The artificial intelligence boom, which has captivated global markets and driven extraordinary valuations across the technology sector, is encountering skepticism in an unexpected quarter: the debt markets. Companies at the forefront of the AI revolution, including household names such as Oracle, Nvidia and Apple, are facing sharply elevated costs to insure their bonds against default. This phenomenon reflects a fundamental anxiety rippling through sophisticated investors' calculations: despite pouring hundreds of billions into artificial intelligence infrastructure and development, when will these sprawling investments finally translate into tangible, sustainable profits?

The mounting pressure manifests most visibly in the credit default swap market, a relatively obscure but consequential corner of global finance where investors purchase protection against the possibility that borrowers will fail to repay their debts. This derivative instrument, which gained notoriety during the 2008 financial crisis when it amplified systemic risks, has suddenly become a focal point for measuring investor sentiment toward the technology sector's debt-financed expansion. The acceleration of trading activity in these instruments signals that major financial players are increasingly hedging their exposure to technology companies, effectively betting that the risks have grown more substantial.

Credit default swaps function as a form of financial insurance tailored for the bond market. When investors purchase bonds, they expect to receive regular interest payments and the return of their principal investment at maturity, but they simultaneously bear the risk that these payments may never arrive. A CDS creates a protective contract whereby a seller agrees, in exchange for a regular fee, to compensate the buyer if the bond issuer experiences a credit event such as bankruptcy or failure to meet payment obligations. The global market for single-name CDS, which cover the debt of individual issuers, represents approximately $9 trillion in notional value according to the International Swaps and Derivatives Association, though this remains a modest portion of the far larger universe of global bond markets exceeding $150 trillion.

The mechanics of CDS pricing reveal the intensity of current concerns about technology companies. These contracts are quoted in basis points, which represent hundredths of a percentage point. A CDS with a spread of 100 basis points costs precisely $1 annually per $100 of insured debt. Oracle, a leading cloud computing and artificial intelligence platform provider, currently trades at approximately 200 basis points, a rate that substantially exceeds peers and reflects acute investor wariness. Nvidia, the dominant semiconductor manufacturer whose chips power artificial intelligence systems, has experienced sharp recent increases, trading around 78 basis points. Meta Platforms sits near 93 basis points. By comparison, an index tracking investment-grade corporate debt more broadly trades near 53 basis points, highlighting how much more expensive protection has become for technology leaders.

The surge in CDS activity reflects a significant shift in risk perception among institutional investors and hedge funds that populate the derivatives market. During the second quarter of 2024, daily trading in CDS linked to technology companies reached nearly $650 million, representing a 20 percent quarterly increase and almost a sixfold jump from the equivalent period one year earlier. This expansion has been driven by newly participating companies including Meta, Nvidia and Alphabet, each entering the CDS market for the first time as their debt loads expanded to finance artificial intelligence initiatives. In aggregate, daily CDS trading across all issuers climbed to $16 billion in the second quarter, up from $13 billion in the prior year, though government debt remains the largest market with Saudi Arabia's CDS generating approximately $500 million in average daily notional trading.

Underlying this surge lies a specific and measurable concern: the extraordinary capital expenditures that artificial intelligence development demands may not generate returns proportionate to the investment. Technology giants have collectively borrowed tens of billions of dollars in recent years to finance artificial intelligence infrastructure, with companies expanding their debt offerings to fund facility construction, semiconductor purchases and research programmes. Even when these companies deliver robust earnings reports and maintain dominant market positions, certain investors remain unconvinced that they can eventually generate sufficient profits to justify their borrowing costs. The calculus becomes particularly acute when one considers that artificial intelligence infrastructure represents a largely experimental domain where competitive dynamics remain unsettled and regulatory frameworks continue evolving.

The structure of the CDS market itself amplifies the impact of this shifting sentiment. Unlike centralized stock exchanges where millions of transactions occur simultaneously, CDS trading occurs primarily in over-the-counter arrangements between investment banks, hedge funds and institutional investors. The market remains characterised by relatively thin trading volumes even for the world's largest companies, with average daily transaction counts sometimes numbering in the single digits. This illiquidity means that when investor anxiety accelerates and trading activity concentrates, relatively modest volumes can produce outsized price movements. A handful of large trades seeking protection can substantially widen CDS spreads, effectively raising the perceived cost of borrowing for the underlying companies and potentially triggering a self-reinforcing cycle where rising protection costs convince additional bondholders to sell their holdings.

This dynamic introduces a troubling feedback mechanism that authorities and market participants closely monitor. As the cost of CDS protection rises, bond investors increasingly conclude that holding the underlying debt has become unnecessarily risky relative to the insurance premium required. These investors then sell their bond holdings, which increases the supply of bonds in the secondary market and depresses their prices. Higher bond yields and lower prices represent functionally equivalent expressions of increased borrowing costs. Companies subsequently face more expensive refinancing conditions and potentially impaired access to debt markets altogether. This mechanism can transform investor anxiety into concrete financial constraint, potentially forcing companies to curtail investment plans or accelerate asset sales at disadvantageous valuations. The insurance market designed to protect bond investors can paradoxically accelerate credit deterioration.

For Malaysian investors and businesses operating in Southeast Asia, the implications warrant careful consideration. The region's technology sector and technology-dependent industries maintain substantial exposure to major American technology companies through supply chain relationships, partnership agreements and equity investments. Elevated borrowing costs for American technology giants could slow their capital expenditure programmes and potentially reduce demand for inputs from regional suppliers. Additionally, Malaysian financial institutions and fund managers that hold technology company bonds or have exposure to global financial system stability face tangible consequences if technology sector credit stress intensifies and spreads to the broader financial system. The artificial intelligence investment thesis that has driven global valuations higher could encounter more substantial skepticism if technology companies cannot demonstrate that their extraordinary expenditures are generating commensurate returns within reasonable timeframes.
