Liquidity Blind Spot: Money Supply Risks for 2026 Markets

1. Everyone watches rates. Few watch money.

Central banks have spent two years at the centre of every macro conversation. Policy rates, dot plots and speeches dominate headlines; liquidity, by contrast, has slipped quietly into the background. Yet as of late 2025, U.S. M2 money supply is growing around 4.3% year‑over‑year—faster than both CPI inflation (about 2.7%) and real GDP (roughly 2.3%).

That gap matters. When money expands faster than the real economy, the excess tends to show up somewhere—often in asset prices, sometimes with a lag and in places investors are not immediately looking.

2. A slow‑motion shift from quantitative tightening to quiet accommodation

On paper, central banks are still in a post‑tightening stance. Policy rates remain well above pandemic lows, and balance‑sheet runoff continues in some jurisdictions. Under the surface, though, liquidity conditions have started to ease:

Money growth has turned positive again after a rare contraction, driven by a mix of bank credit, fiscal deficits and slowing QT.
Fiscal policy remains expansionary in many economies, adding to private‑sector cash balances even as headline budgets talk about consolidation.

The result is a “liquidity asymmetry”: the public narrative focuses on restrictive policy, while the plumbing shows more cash gradually seeping back into the system. That disconnect is fertile ground for mis‑pricings.

3. Tariffs and the inflation optics problem

Overlaying this liquidity story is a new inflation wrinkle: the tariff shock. Some research expects U.S. inflation to climb from about 2.7% to around 3.4% in early 2026 as higher import costs feed through to consumer prices. Crucially, this looks like a level effect rather than a renewed spiral—core pressures and expectations remain contained, and inflation is still projected to ease back toward 2% by the end of 2026.

But optics matter. A visible uptick in headline inflation, combined with still‑elevated policy rates, could encourage investors to underestimate how supportive underlying liquidity has become—or push central banks to lean more hawkish than the macro data alone would warrant.

4. Why this matters for banks and markets

For banks, a world of quietly expanding money supply and tariff‑distorted inflation presents both opportunity and risk:

On the one hand, stronger liquidity and softened capital rules create room to grow balance sheets, support credit and monetise market‑making as volatility flares.
On the other, mis‑reading the liquidity cycle can leave institutions over‑exposed to rate and credit shocks if central banks are forced into a second round of tightening later in the decade.

For markets, the key takeaway is that valuations may be more sensitive to liquidity than to modest changes in policy rates alone. Equity and credit rallies can persist even when rates are high, so long as money and credit aggregates are expanding faster than the real economy. The danger is assuming that “restrictive” rates automatically mean scarce liquidity.

5. A framework for 2026: follow the money, not just the message

To avoid the liquidity blind spot, banks and investors can:

Track money and credit aggregates—M2, bank lending, shadow‑credit indicators—alongside traditional macro data like CPI and unemployment.
Map how liquidity flows through different channels: central‑bank balance sheets, fiscal deficits, bank credit and non‑bank financing.
Stress‑test portfolios not only for rate and growth scenarios, but for different liquidity regimes—from slow drip easing to sudden stops.

In a year when the consensus narrative is all about “higher for longer” giving way to “cautious easing”, the more interesting question may be: how much hidden easing is already in the system, and where is that liquidity going to land first?
