Description

iShares $ Treasury Bond 0-1yr UCITS ETF tracks the issuer-declared index: ICE U.S. Treasury Short Bond Index (USD). Mind the share class: this is the version hedged to Mexican Peso (MXN) — returns reflect the index plus the effect (and cost) of hedging into that currency. The declared annual cost (TER) is 0.10%, plus 0.02% 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 6.1 billion euro, was launched on 16 May 2019 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 U.S. Treasury Short Bond 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 offers exposure to US government bonds with a remaining maturity (i.e. the time from issue until they become due for repayment) of greater than or equal to one month and less than one year and a minimum amount outstanding of $300 million at the Index rebalance date. The bonds will pay income according to a fixed rate of interest. The Index does not apply a credit rating requirement, but the bonds will have a creditworthiness matching that of the US Treasury. The Fund uses optimising techniques to achieve a similar return to the Index. These techniques may include the strategic selection of certain securities that make up the Index or other securities which provide similar performance to certain constituent securities. These may also include the use of financial derivative instruments (FDIs) (i.e. investments the prices of which are based on one or more underlying assets). FDIs 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.

Keep reading the KID section ▾

The price of fixed income securities may be affected by changing interest rates which in turn may affect the value of your investment. Fixed income securities prices move inversely to interest rates. Therefore, the market value of fixed income securities may decrease as interest rates increase. The credit rating of an issuing entity will generally affect the yield that can be earned on fixed income securities; the better the credit rating the smaller the yield. 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 The Bank of New York Mellon SA/NV, Dublin Branch. Further information about the Fund can be obtained from the latest annual report and half-yearly reports of the iShares 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). The Fund’s base currency is US Dollar. Shares for this Share Class are denominated in Mexican Peso. The performance of your shares may be affected by this currency difference. Your shares will be hedged with the aim of reducing the effect of exchange rate fluctuations between the denominated currency of the shares and the Fund’s underlying portfolio currencies or the Fund’s base currency. FDIs, including FX forward contracts, will be used for currency hedging purposes. The hedging strategy may not completely eliminate currency risk and, therefore, may affect the performance of your shares. Please see the prospectus for further details. 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.

Note — currency risk: the fund is denominated (or hedged) in MXN and the chart is in MXN. For a euro investor, returns also depend on the EUR/MXN exchange rate, up or down.
Currency-hedged share class: our figures are computed on the issuer’s NAV, where the hedge is applied at the daily fixing. Comparison sites using the exchange price may show returns and volatility that differ by 1–2 points: on hedged classes the price-vs-NAV gap is structurally wider and grows with the length of the window. Not a data error — a measurement convention. Details in the methodology.

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.

From month-end NAVs, over the fund’s full history, on the series shown in the chart (dividends reinvested where declared). Deeper colour = larger move.
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.

Rejoined series: the issuer’s historical data contains a unit redenomination (26 July 2021), not retroactively adjusted; we rejoined the earlier history to make it comparable. Returns and risk are computed on the rejoined series.

Tracking difference — fund vs index

We do not publish a tracking difference for this share class — and it is not an oversight.

IB1MXX is hedged to MXN; the index the issuer places next to it in its documents is the unhedged, foreign-currency version. Subtracting one from the other does not measure replication quality: it measures the exchange rate. In a year when the currency moves 5%, “the TD” would come out near 5 points — a plausible-looking number, with decimals, and wrong.

Other sites publish that number. We would rather show one figure less than one figure wrong: the TD will return here the day we have the MXN-hedged index series, which the issuer does not publish today.

Still want to know how well this fund tracks its index? Look at the unhedged sister class, IB01, where fund and index share the same currency: its TD is the right measure of the management, which is the same. Go to the IB01 page →
