Wheat and
Chaff:
Global Liquidity,
Interest Rates,
and the Bears
Who Keep
Getting It Wrong.

Before the bears vs bulls argument —
understand what moves
every market on earth.

Global liquidity is the single most important variable in financial markets that most investors never consciously track. It is not the price of any asset. It is not the earnings of any company. It is the total amount of money available in the global financial system — the ocean in which all assets float. When the ocean rises, all boats rise. When it falls, even strong boats struggle. Understanding where global liquidity is, where it is heading, and what drives it is not optional financial knowledge. It is the foundational framework without which every other market analysis is incomplete.

The simplest measure of global liquidity is M2 — the broad money supply that includes cash, checking deposits, savings accounts, and money market funds. As of May 2026, US M2 alone stands at $23,052.3 billion — $23 trillion. Add the Eurozone, China, and Japan, and total global M2 from the world's four major central banks approaches $110 trillion — roughly equivalent to the entire global GDP. This is the pool from which all investment flows. When central banks expand this pool — by cutting rates, buying bonds, or injecting reserves — money looks for returns and asset prices rise. When they contract it — by raising rates, selling bonds, or draining reserves — money becomes scarce, the cost of capital rises, and asset prices fall.

The transmission mechanism has a specific lag that most investors miss. Changes in central bank balance sheets typically take 6 to 12 months to influence M2 aggregates, which then impact markets within up to 3 months. This means the liquidity conditions in markets today were set by central bank decisions made 6 to 15 months ago. And the liquidity conditions of the next 12 months are being set by decisions being made right now — by the Federal Reserve, the ECB, the Bank of Japan, and the PBOC. Understanding those decisions is understanding the future of every market.

The dotcom comparison.
It is not wrong.
It is incomplete.

The bear case on AI and current equity valuations is not stupid. It is articulate, data-supported, and made by serious people who have been right about markets before. The argument runs as follows: AI valuations are based on future earnings that may not materialise at the scale currently priced. The Nasdaq at 30× earnings is expensive by historical standards. The concentration of returns in a small number of mega-cap AI names resembles the concentration that preceded the dotcom collapse. Interest rates remain elevated, making the present value of future earnings lower than they were in the zero-rate era. And the history of transformative technology suggests that the companies that eventually dominate rarely include those that were most valued at the beginning of the cycle.

All of this is true. And the dotcom parallel has specific accuracy: in 2000, the internet was genuinely transformative — and most of the companies that investors bid to extraordinary valuations in 1999 either went to zero or produced mediocre returns for a decade. Amazon fell 95% from its peak. Cisco, at its 2000 peak, was valued so far ahead of its earnings that it took 25 years to recover those levels. The technology was right. The valuations were catastrophically wrong for most of the stocks that participated in the rally.

But here is what the dotcom comparison misses — and this is the critical distinction. In 2000, the internet companies being valued at extraordinary multiples were almost entirely pre-revenue, pre-profit, and in many cases pre-product. Pets.com. Webvan. Boo.com. These were business plans masquerading as businesses. The Nasdaq of 2026 is dominated by companies with actual revenue, actual profit, actual free cash flow, and actual moats. Microsoft is growing revenue at 15%+ and generating $90 billion in annual free cash flow. Nvidia reported $44 billion in quarterly revenue in Q4 2025. Alphabet generates over $100 billion annually in operating income. These are not valuations attached to hopes. They are valuations attached to businesses that are compounding at extraordinary rates.

Below-average growth.
But not contraction.
The distinction matters enormously.

The current state of global liquidity, as of June 2026, is best described as a slow expansion in a higher-rate environment. Three-month global M2 growth at constant exchange rates registered 1.44% in the period to April 2026 — below historical averages, but positive. This is not the liquidity contraction that produces crashes. It is the modest liquidity expansion that produces grinding, selective gains — where the companies with the strongest fundamentals continue to perform while the speculative fringe underperforms. This is exactly the wheat-separating-from-chaff environment.

The Fed's decision to pause quantitative tightening in December 2025 and launch Reserve Management Purchases — buying $40 billion in Treasury bills per month — was a stealth liquidity injection that most commentary missed. It is not QE. It does not have the same expansionary power as the post-2008 or post-COVID asset purchase programmes. But it represents a shift from active tightening to passive stabilisation — and that shift, with the 6-to-15-month transmission lag, will show up in M2 and market liquidity through the second half of 2026 and into 2027.

In a tight liquidity environment,
the market does the work
that euphoria didn't do.

The phrase "separating the wheat from the chaff" comes from the ancient process of threshing grain — beating harvested grain to loosen the edible wheat kernels from the inedible husks (chaff), then throwing it into the wind so the chaff blows away and the wheat falls. The market does exactly this when liquidity tightens. When money is free and abundant, everything goes up — quality companies and speculative concepts alike. When money becomes expensive, investors stop paying for hope and start demanding substance. The chaff blows away. The wheat falls where it belongs.

The most important variable
for every portfolio
is not AI. It is this.

The most important single variable for global financial markets over the next 18 months is not the speed of AI adoption, not geopolitical developments, not corporate earnings. It is the interest rate path of the Federal Reserve — specifically, when the first rate cut comes, how many follow, and at what pace. Everything else is downstream of this.

The common thread across all three scenarios is the importance of quality. In Scenario A, quality assets re-rate most. In Scenario B, quality assets outperform through earnings growth while speculative assets decay. In Scenario C, quality assets recover fastest from the drawdown. The bear who is waiting for the correction before buying quality is solving the wrong problem. The question is not "when does the market correct" — it is "what do I own when it does." The correction, when it comes, is an opportunity in the wheat and a warning in the chaff. Distinguishing between the two before the correction happens is the entire game.

The verdict.
