FTSE 100: Index Rises 0.06% as Rio Tinto, Anglo American Lead Mining Rally Despite UK Inflation Hitting 2.9%

The FTSE 100 edged 0.06% higher on Wednesday, August 19, 2026, as mining stocks helped support London shares despite fresh inflation concerns. Rio Tinto and Anglo American were among the stronger performers on the index. At the same time, UK inflation rose to 2.9% in July, up from 2.6% in June, with higher energy costs contributing to the increase. Investors are now watching mining stocks, interest rates and the wider UK economy closely.

FTSE 100 Today: Mining Stocks Offset Inflation Pressure

Index Holds Above the Flatline as Miners Rally

The FTSE 100 today is caught between stronger mining shares and renewed concerns about inflation. On August 19, 2026, the index traded around 10,729 in early London trading. It later slipped to 10,711.52 at one point, showing how quickly sentiment shifted during the session.

Mining stocks provided support. Rio Tinto and Anglo American were among the stronger names, while other commodity-linked companies also helped limit the broader decline. The move came after the FTSE 100 had recorded six straight losing sessions before Wednesday.

Banks, meanwhile, came under pressure as investors reassessed expectations for UK interest rates. The result was a clear split between globally exposed commodity companies and businesses that are more closely tied to the domestic economy.

UK Inflation Hits 2.9%: What the July Data Shows

Energy Bills Drive the Inflation Increase

UK inflation was the main economic focus on August 19. The Office for National Statistics reported that CPI inflation rose to 2.9% in July 2026, compared with 2.6% in June. CPIH, which includes owner-occupiers’ housing costs, increased to 3.1% from 2.8%.

Energy costs were one of the main reasons for the increase. Gas prices rose sharply, while the latest energy price-cap change pushed household costs higher. The Ofgem cap increased the typical annual household energy allowance to £1,862, adding to pressure on consumers.

The 2.9% CPI reading is still above the Bank of England’s 2% target. The rise was broadly in line with market expectations, which helped limit the immediate reaction in financial markets.

The bigger issue is whether higher energy costs fade or begin to spread into other areas of the economy. Food inflation has eased, while services inflation remains a more closely watched measure of domestic price pressure.

Why are Rio Tinto and Anglo American Leading the FTSE 100?

Commodity Exposure Supports Mining Shares

Mining companies can benefit when global commodity prices remain firm. Rio Tinto has major exposure to iron ore, aluminium and copper. Anglo American has significant exposure to copper and other industrial commodities.

The mining sector has also shown how quickly investor sentiment can shift. On August 13, weakness among miners helped push the FTSE 100 lower after Antofagasta cut its production outlook.

That makes the latest rebound in mining stocks worth watching, although it does not confirm a lasting recovery. Commodity demand, Chinese industrial activity and supply disruptions will continue to influence the sector.

What Higher Inflation Means for FTSE 100 Investors?

Bank of England Rate Expectations Take Centre Stage

Higher inflation creates a difficult backdrop for UK equities. If price pressures remain high, interest rates could stay elevated for longer. That would raise borrowing costs and put pressure on companies that are more sensitive to rates.

The FTSE 100 is different from many domestic-focused indexes because many of its largest companies earn revenue outside the UK. That international exposure helps explain why commodity-heavy companies can perform well even when UK economic data is weaker.

Investors should look at inflation alongside global commodity prices rather than treating the latest CPI reading as a direct signal for the entire FTSE 100.

Rio Tinto and Anglo American: What Does Meyka Say?

Meyka’s available Rio Tinto model gives a bearish overall outlook. Its model projects a one-month price of $92.04 for RIO and a one-year price of $86.53. These figures are model-based estimates and are not guaranteed price targets.

For Anglo American, Meyka’s technical analysis points to stronger momentum but also warns of overbought conditions. Its listed RSI is 69.48, while the stock is close to the upper Bollinger Band. That combination can leave the shares exposed to a short-term pullback.

Meyka’s analysis gives Anglo American a B grade in its tracked coverage. Deutsche Bank maintained a Buy rating in February and raised its target to 3,600 GBp. Barclays later maintained an heigherweight rating and lifted its target to 3,850 GBp.

An AI stock analysis tool can help investors compare these signals, but model forecasts should not replace fundamental research.

FTSE 100 Outlook: Can Miners Keep Supporting the Index?

The immediate direction of the FTSE 100 will depend on commodity prices, UK rate expectations and global risk sentiment.

If copper and other metals remain supported, mining stocks could continue to cushion the index. A slowdown in global demand or fresh production problems could change that quickly.

For now, the FTSE 100 is balancing strong commodity exposure against a tougher UK inflation backdrop. Investors should watch the 10,700 area and mining-sector price action for signs of where the index could move next.

Conclusion

The FTSE 100’s latest move reflects the mixed signals facing UK investors. Mining stocks such as Rio Tinto and Anglo American are providing support, while inflation at 2.9% keeps pressure on interest-rate expectations. Commodity prices, energy costs and Bank of England policy will remain important in the days ahead. A sustained mining rally could support the index, but weaker global demand could quickly change the picture.
