Is SuperRich the Best Exchange in Bangkok? An Honest Answer (2026)

2026-04-247 min read

The Advice Everyone Gives (and Nobody Questions)

Search "best exchange Bangkok" and you will get the same answer a hundred times: go to SuperRich. Green logo, Rajdamri Road, best rates in the city.

And to be fair, that advice is not wrong. SuperRich does post the best walk-in exchange rates in Bangkok -- consistently within 0.1-0.3% of the interbank mid-market rate for major currencies. No other storefront exchange in Thailand comes closer.

But "best rate" and "best choice for you" are not the same thing. A rate board does not account for the 35-minute queue at noon, the BTS fare from your hotel, or the fact that you are only exchanging $150 and the shop around the corner is almost as good.

After years of tracking Bangkok exchange rates and helping thousands of travelers with our calculator, here is the honest breakdown of when SuperRich is genuinely your best option -- and when it is not.

SuperRich Rates vs the Competition: Actual Numbers

Let us put real numbers on the comparison instead of vague percentages. These are representative USD-to-THB rates -- not live, but the relative gaps are consistent.

For every $100 USD exchanged: - SuperRich (Green or Orange): 3,420 THB - Vasu Exchange (Sukhumvit): 3,415 THB -- 5 THB less - SIA Money Exchange (Siam): 3,405 THB -- 15 THB less - Central World mall bank counter: 3,375 THB -- 45 THB less - Airport counter (Suvarnabhumi): 3,310 THB -- 110 THB less - Hotel front desk: 3,280 THB -- 140 THB less

Scale that up: - $300 exchanged: SuperRich saves 15 THB vs Vasu, 45 THB vs SIA, 135 THB vs mall bank, 330 THB vs airport - $500 exchanged: SuperRich saves 25 THB vs Vasu, 75 THB vs SIA, 225 THB vs mall bank, 550 THB vs airport - $1,000 exchanged: SuperRich saves 50 THB vs Vasu, 150 THB vs SIA, 450 THB vs mall bank, 1,100 THB vs airport

The pattern is clear: SuperRich beats everyone. But the margin over Vasu is tiny, and the margin over SIA only becomes meaningful above $500.

The Hidden Costs That Change the Math

Rates alone do not tell the full story. Here is what you actually spend to use SuperRich.

Transport cost (round trip to Rajdamri): - From Asok/Nana BTS: 66 THB + 25 min each way - From Khao San Road: 100-150 THB by bus/boat + BTS, 45 min each way - From Silom/Sathorn: 33 THB + 10 min each way - From Siam: 0 THB, 8-min walk

Queue time: - Before 10:30am: 5-10 minutes - 10:30am-3pm weekdays: 20-35 minutes - Weekends any time: 25-45 minutes - Grand SuperRich next door: usually 30-50% shorter queue - Central World branch: rarely more than 10 minutes

Opportunity cost: What else could you do with that 60-90 minutes? In Bangkok, that is a temple visit, a street food crawl, or a Thai massage.

Real example -- staying near Asok, exchanging $400: - SuperRich savings vs Vasu: 20 THB - BTS round trip: 66 THB - Queue time: 20 min - Travel time: 50 min - Net result: you LOSE 46 THB and 70 minutes

Another example -- staying near Siam, exchanging $800: - SuperRich savings vs SIA: 120 THB - Transport: 0 THB (walking distance) - Queue: 10 min (went at 9:30am) - Net result: you SAVE 120 THB in 18 minutes total

When SuperRich IS Your Best Option

SuperRich genuinely wins in these situations:

1. You are staying in the Siam-Ratchadamri-Chit Lom area. Transport cost is zero. Even for $200, the savings over mall counters (90 THB) justify the 10-minute walk. For a detailed guide to all exchange options in this neighborhood, see our Siam area exchange guide.

2. You are exchanging $500 or more. At this volume, SuperRich saves 75+ THB over SIA and 225+ THB over mall counters. Even a BTS ride from Asok (66 THB round trip) leaves you ahead.

3. You are exchanging an uncommon currency. SuperRich handles TWD, KRW, SGD, MYR, and other currencies that smaller shops either refuse or quote poorly on. For niche currencies, SuperRich often has the only reasonable rate in Bangkok.

4. Your schedule already takes you past Rajdamri. If you are visiting Central World, Erawan Shrine, or Lumpini Park, the detour to SuperRich adds 5 minutes. Zero marginal cost means any savings are pure profit.

5. You are doing a single large exchange for a long trip. Exchanging once at the best rate beats multiple small exchanges at okay rates. Time efficiency favors one trip to SuperRich over three trips to mediocre shops.

When SuperRich Is NOT Worth It

Here is where the "always go to SuperRich" advice falls apart:

1. You are staying on Sukhumvit and exchanging under $500. Vasu Exchange on Soi 7/1 is within 0.1-0.2% of SuperRich rates. It is a 10-minute walk from Asok BTS, has shorter queues, and costs zero in transport. The savings at SuperRich ($25 THB on $500) do not cover the 66 THB BTS fare. Check our Asok exchange guide for the full comparison.

2. You are exchanging under $200 anywhere in Bangkok. The absolute savings are small: $200 at SuperRich vs SIA saves about 30 THB (under $1). At that level, go to whichever exchange is closest to where you already are.

3. It is peak hours and you have limited time. Spending 35 minutes in a SuperRich queue to save 50 THB means you are earning about 86 THB per hour standing in line. Your vacation time is worth more than that.

4. You need money on a Sunday evening or holiday. SuperRich Rajdamri is open Sundays but with heavy crowds. Grand SuperRich is closed. The Central World branch follows mall hours (open until 10pm, including Sundays) -- that is usually a better Sunday option.

5. You just landed and need cash now. Exchange a small amount at the airport (enough for transport and SIM) and do the rest later. The airport-vs-city math is covered in detail in our airport exchange comparison.

The Better Question: What Is the Best Exchange for YOUR Situation?

The right exchange shop depends on three variables: how much you are exchanging, where you are, and how much free time you have. Here is a quick decision matrix.

Staying near Siam + any amount = SuperRich (walk 8 min) Staying near Asok + under $500 = Vasu (walk 10 min) Staying near Asok + over $500 = SuperRich (BTS 25 min, net positive) Staying near Khao San + under $300 = local exchange shop (save the trip) Staying near Khao San + over $300 = SuperRich (boat + BTS, 45 min) Staying near Silom + any amount = SuperRich (BTS 10 min, very close) Just arrived at airport + under $100 = airport counter Just arrived at airport + over $200 = airport for small amount, SuperRich tomorrow

Or skip the matrix entirely. Our exchange calculator takes your currency, amount, and location, then tells you exactly which shop gives you the most baht after transport costs. It takes 30 seconds and removes the guesswork.

What Makes SuperRich Rates So Good (and Will It Last)?

Understanding why SuperRich offers better rates helps you evaluate alternatives.

SuperRich operates on volume, not margin. The Rajdamri flagship alone processes millions of dollars in daily transactions. At 0.1-0.3% spread, that tiny margin multiplied by enormous volume produces sustainable profit. Traditional exchange counters at airports and hotels process far less volume and compensate with 3-6% spreads.

SuperRich is also family-owned and has been operating since 1965. No franchise fees, no corporate overhead -- just decades of reputation driving foot traffic. The two brands (Green and Orange) are run by different family members but share the same business model.

Will this last? Probably. The model is robust because it is self-reinforcing: good rates attract volume, volume funds good rates. The bigger threat to cash exchange is not a rival shop but the gradual shift to digital payments. For now, cash is still king for Bangkok street food, markets, and taxis -- so SuperRich will remain relevant for years to come.
