How the USA Political Instability Index works, how it compares to other US
political stability trackers like the World Bank's index, FEMA's National
Risk Index, and the Fed's Geopolitical Risk Index, and how to read its six
daily-updating composite scores.
Geopolitical Risk
What's the difference between the Caldara-Iacoviello Geopolitical Risk Index and a real-time geopolitical risk tracker?
The Federal Reserve's GPR Index (hosted at PolicyUncertainty.com) counts geopolitical-conflict language across 10 major newspapers, updated monthly. The USA Instability Index's Geopolitical Risk variant instead blends daily market signals (yen/dollar volatility, defense-sector relative performance), a global event feed (GDELT), and daily Google search behavior (war, military draft, drone warfare, emigration searches) — all normalized to a historical percentile and updated daily rather than monthly. Think of GPR as a slower-moving, media-based baseline and this index's Geopolitical Risk score as a faster-moving, behavior-and-market-based read on the same underlying phenomenon.

Do Google searches for "war" actually predict geopolitical instability?
Not on their own — search volume is a lagging or coincident behavioral signal, not a predictive one. The USA Instability Index treats war-related search interest as one of 24 inputs, always normalized against its own 2004-present percentile history rather than read as a raw number. A spike matters more in combination with market-priced signals like yen volatility or defense-sector performance than in isolation.
What does yen strength have to do with geopolitical risk?
The Japanese yen is widely treated as the world's premier safe-haven currency, so sharp yen appreciation against the dollar tends to mean global investors are de-risking — often in response to a geopolitical shock rather than a domestic one. That's why JPY/USD volatility carries meaningful weight in the Geopolitical Risk composite specifically, separate from its smaller role in the Overall index.
Market Risk & Recession Signals
Is a VIX reading above 30 a recession warning sign?
A VIX above 30 signals elevated fear and expected volatility in S&P 500 options pricing, and levels below 20 typically mean a calmer market — but VIX alone isn't a recession call. The USA Instability Index gives VIX one of its largest weights inside Market Risk, alongside 2-year Treasury volatility, the Buffett Indicator (market cap-to-GDP), and CPI volatility, because market stress signals like these tend to cluster rather than move independently.

What is the Sahm Rule and does this index track it?
The Sahm Rule flags a recession's start when the three-month moving average of the U3 unemployment rate rises 0.5 percentage points or more above its low point in the prior 12 months. The USA Instability Index doesn't run the Sahm Rule's exact triggering logic, but it does track the same underlying labor-market data — the prime-age (25-54) employment-population ratio, inverted so that falling employment raises the instability score — as one of its highest-weighted Domestic Strife inputs.

Does the USA Instability Index use the same recession definition as the NBER?
No — the NBER declares recessions retrospectively using a broad, judgment-based review of employment, income, spending, and production data, sometimes months after a downturn has already started. The USA Instability Index isn't a recession-dating tool at all; it's a same-day composite risk score. It does plot NBER-dated recession windows directly on its historical chart as a reference overlay, so you can see how the index behaved heading into past NBER-confirmed recessions.

What's the Buffett Indicator and why does it matter for market risk?
The Buffett Indicator is the ratio of total U.S. stock market capitalization (Wilshire 5000) to GDP — a high ratio implies equities are priced well above the size of the underlying economy, historically a precursor to corrections. It's one of the inputs in the Market Risk composite, sitting alongside VIX and Treasury volatility as one of the more valuation-based, versus purely sentiment-based, signals in that variant.
Political & Institutional Stability
How is the USA Instability Index different from the World Bank's Political Stability Index?
The World Bank-style Political Stability Index is an annual, expert-survey-based composite — it blends assessments from the Economist Intelligence Unit, World Economic Forum, and Political Risk Services, updated once a year on a -2.5-to-2.5 scale. The USA Instability Index takes a market-and-behavior-based approach instead: no direct expert-survey input at all, relying on daily-updating financial, search, and environmental signals normalized against their own historical distribution. The two answer a related but different question — perceived institutional stability versus revealed, day-to-day stress signals.

Is this a political stability index or a political instability index?
They're the same underlying measurement read in opposite directions. A rising score on the USA Instability Index means rising instability — the inverse of a traditional political stability index, where a rising score means more stability. The USA Instability Index frames the scale as instability because most of its inputs (market volatility, search-behavior spikes, drought coverage) are naturally higher-equals-more-stress metrics; inverting that into a stability score would require flipping half the inputs for no analytical benefit. So if you're looking for a US political stability index reading, take 100 minus the instability score as a rough stability equivalent.

Is there a real-time or daily US political stability index?
Most published political stability indices — including the World Bank-style index tracked by TheGlobalEconomy.com — update annually and rely on expert surveys, which means they can lag real-world events by months. The USA Instability Index is built specifically to close that gap: its Overall composite updates daily from market data, government economic releases, and behavioral search signals, going back to 2004. It isn't a direct substitute for an annual expert-survey index — it's answering a faster-moving version of the same underlying question.

What causes a sudden spike in a domestic-strife or protest-related index?
In the USA Instability Index, the Domestic Strife composite is led by the prime-age employment-population ratio and protest-related search volume, with therapy-search volume, CPI volatility, and gun-purchase search interest layered in behind. A spike typically reflects some combination of a weakening labor market and a surge in real-time public search behavior around unrest or economic anxiety, rather than any single triggering event.
Climate & Resource Risk
How is this different from FEMA's National Risk Index?
FEMA's National Risk Index is a static, periodically-updated dataset that scores expected annual loss, social vulnerability, and community resilience across 18 natural hazards at the county or census-tract level — built for long-range mitigation planning. The USA Instability Index's Climate Risk composite is a daily national-level score built from extreme-weather search volume, US Drought Monitor coverage, food-shortage search interest, a water-sector ETF's volatility, and energy price volatility — meant to capture near-term climate-linked stress rather than long-term structural exposure by location.

Can Google search volume for "drought" or "extreme weather" actually measure climate risk?
It measures public attention to climate risk, which correlates with — but isn't identical to — physical climate exposure. That's why the USA Instability Index pairs extreme-weather search interest with a hard physical dataset, US Drought Monitor coverage, rather than relying on search behavior alone.

Why would a water-sector ETF's stock volatility count as a climate signal?
The Invesco Water Resources ETF (PHO) holds companies focused on water treatment, infrastructure, and conservation — its price volatility is a market-priced proxy for investor uncertainty about water-resource availability and infrastructure spending. It's a long-leading indicator in the index's own terms: it tends to move on capital-allocation decisions before physical drought data catches up.
Economic Indicators & Data Sourcing
What official economic data feeds into a US instability index?
The USA Instability Index draws its macro inputs from FRED, the St. Louis Fed's database: 2-year Treasury yield volatility, VIX, CPI volatility, WTI crude oil volatility, the prime-age employment-population ratio, the Case-Shiller Home Price Index, and a Wilshire 5000-based market-cap-to-GDP ratio. For a broader, non-composited view of the same category of official releases — retail sales, housing starts, international trade, manufacturing — the Census Bureau's Economic Indicators briefing room is the primary federal hub.

How do you combine data as different as stock volatility and Google search trends into one score?
Every raw input — regardless of its native unit — is converted to a 0-100 score using its own historical percentile rank against a 2004-to-present baseline. A score of 50 means today's reading sits at the historical median for that specific input; a score of 90 means it's in the top 10% of readings ever recorded for that input. Because every input lands on the same 0-100 scale by construction, they can be combined into a weighted composite without one unit dominating another. See the full methodology.
Why does the index only go back to 2004?
2004 is when Google Trends data begins, and the index anchors all inputs — including purely financial ones like VIX or Treasury volatility, which have much longer histories on their own — to the same 2004-start baseline. That keeps every percentile score comparable across categories; if the financial inputs used a longer baseline than the behavioral ones, a score of 50 on one input wouldn't mean the same thing as a 50 on another.
