Singapore's Inflation Hits 1.8% in March Amid Petrol Price Surge
Singapore's consumer price index for all items climbed to 1.8 percent year-on-year in March 2026, up sharply from 1.2 percent the previous month. This acceleration marks a notable shift after months of moderation, primarily triggered by escalating petrol and diesel costs linked to the ongoing Iran war. Private transport inflation, a key component, jumped to 6.6 percent from 2.4 percent, reflecting the direct hit from fuel prices that have surged past previous highs set during the Russia-Ukraine conflict in 2022. Core inflation, which strips out volatile accommodation and private transport costs, also rose to 1.7 percent from 1.4 percent, signaling broader price pressures beginning to embed across the economy.
The Monetary Authority of Singapore (MAS) and Ministry of Trade and Industry (MTI) highlighted that higher retail goods and services costs contributed to the uptick. While food inflation held steady at 0.6 percent, with non-cooked food edging up slightly offset by softer food services, the energy shock is poised to ripple further into electricity tariffs, logistics, and everyday groceries as businesses pass on elevated input costs.
Timeline of the Middle East Conflict and Its Oil Market Shock
The catalyst traces back to late February 2026, when escalating tensions between the United States, Israel, and Iran culminated in military actions that effectively restricted shipping through the Strait of Hormuz. This vital chokepoint handles about 20 percent of global oil flows and a significant share of liquefied natural gas. Iran's retaliatory measures, including threats and partial blockades, slashed supplies, propelling Brent crude prices upward by over 30 percent in weeks, peaking near US$114 per barrel before some stabilization.
Singapore, as Asia's premier oil trading and refining hub, felt immediate repercussions. With roughly 55 percent of its oil imports originating from the Middle East, the nation faced acute supply tightness. Bunker fuel prices, critical for its shipping industry, hit historic highs, while spot cargoes became scarce. By early March, refiners were rationing inventory, and lead times for deliveries extended dramatically. This chain reaction not only spiked spot fuel prices but also disrupted downstream sectors reliant on stable energy inputs.
Petrol and Diesel Prices: The Numbers and Daily Impact
At petrol stations across the island, prices for 95-octane unleaded fuel climbed to between S$3.40 and S$3.42 per litre by late March, surpassing levels from the 2022 energy crisis. Shell, Esso, Caltex, and others adjusted pumps multiple times weekly, with premium 98-octane nearing S$4.00. Diesel, used heavily in commercial fleets, outpaced petrol hikes, exacerbating costs for logistics firms.
For the average motorist, this translates to an extra S$20-30 per full tank, compounding monthly expenses. Ride-hailing drivers and taxi operators report earnings squeezes, with some reducing trips or seeking fuel efficiency upgrades. Public transport users remain somewhat insulated via subsidized fares, but operators like SBS Transit and SMRT face ballooning diesel bills, potentially pressuring future adjustments.
Breaking Down the CPI: Where Pressures Are Building
The Consumer Price Index (CPI) basket reveals targeted vulnerabilities. Private transport's 6.6 percent surge dominated the headline figure, but core components showed momentum too. Retail and other goods inflation accelerated to 1.8 percent, fueled by pricier alcohol, tobacco, clothing, and footwear—items sensitive to global shipping disruptions.
Services edged to 2.1 percent, with point-to-point rides and telecom costs rising as operators absorb fuel hikes. Electricity and gas bucked the trend, down 4.3 percent year-on-year due to lagged tariff adjustments, but the Energy Market Authority (EMA) confirmed Q2 increases based on January-March gas prices, which spiked amid the Hormuz constraints.
| CPI Component | March 2026 y-o-y | February 2026 y-o-y |
|---|---|---|
| All Items | 1.8% | 1.2% |
| Core | 1.7% | 1.4% |
| Private Transport | 6.6% | 2.4% |
| Retail & Other Goods | 1.8% | 0.6% |
| Services | 2.1% | 2.0% |
| Food | 0.6% | 0.6% |
Food away from home held firm, but imported staples like rice and meats face upward risks as freight costs climb. Accommodation inflation lingered at 0.3 percent, buoyed by softer rentals.

MAS Steps In: Policy Tightening and Revised Forecasts
On April 14, the MAS announced a slight steepening of the Singapore dollar nominal effective exchange rate (S$NEER) appreciation path—its first adjustment since 2022—to counter imported inflation. Forecasts for both core and all-items CPI were lifted to 1.5-2.5 percent for 2026, from 1.0-2.0 percent, citing persistent energy pass-throughs even post-Hormuz reopening.
"The trajectory of inflation beyond 2026 will depend heavily on global energy and food prices," MAS noted, underscoring uncertainties from the conflict's duration. GDP growth for Q1 clocked 4.6 percent year-on-year, but full-year prospects dimmed toward trend levels around 2-3 percent, weighed by energy-dependent sectors like petrochemicals.

Sectoral Ripples: Transport, F&B, and Beyond
Land transport bears the brunt, with bus and truck operators confronting diesel hikes of over 40 percent. Food and beverage outlets anticipate menu repricing as ingredient logistics costs soar—think higher freight for imports from Europe and the US, rerouted around conflict zones.
Property developers face elevated construction material costs, while aviation sees jet fuel premiums squeezing airlines like Singapore Airlines. Bunkering, a pillar of the economy, grappled with record prices, rationing, and contract delays, though some recovery emerged post partial Strait reopening.
Small and medium enterprises (SMEs), comprising 99 percent of firms, report 2-in-3 impacted, per polls, with energy bills up 20-30 percent. Larger refiners pivoted to alternative sources like the US and Australia, but at premium rates.
Household Budgets Under Strain: Consumer Adaptations
Singaporeans are recalibrating. Surveys show 88 percent anticipating higher inflation, prompting cutbacks on discretionary spends like dining out and travel. Some stockpile fuel or switch to hybrids; others carpool or embrace MRT expansions.
Comforts like air-conditioning persist despite utility warnings, but grocery tweaks—opting for local produce or bulk buys—emerge. Low-income households, cushioned by utilities subsidies, still feel grocery pinches as non-cooked food inflation brews.
Government Buffers and Long-Term Resilience Plays
Authorities rolled out targeted aid: enhanced utilities rebates, CDC vouchers, and fuel duty tweaks to blunt pass-throughs. EMA's tariff formula delays shocks, buying time for diversification.
Strategic petroleum reserves cover 100+ days of needs, while LNG imports ramped via spot tenders from Qatar and Australia. Forward moves include solar incentives—rooftop capacity tripled since 2022—and hydrogen pilots, aiming for 30 percent clean energy by 2030. For more on energy resilience, check CNA's analysis.

Global Context and Regional Peers
Singapore leads ASEAN in policy responsiveness, but neighbors like Vietnam (3.5 percent inflation) and Philippines face steeper hits from rice and power dependencies. Globally, IMF flags stagflation risks if oil lingers above US$100, trimming world growth to 2.5 percent.
- Japan: Yen weakens, import costs amplify.
- India: Subsidy strains amid 7 percent rupee inflation.
- Europe: Recession odds rise with halved GDP forecasts.
Outlook: Scenarios and Actionable Steps
If the conflict de-escalates by mid-year, inflation peaks at 2.5 percent before fading to 1 percent in 2027. Prolonged closure risks 4 percent CPI, growth dip to 1.5 percent. Businesses hedge via fixed contracts; households track EMA alerts, leverage SkillsFuture for green jobs.
