The financial safety net that advisors have long counted on is quietly eroding. As non-bank financial institutions (NBFIs) expand their role in lending and market-making, the Federal Reserve's capacity to intervene during downturns has become less certain, leaving client portfolios more exposed to liquidity shocks than in past cycles.
New York Life Investment Management (NYLIM), which managed roughly $838 billion in assets as of June 30, 2026, calls this a structural turning point. In its 2026 Megatrends report, released October 5, 2026, the firm argues that the U.S. has moved into a market-led liquidity era, where capital flows are driven less by the Fed or commercial banks and more by a sprawling network of private credit funds, hedge funds, insurers, and pension funds.
For independent advisors, the shift demands a fresh approach to portfolio construction and risk assessment. "Investors have traditionally thought about liquidity as a characteristic of an asset or investment vehicle," said Julia Hermann, Global Market Strategist at NYLIM. "We believe it increasingly needs to be understood at the portfolio and financial-system level."
Three eras of liquidity
NYLIM's research traces three distinct phases since the 1980s: a bank-led regime before the 2008 financial crisis, a central bank-led era defined by quantitative easing, and the current market-led period. Post-crisis rules under Dodd-Frank and Basel III forced banks to slash risk-taking; dealer inventories of structured and corporate credit, which had peaked near $300 billion, collapsed to about $50 billion by the end of 2018. Non-bank players filled the void.
Today, private non-official investors hold roughly 60% of outstanding U.S. Treasury debt, up from 37% in 2014, according to NYLIM's analysis of Federal Reserve and Schwab Center for Financial Research data. Principal trading firms now account for about 60% of volume on electronic interdealer Treasury platforms—functions that bank-affiliated dealers once dominated.
What advisors need to know
The practical takeaway: liquidity can no longer be assumed to be uniform across a portfolio in times of stress. Because NBFIs operate largely outside the Fed's formal support infrastructure, the implicit backstop that markets relied on for decades is less predictable. "In today's fragmented financial architecture, liquidity in fixed income markets is not merely a risk constraint—it is a strategic asset," said Michael DePalma, Co-Head of Global Fixed Income at MacKay Shields, NYLIM's fixed income affiliate. "We structure our multi-sector portfolios with explicit liquidity tiers that act as operational pressure valves."
That framing matters for client conversations, especially for advisors navigating active ETF adoption and semi-liquid fund structures. The market environment has changed structurally, not just cyclically.
Three shifts to watch
NYLIM flags three developments reshaping investor behavior. First, the growth of secondaries, continuation vehicles, and evergreen funds. Assets in evergreen structures—open-ended wrappers around illiquid assets—grew from about $271 billion in 2022 to roughly $607 billion by 2026, according to PitchBook and Morningstar data cited by NYLIM. These vehicles offer new ways to transfer exposures but do not change the underlying illiquidity of the assets.
Second, digital asset infrastructure. Tokenization and stablecoin-based settlement can improve asset mobility, but NYLIM draws a sharp line between mobility and true market liquidity. The ability to transact without moving prices still depends on willing buyers and sellers—something tokenization alone cannot guarantee.
Third, the rise of the Total Portfolio Approach (TPA) among institutional investors. TPA abandons traditional asset-class sleeves in favor of managing risk and liquidity across the entire portfolio. A 2024 Thinking Ahead Institute survey found 20 of 26 major pension and sovereign wealth funds were already at or moving toward maximum TPA use. CalPERS voted in November 2025 to adopt TPA, becoming the first U.S. public pension fund to do so, according to NYLIM.
The Fed backstop question
The report's most consequential point may be its analysis of crisis response. Under the old bank-led regime, depository institutions had standing access to the Fed's discount window and FDIC insurance. That infrastructure worked in March 2023, when Silicon Valley Bank and Signature Bank failures triggered discount window borrowing that spiked past $150 billion. But with NBFIs now central to market liquidity, the Fed's toolkit is less directly applicable, leaving a gap that advisors must plan for.
For advisors, the message is clear: liquidity is a strategic asset, not a given. As asset owners shift allocations and direct indexing adoption grows, understanding where liquidity truly resides—and where it may vanish—is essential to building resilient portfolios.
