Weekend developments in the Middle East war are expected to have a significant market impact this coming week. The key updates are summarised below.

Investors’ willingness to accept risk over a given period is commonly described in financial markets as “risk-on” or “risk off”. Optimism about the outlook characterises a “risk-on” market, encouraging investors to purchase riskier assets. Concern about the future produces a “risk-off” market: investors prefer to ‘play it safe’ by choosing lower-risk assets with more dependable potential returns, even when those returns are relatively modest.
A favourable growth outlook generally supports equities and most commodities, apart from gold, during “risk-on” periods. Stronger demand also lifts the currencies of major commodity-exporting countries, while cryptocurrencies advance. By contrast, a “risk-off” environment favours bonds, particularly major government bonds, alongside gold. Safe-haven currencies, including the Japanese yen, Swiss franc and US dollar, also benefit.
Commodity-export dependence helps explain why the Australian dollar (AUD), Canadian dollar (CAD), New Zealand dollar (NZD) and minor currencies such as the ruble (RUB) and South African rand (ZAR) typically strengthen in “risk-on” markets. Growth in their economies relies heavily on commodity exports. As investors anticipate stronger economic activity and greater future demand for raw materials, commodity prices tend to increase, supporting these currencies.
During “risk-off” periods, the US dollar (USD), Japanese yen (JPY) and Swiss franc (CHF) are the major currencies that typically appreciate. The dollar benefits from its status as the world’s reserve currency and from crisis-driven purchases of US government debt. Investors regard that debt as safe because the world’s largest economy is considered unlikely to default. Demand for Japanese government bonds supports the yen: domestic investors hold a large share of these bonds and are unlikely to sell them off, even during a crisis. For the Swiss franc, support comes from strict Swiss banking laws that provide investors with greater capital protection.
