Pinpoint the main routes by which geopolitical risk moves asset prices and affects financial stability, and review policy responses to its possible fallout.
The idea
Geopolitical risk is usually measured with a news-based index that counts the share of newspaper articles discussing adverse geopolitical events such as wars, terrorism and tensions between states. It reaches asset prices through several routes. Higher uncertainty and risk aversion raise the risk premium investors demand and cut expected cash flows, so prices fall. Commodity and supply-chain disruptions move inflation and margins. Flight to safety pushes money into safe assets and out of emerging markets. Financial institutions pull back credit and funds face outflows, which amplifies the shock. Policy responses are mostly preparatory. They include stress tests with geopolitical scenarios, adequate capital and liquidity buffers, central bank liquidity backstops, supervision of concentrated exposures, and oversight of fund liquidity. The exam point is that policy prepares the system, and it does not remove the shock.
Formulas
Gordon growth model
V₀ = D₁ ÷ (r − g)
- D₁
- next year's dividend, not the one just paid
- r
- the required return on the equity
- g
- the constant growth rate of the dividend, for ever
A geopolitical shock that raises r and lowers g cuts the value through both channels at once. As g approaches r the value becomes very sensitive.
A practice question
Which description best fits the widely used news-based index of geopolitical risk?
- The share of newspaper articles that discuss adverse geopolitical events such as wars and terrorism. - correct
- The realized volatility of a broad equity index measured over the most recent month of trading.Why not: Confuses a news-based geopolitical measure with a market volatility gauge, which reflects many drivers other than geopolitics.
- The average sovereign CDS spread across all countries with a recent conflict.Why not: Treats a market price as the index; the geopolitical index is built from text, not from credit spreads.
- The annual count of armed conflicts recorded by military agencies.Why not: Uses an event count from conflict databases, which is infrequent and not a news-intensity index.
The Caldara-Iacoviello style index counts the share of newspaper articles about adverse geopolitical events. It is text-based, so it can be measured at high frequency and separated from market prices.
A harder one
A risk manager lists the ways a geopolitical shock moves asset prices. Which is a direct transmission route?
- Central banks in every country are forced to raise policy rates by the same amount, which lowers all valuations mechanically.Why not: Assumes a mechanical, uniform policy reaction; policy responses differ by country and are not an automatic channel.
- Higher uncertainty and risk aversion raise required risk premia while expected cash flows fall, so asset prices decline. - correct
- Investors lower required returns because geopolitical news improves long-term growth visibility.Why not: Reverses the sign: geopolitical risk raises uncertainty and required returns rather than lowering them.
- Equity prices change only if a listed firm's facilities are physically damaged.Why not: Ignores the expectations and risk-premium channel; prices move on perceived risk even without physical damage.
Geopolitical risk lifts the compensation investors require and lowers expected cash flows, and both reduce prices. Other routes include commodity and supply-chain disruptions, flight to safety and tighter credit.
The hardest tier
An equity index is valued by the constant growth model, price = next dividend / (required return - growth). The next dividend is USD 4, the required return is 8% and growth is 3%. A geopolitical shock raises the required return by 1 percentage point and lowers expected growth by 0.5 percentage points. The percentage change in the index is closest to:
- -16.7%Why not: Applies only the higher required return and forgets that growth also falls.
- -23.1% - correct
- -9.1%Why not: Applies only the lower growth rate and ignores the higher risk premium.
- -28.6%Why not: Cuts growth by 1 point instead of 0.5, so the denominator is 7% rather than 6.5%.
Before: 4 / (0.08 - 0.03) = 80. After: 4 / (0.09 - 0.025) = 61.54. Change = 61.54 / 80 - 1 = -23.1%. Both channels, a higher risk premium and lower cash-flow growth, work in the same direction.
