Why it matters for Bitcoin: A stronger dollar historically pressures Bitcoin. When the dollar rises, risk assets face headwinds — investors move toward dollar-denominated safety. When the dollar weakens, capital rotates into hard assets and risk-on plays. DXY is one of the four core macro signals in BSI. BSI uses the 60 trading-day rate of change (~3 calendar months) to filter out daily noise.

Why it matters for Bitcoin: Since 2020, Bitcoin and NASDAQ have traded with historically high correlation. The same institutional desks that manage tech portfolios also manage Bitcoin exposure. When they sell tech, they sell Bitcoin. When they buy tech, Bitcoin benefits. A strong NASDAQ means institutions are comfortable with risk — and that environment historically supports Bitcoin. BSI uses the 20 trading-day rate of change (~1 calendar month) to capture recent institutional momentum.

Why it matters for Bitcoin: High VIX creates risk-off conditions across all markets. When VIX spikes, investors sell risky assets — and Bitcoin gets sold. Conversely, a calm VIX signals institutional money is comfortable staying in risk assets. BSI triggers a hard cap when VIX exceeds 35 — in true panic conditions, no composite score should read STRONG regardless of other signals.

Why it matters for Bitcoin: Rising yields hurt risk assets. When the 10-year goes up sharply, money flows from speculative assets into bonds — you can now earn a real return in safety. 2022 proved this definitively: yields rose from near zero to 4%+ and Bitcoin fell 75%. Falling yields push capital toward risk assets in search of returns. BSI measures the raw percentage-point change over 65 trading days (~3 calendar months) — not a % return, but the actual move in the yield itself. A move of more than 0.25 percentage points in either direction is enough to register a headwind or tailwind.

Why BSI uses it differently: Most tools take Fear & Greed at face value. BSI uses it as a contrarian signal. Extreme Fear (below 25) has historically marked near-term lows — when everyone panics, that is often worth paying attention to. Extreme Greed (above 75) signals caution — euphoria often precedes tops. This is weighted at only 8% because sentiment alone is never the whole story. Macro context always outranks mood.
