Description

iShares iBonds Dec 2027 Term $ Treasury UCITS ETF tracks the issuer-declared index: ICE 2027 Maturity US Treasury UCITS (G27U) Index. The declared annual cost (TER) is 0.10%, plus 0.03% in transaction costs estimated by the issuer in the KID. Replication is optimised physical replication (the KID declares optimisation techniques to achieve a return similar to the index); income is accumulated and reinvested in the fund. The fund has assets of about 18 million euro, was launched on 26 June 2024 and is domiciled in Ireland.

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

The Share Class is a share class of a Fund, which 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 ICE 2027 Maturity US Treasury UCITS Index, the Fund’s benchmark index (Index). The Share Class, via the Fund, is passively managed and aims to invest so far as possible and practicable in the fixed income (FI) securities (such as bonds) that make up the Index. The Index tracks the performance of US Treasury notes and bonds with maturities between 01/01/27 and 02/12/27, inclusive. To be eligible for inclusion in the Index securities must have a fixed coupon schedule and an amount outstanding, excluding amounts held in the Federal Reserve’s SOMA account (the System Open Market Account contains assets acquired through operations in the open market that are used as a store of liquidity by the Federal Reserve Bank.) of at least $1 billion. Inflation-linked debt and strips are excluded from the Index; however, the amounts outstanding of eligible securities are not reduced by any coupon portions that have been stripped. US Treasury bills are not eligible for inclusion in the Index except during the cash reinvestment period in the maturity year. The Index is market capitalisation weighted and rebalances on a monthly basis. Index constituents are market capitalization weighted based on amounts outstanding reduced by amounts held in the Federal Reserve’s SOMA account, times price, plus accrued interest. Market capitalisation is the market value of the outstanding bond issuance. The Fund uses optimising techniques to achieve a similar return to the Index. These may include the strategic selection of certain securities that make up the Index and also the use of financial derivative instruments (FDIs) which may be used for direct investment purposes. The Fund may also engage in short term secured lending of its investments to certain eligible third parties to generate additional income to off-set the costs of the Fund. Recommendation: This Fund is suitable for medium to long term investment, though the Fund may also be suitable for shorter term exposure to the Index. This Fund may not be appropriate for investors who plan to withdraw their money before 02/12/27. Further information about the Fund can be obtained from the latest annual report and half-yearly reports of the iShares V 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.

Keep reading the KID section ▾

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.

Drawdown — distance from previous peak

This isn’t the return: it shows how far the fund is below its previous peak. 0% = you’re at the peak; below zero = how much you’re down and haven’t recovered yet.

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.

Windows longer than the available price history cannot be computed and are not shown: they will appear on their own as time passes. Computed from the daily NAV series, always in nominal terms. Sharpe and Sortino use the ECB main refinancing rate averaged over the period (last year: 2.21%), weighted by days in force, as the risk-free rate. Same formulas as our public methodology: sample standard deviation annualised over 252 days; Sortino with downside deviation. Past performance is not indicative of future results.
