You’ve seen the wild headlines. The Strait of Hormuz has been in a state of flux  – locked down one day, partially open the next – and oil prices are swinging wildly with every headline. The war might feel worlds away but the economic shockwaves are already hitting everyone from all walks of life.

DPM Gan Kim Yong told Parliament plainly: "As a small and highly open economy, Singapore will not be able to insulate ourselves completely from this crisis." This geopolitical mess is going to squeeze our grocery bills, bump up transport costs and make life more expensive.

I’m already seeing petrol prices hit record high in 2026 and my Grab rides are quietly getting more expensive with every trip. I’m sure you’ve noticed it too. To think I complained about the past two GST hikes.

To understand why this conflict is sending shockwaves through the global economy, we must first understand the Strait of Hormuz. Roughly 20% of the world’s oil and natural gas shipping squeeze through this narrow waterway daily. Major producers depend on it as their primary export route and there’s simply no other adequate alternative.

The situation remains fluid. Iran has blocked vessels linked to the US or Israel, and while a ceasefire has brought partial relief, traffic through the Strait has been stopping and starting with every new development. One diplomatic statement can move oil markets by several percentage points – that's how much is riding on what happens here daily.

Feeling the pinch

Let’s get into what this actually means for your day-to-day life.

Transport – Filling up our cars already stings and it may get worse.

Essential bus operators for the elderly and disabled have seen fuel bills more than double overnight. The government has stepped in to co-fund part of their costs, but operators say it won’t be enough if the conflict drags on. DPM Gan also urged Singaporeans to take public transport over driving.

Groceries – When oil spikes, everything costs more to make and ship. Minister for Home Affairs K Shanmugam mentioned that natural gas is a key feedstock for fertilisers, and with gas supplies disrupted, fertiliser prices are rising too – meaning food crops and animal feed cost more, pushing up the prices of imported food products.

Airfreight rates between Asia and Europe have almost doubled since the conflict began, and these costs will eventually land on your supermarket receipts.

Utilities – Household electricity prices have already risen by as much as 11% since the war began and that’s just the start. DPM Gan’s message to Singaporeans: conserve energy where you can by using fans instead of air-conditioning, - Govt subsidising energy costs for businesses? Releasing CDC vouchers etc

What you can do right now

Balance your cash wisely. T-bills and fixed deposits are worth looking at for your emergency fund right now. The latest 6-month T-bill yielded 1.47% p.a. and the 1-year came in at 1.46% p.a. – not exciting, but safe and government-backed. That said, parking too much cash on the sidelines means inflation quietly eats into it. Don’t hoard, deploy smartly.

Ignore the market fluctuations. Global equities have taken a hit and recovered , but may keep fluctuating in the short-term. As Warren Buffett put it: "Look at market fluctuations as your friend rather than your enemy; profit from folly rather than participate in it." Markets recover – they always have.

Keep drip-feeding your capital. Personally, I’m still dollar-cost averaging into US tech, semiconductor stocks and diversified ETFs. When the world panics, high-quality assets go on sale. That’s exactly where you want to be – buying, not retreating. Stay the course if you’re on it.

Maximise what you have. Eligible HDB households are receiving up to S$570 in U-Save rebates as part of Budget 2026 – one and a half times the standard annual amount. The S$1 billion support package also includes CDC vouchers and cost-of-living payments. Check your eligibility and make sure you’re not leaving money on the table. Feedback: Planning your expenses can help you maximise every dollar.

Cut back where you can. This isn’t glamorous advice, but it’s practical. Take public transport over Grab where you can – surcharges are only going one way right now. Eat out at restaurants less often if you can, as food prices rise. Opt to use fans over air-conditioning, and if your electricity contract is up for renewal, compare retailers on the Open Electricity Market before the next hike lands.

A final thought 

Nobody has a crystal ball – and anyone who claims otherwise probably has something to sell you. What I do know is that the best thing you can do in uncertain times is keep your head, take care of the basics and not make panic-driven decisions you'll regret when the dust settles.

If you're feeling uncertain about where your finances stand, that's completely normal. It might just be a good time to sit down with a Financial Adviser Representative and figure out where you actually stand.
