Amundi Euro Government Bond 3-5y vs iShares $ Treasury Bond 7-10yr

They track different indices: Amundi Euro Government Bond 3-5y follows Euro MTS Government Bond 3-5Y and iShares $ Treasury Bond 7-10yr follows ICE US Treasury 7-10 Year. They also differ in cost (0.14% vs 0.07% TER), replication (physical vs physical) and domicile (Francia vs Irlanda).

Nobody can know that: they track different indices, so their returns will diverge, and past index performance is not a prediction. What you can control today is the cost, the tax structure and whether the index actually covers what you want exposure to.

iShares $ Treasury Bond 7-10yr has the lower annual fee. Applying the same 7% gross return to both with €300/month, that fee gap alone is worth about €1,325 after 20 years — that part is arithmetic, not a forecast.

Amundi Euro Government Bond 3-5y is accumulating (dividends are reinvested inside the fund) and iShares $ Treasury Bond 7-10yr is distributing (dividends are paid out to you). For long-term compounding in Spain, accumulating usually defers taxation; distributing gives you income you are taxed on each year.

Yes. Unlike two funds tracking the identical index, these give you genuinely different exposure, so holding both is not automatically redundant — just be aware you may end up overlapping on the largest companies and doubling your rebalancing work.
