Interpretation guide
The FTSE 100: an index priced in sterling and commodities
The FTSE 100 holds the hundred largest companies listed in London. But most of their revenue comes from outside Britain, and energy, mining, and financials dominate the weights — so it responds more to the global commodity cycle and sterling than to the UK economy itself.
A British index that isn't a British indicator
Roughly three-quarters of FTSE 100 revenue is earned abroad. A weaker pound therefore inflates the sterling value of overseas earnings, producing the familiar pattern of currency weakness and index strength moving together.
- FTSE 100 strength during sterling selloffs is structural, not an anomaly.
- The FTSE 250 mid-cap index is the honest read on UK domestic conditions.
- Heavy weights in Shell and BP make oil a primary driver of index direction.
Commodities and dividends
With large miners (Rio Tinto, Glencore) alongside energy, the FTSE 100 effectively tracks the commodity cycle. Its dividend yield is also among the highest of major benchmarks, which draws income buyers when rates fall.
- It tends to hold up better than US indexes when copper and oil are strong.
- The high yield cushions the index's downside in selloffs.
- Its thin technology weight leaves it sidelined during growth themes like the AI rally.
How Korean investors can use it
The FTSE 100 is the mirror image of growth-heavy US indexes, which makes it a useful control group for spotting rotation from growth into value and commodities.
- FTSE 100 strength relative to the Nasdaq is a thermometer for growth-to-value rotation.
- Rising alongside commodities is a supportive backdrop for Korean materials and energy names.
- Cross-check it against Brent and copper to confirm the commodity cycle.
