STI Weekly Commentary: Geopolitical Tensions Weigh on Sentiment as Energy and Defensive Stocks Show Resilience
Market Overview and STI ETF Performance
The trading week from 23 to 27 March 2026 presented a mixed picture for the Straits Times Index (STI) constituents, characterised by underlying resilience amidst a challenging global backdrop. According to the Excel data, the index’s average daily change was a positive 0.46%, with 18 stocks advancing against 4 decliners and 8 unchanged on the latest trading day. This suggests a degree of domestic stability. However, the broader narrative was heavily influenced by persistent geopolitical strife, as detailed in multiple news reports concerning the ongoing conflict in the Middle East and its ripple effects on global trade, energy prices, and market sentiment. The SPDR STI ETF, a proxy for the broader Singapore market, closed the final trading day unchanged at $4.90, having recovered from a mid-week low of $4.835, and trading within the upper half of its 52-week range ($3.393 - $5.109). This flat performance for the ETF, juxtaposed with the positive average move of constituents, indicates a divergence where gains in some sectors were offset by pressures in others, a dynamic clearly reflected in the sector performance data. The market appeared to be navigating what BlackRock’s Larry Fink described in his 2026 Annual Chairman’s Letter (23 March 2026) as a world “reorganizing around self-reliance,” a shift he noted would be expensive and push more financing onto capital markets.
Sector-by-Sector Analysis
A sectoral breakdown of the Excel data reveals a clear bifurcation in performance, largely aligned with global macroeconomic winds. The Energy sector, represented solely by Seatrium Ltd, was the week’s standout performer with an average daily gain of 2.62%. This strength is directly correlated with elevated oil prices stemming from the Middle East conflict, as reports highlighted how the war was causing an energy shock and driving up costs. The Utilities sector, represented by Sembcorp Industries, also gained 1.72% on the day, benefiting from the same elevated energy environment. Consumer Defensive stocks, including Thai Beverage and DFI Retail Group, and Wilmar International, also outperformed with a 2.21% average gain. In times of uncertainty, investors often flock to companies producing essential goods, a trend that held true this week.
The Financial Services sector, a heavyweight pillar of the STI including the three local banks, posted a modest average gain of 0.38%. These banks, particularly DBS and OCBC which are trading near their 52-week highs, are seen as relatively stable havens. Their performance was likely supported by news of United Overseas Bank (UOB) mobilising significant sustainable finance, showcasing the sector’s adaptive growth strategies. However, the sector is not immune to broader economic pressures, including potential credit risks from regional exposures, as hinted at by news of manufacturing strains in Indonesia.
The Real Estate sector, encompassing 12 REITs and property developers, averaged a slight gain of 0.32%. This muted performance reflects the sector’s sensitivity to interest rate expectations, which remain uncertain due to inflationary pressures from the energy shock. Stocks like CapitaLand Ascendas REIT saw unusually high volume, potentially indicating investor repositioning. News of an improving apartment market in some regions provided a slight counter-narrative, but local REITs faced headwinds, with Frasers Centrepoint Trust and Mapletree Logistics Trust among the week’s losers.
The Industrials sector was the notable laggard, averaging a decline of 0.52%. This weakness can be attributed to its exposure to global supply chains and project delays, which are vulnerable to the very geopolitical and trade tensions dominating the headlines. Articles detailed how Trump’s tariffs are choking U.S.-China trade and how global trade forecasts are at risk, directly impacting industrial conglomerates. The Technology sector, represented by Venture Corporation, also dipped slightly by 0.32%, possibly reflecting global tech volatility and concerns highlighted in news about Singapore firms facing high ransomware risks.
Top Gainers and Losers Analysis with Reasons
The list of top gainers for the latest day provides a snapshot of where money flowed amidst the uncertainty. Seatrium Ltd led the pack with a 2.62% surge, also registering 2.4 times its average volume. This aligns with its classification as a satellite stock with high revenue growth (17.0%) and its direct benefit from the global energy security drive and potential naval defence contracts linked to geopolitical tensions. Thai Beverage (+2.35%), trading near its 52-week low, presented a classic “value and yield” play, boasting an exceptionally high dividend yield. Its defensive characteristics attracted investors. Wilmar International (+2.16%), also near a 52-week high, likely gained on renewed concerns about global food security, as news reports indicated war-driven disruptions were pushing Central Asia to rethink agriculture, potentially benefiting global agri-business leaders.
Conversely, the top losers list reveals the pressure points. Keppel Ltd. was the biggest decliner, falling 3.02% on double its average volume. As a diversified industrial with global operations, it is acutely exposed to the negative factors plaguing the sector: supply chain disruptions, rising costs from the energy shock, and broader capex caution. Jardine Matheson (-1.89%), with its vast international exposure, similarly faced headwinds from global market volatility, as Asian markets were reported to be slumping due to the escalating Middle East conflict. The minor declines in Venture Corporation and Hongkong Land reflect the cautious stance towards tech and specific regional property markets.
Volume and Momentum Analysis
Unusual trading volume often signals a shift in investor interest or the digestion of significant news. The Excel data highlighted several stocks with volume exceeding 1.5 times their average. Mapletree Logistics Trust (2.7x), Seatrium (2.4x), Sembcorp Industries (2.4x), and Keppel Ltd. (2.0x) all saw heightened activity. For Seatrium and Sembcorp, the high volume accompanied price gains, confirming strong bullish interest, likely driven by the energy crisis narrative. For Mapletree Logistics Trust and Keppel, the high volume came with price declines, suggesting institutional selling or profit-taking in the face of sector-wide concerns.
Momentum indicators from the data provide further clues. Several major stocks, including DBS, UOB, Jardine Matheson, and City Developments, were trading below their 50-day moving averages but above their 200-day averages. This technical pattern often describes a “potential dip buy” scenario, where a short-term pullback occurs within a longer-term uptrend. For novice investors, this highlights blue-chip names that may be experiencing a temporary discount due to market-wide risk aversion rather than company-specific issues.
Impact of Macroeconomic or Geopolitical Factors
The dominant theme shaping market performance is unequivocally geopolitical. The provided news articles paint a consistent picture of a world grappling with the economic consequences of conflict. The war in the Middle East is not just a regional issue; it is a global macroeconomic shock. It has directly propelled energy prices, benefiting Seatrium and Sembcorp but hurting energy-intensive industrials and stoking inflation fears. As Reuters reported, Asian stocks were swept up in a global rout due to the threat of a protracted energy shock sending borrowing costs higher.
Furthermore, the conflict is disrupting global trade and supply chains. The WTO warned that global trade growth is at risk, and reports show Indonesian manufacturers being hit by a double squeeze from Middle East energy costs and domestic gas shortages. This directly impacts Singapore’s open, trade-reliant economy and its industrial and manufacturing stocks. Additionally, the news of Asian family offices reconsidering Dubai as a wealth hub underscores how geopolitical instability can redirect capital flows, with Singapore potentially standing to benefit as a stable alternative.
Parallel to this is the ongoing tension in U.S.-China trade. Articles detail how Trump’s tariffs are choking trade between the world’s two largest economies. This persistent friction encourages a move towards economic self-reliance, or “reshoring,” which Larry Fink noted would strain capital markets but also create opportunities for companies involved in regional supply chains and infrastructure, potentially benefiting certain Singaporean industrials and logistics players in the long run.
Portfolio Strategy Recommendations (Core vs Satellite)
In such a volatile environment, a balanced portfolio strategy distinguishing between core and satellite holdings is prudent. Based on the Excel data’s classification:
Core Holdings should form the foundation. These are large-capitalisation stocks with stable operations, lower volatility (low beta), and often strong institutional ownership. They are designed to provide stability and steady dividend income. Ideal candidates from the data include the local banking trio (DBS, UOB, OCBC), which are trading robustly and have manageable beta. Singapore Telecommunications (beta 0.32) and Singapore Technologies Engineering (beta 0.24) also fit this profile, offering essential services and defence exposure, respectively. CapitaLand Integrated Commercial Trust (beta 0.48) represents a stable, large-scale real estate exposure for the core portfolio.
Satellite Holdings are for targeted growth and can tolerate higher risk. These stocks have higher growth profiles or sensitivity to specific themes. Currently, the energy transition and defence themes are powerful. Seatrium (beta 0.35, 17% revenue growth) is a prime satellite candidate, directly leveraged to offshore renewable and conventional energy projects. Sembcorp Industries (low beta but high growth potential in green energy) also fits as a thematic satellite play. For exposure to digital infrastructure, Keppel DC REIT (beta 0.85, 50.3% revenue growth) is a high-growth, higher-risk option. Yangzijiang Shipbuilding (beta 0.83, 15.8% growth) offers cyclical growth potential in shipbuilding.
Given the high-yield environment, Thai Beverage, despite its satellite-like volatility, could be considered for a satellite income portion, but investors must be cautious and research the sustainability of its extraordinary yield. The key with satellite holdings is to size positions appropriately, understanding that their prices will fluctuate more dramatically with news flow, as seen this week.
Outlook for the Coming Week
The outlook for the coming week remains tightly coupled to geopolitical developments. Markets will continue to react to any headlines regarding the Middle East conflict, oil price movements, and central bank commentary on inflation. The data shows the STI has underlying strength, with more advancers than decliners, but it is not insulated from global storms. Barclays’ strategist Ajay Rajadhyaksha’s advice to investors to “keep climbing that wall of worry” (CNBC, 26 March 2026), maintaining a bullish stance on equities despite risks, may offer some perspective, but caution is warranted.
Sectors likely to remain in focus include Energy (Seatrium) and Utilities (Sembcorp), which may see continued interest if oil prices stay elevated. Consumer Defensive stocks could retain their safe-haven appeal. The Financials sector may experience volatility depending on bond yield movements but should provide relative stability. The Real Estate and Industrial sectors may remain under pressure until there is clearer evidence of peaking interest rates and easing supply chain disruptions.
Investors should monitor the multi-day trends identified in the Excel data. Stocks like DFI Retail, Sembcorp, and Singapore Exchange demonstrated strong weekly upward momentum and may continue to outperform if their sectoral tailwinds persist. Conversely, the weekly losers like Keppel DC REIT (which despite its near-term weakness retains strong long-term growth credentials as noted in the satellite recommendations above) and Keppel Ltd. may need a change in the macro narrative to reverse their trends. Ultimately, in a market driven by external shocks, maintaining a disciplined strategy focused on quality core holdings, complemented by carefully selected thematic satellite positions, appears to be the most sensible approach for navigating the uncertainty ahead.
