While assets in fixed-income funds climbed to $7.9 trillion as of May 31, their share of portfolios fell to 20.3% from 25.7% in 2016, and down 4.8% from 2025 as investors shifted toward equities and other asset classes, marking the lowest month-end concentration since May 2008, Morningstar data showed.
Over the long run, bond returns can be eroded by persistent inflation, a weakening currency, and supply outpacing demand, said Grant Johnsey, market solutions head at Northern Trust.
The Federal Reserve held rates steady at 3.50% to 3.75%, while yields are hovering around 4.6% on the 10-year and 5.1% on the 30-year, suggesting investors expect inflation to remain sticky and are demanding a premium for locking up money for longer periods.
In response to inflation concerns, some investors are turning to assets that can better preserve purchasing power in a world being shaped by deglobalization, supply constraints and higher defense spending.
Stephen Harvey, chief investment officer at Sagard Wealth Management in Toronto, said the world remains broadly "pro-growth, pro-inflation," and fiscal policy now matters more than monetary policy in shaping markets.
Sagard Wealth has spent the past year moving clients away from most developed-markets fixed income and into a "preservation bucket" mix of commodities, gold, real estate and infrastructure, with Harvey saying, "fixed income is the inflation loser."
Real assets, tangible assets valued for their intrinsic physical qualities, have been gaining appeal since the post-Covid inflation shock, with the case strengthening as the bond outlook clouds and soaring equity markets appear vulnerable, said Jenn Bender, global chief investment strategist at State Street Investment Management.
State Street has seen the strongest flows this year into commodities, with infrastructure and natural resources drawing interest. Its flagship real asset strategy drew about 6% in net inflows in 2025, with momentum continuing this year.
Performance through May 31 underscores the appeal. Broad commodities returned 23.2%, global natural resources 19%, and U.S. REITs 13.6%, according to State Street data, while U.S. Treasuries were flat.
"The worry is that there is some downside risk in equities. Fixed income is not the place that people want to move their equity allocations over to," said Bender. "Basically, real assets is kind of where you end up."
Investors move beyond bonds for inflation protection
Some U.S. investors who once relied on bonds to cushion equity selloffs are making more room for commodities, infrastructure, private credit and other inflation-sensitive assets to protect themselves against inflation.
Inflation, heavy government borrowing, policy uncertainty and bouts of stocks and bonds falling in tandem have weakened bonds' role as a ballast, prompting some investors to look for more diversification. At 3.5%, U.S. consumer inflation has eased, but escalating U.S.-Iran tensions threaten another oil-driven rebound in price pressures.
"Bonds only work as insurance in your portfolio when inflation is low," said Phil Blancato, chief market strategist at Osaic, a wealth management firm. Osaic cut fixed income in its 60/40 portfolio in recent weeks, to 31% from 40%, and added a 6% commodities allocation -- the first in 15 years -- noting that bonds have failed to provide sufficient downside protection during equity selloffs.
Fixed income is still present, but with less reliance on Treasuries
The stock-bond correlation tends to turn positive when inflation runs high, usually around 2.7%, investors said, except in recessions where Treasuries still provide a hedge. A positive correlation means stocks and bonds move in the same direction, which impacts portfolio diversification as investors get less protection against stock market losses.
Blancato said the firm is also shifting from passive fixed income to more active positions in collateralized loan obligations, mortgage-backed securities and high-yield debt, seeking better opportunities beyond Treasuries.
The Virginia Retirement System is keeping its 16% allocation to fixed income but boosting credit, private real estate and infrastructure, while exploring a higher policy leverage range to build resilience across different inflation scenarios, said deputy chief investment officer Chung Ma.
"We're just not necessarily relying on the negative correlations that we have historically seen," he added.
