highs, valuation pressure from the hawkish dot plot finally caught up with this stock with a market cap nearing $2.7 trillion. Option-implied volatility rose accordingly, formally ending the post-IPO honeymoon period.

Meta dropped over 5% to $586.20, leading the decline among the "Magnificent 7" tech giants, with Alphabet, Amazon, and Microsoft also falling. The entire Mag 7 faced unified pressure under the new interest rate framework, as the pricing logic for high-valuation tech stocks is being forcibly reset by hawkish expectations. The tech sector accounted for the majority of the Nasdaq's decline for the day.

The Philadelphia Semiconductor Index (SOX) bucked the trend to close up 1.38%, the only bright spot of the day. Applied Materials rose 9.3% to $214.60, Lam Research gained 6.6% to $97.40, and Arm Holdings climbed 6.2% to $182.30. Their logic was consistent: the long-term thesis of AI computing power demand remains intact despite interest rate shocks, with funds flowing out of interest-rate-sensitive software and internet stocks and finding buyers in the equipment and infrastructure layer.

Consumer Staples and Utilities, two defensive sectors, led the declines. Their valuations have long been supported by low interest rates, making them prime targets for repricing under renewed rate hike expectations. The rotation of funds from defense sectors to the earnings-supported computing power chain was the clearest directional shift of the day.

Macro & Outlook

The dot plot was the core event of the day. Among 18 officials, 9 projected at least one rate hike within the year, with 5 expecting two hikes and 1 expecting three. Only 1 official still projected a rate cut. The median projection for the end-2026 rate was sharply raised to 3.8% from 3.4% in March, formally signaling the end of the easing cycle. The statement was shortened by two-thirds, removing all interest rate guidance and leaving only a single sentence at the end: "committed to achieving price stability." This was the first unanimous vote on the policy statement in nine months.

During the press conference, Walsh stated, "I can't tell you what the next step is going to be," announcing the abandonment of forward guidance, while also reportedly not submitting a dot plot. This led to speculation that this might be the last dot plot. Trump, at the G7, called Walsh "very excellent" and said the idea of raising rates was "unbelievable," but he would listen to Walsh's wishes. The tension between the White House and the Fed has not dissipated, merely temporarily overshadowed by the hawkish shock of the dot plot.

May Retail Sales rose 0.9% month-over-month, hitting a three-year high. Last week's EIA crude oil inventories plummeted by 8.26 million barrels, far exceeding expectations, with Cushing stockpiles falling to a decade low. The combination of these two data points makes the expectation of persistently high inflation even harder to shake and makes any dovish stance more difficult to sustain.

The VIX jumped 12%, breaking above 18. The 2-year Treasury yield surged 13 basis points to 4.18%, while the 10-year yield rose about 7 basis points to 4.49%. Traders have now fully priced in a rate hike before October, with September seen as highly likely, and cumulative hikes of two times are expected before the first quarter of next year.

The dollar surged 0.86% to a two-month high. Gold fell 1.64% to $4,258 per ounce, with silver dropping nearly 3% in sync. Bitcoin (CoinGecko) fell to the $64,100 range, and Ethereum weakened to around $1,760. Crude oil settled flat near $76 after wild swings.

The US-Iran Memorandum of Understanding has been signed remotely, with the formal signing ceremony scheduled for June 19th in Switzerland. However, Trump explicitly stated that military action would be restarted if Iran fails to comply, leaving the timeline for reopening the Strait of Hormuz uncertain. Markets are closed Friday for the Juneteenth holiday. All the shockwaves from Walsh will be digested within a single trading session on Thursday.

Tide Perspective

Walsh's abandonment of forward guidance has one direct consequence in the markets: Wall Street has lost the anchor it could rely on. For the past decade, the Fed provided a roadmap, guidance, and dot plots, and investors priced assets along these clues. By dismantling this entire framework, Walsh has permanently raised the uncertainty premium by one notch.

The semiconductor sector's strength against the trend shows that the long-term AI computing power logic has not been overturned. However, Meta leading the decline and SpaceX's first drop indicate that the valuation reset for interest-rate-sensitive, high-valuation tech stocks under the new framework where "the possibility of hikes exceeds cuts" has just begun.

Hope for bulls lies in two places: if the US-Iran deal lands smoothly on the 19th, the easing of the energy risk premium could offer a respite; the semiconductor sector's resilience on this day already suggests that as long as the AI capital expenditure story holds, the equipment chain will have support.

However, if the market chooses to continue digesting the hawkish shock upon Thursday's open rather than waiting for geopolitical benefits, this downtrend is not yet over. Walsh's debut is over. The next question is: when he speaks next, will it be before a rate hike, or after.

Related Questions

QWhat was the main reason for the broad market sell-off on June 18th as described in the article?

AThe main reasons were the Federal Reserve's hawkish dot plot, which showed half the officials forecasting a rate hike within the year, and the new Chair Walsh's announcement during the press conference to abandon forward guidance. This eliminated a key anchor for market expectations, leading to a reassessment of high-valuation assets and a broad sell-off.

QWhich was the only major sector or index to gain on that day, and what was the cited reason for its resilience?

AThe Philadelphia Semiconductor Index (SOX) was the only major sector to gain, closing up 1.38%. The article states that the long-term logic of AI computing demand remained valid despite the interest rate shock. Funds flowed out of interest-rate-sensitive software and internet stocks and found buyers in equipment and infrastructure stocks like Applied Materials, Lam Research, and Arm Holdings.

QWhat significant actions did new Fed Chair Walsh take during the June FOMC meeting and press conference, according to the article?

AChair Walsh announced the abandonment of the Fed's forward guidance during the press conference, stating 'I can't tell you what the next step will be.' Additionally, the policy statement was drastically shortened, removing all specific rate guidance and leaving only a commitment to price stability. The article also notes he reportedly did not submit his own dot plot, suggesting this might be the last dot plot publication.

QHow did key assets like the US Dollar, Gold, and Treasury yields react to the Fed's announcements?

AThe US Dollar jumped 0.86% to a two-month high. Gold fell 1.64%, erasing its weekly gains. Treasury yields spiked, with the 2-year yield rising 13 basis points to 4.18% and the 10-year yield increasing about 7 basis points to 4.49%, as traders priced in a high probability of a rate hike by September.

QAccording to the article's '潮向视角' (Trend Perspective), what are the two potential hopes for market bulls mentioned, and what is the key remaining uncertainty?

AThe two hopes for bulls are: 1) The potential for a U.S.-Iran deal to reduce energy price premiums if finalized, and 2) The continued resilience of the semiconductor sector, suggesting the AI capital expenditure story still provides a foundation. The key remaining uncertainty is when Chair Walsh will speak next—whether it will be before or after an actual rate hike action, as the lack of forward guidance has permanently raised market uncertainty.

NVIDIA CPU Advances, China's RISC-V Responds: Semiconductor Deep Dive - Part Four

NVIDIA is set to launch its new Vera AI data center CPU in China as early as August, with high pricing. While this move offers a new option, it highlights China's continued dependence on foreign-controlled Arm architecture. In response, the Chinese semiconductor industry is increasingly turning to RISC-V as a strategic alternative for achieving high-performance computing autonomy. The article explores the concept of the "impossible triangle" in CPU development—balancing prosperity, control, and autonomy—and posits that RISC-V's open-source, modular nature offers a unique path to achieving all three. While RISC-V is already dominant in embedded systems, the focus is now shifting to data centers and AI workloads. China has become a global hotspot for RISC-V development, driven by AI-driven compute demand, supply chain concerns from export controls, cost benefits of open-source, and strong policy support. Multiple Chinese companies have reportedly crossed the key performance threshold of 15 SPECint per GHz, a benchmark for entering the high-performance CPU club. Progress extends beyond single-core benchmarks. Companies are developing complete computing subsystems, including commercial-grade coherent network-on-chip (NoC) technology and server processors with up to 40 cores that strictly adhere to the RVA23 standard to ensure software compatibility. Real-world applications are emerging in areas like video transcoding and edge AI. However, significant challenges remain. The RISC-V ecosystem faces fragmentation, immature toolchains and verification processes, and gaps in single-core performance and energy efficiency compared to mature x86 and Arm architectures. The formidable software moat, epitomized by NVIDIA's CUDA, is a long-term hurdle. In conclusion, while RISC-V cannot immediately replace offerings like NVIDIA's Vera, it represents a viable long-term path for China to develop a self-sufficient, high-performance CPU ecosystem. The journey is acknowledged to be long and arduous, requiring sustained effort to overcome technical and ecosystem challenges.

My Coding Betting Dashboard is Profiting, but Polymarket is Truly Not a Good Place for 'Arbitrage'

The author built a custom monitoring dashboard for Polymarket, a prediction market platform, and tested it with $1,600, achieving over 30% returns. However, the core argument is that Polymarket is not a good venue for traditional arbitrage. The dashboard has two main sections: a "Portfolio Dashboard" for tracking active positions with key metrics like total capital, P&L, and a risk-control module using a tier system (T1, T2, T3), and an "Opportunity Watchlist" for monitoring markets. The article details a critical structural trap in binary markets: a bet with a high perceived probability of success still carries a 100% loss risk if wrong. The author's T1/T2/T3 system is designed to manage this by limiting position sizes based on conviction and time horizon, emphasizing that high confidence should not equal high concentration. A key insight is the danger of "pseudo-diversification"—betting on different markets driven by the same underlying variable. The author concludes that Polymarket offers few true low-risk, arbitrage opportunities. It is instead a high-risk environment where wins can create a false sense of mastery, leading to large losses. The platform is better viewed as a training ground for honing judgment through disciplined, framework-driven betting rather than a reliable income source. The tools help transform intuition into structured, rule-based decisions to mitigate the risk of catastrophic errors.

WeChat AI Card Hands-On Guide: Has the AI Shopping Era Arrived?

**"WeChat AI Card" Practical Test Guide: Has the Era of AI Shopping Arrived?** WeChat has officially launched the "AI Exclusive Card," a feature integrated into its Workbuddy AI assistant. This card is designed to handle payments for AI-initiated purchases. Our hands-on test reveals it's not yet a tool for fully autonomous AI shopping, but rather a controlled payment layer for AI agents. The AI Card functions as an isolated sub-wallet within WeChat Pay. Users must bind the card and transfer funds into it from their main wallet. Crucially, every transaction requires explicit user confirmation via smartphone scan; AI cannot spend autonomously. Currently accessible through the Workbuddy agent, the card targets specific digital consumption scenarios: purchasing paid content (reports, data), calling paid APIs/tools, and subscribing to services. Its design prioritizes security and control by separating funds and mandating approval for each payment. We tested a real-world scenario: ordering bubble tea via Workbuddy using a "Meituan Life Assistant" skill. The process encountered multiple hurdles: high "skill" usage costs (exceeding daily free credits), and most importantly, while a payment was successfully initiated, the AI purchased an incorrect product (a mismatched group-buy coupon instead of the desired drink). This highlights the current limitation: the **AI Card only solves the payment step**. The broader challenge lies in the **AI agent's execution chain**—accurately understanding intent, navigating third-party platforms, selecting the right product, and ensuring proper fulfillment. The payment succeeded, but the purchase failed to meet the user's need. In conclusion, the WeChat AI Exclusive Card is a cautious, early-step experiment in AI commerce. It provides a secure, user-controlled payment method for agent interactions but is not yet capable of reliable, end-to-end complex purchases. For now, it's best used for low-value, low-risk digital services with careful user verification at each step. The vision of AI handling complete shopping tasks remains a work in progress.
