In a traditional bond ladder, you buy bonds maturing in, say, 2026, 2028, 2030, and 2032. As each matures, you reinvest the cash into the longest rung, rolling the ladder forward. The goals are predictable cash flow, automatic reinvestment, and lower sensitivity to any single interest rate move compared to holding a long-duration fund outright.

With ETFs, you replicate this by holding a set of maturity-band ETFs — for example, a 0-1yr ETF, a 1-3yr ETF, a 3-7yr ETF, and a 7-10yr ETF. Each fund rolls its holdings internally, so the portfolio never literally matures. You achieve similar duration control through periodic rebalancing rather than bond-by-bond redemption.

For European investors there are two practical structures available in UCITS: maturity-band ETFs (perpetually rolling, no end date) and target-maturity ETFs (iShares iBonds, which liquidate at a set year like an actual bond). Both are covered below.

Eurozone government bond minimum denominations are typically EUR 1,000 per bond, but retail-market liquidity is thin and bid-ask spreads at small sizes are wide. Investment-grade corporate bonds commonly require EUR 100,000 minimum per line. Building a properly diversified individual ladder with 10-20 positions across issuers and maturities is impractical for most retail portfolios. Bond ETFs remove all of these friction points:

The trade-off is that standard maturity-band ETFs never actually mature — they roll continuously. If you need a specific cash amount at a specific date (a mortgage lump sum in 2028, for example), the iShares iBonds UCITS range is a closer match to the intent of a traditional ladder.

A simple starting allocation for a moderate investor: 30% / 30% / 25% / 15% across rungs 1-4. This produces a weighted average portfolio duration of roughly 3.5-4 years — meaningfully lower than a broad EUR aggregate index fund, which typically runs 6-8 years.

Rebalancing cadence: once a year, or whenever any rung drifts more than 5 percentage points from target weight. For a 4-rung ladder that typically means 2-4 trades per rebalance — low cost at any broker charging under EUR 5 per trade.

Each iBonds UCITS ETF holds EUR investment-grade corporate bonds maturing in the target year. From purchase until December of that year, the fund collects coupon income and reinvests maturing bond proceeds into cash. At year-end the ETF liquidates and investors receive NAV. The yield displayed at purchase is therefore a close approximation of the yield you will realise if you hold to the end date — the same logic as a bond’s yield-to-maturity figure.

Because iBonds ETFs are distributing, European investors in countries that tax distributions differently from capital gains — Germany, France, the Netherlands — should factor this into their decision before choosing iBonds over accumulating maturity-band ETFs. See the UCITS ETF tax by country guide for country-specific treatment and the acc vs dist explainer for the underlying mechanics.

For EUR-denominated Eurozone government bond ETFs — the simplest core of any EU investor’s ladder — withholding tax is generally not a concern. Eurozone governments do not withhold at source on bond coupon payments, so the domicile of an Ireland-domiciled ETF holding German or French bonds creates minimal tax complexity.

Complexity rises sharply if you add USD-denominated ETFs (e.g. USD Treasury ETFs hedged to EUR). The US imposes a 30% withholding rate on interest income. An Ireland-domiciled ETF holding US Treasuries benefits from the US-Ireland tax treaty (reduced to 0% for qualifying funds under Article 11), but the specific structure matters.

Interactive Brokers (IBKR) is the strongest overall option for a UCITS bond ladder. The platform lists virtually every maturity-band and iBonds ETF across Xetra, Euronext Amsterdam, and the London Stock Exchange. The tiered commission structure starts from approximately EUR 0.05% per trade (minimum EUR 1.25), making annual rebalancing across 4 rungs very low cost. Limit order execution quality is excellent, and IBKR pays meaningful interest on EUR cash held between rebalances. Open at Interactive Brokers →

DEGIRO offers wide UCITS ETF coverage and flat transaction fees of EUR 3-5 depending on exchange. For a ladder rebalanced once a year, total annual rebalancing cost runs EUR 12-20 — reasonable for portfolios above EUR 15,000. The ETF Core Selection includes some popular bond ETFs at zero transaction cost for one monthly trade. Open at DEGIRO →

Trade Republic charges EUR 1 per trade and supports savings plans with fractional ETF orders. For smaller investors under EUR 15,000 building a bond ladder incrementally through monthly contributions, Trade Republic is the most practical entry point. The ETF catalogue covers the core iShares maturity-band government bond ETFs and a selection of iBonds. Note that Trade Republic’s universe is smaller than IBKR’s — verify each ETF is listed before committing to this structure. Open at Trade Republic →
