iShares Core FTSE 100 ETF: May 2025 update

• BlackRock has been managing index portfolios since 1971

• This ETF provides exposure to the largest 100 companies in the UK

• The ETF’s low charges should help it track the FTSE 100 Index closely

How it fits in a portfolio

An ETF is a basket of investments that often includes shares or bonds. They tend to track the performance of an index such as the FTSE 100 and trade on stock exchanges, like shares. This means their price fluctuates throughout the day.

The iShares Core FTSE 100 ETF invests in the 100 largest companies in the UK. While the FTSE 100 is a UK index, many of the companies also earn money overseas. Investors will therefore be indirectly investing into foreign economies as well as the UK.

An ETF is one of the simplest ways to invest and can be a low-cost starting point for an investment portfolio aiming to deliver long-term growth. This ETF could be used to diversify a global portfolio, or one focused on smaller companies or other investments such as bonds.

Manager

Dharma Laloobhai is Co-Head of BlackRock’s EMEA Index Equity International Portfolio Management team. She’s responsible for fund managers based in London who manage developed and emerging market iShares equity index funds and ETFs.

While Laloobhai leads the team, each ETF at BlackRock has a primary and secondary manager, though in practice a broader team helps to manage each ETF. The wider team is well-resourced and experienced in index investing.

Process

This ETF aims to track the performance of the UK’s largest 100 companies, as measured by the FTSE 100 Index. It does this by investing in every company, and in proportion with each company’s weight in the index. This is known as full replication and should help the ETF track the index closely.

Financial companies make up the largest part of the ETFs assets, accounting for 23.72% at the end of March 2025. Consumer staples and industrial businesses followed at 15.87% and 14.84% respectively.

In any ETF, taxes, dealing commissions and the cost of running the ETF all drag on performance. BlackRock use a system to help them determine the most efficient way to trade. They also cross trade internally across all their index funds and ETFs when there is an index rebalance. This helps to reduce costs.

The ETF can lend some of its investments to others in exchange for a fee in a process known as stock lending. This offsets some of the costs involved with running the ETF. Since BlackRock’s lending program started in 1981, only three borrowers with active loans have defaulted. In each case, BlackRock was able to repurchase every security out on loan with collateral on hand and without any losses to their clients. Even so, stock lending adds risk.

As this ETF is listed offshore investors are not usually entitled to compensation from the UK Financial Services Compensation Scheme.

Culture

BlackRock is currently the largest asset manager in the world, running around $11.6trn of assets globally as of March 2025. The company was founded by eight partners including current CEO Larry Fink and is known for both active and passive strategies. Employees at BlackRock are encouraged to hold shares in the company so that they are engaged with helping the company perform well and grow. The iShares brand represents BlackRock's family of index tracking and exchange-traded funds.

As the world's largest asset manager, and with lots of resource and knowledge under its belt, BlackRock benefits from unique access to the marketplace, which can help reduce trading costs. BlackRock is also a pioneer in the passive investment space and has a track record of innovation in this part of the investment market.

The team running this ETF also works closely with various equity and risk departments across the business. We believe this adds good support and challenge on how to run the ETF effectively.

ESG Integration

BlackRock was an early signatory to the Principles for Responsible Investment (PRI) and has offered Environmental, Social and Governance (ESG)-focused funds for several years, including through its iShares range of passive products. However, it only made a company-wide commitment to ESG in January 2020. Following that announcement, the company promised to expand its range of ESG-focused ETFs, screen some thermal coal companies out from its actively managed funds and require all fund managers to consider ESG risks.

BlackRock’s Investment Stewardship Team aims to vote at 100% of meetings where it has the authority to do so. The Investment Stewardship team engages with companies, in conjunction with fund managers, and the results of proxy votes can be found on the BlackRock website’s ‘proxy voting search’ function.

BlackRock has courted controversy in recent years for failing to put its significant weight behind shareholder resolutions aimed at tackling climate change. It responded by committing to be more transparent on its voting activity and providing rationales for key votes.

BlackRock raised further concerns in 2022 when it indicated it might support fewer shareholder proposals based on environmental and social issues in the future. However, its support for shareholder resolutions has fallen dramatically, from 40% in 2021 to just 4% in 2024. BlackRock argues that many of the resolutions were overreaching, lacked economic merit or didn’t promote long-term shareholder value, but this reasoning has been met with some scepticism.

In 2024, Blackrock announced that its US arm would step back from the Climate Action 100+ collective engagement initiative, citing legal considerations, although it suggested its international arm would remain a member.

The iShares Core FTSE 100 ETF tracks an index that does not specifically integrate ESG considerations into its process. The ETF can therefore invest in shares issued by companies in any sector, in line with the index.

Cost

The ETF currently has an ongoing annual fund charge of 0.07%. Ensuring an ETF has a low charge is an important part of tracking the underlying index closely. The annual charge to hold ETFs in the HL ISA or SIPP is 0.45% (capped at £45 p.a. in the ISA and £200 in the SIPP). There are no charges from HL to hold ETFs within the HL Fund and Share Account or HL Junior ISA.

As ETFs trade like shares, both a buy and sell instruction will be subject to the HL share dealing charges.

Performance

The ETF has tracked the FTSE 100 Index closely over the long term. In the last 10 years, the ETF has returned 77.35%* compared to the benchmark’s return of 79.26%. As expected of ETFs, it’s fallen behind the index over the long term because of the costs involved. However, the management tools used by the team have helped to reduce the tracking difference between the ETF and the index.

Over the past 12 months, the ETF has gained 8.03% versus 8.21% for the benchmark. Remember, past performance isn’t a guide to future returns.

With inflation closer to target, the Bank of England (BoE) lowered interest rates in August 2024 after holding rates at a 16 year high for a full year. Although inflation has risen since then, partly because of the tax increases announced in the Autumn budget. The BoE has continued to cut interest rates but has taken a gradual approach and rates could therefore stay higher, and for longer, than initially expected.

The financials sector contributed significantly to the ETF’s overall returns over the year as higher interest rates have been a tailwind for banks who profit from the increased cost of borrowing. Companies in the consumer staples sector also performed well.

Whereas the energy sector was a big detractor from performance as the profits of large UK energy companies, like Shell and BP, have fallen because of lower energy prices. The basic materials sector also contributed negatively to performance due to a weak period for commodity markets.

The UK stock market didn’t perform as well as other global markets, like the US and China, in 2024. However, this has since reversed, and European markets including the UK, have performed better than most other major markets so far in 2025. This is due to concerns over growth and inflation in the US, the potential impact of Trump’s proposed tariffs on Asian countries and expectations for increased defence spending in Europe.

Given BlackRock's size, experience and expertise running ETFs, we expect this ETF to continue to track the FTSE 100 Index well in future, though there are no guarantees.
