Why "just buy an index fund" does not work when you live abroad
Index funds are good investment vehicles. For expats, the question is not which index to track. It is which legal wrapper holds the funds, where it is domiciled, and what happens to the portfolio when you change tax residency or die in a jurisdiction that has no obligation to your heirs. Structure first. Funds second.
Review My Investment StructureFour structural problems most expat portfolios have
The first is domicile. An expat holding US-domiciled ETFs is holding US-sited assets. Under US tax law, non-US persons holding US-sited assets above $60,000 at death are subject to federal estate tax at up to 40% on the excess. This is the default legal position. No treaty between the UK, France, Germany, or Malaysia with the United States changes this for individuals who are not US citizens or green card holders.
The second is currency. An expat who earns in USD, spends in MYR, holds investments in GBP, and plans to retire in EUR has four currency exposures running simultaneously. If none of them have been actively considered, the portfolio is making implicit currency bets that were never part of a coherent plan.
The third is estate planning. A global portfolio spread across UK, German, Malaysian, and Singapore accounts has different inheritance rules in each jurisdiction. In Malaysia, there is no automatic spousal exemption equivalent to the UK nil-rate band transfer. In some European jurisdictions, forced heirship rules require specific portions of the estate to pass to children regardless of the will. An investment structure built without considering these is a problem deferred, not avoided.
The fourth is reporting. Some investment wrappers, particularly offshore bonds and certain US-regulated accounts, create reporting obligations in the country of residence. Failing to report a foreign account to LHDN (Malaysia) or IRAS (Singapore) is a compliance failure that creates penalties regardless of whether any tax is actually owed.
Irish-domiciled accumulating UCITS: the default for globally mobile investors
UCITS (Undertakings for Collective Investment in Transferable Securities) is the European fund regulatory framework. Irish-domiciled UCITS funds are the most widely used investment vehicle for non-US global investors, and for good reason: they are regulated under EU law, domiciled in a country with one of the world's most comprehensive tax treaty networks, and structurally incompatible with US estate tax because they are not US-sited assets.
Accumulating share classes reinvest dividends automatically rather than distributing them. For an expat in a country with a territorial tax system, this matters: distributed dividends may constitute foreign income received in the country of residence, triggering a local tax event. Accumulating funds defer this. For an expat in Malaysia under the current FSI framework, accumulating funds held offshore and not remitted avoid the remittance event entirely until a deliberate withdrawal decision is made.
The fund universe is deep enough to build a genuinely diversified global portfolio without leaving the UCITS wrapper. The table below shows the core building blocks used in a standard expat portfolio structure.
| Ticker | Fund | Exposure | OCF |
|---|---|---|---|
| IWDA | iShares Core MSCI World UCITS ETF | Developed markets global equity | 0.20% |
| VWRA | Vanguard FTSE All-World UCITS ETF | Global equity incl. EM | 0.22% |
| EIMI | iShares Core MSCI EM IMI UCITS ETF | Emerging markets equity | 0.18% |
| AGGH | iShares Core Global Aggregate Bond UCITS ETF | Global investment grade bonds | 0.10% |

Three structures that cost expats more than they should
High cost, low flexibility for most expats
Offshore portfolio bonds (Luxembourg or Isle of Man domiciled) are often sold to expats as tax-efficient wrappers. The wrapper has legitimate uses in specific situations. The problem is the fee structure: typically 1 to 2% annual platform charge plus adviser trail commission of 0.5 to 1%, often in addition to an upfront commission of 3 to 7% on the invested amount.
For most expats, direct UCITS holdings in a low-cost brokerage account (Interactive Brokers, Saxo, Charles Schwab International) achieve the same structural outcome at a fraction of the cost. See the detailed comparison on the offshore bonds explainer page.
40% estate tax exposure for a marginal performance difference
US ETFs are excellent vehicles for US persons. For non-US persons, they create an estate tax exposure that eliminates much of the fee advantage they appear to offer. SPY has a lower OCF than IWDA. The potential 40% estate tax on the full value above $60,000 at death is not a fee. It is a structural risk that no OCF advantage can compensate for over a lifetime.
Additionally, US-domiciled ETFs pay dividends subject to 30% US withholding tax for non-US holders (rather than 15% via Ireland's treaty). On a dividend-heavy portfolio, this compounds significantly over 20 to 30 years.
What the fee structure reveals about the incentive
Products that pay advisers upfront commissions of 3 to 7% exist because the incentive for the adviser is to complete the transaction, not to optimise the long-term outcome. Regular premium savings plans, endowment-style products, and certain structured products sold to expats in Southeast Asia carry implicit or explicit commissions that are paid from the client's invested capital over the policy term.
The correct question when evaluating any investment product is: what does the adviser earn from recommending this, and does that incentive align with my outcome? Bratu Capital's fee model is 2% upfront on new investments and 1% annual AUM. No trail commissions. No product-linked incentives. The model is stated, not hidden.
How a structurally sound expat portfolio is actually built
The starting point is not fund selection. It is the brokerage account. For most expats in Southeast Asia, the most practical custody arrangement is an account with a broker that accepts non-resident clients, operates under a stable regulatory framework, charges low transaction costs, and allows access to the full range of London Stock Exchange-listed UCITS ETFs. Interactive Brokers and Saxo Bank are the most commonly used platforms for this profile.
Once the custody structure is in place, asset allocation follows the standard framework for a long-horizon, globally mobile investor: equities as the growth engine (IWDA or VWRA providing developed and emerging market exposure), bonds as the stabiliser (AGGH or a regional equivalent), and sufficient cash or short-duration instruments to cover 12 to 24 months of planned expenditure without requiring equity liquidation in a market downturn.
Currency allocation is built into the asset allocation decision. A European expat planning to retire in euros, currently spending in Malaysian ringgit, and earning in USD, should hold their long-term savings primarily in EUR or in globally diversified positions that include significant EUR-denominated exposure. The currency overlay is not a separate trading strategy. It is a natural consequence of thinking about where the money will actually be spent.
Rebalancing is done annually or when a significant market move takes the allocation meaningfully off target, defined as more than 5 percentage points deviation from target in any major asset class. Rebalancing inside a tax-free or tax-deferred account (SIPP, QROPS) should happen there first to avoid triggering taxable events in the open brokerage account.
The structure is reviewed when circumstances change: a new tax residency, a change in employment, a pension decision point, an inheritance, or a material change in planned retirement timeline or location. Outside these events, the structure requires maintenance, not active management.
Review the structure underneath your current investments
Most expat investment accounts were opened for convenience, not structural correctness. A 30-minute review identifies the domicile issues, the currency mismatches, and the fee drag in the current setup before they compound further.
