The Great Illiquidity Crisis Nobody's Talking About

On the surface, markets may currently appear to be calm, almost suspiciously so. While the S&P 500 continues to push higher, volatility has decreased to near post-pandemic lows, and capital is trickling back into risk assets that were recently under pressure. To the casual observer, it feels like stability has returned. But that calm is deceiving.

Beneath the headlines, market liquidity is quietly deteriorating. Bid-ask spreads are widening in places that used to be tight. Treasury auctions are growing more volatile and trading volumes in key segments are thinning out. It has not yet shown up in the VIX or mainstream coverage, however, the structural cracks are there.

This isn’t about price action or investor sentiment. It’s about how the system itself moves capital. When liquidity begins to vanish, markets can grind to a halt or even break entirely. This has been seen before and the early signs are starting to show again. The risk right now isn’t a crash that can be predicted, but rather one that comes from nowhere, because the market simply stops working.

Where Did All The Liquidity Go?

A big part of the liquidity drain comes down to the Federal Reserve’s quantitative tightening program. The Fed has slowly reduced trillions in assets since 2022, bringing its balance sheet down to around $6.7 trillion. That’s a significantly large reduction in reserves, reserves that used to support everything from basic credit expansion to asset market stability.

Banks haven’t exactly helped either. After the regional banking crisis in 2023, when Silicon Valley Bank and others unraveled almost overnight, lenders tightened up quickly. Regulators stepped in with new rules pushing mid-sized banks to carry more long-term debt and capital, but that also left them less able (or willing) to lend. As outlined here, these measures may have added some stability, but they’ve come at a cost.

Even the Treasury market, normally considered highly liquid, is showing signs of stress. When swap-spread trades started to unwind, volatility jumped and the dislocations were enough to raise alarms at the Fed itself.

Another pressure point is the repo market. As dealer balance sheets hit their limits, repo activity has become more limited. A Federal Reserve analysis shows just how much liquidity has weakened across key segments, even though demand hasn’t gone anywhere.

This is where it gets dangerous. Central bank liquidity like reserves and policy moves is only one side of the equation. The other side is private market liquidity, and that depends on functioning intermediation. Once both are under pressure, the entire system becomes vulnerable, even if prices still seem relatively stable.

While treasury auctions remain orderly, subtle signs of strain are emerging. On June 11, the U.S. Treasury sold $39 billion in 10‑year notes at a 4.421% yield, notably lower than pre-auction forecasts, evidence of firm demand. However, only 9% of the issue was absorbed by primary dealers, down from the recent six-auction average of 12.3%, signaling weaker dealer participation. The bid-to-cover held at a solid 2.67x, just above the typical six-month norm, reflecting reliable auction clearance but not true demand strength.

While the S&P 500 continues to climb, cracks are appearing beneath the surface. For the week ending June 10, the CME E‑mini S&P 500 dealer spread surged to 206,280, compared to 47,729 a year earlier, a staggering 332% increase. Such a sharp widening signals significant dealer caution and thinning liquidity. A spread of this magnitude implies that market makers now demand much more compensation to absorb risk, meaning even modest orders can move prices more than in the past. In the current environment, execution risk is rising, and liquidity appears increasingly fragile.

The ETF Mirage

Another overlooked aspect of today’s liquidity problem is within the ETF market. ETFs suggest stability on the surface in the form of steady inflows, strong pricing, and broad exposure. But underneath the structure is more fragile than it appears.

Unlike direct stock or bond purchases, ETF trades don’t necessarily reflect real buying or selling of the underlying assets. What gets exchanged are shares of the fund itself, not the securities it holds. That disconnect creates a false sense of liquidity as prices can appear stable even when the underlying market is thin or stressed.

Retail flows play a big part here. Inflows into passive products, especially equity ETFs, have remained strong despite tighter credit conditions and falling market depth. That demand can temporarily increase prices, making everything look healthier than it is.

The Real Danger

But the risk is that these flows suddenly reverse. When everyone sells at once, there may be no buyers for the underlying assets. This can lead to what traders call “air pockets,” which are moments where price gaps suddenly lower, and liquidity vanishes. It’s not just a theoretical risk. This has played out previously in high-yield credit and even in Treasuries during previous stress events. It’s a structural vulnerability that’s easy to overlook until it’s too late.

Stress in CRE Markets

Higher interest rates are weighing heavily on commercial real estate. A big portion of the sector relies on regular refinancing, and with over $1.5 trillion in CRE debt maturing by the end of 2025, many owners are now facing tougher terms and shrinking margins. In some cases the math simply doesn’t work, property values have declined, but debt costs have gone up.

Office buildings have been hit hardest, with a commercial real estate collapse looming. Vacancy rates in major cities like San Francisco and Chicago are climbing, and landlords are struggling to fill space. Even newer developments aren’t immune and lenders are becoming more cautious, with commercial mortgage-backed securities reflecting that shift. Delinquency rates have started to rise, particularly for office loans, and the refinancing window is narrowing.

In markets where asset values are falling and tenant turnover is high, some property owners are leaning on outside management to stabilize operations. Industry research and HUD data suggest that professionally managed single-family rental properties tend to report lower vacancy rates compared to national averages. In tighter markets, that operational stability can help preserve cash flow, especially in buildings with higher turnover.

With refinancing windows narrowing, many property owners are turning to operational tactics as a last line of defense. The emphasis on securing professional property management is no longer about optimization but survival, a change reflected in the forensic level of due diligence now applied to potential partners. The questions to ask a property manager now center on tenant retention and immediate cost control, reflecting a broader shift toward operational stability in high-risk markets.

This defensive posture is reshaping what metrics matter. Fee transparency, once buried in the fine print, is now front and center in investor assessments. Some contracts in today’s market list 20 to 30 separate ancillary fees layered onto base services, costs that may appear incremental in isolation but compound sharply across multi-unit portfolios. In a market where income stability is fragile, these add-ons are no longer tolerable blind spots, they’re risk variables.

Owners are adjusting accordingly. Rather than defaulting to full-service providers based on brand or convenience, they’re drilling into contract structures, seeking predictable cost models that align with cash flow preservation.

According to the National Apartment Association, landlords can spend around $4,000 every time a tenant leaves, between loss of rent, repairs, and the cost of finding someone new. It adds up quickly, especially when vacancies are already hard to fill.

That’s why a lot of owners are leaning on property managers to help reduce turnover. A good manager doesn’t just find tenants but they manage to keep them. When the day-to-day is handled well, leases are more likely to renew, and buildings stay occupied. It’s not a fix for everything, but in this market, stable income beats constant turnover.

Partnering with a professional property management company may not solve the refinancing problem, but it can reduce friction, limit downtime, and preserve rental cash flow, especially in buildings facing above-average turnover. As liquidity continues to tighten, CRE isn’t just a story about falling prices but rather a test of who can adapt and stay above water.

Consumer Credit Tightening

The liquidity crunch isn’t just showing up on bank balance sheets, it’s starting to also affect consumers. In the first quarter of 2025, total credit card balances fell by $29 billion, and auto loan balances dropped by $13 billion. That might sound like consumer debt is decreasing, but in reality, access to credit is shrinking. The New York Fed’s latest data puts the average perceived rejection rate for auto loans at 33.5%, which is the highest since the survey began. More people are being turned away or not even applying at all.

That hesitation matters. The share of “discouraged borrowers”, people who need credit but expect to be denied, has climbed to 8.5%. And banks are making it harder to borrow across the board with hoarding liquidity and tightening standards wherever possible.

It’s already starting to show in spending. Retail sales in early 2025 came in below expectations, even among higher-income households. That slowdown feeds into broader economic momentum. When credit dries up, households pull back and ultimately velocity slows. That eventually forces a repricing not just of risk, but of growth itself.

What Breaks First? Scenarios to Watch

If liquidity continues to tighten, certain parts of the market are more likely to deteriorate before others. For one, the Treasury market has already shown signs of strain. Dislocations in long-duration bonds, swap spreads, and auction volatility are starting to challenge the assumption that the U.S. government debt is risk-free and frictionless to trade.

Corporate credit is another pressure point. Many companies took on low-cost debt between 2020 and 2022. Now as that debt starts to mature, refinancing is becoming more expensive and in some cases completely unavailable. This is especially true in high-yield markets, where ETF structures could be tested. If redemptions rise, liquidity mismatches may force funds to limit or delay withdrawals.

Real estate is also a concern. A sharp enough decline in commercial property values can trigger municipal revenue declines, especially in cities dependent on property taxes and business district activity.

The risk here is sudden and not a slow deterioration. Illiquidity doesn’t build evenly, it sits quietly, then snaps. And when it does, multiple parts of the system can go at once.

Final Thoughts

If there’s another failure in the system, it may not start with a crash but rather with a freeze. Liquidity is what keeps everything moving and not just a technical metric. When that flow stops, price discovery disappears, and the ability to exit a position becomes a luxury.

This isn’t about fear or volatility spikes. It’s about what happens when markets stop functioning and transactions can’t clear. Investors and institutions should be thinking beyond sentiment and preparing for scenarios where selling it’s not just costly, but it’s not possible.

Because in the end, markets don’t crash when people are scared. They crash when there are no buyers.
