SIGNAL OVERVIEW
Gold functions as an inflation hedge across long horizons. When inflation expectations rise sharply, institutional capital reallocates toward gold as a store of value. Robert Shiller created a long-term inflation-expectations series that combines market-implied breakeven rates with University of Michigan consumer survey data. This signal reads the Shiller series, forward-fills monthly data to daily, z-scores on a rolling window, and bounds through tanh. On October 10 2023 the composite reached its series maximum plus 1.0000 as post-pandemic inflation expectations peaked. On October 14 2014 the composite reached its series minimum minus 1.0000 during the deflationary-fear episode as oil prices collapsed. Phase +1 inflation-stress state has delivered plus 1.33 percent mean forward 60-day gold return versus Phase -1 disinflation-tilt plus 0.03 percent, a 130 basis-point edge. Today the composite reads -0.223, in Mild Disinflation Tilt territory.

STATE AND READING
Mild Disinflation Tilt, 19 days running. Composite at -0.223 is in the range.
WHY THE SIGNAL IS HERE
The underlying input is at its current level relative to the 504-day baseline. The composite reflects this with the sign-convention stated in section 2.
POSTURE FOR THE WEEKS AHEAD
The signal's historical edge is concentrated at the tanh-saturation extremes (composite below minus 0.5 or above plus 0.5). The cross-sample Pearson IC of +0.06 on SPY forward-sixty-day is a reference-asset read; the appropriate direct read is GC forward returns, which are not computed as a baseline in this page.
WHAT THE CHART SHOWS
Today the composite reads -0.223 placing the dot inside the Mild Disinflation Tilt band. Shiller series updates monthly; intra-month moves reflect forward-fill artifact rather than fresh data.

Scroll inside the table for the full history. Forward 60-day GC is measured from each run’s start date; a reader cannot trade off a start-date they only identify in hindsight, so this is a transparency log, not an alpha claim. Asterisked (*) returns are partial. The run is less than 60 trading days old. The full 60-day comparable fills in as more data arrives.
What this measures
Robert Shiller long-term inflation-expectations series combining breakeven rates with University of Michigan consumer survey data. The engine reads monthly data, forward-fills to daily, z-scores on a rolling window, and bounds through tanh. Elevated composite captures inflation-expectation stress regimes which have historically driven gold as inflation hedge.
Why it matters
When inflation expectations rise, institutional capital reallocates to inflation hedges including gold. The mechanism is institutional-asset-allocation driven at monthly-plus horizons.
Phase +1 inflation stress has delivered 130 basis-point edge on gold forward 60-day returns versus Phase -1 disinflation tilt. Pair with real-rate and credit-stress signals for a complete inflation-and-safe-haven view.
Shiller series updates monthly; intra-month composite moves are forward-fill artifacts not new information. Readers should anchor expectations around monthly release dates.
