Markets
The Velocity of Value
Layer 3 measures not a snapshot but how fast the world moves within a year. FX, interest-rate derivatives, equities, bonds, credit derivatives, repo, insurance and more: the markets where accumulated wealth, claims and expectations about the future are repriced and change hands.

Here the scale shifts again. The wealth Layer 2 shows is a stock; Layer 3 is the flow - how many times that stock moves over the course of a year.
A century ago the annual volume of financial-market trading was roughly the size of world GDP; by 2000 it was 27× GDP, today 82×. The world produces financial movement far beyond the value it owns.
Layer 3's question is no longer “How much wealth is there?” but “How do that wealth, those claims and those expectations move again within the year?”
How long is it held?
Average holding period per market (log time axis); dot size is annual trading volume. The largest flows sit at the fast end; almost nothing at the slow end.
The money that moves is fast: most trading volume is in FX and interest-rate derivatives that change hands within days. Big asset classes - homes, commercial property, art - are held for decades, so their flows are tiny. The same dollar of 'wealth' behaves completely differently depending on its wrapper.
What does the churn produce?
Gross trading volume versus the measured output of that churn - the value added of the finance and insurance sector itself.
Gross trading volume is 82, times the income the world produces and 13 times the net worth it owns. But the measured output of that churn - finance and insurance's own value added - is only %5,2of world GDP. The rest is not value creation but changing hands: 1.580 units of trading volume per 1 unit of value added.
Who does the trading?
Counterparty breakdown for the two markets that make up about 90% of trading volume (BIS Triennial Survey, April 2025).
In the two markets that carry most of the volume, the real economy (companies, non-financial institutions) is 2-5%. The rest is banks and funds trading with each other - Layer 3 is not 'the world shopping' but a closed loop among intermediaries.
This tower is not self-sustaining: the four layers are a closed loop. Mass pulled from the planet turns into the economy, the economy into wealth, wealth into markets, and the market still needs ore and fuel dug fresh without pause. The loop runs both ways: a strait closing sets a derivative price, an interest-rate decision decides which mine opens.
Annual market flow ($9.735 trillion) is 82,4× world output. A whole year's raw-material value changes hands at this speed in about 6 hours.
Layer 3 markets turn over about 82× world GDP in a year; the core workforce that runs them is roughly 1/191 the size of Layer 0's.

The grand loop of the four layers
Mass pulled from the planet turns into the economy, the economy into wealth, wealth into markets, each step multiplying the number. But the loop closes: the most abstract layer still feeds without pause from the first.
×18 value added · ×6 accumulation · ×13 turnover
Layer 3's 9.735 T $ of abstract flow a year rests on roughly 85 Gton of ore pulled from the ground that same year, and the energy to move it. There is no "just finance".
Four layers, one system: material is extracted, turns into value, accumulates, then moves again with no material stirring. The Big Picture →
