STI, Malaysia, Indonesia Stocks Fall as Oil Surpasses $100

Asian markets experienced a significant downturn as investor anxiety regarding regional conflicts and rising oil prices escalates. On March 6, 2023, the Straits Times Index (STI) registered a decline of 1.9 percent, following an initial dip of 3.1 percent. Other Southeast Asian markets also faced reductions, with the Kuala Lumpur Composite Index dropping by 2.6 percent and the Jakarta Stock Exchange Composite Index falling by 3.3 percent.
Rising Oil Prices Impact Investments
Oil prices surged beyond $100 per barrel, reaching levels not seen since mid-2022 following Russia’s invasion of Ukraine. West Texas Intermediate crude reached over $117, marking a 29 percent increase. Brent crude oil prices similarly jumped by 28 percent to $118.73, representing its most substantial rise in nearly six years. These developments have triggered widespread concerns among investors.
Geopolitical Risks and Inflation Concerns
Selena Ling, chief economist at OCBC Group Research, indicated that heightened geopolitical risks could have profound consequences. Singapore, as a net importer of crude oil and liquefied natural gas, might experience significant economic impacts similar to those seen during the Gulf War. If the current oil price trend continues, inflation could rise, challenging the earlier economic forecasts.
- Current oil price estimates:
- West Texas Intermediate: Over $117
- Brent Crude: $118.73
- Potential inflation rates:
- Pre-war assumption: $63 per barrel correlates to 1.8% inflation
- Sustained average of $92 could push inflation beyond 2%
Such price pressures may prompt the Monetary Authority of Singapore to reconsider its monetary policies much sooner than expected, as OCBC emphasized the region’s ability to enact flexible fiscal measures could mitigate rising costs.
Regional Market Responses
In response to the volatility, several key players within the aviation sector are also feeling the strain. Singapore Airlines, a prominent carrier, saw its shares decline by 2.4 percent due to increased jet fuel costs. Conversely, ground handler SATS was identified as a potential beneficiary of shifting logistics, despite a 3.8 percent downturn in its shares.
Wider Asian markets showed similar trends, with Hong Kong’s Hang Seng Index dropping by 1.4 percent, and the CSI 300 in Shanghai finishing 1 percent lower. The Nikkei 225 in Japan fell by 5.2 percent, with South Korea’s Kospi down 6 percent, along with a 2.9 percent decline in Australia’s ASX 200.
Currency Impact and Future Outlook
Emerging markets may face varied repercussions from fluctuating oil prices. Malaysia, a net oil exporter, may receive some protective benefits, while countries like the Philippines encounter downward pressure on their currencies. Thailand’s market, with an energy deficit of 4 percent of its GDP, might experience even more severe impacts.
OCBC’s analysis indicated that currency fluctuations are significantly influenced by oil price exposure and market risks, with the South Korean won and Philippine peso being particularly vulnerable. Meanwhile, the Malaysian ringgit is somewhat insulated due to its oil exports, while the Chinese yuan and Singapore dollar remain strong.
As the situation unfolds, central banks in the region may be compelled to alter their monetary policies to address inflation and currency stability. Under extreme scenarios where oil prices spike significantly, some countries may face the prospect of increasing interest rates, potentially hampering economic growth.
