VWCE and IWDA are popular ETFs among index investors. The two funds are similar in that they're both highly diversified index funds. But they do have differences that can be important long-term.
We show how you can determine which is better suited for you. We then compare VWCE to a combination of IWDA and EMIM. EMIM is an ETF that addresses IWDA's main shortcoming in terms of diversification. Finally, we put VWCE side-by-side with the Curvo Growth portfolio. We end by showing why Curvo is a great way to invest in index funds. After all, we built Curvo to solve the difficulties of managing your own investments through a broker.
What is VWCE?
The VWCE ETF (ISIN: IE00BK5BQT80) is popular in the index investing community. The fund was launched by Vanguard in 2019 and currently holds more than €5 billion under management. Vanguard is one of the largest asset managers in the world, and its founder Jack Bogle is often credited as the inventor of the index fund.
VWCE tracks the FTSE All-World index, a combination of the FTSE Developed Markets index and the FTSE Emerging Markets index. The index consists of over 4,000 stocks. Because it's so diversified, investors can find in VWCE a great way to follow the global stock market by holding a significant portion of the world's stocks. Companies such as Apple, Microsoft, Amazon, etc… are represented in the index. The FTSE All-World index has delivered an average of 8.9% per year since 2005.
What is IWDA?
IWDA is an ETF that tracks the MSCI World index, an index composed of about 1,500 stocks from 23 countries that economists qualify as "developed": United States, Germany, Japan… The fund is offered by iShares, a brand of BlackRock. BlackRock is an immense asset manager, just like Vanguard, with over $2 trillion invested.
The returns of IWDA have also been excellent throughout the years. Since 1979, the MSCI World index has delivered an average return of 10.9%! If you had invested €10,000 in 1979, you would have had around €900,000 today.
VWCE vs IWDA
We compare VWCE to IWDA based on several criteria:
- cost of the funds
- broker fees
- suited for monthly investing
- size of the funds
- governance of the fund provider
The graph above shows that the historical performance of VWCE and IWDA has been close to equal. Both have yielded an average yearly return of around 8.8%, which is considerable especially compared to a savings account! The large overlap of the stocks and their weights in the FTSE All-World and MSCI World indices explains the similarity.
Diversification: VWCE wins
VWCE is more diversified. The underlying index, the FTSE All-World index, consists of over 4,000 stocks, while the MSCI World index is composed of "only" 1,500 stocks. The inclusion of emerging markets in the FTSE All-World index explains the difference. The MSCI World index includes only stocks from "developed" markets (United States, Germany, Japan...).
We saw that the past performances of VWCE and IWDA do not differ much. Emerging markets represent a relatively small part of the total stock market, so including them has little effect on the overall price. However, it's a good idea to diversify more when you get the chance. The weight of emerging markets may increase in the future, and you will benefit from this growth when investing in VWCE.
Cost of the funds: IWDA wins (slightly)
The cost of an ETF is measured by the total expense ratio, often abbreviated as "TER". It's the fee that the fund provider charges for managing the fund, and it's expressed as a yearly percentage on the amount you invest. At 0.20%, the TER of IWDA is slightly cheaper than that of VWCE, which is 0.22%.
Taxes: IWDA wins
Taxes are an important consideration when choosing an ETF. Both VWCE and IWDA fulfil some fiscal best practices, particularly for Belgians:
- ✅ They're both accumulating, meaning that neither requires you to pay dividend taxes. Instead, dividends are automatically reinvested in the fund.
- ✅ They're both domiciled in Ireland. We prefer funds domiciled in Ireland or Luxembourg because they're slightly more optimised fiscally, as these two countries have special tax treaties with the US.
- ✅ They both invest only in stocks. So no Reynders tax has to be paid, which is the Belgian tax on capital gains for bonds. Fortunately, in Belgium there's no tax on capital gains for stocks!
However, IWDA has an advantage when it comes to the Belgian transaction tax. Because VWCE is registered in Belgium, some brokers charge a 1.32% tax rate when buying and selling the ETF. But the transaction tax for IWDA is always 0.12%, which is significantly lower.
Broker fees: IWDA wins
But for IWDA, the fees for the other brokers tend to be lower. That's because the ETF also trades on Euronext Amsterdam. Many Belgian brokers as well as foreign brokers active in Belgium, have cheaper fees for Euronext exchanges. VWCE trades only in Germany and Italy, resulting in slightly higher fees for us.
Both VWCE and IWDA are physically replicated, which is the safest as it means the fund providers hold the actual stocks in the index. This is unlike synthetic replication, where the performance of the index is replicated through financial engineering.
Suited for monthly investing: IWDA wins
Investing part of your income every month is the best strategy for most people. It simplifies saving and budgeting because your investments follow the rhythm of your income. It also removes the temptation of timing the market. Market timing is incredibly difficult and most often leads to a worse outcome. On top that, it can bring negative emotions such as stress or regret. In contrast, monthly investing brings peace of mind.
IWDA trades around €60 whereas VWCE trades around €90. Most brokers do not offer fractional shares, meaning you have to buy whole units of a share. The lower stock price makes IWDA easier for monthly investing, as you will have less cash on your brokerage account not working for you.
Size of the funds: tie
Over €40 billion is invested in IWDA, and VWCE has €5 billion invested. That's a large difference. But both funds are sufficiently large that the risk of either shutting down by their provider is minimal.
Neither IWDA or VWCE exclude companies based on sustainability criteria. Fossil fuel industry, weapon industry, companies that do not meet certain standards for labour rights... it's all in there.
Governance of the fund provider: VWCE wins
Vanguard has a unique structure because the company is owned by its funds, which in turn are held by the shareholders of the fund. So by purchasing shares of VWCE, one of Vanguard's funds, you effectively become part owner of Vanguard. This organisation ensures that the goals of Vanguard are aligned with its investors, and it has allowed the company to constantly lower their fees as economies of scale were passed on to investors.
BlackRock has a more traditional governance, where the shareholders of BlackRock are not necessarily the investors in their funds.
Verdict: it mostly depends on your broker
Costs and taxation aside, VWCE is slightly better because of the greater diversification. But depending on your broker, you may pay higher fees and Belgian transaction tax when investing in VWCE than IWDA. In that case, IWDA can be a better trade-off.
VWCE vs IWDA + EMIM
EMIM is an ETF that tracks the MSCI Emerging Markets IMI index. By combining IWDA with EMIM, you make up for IWDA's shortcoming of investing only in developed markets by adding stocks from emerging markets into the mix. EMIM is offered by BlackRock, the same provider as IWDA.
The market capitalisation of emerging markets is about 12% of the global stock market. So in the following comparison,, we assume that our IWDA + EMIM portfolio is composed of 88% IWDA and 12% EMIM.
The performance of VWCE and IWDA + EMIM has been very similar in the past. Since 2005, IWDA + EMIM has returned an average 8.8% per year, and 8.7% for VWCE. This difference is not significant enough.
Diversification: IWDA + EMIM wins
With the addition of EMIM, the combination of IWDA and EMIM contains 4,500 stocks. This is slightly more diversified than VWCE, mainly because the MSCI Emerging Markets IMI also contains small companies from emerging markets, whereas VWCE focuses on medium-sized and large companies.
Cost of the funds: IWDA + EMIM wins
The total expense ratio of EMIM is 0.18%. With a 88/12 split, this means that IWDA + EMIM has a combined TER of slightly less than 0.20%. This is lower than VWCE, with a TER of 0.22%.
Taxes: IWDA + EMIM wins
EMIM checks all the important tax considerations we saw above: it's accumulating, domiciled in Ireland, and fully invested in stocks. The Belgian transaction tax of EMIM is 0.12%, just like it is for IWDA. We saw earlier that some brokers charge a 1.32% tax rate for VWCE. So IWDA + EMIM is better than VWCE in terms of taxes.
Broker fees: VWCE wins
EMIM is free on DEGIRO and BUX Zero. Unless you use either of these brokers, you are going to pay broker fees for every purchase and sale. And a single ETF is almost always going to be cheaper than two ETFs, as brokers charge per transaction. So when it comes to broker fees, VWCE is a better option than IWDA + EMIM.
VWCE, IWDA and EMIM are all physically replicated, which is preferred over synthetic replication.
Suited for monthly investing: VWCE wins
Investing monthly means you pay broker fees every month. VWCE is better for monthly investments than IWDA + EMIM because buying a single fund is almost always going to be cheaper than buying two.
Size of the funds: tie
The size of EMIM is €13 billion, so the risk of BlackRock closing the fund is minimal.
The MSCI Emerging Markets IMI index does not exclude companies based on sustainability considerations. All the companies that are bad for the planet and society are present in VWCE, IWDA and EMIM: the weapon industry, fossil fuels, gambling, etc...
Verdict: VWCE is preferred in most cases
A single-fund portfolio has a few advantages compared to a portfolio of several funds IWDA + EMIM. For one, it reduces broker fees. Secondly, a single fund is easier to manage because you don't need to worry about rebalancing. You need to periodically rebalance the IWDA + EMIM portfolio to maintain the 88/12 split.
However, the broker fees and Belgian transaction tax can be expensive for VWCE, especially if you invest monthly. In that case, the IWDA + EMIM combination may end up being cheaper. We refer you to our broker comparison tool to make the calculations!
VWCE vs Curvo Growth
A last option the Curvo Growth portfolio. It consists of two funds:
- 80% of the portfolio is allocated to Vanguard ESG Developed World All Cap Equity (ISIN: IE00B5456744), which tracks the FTSE Developed All Cap Choice index.
- 20% of the portfolio is allocated to Vanguard ESG Emerging Markets All Cap Equity (ISIN: IE00BKV0W243), which tracks the FTSE Emerging Market All Cap Choice index. 80% of the portfolio is allocated to the fund.
Both funds are offered by Vanguard, the same provider as VWCE.
Let us compare VWCE to Curvo Growth.
Looking at the historical performance of VWCE and Curvo Growth, we can see that they are very similar. Both have delivered an average yearly return of around 8.8% since 2005.
Diversification: Curvo Growth wins
The total number of stocks in the Curvo Growth portfolio is 9,513. This is more than double the amount of companies in VWCE, so Curvo Growth is more diversified than VWCE. The reason is that the indices in Curvo Growth also contain small companies, whereas VWCE focuses just on medium-sized and large companies.
Cost of the funds: VWCE wins
The combined total expense ratio of the Curvo Growth portfolio is 0.21%, which is slightly lower than VWCE's 0.22%. But Curvo also comes with a 1% management fee, because it's an investment app that offers many benefits compared to a broker. We explain these below.
Taxes: Curvo Growth wins
The funds in the Curvo Growth portfolio aren't liable for the Belgian transaction tax. This is an advantage compared to VWCE, whose tax rate is 1.32% for many brokers.
Broker fees: Curvo Growth wins
There are no broker fees when investing in the Curvo Growth portfolio. The reason is that the funds in Curvo Growth aren't ETFs but index funds.
ETFs and index funds essentially the same in that both track an index. The main difference is that ETFs are traded on a stock exchange whereas index funds are purchased directly from the fund provider (which is Vanguard for the funds in Curvo Growth). Because no broker is needed to buy the funds in Curvo Growth, there are no broker fees!
Both funds in Curvo Growth are physically replicated, like VWCE. This is preferred over synthetic replication.
Suited for monthly investing: Curvo Growth wins
Monthly investing is a winning strategy for most people, and Curvo is particularly well-suited for periodic investing:
- It supports fractional shares. Rather than having to buy whole shares of an ETF, it's possible to buy fractions of each fund in Curvo Growth. This means all your money is always put to work.
- Automatic investing with direct debit. Through Curvo, you can set up a monthly savings plan. Every beginning of the month, an amount you choose is debited from your bank account and automatically invested for you. Saving is easy when it's automated!
- No transaction costs. There are no Belgian transaction tax nor broker fees when investing with Curvo. So you're not paying more fees when investing monthly than investing a lump sum in one go. When investing through a broker, you're often penalised for investing more frequently because of the transaction fees.
Size of the funds: VWCE wins
The sizes of the funds in the Curvo Growth portfolio are €954 million and €82 million. This is smaller than VWCE, so there's a higher risk of Vanguard shutting down these funds than for VWCE.
However, you don't have to worry about this if you're investing with Curvo. If it were to happen, the funds will be replaced by suitable alternatives and your investments will automatically be brought over.
Sustainability: Curvo Growth wins
The Curvo portfolios are built according to one guiding principle: we don't support companies that we consider destructive to the planet. This means that certain types of companies are excluded from the portfolio:
- Companies in the fossil fuel industry.
- Companies that are active in vice products, like tobacco or gambling.
- Companies that do not meet the labour, human rights, environmental and anti-corruption standards defined by the United Nations Global Compact.
In contrast, all companies are included in VWCE, no matter how bad they are for the planet or society.
Verdict: Curvo Growth is best for monthly investing
Because of its support for fractional shares and the ability to automate monthly investments, Curvo Growth is the better option for periodic investing. It is also more diversified than VWCE. And perhaps most importantly, it is sustainable in that it excludes the companies that are destructive to the planet and society. However, investing with Curvo is more expensive than managing your own portfolio of ETFs with a broker.
Curvo: we do all the work for you
The difficulties of managing your own portfolio of ETFs
Choosing a single ETF like VWCE or IWDA is not the entire story when investing your life savings. Stocks are a risky asset class, and not everyone can psychologically handle their fluctuations. To bring success over the long term, you need to build a portfolio of ETFs that is suited to your goals, your appetite for risk and your capacity for taking risks. But this is not an easy task as there are thousands of ETFs to choose from. Furthermore, this portfolio of funds needs to be kept in balance over time, and adapt to changes in your life situation. When managing your own portfolio, these responsibilities fall onto you.
We saw most of our friends not investing because of these difficulties. Or they tried but stopped after a while because they didn't trust themselves enough to make the right financial decisions for their future. Yet, we think investing in ETFs or index funds is a powerful tool to improve our financial well-being. That's why we built Curvo: to take care of all the complexities of good investing so you don't have to worry.

- Withdraw anytime. There’s no long-term contract or exit fees if you wish to stop investing with Curvo.

Questions you may have
How do I buy IWDA?
Follow our guide to buy your first share of IWDA.
What ratio should I use when I'm combining IWDA with EMIM?
The current market share of emerging markets is about 12% of the total stock market. If you want to follow this ratio, it means that IWDA should be about 88% of your portfolio and EMIM the remaining 12%. You can deviate somewhat from this ratio. For instance, Curvo Growth contains 20% emerging markets instead of 12%. It exposes a bit more to emerging markets such as Brazil or China, at the expense of developed markets like the US or Germany.
