Sideline Cash Ratio (Cash vs US Equity Market Value)

The sideline cash ratio divides total US cash balances — money-market fund assets plus commercial bank deposits — by the market value of all publicly traded US corporate equities, from the Federal Reserve's Z.1 and H.8 releases. It is the free, reproducible version of the Bloomberg "cash as a percent of S&P 500 market cap" chart; because the denominator here is the whole public equity market rather than the S&P 500 alone, the levels print lower, but the shape and the extremes are the same. The record low came in early 2000 at the dot-com peak; the record highs came in 1982 and early 2009 — the two great generational buying points.

Latest reading

As of January 2026, Sideline Cash (Cash ÷ equity market value) stands at 0.34 — up from 0.32 the prior reading. Read it as a slow contrarian valuation gauge: extremes matter, the middle does not. Very low readings (under ~0.39, the bottom decile) mean equities are enormous relative to the economy's cash buffer — 2000, 2021, and today. Very high readings (above ~0.83) have marked washed-out markets. One warning baked into the design: this is NOT "dry powder waiting to buy stocks." The cash pile in dollars almost never shrinks — the ratio falls because market cap grows, and in aggregate cash cannot "flow into" equities, since every buyer of a share hands their cash to a seller. A low ratio says valuations are stretched relative to liquidity; it says nothing about when that matters. Series history runs from 1973 to present.

Total cash pile

The numerator in dollars: total money-market fund assets plus commercial bank deposits. The cash pile almost never shrinks — the ratio falls because the market grows faster, not because cash is spent.

US equity market value

The denominator: the market value of all publicly traded US corporate equities from the Fed's Z.1 accounts — a broader (larger) base than the S&P 500's market cap alone.
