FTSE 100 Today

The FTSE 100 (Financial Times Stock Exchange 100 Index, commonly called the "Footsie") tracks the 100 companies with the highest market capitalization listed on the London Stock Exchange (LSE). Launched on January 3, 1984 at a base level of 1,000, it is the UK's primary equity benchmark and one of the most recognized indices globally.

The FTSE 100 is maintained by FTSE Russell (a subsidiary of London Stock Exchange Group) and rebalanced quarterly. To qualify, companies must have their primary listing on the LSE and meet minimum liquidity requirements. The index is market-capitalization weighted — Shell, AstraZeneca, HSBC, and Unilever are typically the largest components.

A critical characteristic: approximately 70–75% of FTSE 100 revenues are earned outside the UK. These are global multinationals that happen to list in London. This means the FTSE 100 is more a measure of global blue-chip corporate health than the UK domestic economy. For UK economic health, the FTSE 250 (mid-cap, more domestically focused) is a better gauge.

The FTSE 100 has a well-known negative correlation with GBP that surprises many traders. Here's why:

• Revenue currency mismatch: FTSE 100 companies earn ~70% of revenues in USD, EUR, and other currencies. Shell earns in USD, Unilever earns globally, Rio Tinto earns in AUD and USD. When GBP weakens against USD and EUR, these overseas revenues translate into more pounds — boosting reported earnings and the stock prices.
• Practical trading example: Brexit vote (June 2016) — GBP crashed 10% overnight. The FTSE 100 initially fell with the shock but then surged to new highs within days, because a weaker pound inflated the sterling value of overseas earnings.
• For GCC investors: If you hold FTSE 100 exposure and GBP strengthens, your FTSE 100 investment in GBP terms may lag — but your currency gain compensates. Hedging FTSE 100 with a long GBP position is counterproductive for income-focused investors.

Shell and BP together represent roughly 10–12% of the FTSE 100 by market capitalization. Add in smaller oil services companies and the index has significant direct oil exposure. This makes the FTSE 100 unusual among major equity indices — it behaves more like a commodity index in oil bull markets:

• When Brent crude rises from $70 to $100/barrel, Shell and BP earnings improve dramatically (both produce millions of barrels per day). This lifts the FTSE 100.
• FTSE 100 performed relatively well in 2022 (−2% vs S&P 500 −20%) partly because surging energy prices boosted Shell and BP while hurting tech-heavy US indices.
• GCC investors who already have oil price exposure (through government jobs, business, real estate) should consider that FTSE 100 adds to their oil correlation — not diversifies away from it.

The UK is a top investment destination for GCC wealth. Qatar Investment Authority (QIA) holds significant London real estate and Barclays Bank stakes. UAE sovereign wealth funds hold UK equities and infrastructure. Saudi HNWIs maintain London property portfolios. The FTSE 100 level and GBP/USD rate are therefore directly relevant to the value of these holdings in local currency terms.

AED/GBP: Since AED is pegged to USD, the AED/GBP cross moves entirely with GBP/USD. When GBP falls (e.g., post-Brexit, UK political crises), UAE investors' UK property and equity values decline in AED terms — even if FTSE 100 rises in GBP terms.
