What is IBTM?

IBTM is iShares $ Treasury Bond 7-10yr UCITS ETF, the European-listed product BestFolio uses when translating IEF. Most targets are UCITS ETFs; some commodity and leveraged targets are UCITS-eligible ETCs or ETPs instead. Product structure and retail eligibility must be checked for the exact ISIN.

Same 7-10 year US Treasury exposure. The source ticker has 1x exposure and the mapped target has 1x exposure, so BestFolio can flag leverage differences during allocation translation.
