How money changers actually make money in 2026 (the spread, explained simply)
⚡ 30-Second Answer: Money changers earn from ①the spread between bid/ask (2-8% margin) — their main income, ②flat fees of ¥500-1,500 per transaction, and ③FX inventory hedge gains. "No fee" booths hide 5-8% spreads — you end up -7-10% worse off. Wise/Revolut operates at mid +0.5%, less than half the cost of physical changers.

Money changers profit from the "spread" — the gap between the rate they buy currency from you and the rate they sell currency to you. A typical 2–3% spread on a $1,000 transaction yields about $20–$30 of margin per trade, with the customer paying that gap as the implicit cost of the exchange. Understanding the spread is the key to evaluating every exchange offer; the mechanics are simpler than they seem.
TL;DR
- Spread = sell rate − buy rate (the gap between what you receive vs what they sell back to you).
- Typical spread: 2–3% on common currencies; 5%+ on rare ones.
- Shop profit per trade: the spread × the volume traded.
- Tighter spread = better for customers: street shops compete on this; banks and airports don't.
What's the spread?
Every shop displays two columns:
| Column | Meaning |
|---|---|
| WE BUY | What they pay you when you sell foreign cash to them (lower number) |
| WE SELL | What they charge you when you buy foreign cash from them (higher number) |
The gap between these two — the spread — is how the shop makes money.
For USD on a typical day (illustrative — check the live rate, only World Currency Shop is live-tracked here):
- WE BUY: roughly 1.5–2% below the mid-market rate
- WE SELL: roughly 1.5–2% above the mid-market rate
- Spread: roughly 3–4% total
So if one customer brings $1,000 USD cash to sell and another customer buys $1,000, the shop pockets the difference between the two rates — a few percent of the amount — as profit on the round-trip. Rates are indicative and move daily, so always check the live board before walking in.
The number to remember: for a typical Tokyo street exchange shop, the spread is 2–3% on common currencies (USD, EUR, CNY) and 4–6% on rarer ones (THB, VND, IDR) — reflecting both inventory cost and demand patterns.
Why does the spread vary by shop?
Three factors:
Competition density
Where many shops cluster (Shinjuku West, Ginza), spreads compress to 1–2%. Where shops are isolated (airports, hotels, rural areas), spreads stay at 4–6%.
Cost structure
Higher rent, staff cost, security overhead = wider spread. Airport rents are highest; competitive Tokyo retail rents are moderate; pawn-shop windows are lowest cost.
Currency rarity
Common currencies (USD, EUR) trade frequently — inventory turns over fast, supporting tight spreads. Rare currencies (VND, IDR) sit in inventory longer; the spread compensates.
Why does the best Tokyo shop get so close to the mid-market rate?
The top central-Tokyo shops publish a buy rate just slightly below mid-market — never above it, because the shop always keeps the spread — but the gap can be remarkably thin:
- Tourist cash flow is desirable inventory; they re-sell to outbound travelers, so they can afford a thin buy-side margin
- Competition compresses margins on USD/EUR specifically
- Aggressive pricing wins repeat tourist customers
This shows up at downtown specialist counters — Dollar Ranger, World Currency Shop, Daikoku and other independents — where the USD buy rate typically lands somewhere around mid −1% to −2.5%, varying by shop and day. (World Currency Shop, the one operator we live-track, currently sits near mid −2%.) The exact figure moves daily, so treat any single number you see quoted as indicative and check the live rate.
The math still works for the shop: the buy rate sits a fraction below mid-market and the SELL rate sits above it, so the shop captures the spread on both sides.
What this means for your trip
- ✅ Look for spreads under 2% at the best Tokyo shops.
- ✅ Ask about "we buy" rate if you're selling foreign cash; that's the column that matters.
- ✅ Compare against mid-market before walking in.
- ⚠️ Spreads above 4% at airports and hotels — expensive.
Frequently asked questions
Why don't shops just match mid-market exactly?
Margin is necessary for them to operate. Even shops with the tightest spreads (1.5%) cover their cost-of-goods, rent, and staff from that thin margin.
Do online services like Wise have spreads?
No — Wise charges a flat fee (0.41–0.6%) on top of the mid-market rate. Spread = 0%; total cost = transparent fee.
What's the spread on Pocket Change?
Pocket Change machines convert foreign coins/bills into e-money at roughly 1–2% below mid-market — same scale as mid-tier exchange shops.
Are spreads regulated in Japan?
No regulatory spread cap. Shops self-regulate via competition. Disclosure (showing both buy and sell rates) is required; maximum spread is not.
