American Finance Has Left Europe In the Dust. The Tables Aren’t Turning.

After a decade and a half of seeing the U.S. economy pull ahead thanks to its outsize technology sector, European politicians are desperate to fight back in emerging industries such as green energy. One challenge they face is that America also keeps pulling ahead in the business of financing the investments required.

On Thursday, Luxembourg for Finance—a public-private partnership that seeks to promote the financial industry in the low-tax city state—published a report detailing the different ways in which European banks and asset managers might regain an edge relative to U.S. and Asian peers.

This is part of an effort by officials across the European Union to give firms a break. “Old economy” industries such as car manufacturing face rising competition from China and higher energy costs since Russia invaded Ukraine. The U.S. Inflation Reduction Act also has drawn investment across the Atlantic. Last year, the European Commission tasked former Italian prime ministers Mario Draghi and Enrico Letta with drafting a report on European competitiveness.

Luxembourg for Finance Chief Executive Nicolas Mackel echoes a common refrain: “Europe can take the lead in financial services when we eliminate fragmentation.” His report points out that the return on equity of European banks has bounced back in recent years. But it also showcases the gulf that has opened up relative to U.S. financial firms.

European lenders’ return on equity is now around 8%, compared with 12% across the Atlantic and 10% in Asia, in part as a result of stricter regulations following the 2008 banking crisis. Most European banks trade below book value on the stock market, having returned a negative 14% to investors since the April 2009 trough. Large American banks trade above book value and have gained 113%.

In services particularly exposed to international competition, American banks dominate in Europe too: In 2023, they took the top five positions for mergers and acquisitions deals, Dealogic data shows, with France’s BNP Paribas coming in sixth, and the top six spots for issuing equity.

And this isn’t just about banks. In 2007, top European and U.S. asset managers roughly split the global market between them. By 2022, European fund managers had just 22% of total assets under supervision, with only France’s Amundi playing in the big leagues. This reflects their failure to jump on the train of low-fee passive investment as effectively as U.S. giants such as Vanguard and BlackRock. Ironically, the latter’s dominance in exchange-traded funds resulted from its acquisition of iShares from Britain’s Barclays in 2009.

European officials are taking some useful steps. They admitted in 2022 that a directive aimed at harmonising securities markets, known as Mifid 2, has done more harm than good, and have agreed to amend it. New EU-wide savings products give pensioners greater choice, and might help address the lack of sophistication that characterises European individual investors relative to Americans used to managing 401(k)s. Stringent constraints on what asset managers can offer are being relaxed, and the rules governing sustainable finance—where Europe has an edge—are being clarified.

Meanwhile, the fallout from last year’s Silicon Valley Bank debacle will bring U.S. regulation closer to Europe’s.

Such rule changes might narrow the gap, as investors have recognised: The stock-market discount at which European lenders trade compared with American ones has shrunk over the past three years. But it is hard to see the tables fundamentally turning. In the digital era, economies of scale are even more powerful. The European Union comprises many countries with different languages, whose firms and investors have local financial relationships and strong home biases. The obstacles to eliminating fragmentation are huge.

If Europe can’t compete with America’s private financial muscle, it is doubly problematic that its efforts to mobilize industrial investment through the public sector have been meek compared with the U.S. Inflation Reduction Act. Promoting more sustainability-minded funds isn’t an adequate fix.

A sharp technology sell-off has exposed a new anxiety on global markets: whether the enormous borrowing behind the artificial-intelligence infrastructure boom can generate sufficient returns as interest rates rise and Chinese competition intensifies.

The artificial-intelligence investment boom has powered technology shares, semiconductor manufacturers and data-centre operators to extraordinary heights. Last week, investors were given a reminder that much of this expansion is being built with borrowed money.

The technology-heavy Nasdaq Composite fell 4.5 per cent over the week ended October 16, its weakest performance since late June. Semiconductor shares suffered an even deeper correction, with the Philadelphia Semiconductor Index losing about 11.4 per cent.

The selling spread quickly through global markets. Micron Technology fell 14.6 per cent over the week, while South Korea’s Samsung Electronics and SK Hynix dropped approximately 18 per cent and 24 per cent respectively.

This was more than a routine bout of profit-taking. Investors were reassessing three interconnected risks: higher interest rates, the rapidly expanding debt burden attached to AI infrastructure and the prospect of stronger competition from Chinese memory-chip manufacturers.

The debt behind the AI build-out

Artificial intelligence requires a physical infrastructure network of enormous scale. Data centres must be built, advanced processors purchased, power supplies secured and cooling systems installed before customers begin generating meaningful revenue from them.

Technology companies are increasingly supplementing their own cash with corporate bonds, syndicated loans, equipment leases, private credit and project-level financing.

JPMorgan describes the emerging funding model as a combination of conventional corporate borrowing and project finance tied to individual data-centre assets. In Australia, the Reserve Bank estimates that syndicated loans accounted for approximately three-quarters of data-centre financing during 2025 and 2026 to date.

The numbers are becoming large enough to affect broader credit markets. The Federal Reserve Bank of Dallas has cited Wall Street estimates suggesting AI-related investment-grade bond issuance could approach US$300 billion in 2026 alone.

That borrowing is not automatically problematic. Debt can be an efficient way to finance long-lived infrastructure when future revenue is sufficiently predictable. The concern is that AI technology, customer demand and computing economics are changing much faster than the repayment schedules attached to the assets.

A data centre financed today may carry debt for years. Investors must therefore make assumptions about future utilisation rates, electricity prices, chip performance, customer concentration and the amount businesses will ultimately pay for AI computing.

When interest rates rise, those assumptions become less forgiving.

Inflation changes the calculation

September’s US inflation data intensified the pressure. Consumer prices increased 3.7 per cent over the year, ahead of market expectations and up from 3.4 per cent in August.

The hotter reading reduced confidence that interest rates would fall quickly and pushed bond yields higher. That matters particularly for companies whose valuations depend on profits expected well into the future, as well as highly leveraged infrastructure operators that may need to refinance.

CoreWeave has emerged as a closely watched test case. The specialist cloud-computing company has accumulated substantial debt and lease obligations to build AI capacity, while relying on a concentrated group of large technology customers.

Its shares fell sharply during the sell-off, while the cost of insuring its debt against default climbed. CoreWeave has argued that its contracted backlog more than covers its obligations and that financial markets do not always understand its business model. Nevertheless, its securities have become a proxy for investor confidence in debt-funded AI infrastructure.

Oracle, another major investor in AI computing capacity, fell 8.8 per cent in Friday trading, while CoreWeave dropped 15.5 per cent.

The question is shifting from how much AI infrastructure can be built to how profitably it can be operated.

China adds another source of pressure

Interest rates were not the only catalyst. Reports of advances by Chinese memory-chip producer ChangXin Memory Technologies raised concerns that lower-cost Chinese products could increase competition across the global semiconductor industry.

Memory chips are essential to AI systems, but the industry is historically cyclical. Periods of tight supply and high pricing can encourage rapid investment, eventually producing oversupply and falling margins.

The prospect of a well-funded Chinese competitor expanding its technological capabilities unsettled investors in Samsung, SK Hynix and Micron. It also demonstrated that AI-related demand does not insulate chipmakers from conventional competitive pressures.

That combination—slower rate cuts, more expensive financing and potentially cheaper supply—challenged the assumption that every company exposed to AI would enjoy continually expanding margins.

A reset rather than the end of the boom

The sell-off does not establish that the AI boom is ending. Demand for computing power remains strong, the largest technology companies continue to generate formidable cash flows and many infrastructure projects are backed by long-term customer contracts.

What has changed is the market’s willingness to overlook the price and financing structure of that growth.

The most resilient companies are likely to be those able to fund investment from operating cash flow, secure long-duration customers and demonstrate that new capacity will earn returns comfortably above its financing costs.

More speculative operators may face greater scrutiny, particularly where debt is expensive, customers are concentrated or expected revenue depends on demand that has not yet materialised.

For Australian investors, the lesson extends beyond US technology shares. Local data-centre operators, infrastructure funds, electricity suppliers and property groups are increasingly exposed to the same investment cycle.

Artificial intelligence may remain one of the defining growth themes of the decade. But last week’s correction showed that enthusiasm for the technology does not eliminate financial discipline.

The next stage of the AI boom will be judged not only by computing power, model performance or demand for chips, but by something more traditional: whether the assets being financed can generate enough cash to repay the money borrowed to build them.
