Oil and U.S. Treasury Yield Declines Lift Nasdaq Tech Shares; U.S.-China Summit, the AI “Red Phone,” and the Westinghouse IPO

The key market driver was not simply that technology stocks rose.

A pullback in crude oil and lower U.S. Treasury yields supported a relief rally in U.S. equities, while expectations for additional Federal Reserve tightening remained elevated.

At the U.S.-China summit, discussions extended beyond a tariff truce renewal to include an “AI red phone” to prevent AI-related incidents from escalating into military or security conflicts.

The Westinghouse IPO, tied to AI data center power demand, is also a significant issue with implications for nuclear stocks, Korea Electric Power, Doosan Enerbility, KHNP, and Hyundai Engineering & Construction.

This report reviews U.S. equities, crude oil, U.S. Treasury yields, Fed tightening risk, and AI investment trends.

1. New York Market Tone: Lower Oil and Long-Term Yields Drive a Relief Rally in Tech

U.S. markets opened the week with improving risk appetite.

S&P 500 futures rose about 0.65%.

Nasdaq 100 futures gained more than 1%, signaling a strong rebound in technology shares.

Dow futures rose about 0.8%, while Russell 2000 futures advanced around 0.7%.

European futures were also firm.

Euro Stoxx 50 futures rose in the mid-1% range, and DAX futures gained more than 1%, reflecting broad global buying.

• Nasdaq 100 futures: up more than 1%.
• S&P 500 futures: up in the 0.6% range.
• Dow futures: up in the 0.8% range.
• Russell 2000 futures: up in the 0.7% range.
• Major European futures: up more than 1% across the board.

After the open, Nasdaq gains widened further.

The Nasdaq rose about 1.49%, led by semiconductors and AI infrastructure names.

The S&P 500 gained about 0.72%, the Dow about 0.2%, and the Russell 2000 about 0.45%.

2. VIX Moves Lower: Market Stress Eases, But Risks Remain

The VIX declined to around 17.75, down more than 1% from the previous session.

The decline suggests investors were less concerned than they were last week.

However, it would be premature to interpret this as a full risk reset.

Expectations for further Fed tightening remain elevated.

Today’s rally appears to be a relief move driven by lower oil and Treasury yields rather than a structural breakout.

3. Crude Oil Falls Sharply: WTI in the Low $90s, Brent Near $100

Oil was the main catalyst for the broader market rebound.

WTI fell about 3.6% to the low $90s per barrel.

Brent declined about 2.9% to around $100 per barrel.

The drop in oil eased inflation concerns and helped stabilize long-term Treasury yields.

The decline was driven by two main factors.

• First, geopolitical tensions in the Middle East remain elevated, but actual crude supply has been holding up better than expected.
• Second, President Trump said he would be open to meeting Iran’s president during the UN General Assembly period, which raised hopes for reduced diplomatic tension.

According to U.S. Central Command, crude flows through the Strait of Hormuz have reached the highest level in six months.

That reduced concerns over supply disruption.

Gasoline, heating oil, and gasoil also declined.

Gasoline prices fell by nearly 4%, which is particularly relevant for consumer inflation and transportation costs.

For inflation, broad fuel price declines matter more than crude alone.

4. U.S. Treasury Yields: Long-End Stabilizes, Short-End Barely Moves

In the bond market, longer-duration Treasuries rallied, pushing yields lower.

The 10-year Treasury yield briefly moved above 5% before easing back into the high-4% range.

The 30-year Treasury also stabilized.

Lower long-term yields reduced valuation pressure on growth and technology stocks.

That directly supported semiconductors and AI infrastructure names.

Short-term yields, however, barely changed.

This indicates that the market still sees a meaningful probability of further Fed hikes.

In other words, long-end yields eased on lower oil, but monetary policy risk remains intact.

5. Gold and Copper Signal a Shift Toward Growth Over Defense

Gold weakened.

That reflects lower demand for defensive assets.

Copper rose about 1.9%.

Copper is highly sensitive to the industrial cycle.

A weaker gold price and stronger copper price suggest that the market is shifting toward growth and cyclicals.

Iron ore also edged higher.

This mix is supportive for cyclical and industrial stocks in the near term.

6. FX Market: Dollar Firm, Yen Weak Around 157 Per Dollar

The dollar index rose modestly to around 99.99.

As the dollar strengthened, most major currencies weakened.

The yen was particularly weak.

USD/JPY rose from the high 156s to around 157.

Notably, the yen weakened despite the Bank of Japan raising its policy rate from 1.00% to 1.25%.

Normally, a rate hike would support the currency, but that was not the case here.

There are three reasons.

• First, the hike had already been largely priced in.
• Second, Governor Ueda did not clearly signal the timing of the next increase or the terminal rate.
• Third, U.S. rates also rose, leaving the U.S.-Japan rate differential largely intact.

As a result, carry trade incentives remain in place.

The structure of borrowing low-yield yen to buy higher-yield dollar assets is still intact.

In addition, Japanese markets were closed early in the week, which reduced liquidity and may increase FX volatility.

7. Japan Intervention Risk: Why Authorities Conduct Rate Checks

Japanese authorities reportedly conducted a rate check with banks.

A rate check is a procedure in which officials contact banks to confirm the prevailing bid and offer levels in USD/JPY.

Markets often treat this as a precursor to FX intervention.

In other words, it signals that the government may sell dollars and buy yen if weakness persists.

Japan has intervened in the FX market on a large scale before.

Because recent intervention was already close to record size, the market is not dismissing this signal.

Yen weakness can also affect the won.

Global investors often view the yen, yuan, and won as part of an Asia FX basket.

8. Semiconductor Shares Surge: AI Infrastructure and Data Centers Return to the Forefront

Semiconductor stocks were the strongest individual names.

After a weaker open, gains widened and drove Nasdaq outperformance.

• Nvidia: up about 0.8% intraday.
• AMD: up more than 8% intraday.
• Intel: up more than 9% intraday.
• Arm: up more than 12% intraday.
• Micron: up about 3%.
• Broadcom, Marvell, and Qualcomm also advanced.

Last week, AI spending concerns and a spike in Treasury yields weighed on semiconductors.

Today, lower oil and lower long-term yields reduced pressure on growth valuations.

That brought buyers back into semiconductors and AI infrastructure names.

Data center-related stocks also advanced.

Dell, Arista Networks, and SanDisk rose as servers, networking, and storage names rallied.

This indicates that AI data center investment remains one of the market’s dominant themes.

9. Big Tech: Semiconductors Strong, Software Mixed

Large-cap tech stocks mostly rose.

Meta strengthened through the session.

Tesla advanced, while Amazon and Alphabet also gained.

Microsoft posted a more limited gain.

Apple weakened early before turning slightly positive.

The key point is differentiation within technology.

Semiconductors, data centers, servers, and networking equipment tied directly to AI were strong.

Software names were more mixed.

The market continues to assign a higher premium to AI infrastructure suppliers than to AI application software.

10. Accenture and Anthropic Collaboration: AI Validation Becomes a Growth Market

Accenture rose after announcing a collaboration with Anthropic.

The two firms plan to validate and stress test Anthropic’s AI models.

This matters because the AI market is expanding from model development to safety, validation, and deployment consulting.

As companies adopt AI, they need to evaluate safety, regulatory exposure, and real-world error rates.

This creates additional opportunities for consulting firms, cloud providers, and cybersecurity companies.

11. Media Stocks Advance as Regulatory Uncertainty Eases Around Paramount and Warner Bros. Discovery

Media stocks also moved higher.

Warner Bros. Discovery and Paramount Skydance were both firm ahead of the open.

Reports that Paramount and California were close to an agreement supported sentiment.

The proposed arrangement reportedly includes a $1.5 billion investment in film and TV production in California and a commitment to keep local studios in place.

The prospect of lower regulatory uncertainty supported the shares.

12. Bitcoin Surges: Above $85,000, but Not Yet a Full Crypto Rebound

Bitcoin jumped nearly 5% and moved above $85,000.

That is the highest level since January.

It is also up about 7% over the past five days and nearly 35% over the past three months.

Bitcoin-linked equities such as Coinbase, Strategy, Circle, and Robinhood also gained.

The move was notable because several headwinds were in place.

The Clarity Act, which had been expected to support the digital asset sector, stalled in the Senate, reducing the likelihood of passage this year.

At the same time, Fed tightening expectations remained elevated.

Despite that, Bitcoin rose for three reasons.

• First, expectations remain for greater institutional participation by firms such as BlackRock.
• Second, Strategy added 950 Bitcoin for about $75.7 million.
• Third, some capital may be rotating from AI into digital assets.

Even after the rally, Bitcoin remains well below its prior peak.

Rather than signaling a full return to a crypto bull market, the move looks more like a rebound driven by improved risk appetite and institutional buying expectations.

13. Key U.S. Economic Calendar This Week: U.S.-China Summit and Fed Speeches

This week has fewer major inflation releases, but several political, diplomatic, and monetary-policy events may move markets.

• Monday: speeches by Chicago Fed President Goolsbee and New York Fed President Williams.
• Tuesday: ADP weekly labor data, Richmond manufacturing index, Fed speaker events, and a 2-year Treasury auction.
• Wednesday: Fed speakers, EIA oil inventory data, and a 5-year Treasury auction.
• Thursday, 9:00 a.m. KST: summit between President Trump and President Xi.
• Thursday: U.S. labor and housing data.
• Friday: durable goods orders and inflation expectations data.

Markets are watching for short-term inflation expectations around 4.6% and 5-year expectations around 3.4%.

If expectations rise again, the case for further Fed tightening could strengthen.

14. Earnings This Week: Costco as a Barometer for U.S. Consumption

This week’s earnings calendar is relatively light, but Costco is the key report.

On Tuesday, AutoZone, Thor Industries, and KB Home report.

On Wednesday, Cintas, General Mills, and Paychex report.

On Thursday before the open, Darden Restaurants and TD SYNNEX report.

On Thursday after the close, Costco reports.

Costco is a useful indicator of U.S. consumer demand.

The market expects EPS of about $6.53 and revenue of about $94.86 billion.

Investors will focus on same-store sales, customer traffic, average ticket size, and e-commerce growth.

Strong consumer demand would make it harder for inflation to moderate, which matters for the Fed.

15. Fed Commentary: Kashkari and Goolsbee Both Warn on Inflation

The Fed raised rates by 25 basis points last week.

The target range is now 3.75% to 4.00%.

Sixteen of the 18 FOMC participants expect at least one more hike this year.

Minneapolis Fed President Neel Kashkari said the inflation problem is not only about energy.

He pointed to persistently high core inflation, especially in services.

Kashkari said the U.S. economy is strong enough to absorb additional tightening.

Chicago Fed President Austan Goolsbee gave a similar warning.

His comments were more direct.

He said the path back to the 2% inflation target will not be painless.

He also noted that AI investment is boosting demand in the broader economy.

That suggests AI is not only lifting tech stocks, but also increasing demand for investment, labor, power, construction, and equipment.

16. Fed Funds Futures: Markets Price in a High Probability of Another Hike

According to CME Fed Funds futures, markets continue to price in additional Fed tightening.

The highest-probability path is a 25-basis-point hike in both October and December.

That scenario is priced at about 39.7%.

The second-most likely path is no change in October followed by one hike in December, with a probability of about 35%.

The probability of a hike in October and no change in December is about 13.4%.

The probability of no change in both months is only about 11.9%.

In short, markets are pricing in at least one additional hike by year-end with a probability of about 88%.

Although U.S. equities rose today, Fed tightening risk has not disappeared.

17. U.S.-China Summit Focus 1: Extending the Trade Truce

This week’s main event is the summit between President Trump and President Xi.

Xi is scheduled to visit the United States from the 23rd to the 25th, with the summit set for the 24th.

The first key issue is extending the U.S.-China trade truce.

The two countries previously imposed additional tariffs of more than 100% on each other, creating a near-breakdown in normal trade.

Subsequent talks in Geneva and Busan extended the truce by one year.

That truce expires on November 11.

The U.S. believes China has not fully delivered on rare earth supply commitments.

Washington also sees limited progress on purchases of U.S. agricultural goods and more than 200 Boeing aircraft.

As a result, whether the truce can be extended is an important variable for global equities.

18. U.S.-China Summit Focus 2: An AI Red Phone for the AI Era

A new issue has emerged ahead of the summit: AI security.

The U.S. has proposed an emergency communication channel for immediate notification if an AI-related incident occurs.

The New York Times described it as an AI-era version of the Cold War hotline, or an “AI red phone.”

Examples include large-scale cyberattacks using AI, biological weapons development, nuclear-system malfunction, or military system errors that could be misread as an attack.

The red phone is intended as a basic safeguard against escalation.

Secretary Bessent said that because the U.S. and China are the world’s two leading AI powers, it is important to avoid a situation in which neither side knows what the other is doing.

However, sensitive issues such as advanced AI chip export controls, semiconductor equipment restrictions, and limits on AI development speed were reportedly left outside this discussion.

19. Sam Altman’s Comment and the Practical Limits

OpenAI CEO Sam Altman said President Trump and President Xi would deserve a Nobel Peace Prize if they reached an international agreement to slow the pace of AI development.

That outcome appears unlikely.

China has been skeptical of any proposal to slow AI development.

For now, the realistic outcome may be limited to a communication channel for AI incidents rather than a broader development restraint agreement.

20. Westinghouse IPO: A Symbol of AI Power Demand and the Nuclear Revival

Westinghouse may file for an IPO as early as October.

The company is targeting a valuation above $50 billion.

Westinghouse filed for bankruptcy in 2017 after cost overruns in U.S. nuclear construction.

Brookfield Asset Management later acquired it for $4.6 billion and refocused the business on nuclear fuel, components, and maintenance services rather than large construction risk.

When Cameco acquired a stake in 2023, the company was valued at about $8.2 billion.

Now the target valuation is as high as $50 billion.

The re-rating reflects AI data center power demand and U.S. policy support for nuclear power.

The U.S. government is pursuing a plan that could involve up to 10 Westinghouse AP1000 reactors and more than $80 billion of investment.

AI investment is driving electricity demand sharply higher, and nuclear power is increasingly viewed as a stable supply solution.

21. Westinghouse and Korea: Links to KEPCO, Doosan Enerbility, and Hyundai Engineering & Construction

Korea is directly tied to the Westinghouse story.

The U.S. and Korea are discussing the possibility of Korean participation in Westinghouse equity.

Korea Electric Power is being considered as a potential buyer.

The issue is valuation.

If Westinghouse is valued at $50 billion, a 10% stake would cost about $5 billion, or roughly 7 trillion won.

KEPCO’s debt exceeds 210 trillion won, so the financial burden would be significant.

However, an equity stake could give Korea a board seat and access to U.S. nuclear projects.

That could also benefit Doosan Enerbility through equipment supply, Hyundai Engineering & Construction through construction work, and KHNP through operating participation.

In other words, this is not only an equity investment but also a question of whether Korean firms can enter the U.S. nuclear supply chain.

22. Asia Holiday Calendar: Closures in Japan, Korea, China, and Taiwan Could Raise Volatility

Several major Asian markets are closed this week for holidays.

Japan is closed from Monday through Wednesday.

Korea is closed on Thursday and Friday for the Chuseok holiday.

Mainland China and Taiwan are closed on Friday for the Mid-Autumn Festival.

Hong Kong remains open.

Holiday closures can reduce liquidity and increase volatility.

Japan, in particular, enters the holiday period after a rate hike and yen weakness, which could increase FX volatility further.

23. Energy and Healthcare Lag

Energy stocks weakened as crude oil fell sharply.

Major energy names declined by about 1% to 2%.

Financials and industrials were stronger.

Healthcare was mixed on a stock-specific basis.

Some large-cap healthcare names, including Eli Lilly and Johnson & Johnson, were weaker.

24. One-Sentence View of Today’s Market: A Relief Rally in AI Semiconductors Driven by Lower Rate Pressure

Today’s market was a relief rally in technology shares driven by lower oil and lower long-term yields.

Semiconductors and AI infrastructure names attracted strong buying.

However, the probability of further Fed tightening remains high.

Oil has eased, but Brent is still near $100 per barrel.

Accordingly, this move is better viewed as a reversal of last week’s shock rather than the start of a new bull market.

25. The Most Important Point That Is Often Missed

The most important development is that AI is now becoming not only a growth theme, but also an inflation variable and a geopolitical variable.

Many investors focus only on “AI semiconductors rallied” or “Nasdaq rose.”

But the key point in Goolsbee’s comments is that AI investment is driving demand across the U.S. economy.

Building AI data centers requires more spending on power, land, construction, equipment, semiconductors, cooling systems, and transmission networks.

That supports productivity expectations, but it also adds inflation pressure.

The discussion of an AI red phone at the U.S.-China summit shows that AI is increasingly treated as a military miscalculation and national security risk.

AI is no longer just a matter of big tech earnings; it is now tied to central banks, the White House, Beijing, energy policy, and the nuclear industry.

Investors should therefore look beyond revenue growth when evaluating AI names.

Power costs, regulatory risk, U.S.-China tech competition, rate sensitivity, and data center bottlenecks also matter.

The Westinghouse IPO fits the same framework.

Nuclear power is being revalued not simply as a clean-energy theme, but as core infrastructure for AI data center electricity demand.

The next bottleneck in AI may be power, not semiconductors.

26. Key Checkpoints for Investors This Week

• Whether WTI remains in the low $90s and Brent moves further below $100.
• Whether the 10-year Treasury yield stays below 5% and stabilizes.
• How forcefully Fed officials continue to signal additional tightening.
• Whether the U.S.-China summit produces concrete progress on the trade truce and AI incident hotline.
• Whether the yen reverses around 157 following possible intervention by Japanese authorities.
• Whether Costco signals any slowdown in U.S. consumer demand.
• Whether the semiconductor rally proves to be a short-term rebound or part of a broader AI infrastructure trend.
• Whether Bitcoin’s rise is supported by institutional buying or simply broader risk-on sentiment.
• Whether Westinghouse-related news extends to nuclear stocks and Korea’s nuclear value chain.

< Summary >

Lower crude oil prices and easing U.S. Treasury yields drove a strong rebound in the Nasdaq and semiconductor shares.

However, expectations for additional Fed tightening remain elevated, with markets still pricing in at least one more hike this year.

At the U.S.-China summit, the extension of the trade truce and an AI incident communication channel emerged as the key issues.

The yen weakened despite a Bank of Japan rate hike, raising the likelihood of FX intervention.

Bitcoin moved above $85,000 on institutional buying expectations and capital rotation.

The Westinghouse IPO links AI data center power demand to the nuclear revival theme.

This rally is best viewed as a relief move driven by lower oil and lower long-term yields rather than the start of a new bull market.
