claude-opus-4-8SPX vs 10Y yield 60-day correlation back to strongly negative at -0.59, a regime shift from last year's near-zero/positive readings.
The only correlation pair reported this run is SPX vs 10Y yield: the current 60-day rolling Pearson correlation of daily SPX log-returns against daily 10Y Treasury yield changes is -0.5887 as of 2026-07-14. That is meaningfully negative, meaning stocks and yields have been moving in opposite directions — rising yields coinciding with falling equities (a "bad" rate-driven regime for stocks). This is a notable shift from the provided history, which sat around -0.33 in mid-July 2024, crossed to roughly zero in early August 2024, and drifted positive (+0.10 to +0.21) through September–October 2024. In other words, the market has moved from a benign/positive stock-bond return relationship a year+ ago to a distinctly negative one today. The bulk of the history array is truncated, so I cannot confirm the exact path between late-2024 and now.
CONDITIONAL ACTIONS
Treat the current -0.59 reading as a rate-sensitive equity regime: if the 60-day correlation stays below roughly -0.5, monitor 10Y yield moves as a primary near-term driver of equity direction, since rising yields have been coinciding with equity weakness.
MEDIUMbasis: current_60d = -0.5887
If the correlation mean-reverts back toward zero or positive (as it did in Aug–Oct 2024, +0.10 to +0.21), the stock/bond diversification benefit weakens and equities become less directly hostage to rate moves — watch for that transition.
MEDIUMbasis: history values +0.0003 (2024-08-08) rising to +0.2096 (2024-10-04)
Because only one pair (SPX vs 10Y) is populated this run, avoid drawing broad cross-asset conclusions; seek the other correlation series before acting on portfolio-level hedging.

CAVEATS
- ·The history array is truncated after October 2024, so I cannot verify how correlation evolved into 2026 or confirm the exact recent trend leading to -0.5887.
- ·Only one correlation pair (SPX vs 10Y) was provided; the page's 'cross-asset' scope is otherwise unpopulated this run.
- ·A rolling 60-day Pearson correlation is a backward-looking summary statistic and does not indicate causation or predict future co-movement.
- ·The latest datapoints shown in-history are from 2024; the current -0.5887 is dated 2026-07-14 but the connecting data is not visible.

ACTIVE REGIME — EQUITY DOMINANCE
Equity dominance: equities absorbing rate and FX noise — AI trade is the dominant market theme
Equities move against both rates and the dollar simultaneously. The AI/growth trade is the dominant market theme — equities absorb macro noise. SPX/10Y: -0.61 · SPX/DXY: -0.52 · Yield/DXY: +0.52.

Zones apply to the SPX pairs: green (below −0.50) = equity dominance · red (above +0.20) = regime stress. Yield/DXY runs opposite — positive coupling confirms the regime.
SIGNAL — EQUITY DOMINANCE
Equity dominance: equities absorbing rate and FX noise — AI trade is the dominant market theme
- ›When SPX moves strongly against both rates and the dollar simultaneously, equities are the driver — macro factors are noise relative to the AI/growth narrative.
- ›SPX currently carries the largest and most consistent loading in the correlation matrix — it's moving against both rates and the dollar, meaning the equity/AI-capex narrative is absorbing macro noise rather than reacting to it.
- ›This regime is self-reinforcing as long as AI capex commitments remain non-discretionary. Hyperscaler spending does not ebb with quarterly sentiment shifts.
- ›Primary stance: continue buying dips in equities. The regime breaks when the SPX/10Y correlation moves toward zero or turns positive — that is the early warning signal.
- ›Watch the Yield/DXY correlation: a reading above +0.70 means rates and the dollar are tightening in lockstep. That is the regime backdrop that eventually chokes equity momentum.
HOW TO READ THIS TOOL
SPX vs 10Y Yield
The most important correlation. When deeply negative (−0.6), equities and rates move in opposite directions — good macro news (lower yields) = equities up, or bad macro (higher yields) = equities down. This inverse relationship is the hallmark of a rate-driven or growth-driven regime. When it turns positive, the regime has shifted: equities and rates rising together means the market is pricing nominal growth (inflationary) or fear of tighter financial conditions overriding the growth story.
SPX vs DXY
Measures risk appetite on a global scale. A negative SPX/DXY correlation means dollars are flowing into risk assets and out of the safe-haven dollar — the classic risk-on signal. This is consistent with the AI capex cycle pulling global capital into US equity markets. A turning positive SPX/DXY correlation can signal dollar strengthening on fear (flight to safety) while equities also fall, or alternatively a synchronized global growth rally (rare).
10Y Yield vs DXY
When rates and the dollar move together (positive correlation), the US is in a tightening regime: higher rates attract capital, strengthening the dollar. A reading above +0.70 suggests the tightening narrative is dominant. This is the backdrop where equity multiple expansion is hardest to sustain. The May 2026 reading of +0.81 confirms that the macro tightening dynamic is live underneath the AI equity narrative.
The Dominant Market Theme
The correlation matrix above shows SPX carrying the largest and most consistent loading against both rates and the dollar right now — equities are the driver, and rates/dollar are reacting to equities rather than vice versa. That's what the equity-dominance regime looks like when you make it visible through cross-asset correlation.
What to watch for: A weakening equity-dominance loading would show up as multiple competing narratives emerging simultaneously rather than one dominant theme — typically a volatility-expanding event. Monitor for the SPX/rates correlation crossing zero as the leading indicator.

METHODOLOGY
SPX — Yahoo Finance: ^GSPC. Daily log-returns (ln(Pₜ/Pₜ₋₁)) used to remove price-level effects.
10Y Yield — FRED: DGS10 (10-Year Treasury Constant Maturity Rate). Daily first differences used (Δyield).
DXY — Yahoo Finance: DX-Y.NYB (ICE US Dollar Index). Daily log-returns used.
Correlation method: 60-day rolling Pearson correlation on the above daily series, aligned by trading date intersection (inner join). Chart zones apply to the SPX pairs: green = Equity Dominance (below −0.50), red = Regime Stress (above +0.20). The Yield/DXY pair reads on an inverted scale — positive coupling is the normal macro linkage and confirms equity dominance; decay toward zero or inversion signals the macro regime fragmenting.
