STI Breaks 5,100: Is Singapore’s Bull Run Just Getting Started?

The Straits Times Index (STI) has done it again. The benchmark breached the 5,100 mark for the first time today, on 3 June 2026, extending a historic run that has turned Singapore into one of the most compelling equity markets in Asia this year. 

For investors who have been watching from the sidelines, the message from the market is getting louder: this rally has fundamental legs. 

What Just Happened 

The STI climbed past 5,100 points this week, building on a fresh all-time intraday high of 5,073.11 reached on 21 May 2026, despite broader global uncertainty, elevated oil prices, and ongoing Middle East tensions. 

The catalyst for this week’s push? Singapore’s three heavyweight banks, DBS, OCBC, and UOB, which together account for more than 50% of the index’s weight, continued their march to record territory. 

DBS has been reaching fresh all-time highs as investors increasingly focus on the bank’s wealth management franchise, with the bank recording close to S$10 billion in net new money inflows in Q1 2026 alone. OCBC has been a strong performer among the three Singapore banks in 2026, up approximately 23% year-to-date, with wealth-related income now contributing around 39% of group earnings. UOB, meanwhile, trades at around 14 times earnings, with a dividend yield profile that income-focused investors may find attractive. 

Why This Rally Is Different 

Past STI surges have often been one-dimensional: banks go up, everything else follows briefly, then fades. This time, the breadth of the rally points to something more structural. 

Singapore’s GDP grew 6.0% in Q1 2026, beating the government’s own advance estimate of 4.6% and marking the strongest annual growth since Q3 2024, fuelled largely by AI-driven demand in the electronics and manufacturing sectors. Enterprise Singapore has raised its full-year non-oil domestic exports forecast to +3 to 5%, among the strongest in several years. The Singapore Overnight Rate Average (SORA) has stabilized at under 1%, a significant drop from its 2023 peak of 4%, easing financing pressures across REITs, developers, and leveraged businesses. 

At the same time, global capital appears to be rotating. With US equity valuations stretched, institutional money has been looking for markets that offer quality, yield, and more reasonable valuations. The STI currently trades at approximately 16 times earnings with a dividend yield of around 3.3-3.5%, and those dividends are tax-free for Singapore investors. 

The Johor-Singapore Special Economic Zone (JS-SEZ) adds another dimension to the growth story, with supply chain and logistics opportunities that could benefit industrial names like ST Engineering (SGX: S63), while the AI infrastructure build-out has lifted data centre-linked REITs such as Keppel DC REIT (SGX: AJBU). 

The Risk Flags to Watch 

No article on a market at record highs is complete without addressing the risks. 

Energy prices remain elevated. A breakdown in ceasefire talks could push oil back toward the highs, reigniting global inflation fears and putting renewed pressure on rate expectations. Any shift in the MAS’s monetary policy stance, which has kept policy steady while raising its 2026 inflation forecast to 1 to 2%, could also affect rate-sensitive segments like REITs. And at the global level, escalating tariffs on Singapore exports would squeeze corporate margins and weigh on earnings visibility. 

These are real risks. But they are not new risks. The STI has absorbed significant geopolitical uncertainty throughout this rally, and its resilience in the face of these headwinds is worth noting. 

Positioning for the Move: Share Financing on NOVA

For investors confident in Singapore’s market outlook, Share Financing on NOVA lets you amplify your exposure to this rally, increasing your purchasing power beyond what your cash position alone allows.

• Phillip Nova offers USD and SGD share financing at just 4.5% p.a.

There are two ways to think about deploying Share Financing in the current environment. For index exposure, the SPDR STI ETF (SGX: ES3) and Amova AM STI ETF (SGX: G3B) offer broad STI participation, with dividends of around 3.5% helping to partially offset financing costs while you ride the index’s price appreciation. For a dividend carry approach, selectively picking blue chips with yields above 4.5%, such as DBS (SGX: D05), which currently offers a dividend yield of around 5%, means dividend income may cover the financing cost, leaving price upside as potential additional gain.

As with all financing strategies, position sizing and risk management are essential. Financing amplifies both gains and losses, so maintaining sufficient buffers to weather short-term volatility is key.

The Bottom Line

The STI crossing 5,100 is not just a headline number. It reflects a market backed by strong earnings, improving macro fundamentals, and sustained capital inflows. Singapore’s equity story in 2026 has been built on substance, not sentiment alone.

With technical momentum intact and the fundamental backdrop remaining supportive, the STI may have further room to run. For investors who want greater exposure to this move, Phillip Nova’s Share Financing, at a competitive 4.5% p.a. for both SGD and USD, provides the leverage to make that conviction count.
