Central bank analysis: hawk/dove scoring and language shift detection

What the tool analyzes

Hawk/dove scoring

Every central bank statement is scored on a hawk-to-dove spectrum based on the language used. Hawkish language (emphasizing inflation risks, policy tightening, overheating) receives a positive score. Dovish language (emphasizing growth risks, employment concerns, accommodation) receives a negative score. The composite score provides an objective measure of where the central bank stands - and more importantly, how that position has shifted relative to previous statements.

Language shift detection

The most important signal in central bank communication is not the absolute hawkishness or dovishness - it is the change from the previous statement. Markets price the current stance into forward rates. What moves markets is the delta - the shift.

The language shift detection system compares each new statement against the previous statement, identifying:

• New phrases introduced (signaling new concerns or priorities)
• Phrases removed (signaling diminished concerns)
• Qualification changes (adding or removing hedging language like "some," "modest," "considerable")
• Emphasis shifts (moving a topic higher or lower in the statement order)

Forward guidance extraction

Central banks communicate their intended policy path through forward guidance - language about future actions. The forward guidance extraction system identifies and categorizes these signals:

• Explicit guidance: "We expect to maintain the current rate for an extended period"
• Conditional guidance: "If inflation remains above target, further tightening may be appropriate"
• Data-dependent guidance: "Future decisions will depend on incoming data"
• Time-based guidance: "Through the end of the year"

Each type of guidance has different implications for how the market should price the rate path.

Central banks covered

Market Ontology tracks and analyzes communications from:

• Federal Reserve (FOMC statements, press conferences, speeches, minutes)
• European Central Bank (Governing Council statements, press conferences)
• Bank of Japan (policy statements, quarterly outlook reports)
• People's Bank of China (rate announcements, open market operations commentary)
• Bank of England (MPC statements, inflation reports)
• Additional central banks across major economies

Each central bank's analysis includes the current policy rate, the hawk/dove score, the language shift from the previous statement, and the implied forward guidance.

How central bank language transmits into markets

The transmission from central bank language to asset prices operates through several channels:

Yield curve: Hawkish shifts raise front-end yields (rate hike expectations) and can flatten the curve. Dovish shifts lower front-end yields and can steepen the curve. The magnitude depends on how much of the shift was already priced in.

FX: Central bank divergence (one bank hawkish while another is dovish) is the primary driver of currency pairs. A hawkish Fed + dovish ECB widens the rate differential and strengthens the dollar against the euro.

Equity multiples: Rate expectations directly affect equity valuations through the discount rate. A hawkish shift compresses multiples, particularly for growth and duration-sensitive sectors. A dovish shift expands multiples.

Credit spreads: Dovish shifts tend to compress credit spreads (easier financial conditions). Hawkish shifts tend to widen spreads (tighter conditions, higher default risk).

Volatility: Ambiguous or data-dependent guidance increases uncertainty, which elevates implied volatility. Clear forward guidance reduces uncertainty and compresses vol.

Current central bank divergence

Central bank policy divergence across the four major central banks (Fed, ECB, BoJ, PBOC) is currently at its widest since early 2022. The Hormuz crisis is deepening this divergence because different economies face different energy exposures, different inflation dynamics, and different growth vulnerabilities.

Tracking this divergence - and identifying when it narrows or reverses - is essential for FX positioning, carry trade management, and cross-border equity allocation.
