Big Tech’s Ultra-Long Bond Issuance: Scaling New Heights Amid Growing Market Strains

Leading hyperscalers—Amazon, Google, Microsoft, and Meta—remain at the forefront of a historic wave of ultra-long and century bond issuance designed to lock in funding for multi-decade AI infrastructure investments. Amazon, in particular, has emerged as the dominant issuer, with:

• Over $165 billion in ultra-long bonds issued to date, primarily to finance its $200 billion AI infrastructure initiative focused on data centers and semiconductor fabrication capabilities.
• Google, Microsoft, and Meta collectively have contributed tens of billions more, pushing the cumulative issuance beyond $400 billion over the past two years.

These bonds, frequently maturing in 50 to 100 years, serve as strategic hedges against refinancing and interest rate risks in a persistently “higher-for-longer” Federal Reserve policy environment. However, this record issuance has further stretched dealer balance sheets, exacerbating liquidity constraints in the already less liquid ultra-long corporate bond segment.

IMF and Fed Signals Reinforce Prolonged Higher-for-Longer Interest Rate Environment

The International Monetary Fund’s latest warnings have sharpened market focus on the extended duration and refinancing risks associated with ultra-long debt:

• The IMF’s updated inflation outlook projects that U.S. inflation will not return to the Fed’s 2% target until 2027, delaying expectations of monetary easing and reinforcing a prolonged tightening cycle.
• This outlook has amplified concerns over duration risk in century bonds, which are highly sensitive to interest rate fluctuations and refinancing cost spikes.
• The 10-year, 10-year forward U.S. Treasury yield’s refinancing premium has surged to 5.62%, a 53.5 basis point increase, signaling elevated long-term funding costs.
• Investors and issuers are recalibrating risk models, increasingly factoring in the cost and volatility implications of an extended “higher-for-longer” cycle.

These dynamics create a challenging funding environment for Big Tech and other large corporate borrowers, raising the stakes for prudent risk management.

Escalating Sovereign Fiscal Pressures Compound Credit Market Vulnerabilities

Fiscal developments in the U.S. and globally have intensified pressures on credit markets, intersecting critically with Big Tech’s financing environment:

• The U.S. Supreme Court’s recent invalidation of key import tariffs has eliminated an estimated $175 billion in annual federal revenue, worsening budget deficits amid expansive spending plans.
• The IMF has issued renewed calls for urgent fiscal consolidation in Washington, warning that persistent deficits—projected to remain between 7% and 8% of GDP—threaten economic stability, especially given proposed defense budgets approaching $1.5 trillion.
• Global sovereign debt has surged to an unprecedented $348 trillion, driven by borrowing to manage geopolitical tensions and fiscal shocks.
• Central banks are actively diversifying reserves away from U.S. Treasuries:
  • The European Central Bank (ECB) has sold significant dollar assets, reducing the dollar’s share in its portfolio.
  • India has cut U.S. Treasury holdings by 18% over the past year, reflecting a broader trend of reserve portfolio recalibration.
• These shifts add upward pressure on funding premia for long-term corporate debt, including Big Tech’s ultra-long bonds.

Together, these fiscal and geopolitical factors elevate refinancing risks and credit spread volatility, complicating cost projections for AI-driven capex financing.

Market Structure Pressures: Dealer Constraints and Regulatory Mandates Challenge Liquidity

The massive scale of ultra-long issuance is placing unprecedented strain on market infrastructure and dealer capacity:

• Goldman Sachs projects $2.1 trillion in U.S. high-grade corporate debt issuance in 2026, with an additional €850 billion in European issuance, against a backdrop of a colossal $9 trillion Treasury rollover in 2026–2027.
• The SEC’s phased central clearing mandate for Treasury cash and repo markets, set for completion by mid-2027, aims to increase transparency but imposes higher operational and capital costs on dealers.
• Dealers confront compressed balance sheets and higher funding costs amid the Fed’s elevated rate regime, fostering a paradox described by economist Raghuram Rajan as “liquidity everywhere, but none to use.”
• This environment is fueling market fragmentation, impaired price discovery, and higher execution costs, particularly acute in the ultra-long bond space, which traditionally suffers from lower liquidity.

Without enhanced dealer capacity and regulatory adaptation, these market structure strains risk undermining efficient credit market functioning.

Central Banks’ Liquidity Interventions Reflect Divergent Approaches Amid Tightening Conditions

Central banks have adopted nuanced and, at times, divergent liquidity policies to balance inflation control with market stability:

• The Federal Reserve has episodically expanded its balance sheet since December 2025 to alleviate dealer funding stress amid the Treasury rollover, while maintaining a firm “higher-for-longer” guidance as of February 2026.
• The ECB and Sweden’s Riksbank have introduced targeted liquidity facilities supporting banks and dealers facing funding pressures.
• Conversely, the Reserve Bank of India (RBI) signaled a wind-down of its liquidity support after March 2026, potentially tightening global liquidity conditions and complicating cross-border funding.
• These differing central bank stances highlight the complexity of sustaining credit market liquidity amid record issuance and monetary policy tightening.

The interplay of these measures will be critical in influencing credit market resilience over the near term.

Investor Sentiment and Regulatory Scrutiny Intensify Around AI-Financed Ultra-Long Debt

Investor caution has increased markedly as opaque financing structures and liquidity constraints come under the spotlight:

• Surveys by Bank of America reveal “unprecedented Chief Investment Officer fatigue”, driven by worries over increasing leverage, expanding private credit channels, and thin secondary market liquidity.
• Influential investors, including Ray Dalio, have warned of a potential “AI spending bubble,” highlighting systemic risks from unchecked leverage and limited transparency.
• Secondary market liquidity challenges—exacerbated by dealer balance sheet constraints and regulatory clearing mandates—have impaired price discovery and heightened volatility.
• In response, investors are demanding:
  • Stronger covenant protections
  • Enhanced disclosure standards
  • Comprehensive due diligence frameworks
• Regulators are intensifying oversight of private credit vehicles supporting AI capex, pushing for greater transparency, investor protections, and standardized disclosures.

These developments mark a critical inflection point where transparency and risk mitigation become prerequisites for sustaining investor confidence in ultra-long corporate bonds.

Regulatory and Global Central Bank Coordination Seeks to Address Emerging Market Realities

The structural transformation driven by AI-related ultra-long financing has prompted increasing coordination among regulators and central banks:

• The Fed’s prolonged “higher-for-longer” stance underscores concerns about refinancing vulnerabilities and the opaque nature of private credit funding.
• The ECB and Riksbank’s liquidity initiatives aim to buttress banking and dealer resilience amid funding strains.
• Japan’s volatile sovereign bond market adds cross-border liquidity challenges, reverberating through global dealer balance sheets.
• Academic research points to a “silent monetary regime shift” as AI-driven ultra-long capex influences neutral interest rates and complicates monetary policy transmission.
• International regulatory bodies advocate for enhanced global coordination to develop frameworks addressing transparency, risk mitigation, and market stability amid growing ultra-long issuance.

Effective policy alignment will be vital to managing systemic risks posed by this evolving financing paradigm.

Forward Outlook: Navigating the Intersection of AI Innovation and Credit Market Complexity

The trillion-dollar AI capex wave, underpinned by record ultra-long bond issuance, presents both transformative opportunities and multifaceted risks:

• Ongoing monitoring of sovereign fiscal trajectories, tariff policy impacts, and global reserve diversification trends is critical to anticipate shifts in refinancing costs and credit risk premia.
• Developing tailored credit and liquidity risk frameworks suited to ultra-long maturities will be essential to manage duration and refinancing risks under a protracted tightening cycle.
• Strengthening disclosure requirements and covenant protections will underpin investor confidence and mitigate liquidity and credit risks.
• Enhancing international regulatory coordination, leveraging central bank liquidity initiatives, and navigating SEC clearing mandates are necessary to support dealer capacity and market functioning.
• Tracking investor sentiment and secondary market liquidity will provide vital early indicators of stress or shifts in risk appetite.
