It aims to deliver a multiple, or the opposite, of one day’s move in what it tracks. The multiple resets daily, so over longer periods its return can differ a lot from the multiple of the index return. You buy and sell it through a share-dealing account or platform during stock-market hours, like a share. Its ongoing charge is 0.07% a year — about £7 a year on every £10,000 invested, taken from the fund's value rather than billed to you. Income from its investments is reinvested inside the fund, so it shows up as a rising price rather than cash paid to you. > **Leveraged & inverse:** Built for short-term trading. Because the multiple resets every day, losses can build up quickly when held for longer, even if the index ends up where it started. Latest close: **$121.94** (30/09/2026). ## Key facts | Fact | Value | |---|---| | Ticker (LSE) | IB01 | | ISIN | IE00BGSF1X88 | | Category | Leveraged & inverse | | Type | ETF | | Provider | iShares | | Tracks | ICE US Treasury Short Bond Index | | Income | Accumulating | | Ongoing charge | 0.07% a year (£7 per £10,000) | | Fund size | £12bn | | Launched | 2019 | | Domicile | Ireland | ## Past returns (periods to 30/09/2026) After the fund's ongoing charges.
