Banks and miners make up a large part of the ASX. Knowing what drives each sector before the market opens gives you a cleaner read on the stocks you follow.
The big four banks and major resource companies dominate the ASX 200. Their weight means they often set the tone for the broader market. Even if you do not own them directly, their price action can influence the sentiment around your portfolio.
Australian banks earn a large share of revenue from net interest margin. Changes in the Reserve Bank of Australia cash rate, bond yields and the shape of the yield curve affect profitability expectations.
Lending figures, housing approvals and mortgage growth influence loan book expansion. Slower credit growth can pressure earnings, while stronger data supports the sector.
Keep an eye on unemployment trends and business insolvencies. Rising bad debt provisions can quickly impact bank earnings.
Banks are widely held for income. Dividend forecasts and franking credit levels matter for valuation and sentiment.
Iron ore, copper, gold, lithium and coal prices drive revenue expectations for most ASX mining companies. Overnight moves in these commodities often flow directly into ASX miner prices at the open.
Many commodities are priced in US dollars. A weaker Australian dollar can boost the local value of USD revenue, while a stronger dollar has the opposite effect.
Quarterly production reports, unit cost guidance and shipment updates move individual miners. Watch for guidance changes and operational issues.
China is the largest buyer of many Australian commodities. Data on Chinese property, infrastructure spending and manufacturing activity can influence sentiment across the sector.
