Description

iShares Bloomberg Enhanced Roll Yield Commodity Swap UCITS ETF tracks the issuer-declared index: Bloomberg Enhanced Roll Yield Index. The declared annual cost (TER) is 0.28%, plus 0.14% in transaction costs estimated by the issuer in the KID. Replication is synthetic replication via a swap contract, as the KID declares; income is accumulated and reinvested in the fund. The fund has assets of about 1.6 billion euro, was launched on 28 September 2018 and is domiciled in Ireland.

The fund’s objective — in the issuer’s words

The Fund aims to achieve a return on your investment, through a combination of capital growth and income on the Fund’s assets, which reflects the return of the Bloomberg Enhanced Roll Yield Total Return Index (the Index). The Index measures the return on commodity futures contracts comprised within the Bloomberg Commodity Enhanced Roll Yield Index combined with the notional value of such futures invested at the Secured Overnight Financing Rate (”SOFR”) and aims to mitigate the effects of negative roll yield on the performance of the Index. Roll yield is the difference between the prices of the shorter term and the longer term futures contracts when they are rolled. Further details regarding the Index (including the methodology and its constituents) are available on the index provider’s website at https://www.bloombergindices.com/bloombergcommodity-index-family/. Commodities eligible for inclusion in the Index include: brent crude oil, gasoil, WTI crude oil, heating oil, natural gas, gasoline, gold, silver, copper, zinc, tin, nickel, lead, aluminium, Chicago wheat, Kansas wheat, soybean, soybean oil, soybean meal, corn, cotton, coffee, sugar, live cattle, lean hogs and feeder cattle. The Index is composed of three to four futures contracts for each commodity. The Index rolls to a new set of futures contracts for each commodity on a monthly basis over a period of ten business days seeking to maintain diversified curve exposure over time). The Fund invests in FDIs and will in particular invest in unfunded total return swaps in order to achieve its investment objective. A swap agreement is typically used to achieve a specified return determined by an underlying such as a return on an index. The Fund may invest directly in US Treasury Bills, money market instruments, including instruments issued or guaranteed by governments or public international bodies globally, and deposits with credit institutions. The Fund may also invest into, certificates of deposit, commercial paper and other fixed income securities or money market funds. The Fund intends to replicate the performance of the Index by gaining an indirect exposure, via FDIs, to the individual constituents of the Index. The price of a derivative changes on a daily basis depending on the value of the underlying reference asset(s) which in turn may affect the value of your investment. A change in the value of underlying reference assets can have a greater impact on the value of derivatives than if the assets were held directly since derivatives can be more sensitive to changes in the value of underlying reference assets. The relationship between the return on your investment, how it is impacted and the period for which you hold your investment is considered below (see “How long should I hold it and can I take my money out early?”).

The depositary of the Fund is State Street Custodial Services (Ireland) Limited. Further information about the Fund can be obtained from the latest annual report and half-yearly reports of the iShares VI plc. These documents are available free of charge in English and certain other languages. These can be found, along with other (practical) information, including prices of units, on the iShares website at: www.ishares.com or by calling +49 89427295800 or from your broker or financial adviser.

Your shares will be accumulating shares (i.e. income will be included in their value). Your shares will be denominated in US Dollar, the Fund's base currency. The shares are listed and traded on various stock exchanges. In normal circumstances, only authorised participants may buy and sell shares directly with the Fund. Investors who are not authorised participants (e.g. select financial institutions) can generally only buy or sell the shares on the secondary market (e.g. via a broker on a stock exchange) at the then prevailing market price. The value of the shares are related to the value of the underlying assets of the Fund, less costs (see “What are the costs?” below). The prevailing market price at which the shares trade on the secondary market may deviate from the value of the Shares. Indicative net asset value is published on relevant stock exchanges websites.

Intended retail investor:The Fund is intended for retail investors with the ability to bear losses up to the amount invested in the Fund (see “How long should I hold it and can I take my money out early?”).

Insurance benefits:The Fund does not offer any insurance benefits.

Source: iShares. Issuer-declared historical series; inflation: Eurostat and national statistical institutes, latest available July 2026 — for later days the index stays at the last published value (institutes publish with a few weeks’ lag). The «adjusted for inflation» view expresses value in today’s purchasing power for the selected country; volatility always stays nominal, as elsewhere on the site (deflating it would add artificial swings caused by the monthly cadence of the price index). Past performance is not indicative of future results: these are facts, not a recommendation.

Tracking difference — fund vs index

How much the fund returned above (+) or below (−) its index, year by year. It measures the actual deviation: the combined effect of costs (TER and transaction), securities-lending revenue and replication optimisations — which is why it can beat the TER. Tracking difference was positive in 0 of the last 7 calendar years: a past observation, not an indication of future outperformance.
