Recently, the Singapore bank DBS Bank released a flagship “Singapore 2040” report highlighting a bold forecast: the Singapore dollar (SGD) could reach parity with the U.S. dollar (USD) by around 2040. Simultaneously, the report suggests that Singapore’s benchmark stocks index, the Straits Times Index (STI), could rise to nearly 10,000 points by 2040, if historical patterns hold.
But this raises two important—and underdiscussed—questions:
- What must Singapore’s equity market do to get the STI from its current ~4,300 level (as of October 2025) to 10,000?
- Beyond just reaching that number, what would it take for the STI to compete in global investor interest and reach the influence of the U.S. indexes like the S&P 500, Nasdaq Composite and NYSE Composite?
In this article we explore the foundations behind the DBS projection, assess the key drivers and risks, and look at what it would mean for the STI to not just hit 10,000 but to sustain that level with meaningful international investor participation and regional/global relevance.
Current status: STI today
The STI has a long heritage: it tracks the performance of the top 30 largest and most liquid companies listed on the Singapore Exchange (SGX).
As of mid-October 2025, the STI sits at approximately 4,300 points in SGD.
Historically, the index has faced cycles of ups and downs. For instance, in March 2009 it fell to ~1,456 amid global crisis.
From the current base (~4,300) to 10,000 by 2040 implies more than doubling—roughly a 2.3× increase over ~15 years, a compound annual growth rate (CAGR) of about 6 %–7 % (depending on dividends, reinvestment, market conditions).
The estimated P/E (price-earnings) ratio of the Singapore market is around 14.2 as of mid-2025—relatively modest compared with many global peers.
Key driver #1: Economic growth and structural reforms
The DBS report ties the STI’s potential to Singapore’s broader economic prospects. They forecast that Singapore’s nominal GDP could more than double by 2040 (from ~US$547 billion in 2024 to ~US$1.2-1.4 trillion) on average real GDP growth around 2.3 % annually over the next 15 years.
If the economy grows, corporate earnings rise, and the stock market grows, then the STI has a foundation to reach higher. But growth alone is not enough: structural reforms matter—especially in opening up markets, boosting productivity, attracting foreign capital, and deepening the equity market.
Key reforms mentioned:
- The Monetary Authority of Singapore (MAS) is investing in a S$5 billion equity market development programme to boost liquidity, especially in small- and mid-cap stocks.
- Singapore’s role as a hub remains strong given its stable regulatory framework, open economy, and international connectivity.
Thus, if Singapore continues to transform from a matured economy into one with more innovation, deepening financial markets, and higher global integration, the STI stands a chance of achieving its target.
Key driver #2: Market valuation and investor behaviour
A critical input to the STI reaching 10,000 is how the market values the companies within that index—and how investor flows evolve, domestically and overseas.
Valuation
As noted, the Singapore market trades at a modest P/E (~14) compared to many developed markets. This suggests room for re-rating, but also that gains will need to come from earnings growth rather than just multiple expansion.
Investor behaviour & flows
For the STI to not only hit 10,000 but remain above it, domestic investors must remain active, and importantly, institutional and overseas investors must support the market. Why? Because Singapore’s domestic market is relatively limited in scale compared to the U.S., so sustained growth requires inflows of capital beyond just local money.
Some factors:
- Dividend yield has been one of the attractions of Singapore equities, relative to peers in Asia.
- Liquidity and trading volumes must improve so that overseas funds can enter/exit efficiently. The DBS report noted that average daily turnover in Q3 2025 rose by ~16 % to S$1.53 billion, the strongest since the third quarter of 2021.
- The composition of the STI matters: if more global-growth companies, technology firms, or regional champions list in Singapore, investor interest may increase.
Therefore, a homegrown market rally is necessary but not sufficient. The appeal of the Singapore market to foreign institutional investors (hedge funds, pension funds, asset managers) is an important lever.
Key driver #3: Depth, breadth and global relevance
For the STI to arguably match or approach the global indexes (S&P 500, NASDAQ, NYSE) in investor interest, there must be more than strong performance numbers: there must be global relevance.
Depth and breadth
- The STI tracks just 30 companies. Compare that to the S&P 500 (500 companies) or Nasdaq Composite (thousands). A narrow index makes the STI more vulnerable to concentration risk.
- For sustained growth and global appeal, Singapore must see a broader universe of sizeable listings, especially in high-growth sectors (tech, biotech, clean energy), which may attract more global capital.
Global relevance and investor interest
- Global funds often invest heavily in the U.S. markets partly because of size, liquidity, depth, innovation leadership, and the “brand” of the index. For the STI to rank globally in the same conversation, Singapore needs to showcase innovation, scale, global companies listing or headquartered here, and compelling sector stories.
- If the STI were to be considered alongside major global indexes for allocation decisions, then Singapore must attract global flows, maybe serve as a hub for Southeast Asia, or become the listing venue of choice for regional global growth companies.
Risk of being “domestically framed”
If the STI remains dominated by domestically-oriented companies with limited global growth story, overseas investor appetite may be limited. So part of the leap to 10,000 and beyond is the shift in narrative: from domestic utility/financial companies to globally-scaled growth stories.
Projecting the path: 2025-2040
Let’s outline a potential path for the STI to reach 10,000 by 2040 (15 years). This is illustrative, not prognostication.
Scenario assumptions
- Current STI: ~4,300 in 2025.
- CAGR needed to reach 10,000 in 2040 ≈ around 6.0-7.0% (depending on reinvested dividends).
- Earnings growth: Suppose Singapore companies grow earnings at 5% per annum on average (real+inflation) and valuations re-rate modestly by say 1% per annum in multiple expansion/earnings yield improvement.
- Domestic reforms/market improvement: Liquidity improves, more mid-cap listings, sector diversification, international investor flows increase.
- Global environment: Favourable for emerging/regional markets, Singapore remains politically and economically stable, currency stronger (SGD-USD moves close to parity).
Path of milestones
- 2025-2030:
- STI moves from ~4.3k to say ~5.5k–6.0k (CAGR ~5.5-6%).
- Gain in liquidity and local listing activity, more mid-cap stocks join or become investable.
- International interest begins to pick up.
- 2030-2035:
- Momentum builds, STI possibly 6.0k → ~8.0k.
- Singapore companies show stronger growth; foreign flows become more meaningful; valuation multiple improves slightly.
- 2035-2040:
- Final push: 8k → ~10k+.
- Market must demonstrate staying power (not just a bubble). Governance, depth, global investor trust, and Singapore’s currency strength all contribute.
If this path materialises, the STI hitting ~10,000 by 2040 becomes plausible.
What if the STI wants to match global indexes?
Let’s consider what “matching” the global indexes in investor interest and global reach would involve.
Global scale challenge
- The S&P 500, NASDAQ, and NYSE are large not just in points but in market capitalisation, number of listings, global investor flows, and brand/recognition. For example, global funds routinely invest in S&P 500 as a baseline allocation.
- Singapore’s total listed market is much smaller. So even if the STI hits 10,000, the index is still relatively small globally unless Singapore increases scale.
What would “match” entail?
- Broaden the listing base: More large-cap, globally relevant companies list in Singapore (e.g., technology, biotech, global consumer/regional champions).
- Increase foreign investor share: A noticeable percentage of STI market cap is held by foreign institutions, making the index sensitive to global allocations.
- Enhanced index branding: The STI becomes more frequently used in ETFs, global funds, passive strategies, “benchmarks” for Asia allocations.
- Inter-connectivity: Singapore attracts regional headquarters, global listings, cross-border capital. The STI becomes not just Singapore’s index but an Asian gateway index.
Feasibility and hurdles
- This is a stretch: it requires structural shifts in Singapore’s capital markets, regulatory incentives, and global company flows all aligning.
- The competition is strong: other regional exchanges (Hong Kong, Tokyo, Shanghai/Shenzhen, perhaps India) are also vying for listings and global capital.
- Global investor behaviour is often rooted in scale/liquidity. Singapore must reach a threshold where it is “large enough” to matter globally—and that may require the market cap of SGX-listed companies to grow significantly and attract more cross-listing or new economy firms.
Risks & challenges to the 10,000 target
While the 10,000 target is ambitious yet plausible, several risks could derail the path:
1. Global headwinds
A global recession, higher interest rates, geopolitical tensions can reduce risk appetite for equities globally — regional markets like Singapore may be more affected.
2. Domestic stagnation
If Singapore’s growth slows, or the economy fails to transform (e.g., lack of innovation, lack of new listing activity), earnings growth may stagnate, reducing the STI’s upward potential.
3. Valuation ceiling
If the market already trades at modest valuations, earnings growth alone may not suffice. Without multiple expansion, the path to 10,000 could be slower.
4. Liquidity/scale constraints
As mentioned earlier, for the STI to grow sustainably past 10,000, offshore/international flows are critical. If SGX fails to attract new listings, fails to deepen the market, or faces outflows, the index may struggle to attract the momentum.
5. Currency & external shock risk
Given Singapore’s open economy, external shocks (trade disruptions, regional tensions, currency depreciation) will impact corporate earnings and investor confidence.
6. Investor mind-share
Even if the STI hits 10,000, if global funds still view it as a “small market” or limited opportunity, foreign flows may be muted, limiting the upward momentum.
Why the DBS projection deserves attention
The projection by DBS is noteworthy for several reasons:
- It ties the STI target to a credible macro-framework: Singapore’s economic growth, currency outlook (SGD-USD parity), market reforms. (See: DBS’s note that the STI “could rise to nearly 10,000 by 2040 if historical return patterns hold”.)
- It calls out that Singapore is entering a “medium-term bullish shift” having already broken past 4,000 in 2025 after a 17-year stalemate.
- It underscores that for stock market gains to last, structural change is required: including attracting listings of high-growth firms and raising liquidity. The report pointed out: “Singapore faces a critical juncture in attracting high-growth technology companies to list locally rather than on international exchanges.”
In short: the STI’s path to 10,000 is not just about waves in the general market tide — it’s about transformation, deeper market structure, and global investor participation.
Strategic implications for investors
For investors watching this proposal, here are some strategic implications:
Stay attuned to structural signals
- Monitor SGX listing activity: Are more mid-cap/high-growth companies listing in Singapore?
- Watch liquidity metrics (daily turnover, foreign investor share) increasing meaningfully.
- Track valuation metrics: P/E, dividend yields, price-to-book for the market and compare regionally/ globally.
Diversification & timing
- If you believe in the 10,000 target, starting small allocations now may benefit from the long-horizon growth potential.
- Because the target is long-term (15+ years), investors should be mindful of interim volatility, structural risk, and not anchor purely on the 10,000 point number.
Global vs local balance
- If the STI starts to attract more global flows, it may become less correlated with purely domestic Singapore risks—this could lower systemic risk and make the Singapore market a more integral part of Asia-Pacific equity allocations.
- But if the index remains dominated by domestic companies and lacks global appeal, it may continue to trade more as a local play with limited upside relative to higher-growth markets.
Currency risk
- With the SGD-USD correlation and DBS forecasting parity by 2040, currency strength will help returns in SGD terms for foreign investors and support the valuation environment for companies that earn or export globally.
Can the STI match the global indexes in investor interest?
We turn back now to the question of whether the STI can reach parity with the U.S. stock indices in terms of global investor interest and reach. The answer: conditionally yes—but it faces an uphill climb.
What “parity” might mean
- Not necessarily equal in size or market cap (which is unlikely), but comparable in terms of being a core part of global/international equity allocations—where institutional funds consistently allocate to Singapore as they do to the U.S. markets.
- Being part of global ETFs, passive funds, international asset-allocation frameworks that treat the STI or Singapore market as “must-hold” rather than “emerging/specialty”.
- Having global visibility: companies in the STI being known to global investors, following global growth themes (digital economy, sustainability, Southeast Asia growth).
What Singapore must deliver
- Larger-scale, globally-relevant companies listing on SGX, or global companies choosing Singapore as a hub.
- Deeper capital markets: more mid/small-cap liquidity, more product offerings (ETFs linked to STI, derivatives, foreign investor access).
- Foreign investor comfort: regulatory environment remains transparent, cross-listing, currency risk is manageable, corporate governance credible.
- Narrative shift: from “Singapore market = old-economy utilities and banking” to “Singapore market = dynamic, Asia-Pacific growth story”.
Realistic expectation
- While matching the S&P 500 or Nasdaq in sheer scale is unrealistic (given U.S. market size, number of companies, depth, and global dominance), Singapore could become a regional gateway and gain significantly in global investor mind-share.
- In our scenario above, if the STI hits 10,000 and has improved fundamentals, it might be treated as a “tier-2” global market with meaningful foreign flows—and that is already an improvement from a merely domestic-focused index.
Conclusion: What to watch going forward
To summarise: The DBS projection that the STI could reach 10,000 by 2040 is ambitious but not outlandish. It rests on a mix of macro growth, market reforms, valuation expansion, and investor flows. However, the leap from “potential” to “sustained reality” will require Singapore to evolve its equity market structure and global positioning significantly.
Some key watch-points for the next 5–10 years:
- Listing environment: Are more large-growth/technology companies listing in Singapore rather than abroad?
- Institutional/foreign flows: Is foreign ownership of SGX-listed stocks rising? Is trading volume increasing?
- Corporate earnings growth: Do Singapore’s major companies deliver earnings growth beyond the moderate domestic growth rate?
- Valuation dynamics: Does the market P/E expand, or will gains be limited to earnings growth only?
- Global narrative and positioning: Does Singapore become a more prominent part of global investor portfolios, or does it remain domestically focused?
If these dynamics align well, the STI reaching 10,000 by 2040 may be within reach—and the ambition of becoming a more globally relevant index could also materialise. Conversely, if structural reforms stall, global risk appetite declines, or investor flows bypass Singapore, then the target may be harder to hit and sustain.
For investors and market watchers, the 10,000 target is a useful anchor point—but it should not be taken as a guarantee. The path there will be lit by deeper transformation in the Singapore market, not just favourable macro headlines.
