What Should I Do With $100,000?

 

Three general approaches, compared on the same basis: expected return, effort, and reversibility

$100,000 is large enough to move the needle on a Singaporean's finances, but where it should go depends on what stage of life you're in and how much ongoing work you're willing to put in to keep it compounding. There are three general approaches worth comparing: put it into yourself, put it into the world's stock markets through a low-cost fund, or put it into SGX income assets that pay you cash every quarter. Each has a different return profile, time horizon, and level of ongoing effort required.

1. Grow human capital: a credential that raises your income

For a younger person, the highest expected return on $100,000 is often not in a portfolio at all. It is in raising your own earning power, because a salary increase compounds over the 20 to 30 working years still ahead of you, in a way that a lump sum invested at market returns cannot match on the same time horizon.

The INSEAD MBA is a useful reference point because the numbers are public. INSEAD's own financing page puts full tuition at €109,860, with total cost of attendance (tuition plus a year of living expenses) at roughly €140,000, or about S$200,000 at current exchange rates. $100,000 does not cover that on its own. What the salary outcomes show is why people still borrow the difference or draw down savings to make up the gap: INSEAD's latest employment report puts median base salary post-MBA at €100,000 (roughly S$145,000), a 111% increase over pre-MBA salary, plus a median signing bonus of €28,900.

This is why the approach specifically favors younger people. A 28-year-old who doubles their base salary captures that uplift, compounding through raises and promotions, for another three decades. A 50-year-old capturing the same percentage increase has a much shorter runway to compound it, and by then may have less appetite for a year without income. The expected return here is real but not guaranteed the way a bond coupon is: it depends on the specific program, the specific industry you're targeting, and your ability to convert the credential into an actual offer. Not every credential pays off like an INSEAD MBA. A CFA, a specialist diploma, or a technical certification can produce a similar effect at a fraction of the cost, which is often the more sensible use of $100,000 for someone not aiming at a top-tier full-time MBA specifically.

2. Globally diversified UCITS ETFs on the London Stock Exchange

For $100,000 that isn't going toward a credential, the next question is how much ongoing effort you want to put in. A globally diversified UCITS ETF, domiciled in Ireland and traded on the London Stock Exchange, is close to the lowest-effort option available: buy, hold, rebalance occasionally, and let the index do the work.

Two commonly used building blocks are the Vanguard FTSE All-World UCITS ETF (VWRA, accumulating) and the iShares Core MSCI World UCITS ETF (IWDA), both giving exposure to well over a thousand companies across developed and emerging markets in a single trade. Ireland-domiciled UCITS funds are the standard choice for non-US investors, specifically because they avoid US estate tax exposure and benefit from a more favorable dividend withholding tax treaty than a US-domiciled ETF held directly.

On returns, be careful with the headline number. VWRA's average annual return since its 2012 inception has been about 13.4%, but that period captured an unusually strong bull run in US equities. [Source: stockanalysis.com, VWRA historical performance.] For planning purposes, a more conservative long-run assumption of 6 to 8% a year is the more defensible number, in line with long-run global equity history before the 2010s. At 7% per year, $100,000 grows to roughly $197,000 in ten years and $387,000 in twenty years, before any further contributions. This is a total-return vehicle, not an income vehicle: there is no cash paid out to live on unless units are sold, and it carries the full volatility of global equities. Currency exposure (the fund is USD-denominated; your costs are in SGD) is a real variable too.

3. Dividend stocks: banks, REITs, business trusts and SDRs on SGX

The third approach is building a portfolio for cash income rather than total return, using SGX-listed banks, REITs, business trusts, and Singapore Depository Receipts (SDRs). At current levels, a 5% blended yield is achievable without reaching for yield traps: DBS trades around a 4.6% trailing yield, OCBC around 5.9%, and UOB around 5.0%. [Source: StashAway Singapore, DBS/OCBC/UOB 2026 outlook.] S-REITs typically yield 4 to 6%, a function of the regulatory requirement to distribute at least 90% of taxable income, and business trusts, backed by contracted, often regulated cash flows, can run 5 to 8%. SDRs provide access to a small basket of Thai blue-chips in SGD, but the segment is newer and less liquid, and is better treated as a satellite than a core income holding.

The arithmetic is simple: $100,000 at a 5% blended yield is about $5,000 a year in additional income, paid mostly in quarterly installments. What the arithmetic does not show is the ongoing work. Unlike the ETF approach, this is not a buy-and-forget portfolio. It requires continuing to check that the dividend is covered by free cash flow rather than just the headline yield, watching balance sheet risk and refinancing schedules, and reinvesting distributions with the same discipline. That work does not stop once the first $100,000 is deployed. It continues for as long as you keep building your portfolio, which, for most people pursuing financial independence, means years, not a single transaction.

Comparing the three

Approach	Expected return / income	Ongoing effort	Best suited to
Human capital (credential)	High but uncertain; compounds through career, not the portfolio	High upfront (1-2 years), then none	Younger people early in their career
Global UCITS ETF (LSE)	~6-8% total return p.a. (conservative planning assumption)	Very low: buy, hold, rebalance	Investors who want low effort and full market exposure
SGX dividend portfolio	~5% cash yield, roughly $5,000/year on $100,000	Continuous: monitoring, reinvestment, position sizing	Investors building a spendable income stream toward financial independence

The honest answer

Personal finance is personal. The right split across these three depends on your age and how many working years are left to compound a salary increase, how much of your net worth is already tied up in CPF and property, and whether you actually have the temperament to keep doing the ongoing work that option three demands. A 26-year-old with most of their net worth still ahead of them gets more out of option one than a 55-year-old does. Someone who wants to set it and forget it is better served by option two than by a dividend portfolio they won't maintain.

I've run option three for over two decades. It was not the lowest-effort choice, nor was it guaranteed to outperform a global index fund over that period. What it gave me was a growing stream of cash income I could see and use, the discipline of checking dividend coverage rather than chasing yield, and a fit for a temperament that wanted to stay actively involved in the portfolio rather than hand the decision to an index. That is a personal fit and not a universal recommendation. The framework above is what I'd use to help someone else find theirs.
