Global Markets Grapple with Japan's Policy U-Turn

For over two decades, Japan has been a cornerstone of global liquidity, with its institutions exporting trillions of dollars overseas in search of yield. That era appears to be drawing to a close. A potent combination of record-high domestic bond yields and an aggressive new fiscal agenda is creating powerful incentives for Japanese capital to return home, threatening to unwind a foundational pillar of the global financial system.

The "Takaichi Trade": A Mandate for Fiscal Expansion

A landslide election victory for Prime Minister Sanae Takaichi has provided a clear mandate for aggressive fiscal expansion. Her conservative coalition government secured 354 seats in the 465-seat lower house, with her Liberal Democratic Party alone winning 316 seats, its largest ever majority. This historic win was built on a pro-growth agenda, including a proposed two-year suspension of the 8% food sales tax, a move that would cost an estimated ¥5 trillion ($32 billion) annually.

Investor confidence following the result pushed Japan's Nikkei 225 up 3.9% to a new record high, briefly crossing the 57,000 level. The Japanese yen also strengthened, climbing 0.4% to just under 157 per dollar. This fiscal stimulus comes as Japan already shoulders the heaviest debt-to-GDP ratio in the developed world, at over 230%. Markets are now pricing in a potential flood of new Japanese Government Bond (JGB) issuance to fund these programmes, putting sustained upward pressure on yields.

JGB Yield Shock and the Unwinding Carry Trade

The impact on Japan's domestic bond market has been severe. Yields on 20, 30, and 40-year JGBs have soared to record highs, with the 40-year yield recently breaching 4.2% for the first time. This dramatic repricing follows the Bank of Japan's decision to raise its policy rate to 0.75%, a three-decade high, in response to inflation that has remained above its 2% target for four consecutive years.

This fundamentally alters the economics of the yen carry trade, a long-standing strategy where investors borrow cheaply in yen to invest in higher-yielding foreign assets. As the interest rate difference between Japan and other nations (like the US) narrows, the profitability of this trade collapses. A strengthening yen, driven by capital repatriation, would inflict further losses on those holding these positions, creating a self-reinforcing cycle of selling foreign assets to close out yen-funded trades.

The Multi-Trillion Dollar Repatriation Risk

Japanese institutions, from banks to pension funds, hold an estimated $5 trillion in overseas assets. Of this, approximately $1.2 trillion is held in US Treasuries, making Japan the largest foreign creditor to the United States. With domestic JGBs now offering competitive returns for the first time in a generation, the incentive to sell foreign holdings and bring capital home is immense.

A repatriation of even a fraction of these assets would exert significant selling pressure on US Treasuries and other global bonds, potentially driving borrowing costs higher globally. This mirrors the 2022 UK gilt market crisis, where a proposed fiscal expansion led to a sharp bond market sell-off. The US Treasury has already acknowledged the contagion risk, highlighting that the January rise in JGB yields "rippled through global fixed-income markets."

US Markets Hit Milestones Amid Shifting Tides

While risks build in Asia, US equity markets have been charting new territory, driven by a strong earnings season and a rotation into more traditional sectors. However, this optimism is tempered by upcoming economic data and subtle shifts from major foreign creditors.

Dow Jones Surpasses 50,000

The Dow Jones Industrial Average closed above the 50,000 mark for the first time in its 129-year history on Friday, 6 February 2026. The milestone was achieved on the back of a sharp rebound led by technology stocks, with the index surging more than 1,200 points, or 2.47%. The broader market also saw significant gains, with the S&P 500 rallying 1.97% and the Nasdaq Composite climbing 2.18%. However, despite the strong session, both the S&P 500 and Nasdaq still recorded losses for the week, highlighting underlying fragility.

This rally is underpinned by a very strong corporate earnings season. So far, 76% of S&P 500 companies have reported a positive earnings surprise, with a blended growth rate of 13%. The average revenue growth of 8.8% marks the fastest pace since the third quarter of 2022. The move was also spurred by a strong University of Michigan consumer sentiment report that eased inflation fears and signalled a broadening of the market rally beyond tech into industrial and financial shares. Despite the historic high, futures traded lower at the start of the week, indicating that sentiment remains cautious ahead of key data releases.

Economic Data on the Horizon

All eyes are now on a crucial week for economic data. The January jobs report is due on Wednesday, with economists expecting the addition of 70,000 nonfarm payrolls and the unemployment rate to hold steady at a low 4.4%. This will be followed by the Consumer Price Index (CPI) report on Friday. The market consensus is for headline inflation to cool to 2.5% year-over-year, down from 2.7% in December. Any deviation from these expectations could significantly influence the Federal Reserve's stance on interest rate cuts, impacting growth stocks and the broader market.

China Curtails US Treasury Holdings

Adding another layer of complexity to the global bond market, Chinese regulators are reportedly guiding the nation's commercial banks to reduce their holdings of US Treasuries. This guidance is framed as a measure to manage interest rate and concentration risk rather than a direct geopolitical move. The objective is to shield Chinese financial institutions from potential mark-to-market losses caused by sharp swings in US interest rates. While the immediate market impact has been modest, this "quiet quitting" by another major foreign buyer of US debt adds to the potential for sustained upward pressure on Treasury yields.

AI's Growing Influence Sparks Market Volatility

The artificial intelligence narrative is rapidly maturing from a story of boundless growth to one of immense cost and competitive disruption. Recent announcements have exposed the fault lines in the sector, leading to significant market re-pricing.

Big Tech's $660 Billion Spending Spree Triggers Wipeout

Leading technology firms have asked investors to absorb their most aggressive spending cycle in history. Amazon, Alphabet, Microsoft, and Meta plan to spend a combined $660 billion on AI infrastructure in 2026, a 60% increase from 2025 and nearly triple the levels of 2024. The sheer scale of this capital expenditure triggered a sharp investor backlash, wiping out over $1 trillion in collective market value from the tech giants. The sell-off reflects growing fears of an AI bubble and questions whether future earnings can justify such enormous outlays in the near term.

In a notable strategic contrast, Apple has avoided this capital-intensive race. Instead of building its own foundational models, the company has cut its capital expenditure and reportedly struck a deal worth around $1 billion annually to integrate Google's Gemini AI into its products. This shifts the infrastructure cost off its balance sheet, a move that investors rewarded while punishing the heavy spenders.

Anthropic's Claude Challenges Financial Data Incumbents

AI's disruptive power was made clear when AI firm Anthropic released its Claude Opus 4.6 model, specifically optimised for financial analysis. The new model topped industry benchmarks for common analyst tasks, putting it in direct competition with the core products of data providers like S&P Global and FactSet. The market reaction was immediate, with shares in both incumbents falling sharply as investors priced in the risk of their legacy platforms being rendered obsolete by more capable and efficient AI tools.

Samsung Gains Edge in AI Chip Race

Samsung appears to have secured a first-mover advantage in the next generation of high-bandwidth memory (HBM) chips critical for AI accelerators. The company is reportedly beginning mass production of its HBM4 chips this month, with initial shipments planned for Nvidia. This development positions Samsung ahead of competitors SK Hynix and Micron, whose shares dipped on the news. However, with demand for HBM chips still vastly outstripping supply and major customers like Nvidia committed to a three-supplier strategy, Samsung's early lead is expected to ease a global supply bottleneck rather than trigger a price war.

The Shift to Embodied AI

Beyond data centres, AI is beginning to take physical form, with major industrial and technology players investing heavily in robotics. Tesla has announced it is ending production of its Model S and X vehicles to convert the factory capacity into a production line for its Optimus humanoid robot. This follows similar moves by Chinese EV rival XPeng, which is also ramping up its humanoid robot development. This pivot towards 'embodied AI' signals the next frontier of automation, which will further accelerate demand for AI chips, connectivity, and power generation.

Private Credit Markets Face New AI-Driven Risks

The AI revolution is creating new uncertainties in the $3 trillion private credit market. A significant portion of private loans has been extended to software companies, many of which are now vulnerable to disruption from AI-driven tools. Last week saw shares of asset managers with large private credit exposure fall as investors grew concerned that AI could upend borrowers' business models, pressure cash flows, and ultimately increase default rates in this opaque corner of the financial markets.

Corporate and Regulatory Headwinds

Several companies faced significant challenges due to regulatory actions, operational missteps, and shifting market dynamics.

Stellantis's Costly EV Miscalculation Deepens

Automaker Stellantis is paying a high price for overestimating consumer appetite for electric vehicles. The company announced a staggering $26 billion charge tied to its EV strategy reset. CEO Antonio Filosa admitted the company had misread the pace of adoption and consumer needs, leading to a significant writedown that dwarfs recent EV-related charges at Ford ($19.5B) and General Motors ($7.6B).

The strategic error is reflected in its performance, with global sales falling 12.3% between 2021 and 2024 and US sales plummeting 27%. In response, Stellantis has suspended its 2026 dividend and issued a hybrid bond to shore up its balance sheet. The company is now attempting a reset, pledging $13 billion in US investments to claw back market share, which includes reintroducing V8 engines to certain models.

Boeing Turnaround Gains Momentum with Major India Deal

After a turbulent seven-year period marked by safety crises and heavy losses, Boeing appears to be gaining altitude. The planemaker is set to be a major beneficiary of a new trade framework with India, which could lead to aircraft orders worth up to $80 billion. This follows recent large orders from Qatar and British Airways. Financially, the company posted an $8.2 billion Q4 profit, its first quarterly profit in three years, signalling that the operational bleeding has stopped. The key test now is execution, as the company must secure regulatory approval for delayed aircraft variants and navigate potential labour strikes.

Hims & Hers Faces Lawsuit Over Weight-Loss Drug

Telehealth company Hims & Hers Health (HIMS) abruptly withdrew its new, cheaper compounded weight-loss pill just two days after its launch, and is now facing legal action from pharmaceutical giant Novo Nordisk. Novo Nordisk has filed a lawsuit asking the court to stop Hims from selling compounded versions of its drugs, accusing the company of "deceiving patients and putting their health at risk."

The decision to halt sales followed a stern warning from the US Food and Drug Administration (FDA) and a referral to the Department of Justice (DOJ) for investigation. The swift enforcement action underscores a regulatory crackdown on unauthorised GLP-1 knockoffs. Shares of Hims & Hers fell over 20% in pre-market trading on the news, highlighting the significant legal and compliance risks for companies operating in this market.

Bithumb's £34 Billion "Ghost Bitcoin" Incident Triggers Oversight

A significant operational error at Bithumb, South Korea's second-largest crypto exchange, exposed structural risks in the digital asset market. An employee mistakenly credited users with 620,000 Bitcoin (worth approximately £34 billion) instead of a small promotional bonus. This "ghost Bitcoin," which existed only on the exchange's internal ledger, led to a localised flash crash as some users managed to sell the non-existent assets.

In response, South Korea's Financial Supervisory Service announced it will step up crypto market supervision and impose tougher penalties for IT failures. The regulator is launching targeted probes into price manipulation and misinformation as it prepares for the forthcoming Digital Asset Basic Act.

Meta Faces Dual Legal Battles Over User Safety

Meta is bracing for a challenging week as opening arguments begin in two separate trials that could have significant repercussions for the social media industry. One trial, in New Mexico, accuses the company of failing to protect children from online predators on its platforms. A second trial in Los Angeles alleges that Meta, along with YouTube, failed to warn young users about the potential for their apps to harm mental health. These cases intensify the legal and regulatory pressure on major technology firms regarding their responsibilities for user safety and content moderation.

Sector Pressure on Health Insurers

US health insurance companies with significant exposure to Medicaid faced a sharp sell-off. Molina Healthcare (MOH) shares plunged after reporting earnings far below expectations, citing that rising healthcare costs are outpacing the reimbursement rates paid by the government programme. Similarly, competitor Centene projected its 2026 revenue would fall short of estimates, though it signalled that medical costs were beginning to stabilise.
