100 SGD to Thai Baht: Live Rates and Exchange Tips for Travelers

If you’re heading from Singapore to Thailand, the exchange rate is probably the last thing you check before packing — and one of the first you’ll want to understand on the ground. Converting 100 SGD today nets you roughly 2,518 THB at the mid-market rate, but the provider you choose and where you exchange can shift that number by 50 baht or more. This guide lays out the current rates, the providers that actually deliver, and the travel-tested tips that HSBC and seasoned Bangkok visitors swear by.

100 SGD to THB (XE): 2,518.52 THB · Rate per 1 SGD (XE): 25.1852 THB · 100 SGD to THB (RIA): 2,518.62 THB · 1 SGD to THB (RIA): 25.1862 THB · Common conversion: 10 SGD: 251.86 THB

The table below summarizes what you get from seven major providers when converting 100 SGD, ranging from mid-market benchmarks to specific transfer services.

How much is $1 SGD in Thai?

The short answer: roughly 25.19 THB per Singapore dollar as of mid-April 2026. That figure represents the mid-market rate — the honest midpoint between what banks pay when they buy SGD and what they charge when they sell THB. XE.com lists it as 25.1852 THB per SGD (Xe.com (currency converter authority)), while Ria Money Transfer sits just a hair higher at 25.1862 THB (Ria (remittance rate comparison)). The consistency across major platforms suggests the true mid-market rate genuinely clusters around 25 THB per SGD.

Current rate details

What you actually receive depends entirely on which service you use. Wise quotes 25.171 THB per SGD for 100 SGD, translating to 2,517.10 THB total (Wise (mid-market rate source)). Revolut comes in at 25.0104 THB per SGD, delivering 2,501.04 THB for 100 SGD — roughly 17 baht less than the XE mid-market (Revolut (travel fintech provider)). Instarem sits between the two at 25.1436 THB per SGD (Instarem (live conversion data)).

100 SGD equivalent

At the current mid-market rate, 100 SGD converts to approximately 2,518 THB. That buys a decent street food budget for two to three days in Bangkok — roughly 25 meals at local markets, or a mix of transport and meals if you’re pacing yourself. The spread between providers adds up fast: choose Remitly’s special rate and you’ll receive only 2,463 THB, a 55-baht penalty on a single conversion.

Historical trends

Wise’s 30-day data shows the rate has ranged from a high of 25.5898 THB per SGD to a low of 25.1591 THB per SGD, with an average of 25.3950 (Wise (historical trend data)). That 0.43 baht swing matters for larger transfers — convert 5,000 SGD and you’re looking at roughly 2,150 baht in difference depending on timing. The rate has dipped slightly since the March high, suggesting a modest softening of the Singapore dollar against the baht.

The implication: timing your exchange within a 30-day window can yield meaningful differences, but waiting for the absolute peak is impractical for most travelers. A weekday morning check on XE or Wise gives you enough information to act without chasing the perfect rate indefinitely.

Is it better to change Thai baht in Singapore or Thailand?

The conventional wisdom among Bangkok visitors holds that Singapore offers better exchange rates than Thailand itself — even when converting twice. “Singapore has always been known as the best place to exchange money even if you have to change twice,” noted one TripAdvisor contributor with on-the-ground experience (TripAdvisor Forum (traveler consensus)). That said, the fintech revolution has complicated this picture: Revolut, Wise, and Instarem now deliver rates that rival or beat traditional money changers in Singapore.

Exchange options in Singapore

Your options break into three tiers: bank branches, dedicated money changers, and fintech apps. HSBC advises exchanging during weekday bank hours for optimal rates, noting that weekends consistently yield the worst deals (HSBC Singapore (banking guidance)). Dedicated money changers in downtown Singapore — particularly in the Bugis and Raffles Place areas — compete aggressively on SGD-THB, and some advertise rates within 0.1% of the mid-market.

Thailand airport vs city rates

If you arrive in Bangkok without Thai baht, the airport exchange counter is a trap. “Hotels often offer less favourable rates compared to banks and booths,” noted the SingaporeBoleh9 travel blog (SingaporeBoleh9 (travel advice blog)), and airports perform even worse than hotels. Superrich Thailand and competing currency booths in central Bangkok — particularly on Sukhumvit Road near Nana and Asoke stations — post rates competitive with Singapore money changers. Legend Travel Group confirms that banks offer better rates than airports or hotels across the board (Legend Travel (regional budget guide)).

ATM and card alternatives

ATMs in Bangkok accept most Singapore-issued cards and dispense THB directly. The catches: Thai banks typically charge a 150–220 THB flat fee per withdrawal, and your home bank may add a foreign transaction fee (often 1–3%). SingaporeBoleh9 notes that ATMs, banks, and booths offer varying rates and fees across Thailand (SingaporeBoleh9 (travel advice blog)). For amounts under 2,000 THB, this flat fee makes ATM withdrawal poor value — you’re better off pre-loading a multi-currency card like Revolut or using Wise.

The catch: Revolut’s 25.0104 THB per SGD beats most Thai exchange counters, but only if your home bank doesn’t charge foreign transaction fees on card purchases abroad. Check your card’s fee schedule before assuming the app is always the winner.

Why is SGD dropping against THB?

The Singapore dollar has weakened modestly against the Thai baht over the past year, slipping from the 25.58 high in March 2026 down toward 25.16 in recent weeks — a roughly 1.6% softening according to Wise’s 30-day data (Wise (30-day rate tracking)). Several interlocking factors drive this movement.

Recent trends

The SGD-THB pair reflects diverging monetary policy signals from the Monetary Authority of Singapore (MAS) and Bank of Thailand (BOT). Thailand’s tourism recovery — which contributes roughly 12% of GDP — has strengthened demand for baht, while Singapore’s export-heavy economy faces headwinds from slower electronics demand cycles. The SingaporeBoleh9 blog recorded typical rates of 24–25 THB per SGD as recently as October 2023 (SingaporeBoleh9 (historical rate context)), suggesting the pair has been range-bound rather than in a clear trend.

Economic factors

Interest rate differentials between Singapore and Thailand influence the pair. When Thai domestic rates rise to combat inflation or stabilize the baht, the differential narrows and SGD weakens relatively. BOT’s rate decisions — influenced by tourism receipts, food price inflation, and domestic consumption — ripple into the SGD-THB cross. Singapore’s peg to trade-weighted baskets means MAS movements are less directly correlated to the THB pair than one might expect, but global risk sentiment matters: periods of risk-off typically strengthen SGD as a safe-haven regional currency.

Forecast outlook

No authoritative body publishes formal SGD-THB forecasts at the retail traveler level. The 30-day range of 25.16–25.59 gives a reasonable band: unless Thailand’s tourism surges unexpectedly or MAS raises rates sharply, expect the pair to remain in the 25.0–25.6 range through mid-2026. For travelers converting less than 2,000 SGD, the timing cost of waiting for a better rate rarely exceeds the baht savings from perfect execution.

What this means: if your trip is in the next 3–6 months, lock in a rate today rather than gambling on a further softening. The 50 baht you might save by waiting is worth less than the certainty of a known budget.

How strong is the Singdollar against the ringgit, yen, thai baht and yuan?

Singaporeans often gauge their dollar’s purchasing power across Southeast Asia and East Asia. Against the Thai baht, the Singdollar holds reasonably strong — roughly 25 THB per SGD places Bangkok at a favorable cost point for Singapore visitors, where daily budgets of 1,000–2,500 THB stretch further than equivalent SGD spending at home.

SGD vs THB specifics

The baht has strengthened against the SGD over the past decade from historical highs of THB 28–30 per SGD in earlier periods to the current 25.1–25.6 band. This 10–15% improvement in Thai purchasing power makes Singapore trips to Bangkok, Chiang Mai, and the islands significantly more affordable in real terms for SGD holders. The Legend Travel Group notes that Thailand’s daily budget can range from $20–$120 depending on style, with SGD holders sitting comfortably in the mid-range (Legend Travel (Southeast Asia budget guide)).

Regional currency strength

Compared to other regional neighbors: SGD to MYR sits around 3.5–3.6 (SGD buys less ringgit than it did three years ago), SGD to JPY has swung widely from 90 to 110 depending on yen carry trade dynamics, and SGD to CNY holds near 5.1–5.3. The baht ranks as one of the stronger regional currencies from a Singapore travel perspective — your SGD goes further in Bangkok than in Kuala Lumpur or Tokyo, though not as far as it once did.

Key drivers

Singapore’s Monetary Authority manages SGD through a trade-weighted basket, insulating it from the extreme swings that affect tourism-dependent baht. Thailand’s BOT, meanwhile, allows more two-way movement, which can create opportunities but also risk. For Singapore-Thailand travel specifically, the current rate represents a fair to favorable window — not the cheapest historically, but stable enough to budget with confidence.

The trade-off: SGD holders enjoy meaningful purchasing power in Thailand today, but the baht’s appreciation over the past decade means the “cheap Thailand” of 2015–2018 no longer applies at current rates. Budget accordingly and avoid the trap of assuming everything is discounted in baht.

Is Singapore as cheap as Thailand?

Short answer: no. Singapore ranks among the most expensive cities in Southeast Asia, while Thailand spans a wide cost spectrum from budget Bangkok street markets to resort-heavy island chains. The currency exchange rate doesn’t change this fundamental gap — it simply determines how far your Singapore dollars stretch when you arrive.

Cost of living breakdown

Singapore’s food and transport costs dwarf Thailand’s across every category. A hawker meal in Singapore runs SGD 4–8; a comparable Thai street dish in Bangkok costs THB 35–80 (roughly SGD 1.40–3.20 at current rates). Public transport in Singapore starts at SGD 0.92 per trip; Bangkok’s BTS skytrain charges THB 16–59 (roughly SGD 0.64–2.35). The gap closes for imported goods — electronics, branded clothing, and alcohol cost similar amounts in both currencies — but local services and food heavily favor Thailand.

Travel expenses

Flights from Singapore to Bangkok run SGD 80–200 roundtrip on budget carriers, making short trips feasible on a weekend budget. Accommodation in Bangkok ranges from THB 800–1,500 for a clean hostel room to THB 3,000–8,000 for a four-star hotel — SGD 32–60 and SGD 120–320 respectively. The same hotel tier in Singapore costs SGD 150–400, making Thailand accommodation roughly 4× cheaper in SGD-equivalent terms.

Currency impact on budgets

For a Singapore visitor, the 25.19 THB per SGD rate means 100 SGD converts to 2,518 THB — enough for 2–3 nights of mid-range accommodation, 15–25 street food meals, and a week of local transport in Bangkok. The same 100 SGD buys roughly 3–4 days of basic living expenses in Singapore. The SGD-THB rate amplifies Thailand’s cost advantage, making even modest SGD savings translate to meaningful baht spending power.

How to get the best SGD to THB exchange rate

Converting Singapore dollars to Thai baht doesn’t require special skills, but a few deliberate choices separate travelers who get 2,518 THB for their 100 SGD from those who walk away with 2,463 THB. Here’s the practical sequence.

1. Check the mid-market rate first. Open XE.com or Wise’s currency converter before doing anything else. The mid-market rate (around 25.1852 THB per SGD) is your benchmark — every provider will be worse, but you want to know how much worse. Write down the number.
2. Download Revolut or Wise. Both apps quote rates within 0.1% of the XE mid-market. Revolut charges no foreign transaction fees on its metal card for most users (Revolut (travel fintech provider)). Wise offers transparent fees with no hidden charges (Wise (mid-market rate source)). Set up the account and load SGD before you leave Singapore.
3. Skip the airport exchange. Bangkok’s Suvarnabhumi Airport exchange counters consistently post rates 1–3% below the mid-market. “Avoid exchanging at hotels due to poor rates” is the cardinal rule from SingaporeBoleh9’s travel guide (SingaporeBoleh9 (travel advice blog)), and the same applies doubly to airports.
4. Use bank hours if exchanging cash. HSBC’s travel FX tips are clear: weekday hours yield the best rates, while weekends deliver the worst (HSBC Singapore (banking guidance)). If you must exchange cash in Thailand, visit a bank branch between Monday and Thursday mornings.
5. Keep small denominations. Thai merchants — especially market vendors and temple donation boxes — frequently cannot make change for 1,000 THB notes. Request 100 THB and 500 THB notes when exchanging, and carry at least 500 THB in small bills before heading to street markets.
6. Use digital payments where accepted. Grab (Southeast Asia’s ride-hailing and delivery platform), convenience stores, and modern malls accept cards and QR payments seamlessly in urban Bangkok and major resort areas. Legend Travel Group endorses digital payments via Grab and Wise in urban Thailand (Legend Travel (Southeast Asia budget guide)), reducing your cash needs and the associated exchange costs.

What real travelers and experts say
