Pimco warns default cycle returning, urges bond pivot at $2.27 trillion

Pimco warned the credit-loss cycle has begun, predicting significantly higher defaults in leveraged loans and private direct lending as AI-related debt issuance runs at roughly $100 billion a quarter.

"After years of effortless returns, the default cycle is reasserting itself, and we expect significantly higher losses in lower-quality credit such as leveraged and private direct lending," the team led by former Federal Reserve Vice Chair Richard Clarida, global fixed-income chief investment officer Andrew Balls and CIO Dan Ivascyn said in the firm's 2026 outlook.

The $2.27 trillion asset manager said credit markets are pricing in a benign outcome even as stress signals mount in direct lending, including rising shadow default rates and increased use of payment-in-kind features. Pimco's own analysis pegs AI-related debt issuance at roughly $100 billion per quarter as hyperscale operators finance data-center buildouts with leverage rather than cash on hand. The S&P 500 has gained 8% year to date, while the iShares iBoxx $ High Yield Corporate Bond ETF and the SPDR Bloomberg High Yield Bond ETF have posted flat returns, reflecting the divergence between equity optimism and credit caution.

For investors, the warning signals a regime shift after years of minimal credit losses. Pimco said high-quality fixed income now offers yields of 5% to 7% in local currency terms with lower volatility than long-run equity returns, arguing that portfolios should return toward the traditional 60% stock and 40% bond balance after leaning heavily into equities. "This argues for reconsidering portfolio allocations that were shaped during the low-yield, low-volatility decade following the global financial crisis," the Pimco team said.

Where Pimco sees opportunity

Pimco identified several areas presenting what it called "high-conviction opportunities." The firm favors intermediate-term bonds, citing an attractive balance of yield and risk in the five- to 10-year segment of global yield curves. Agency mortgage-backed securities also stand out, with spreads remaining wide relative to history and offering high credit quality backed by U.S. government guarantees through Fannie Mae, Freddie Mac and Ginnie Mae.

Global government bonds provide diversification as monetary policy paths diverge across countries, the firm said, while inflation-linked bonds and select real assets can buffer portfolios against geopolitical risks to energy prices. "Gold, in particular, has continued to serve as a neutral store of value in a world of partial confidence in fiat currencies," Pimco said. The firm also sees opportunities in asset-based finance, including equipment finance, consumer lending, residential mortgages and infrastructure credit, where collateral and cash flows are less directly tied to corporate earnings.

The AI credit conundrum

Pimco's warning comes as the firm itself has participated heavily in AI-related credit markets. In October 2025, Pimco closed a record $27 billion private-debt package to finance Meta's Hyperion AI data center, generating roughly $2 billion in paper profits. The firm said the opportunity set in AI-related credit is real but only for investors who can distinguish between well-capitalized borrowers with genuine revenue trajectories and overleveraged operators chasing a hype cycle.

"Even in a strong economy, AI will disrupt old economy companies, especially highly levered ones," Pimco said. The firm does not see an imminent equity correction but flagged that the Sharpe ratio indicates high-quality fixed income is now comparing favorably with stocks for the first time in years. Artificial intelligence could add $14 trillion to global capital spending over the next five years, Pimco estimated, with a productivity payoff that may arrive faster and prove more disinflationary than investors expect.

What comes next

Pimco said the dollar should remain the dominant global currency, giving the U.S. more flexibility than other sovereign issuers, and it does not foresee a U.S. fiscal crisis despite elevated debt and persistent deficits. Central banks have much more room to cut rates in future economic downturns than in the decade before the pandemic, the firm said, and it expects them to use that flexibility.

Geopolitics, domestic politics and industrial policy have become central drivers of growth, inflation and market returns, Pimco said, implying higher volatility and greater dispersion in returns across asset classes. "The cost of complacency has surged," the firm wrote. "Investors can no longer rely on outdated assumptions about globalization, policy backstops and suppressed volatility."
