Quick answer: Foreign exchange is part of the title chain, the Land Department expects FET certificates proving inbound foreign currency for freehold registration. Send SWIFT 5-7 business days before SPA deadlines, budget 0.5-1.5% FX spread plus wire fees, and keep every FET original for future repatriation, verify current bank rules with your lawyer.
Foreign exchange is not a footnote in a Phuket purchase, it is part of the title chain. The Land Department expects foreign buyers to prove inbound funds arrived as foreign currency converted through the banking system. That proof is the FET (Foreign Exchange Transaction) certificate. Without it, freehold registration stalls. With proper documentation from day one, the same paper trail supports repatriation of sale proceeds years later.
This guide covers THB/USD/EUR mechanics for property buyers: how FETs are issued, what banks charge, how to time transfers against SPA milestones, and how FX choices affect your all-in cost.
Why does foreign exchange matter for Thai property ownership?
The logic is straightforward: Thailand welcomes foreign investment in property, but wants funds traceable through banks. FET is the receipt. Treat each certificate like a title document, store originals, scan backups, and match every SPA payment tranche.
| Document | What it proves | When you need it |
|---|---|---|
| FET certificate | Foreign currency entered for property | Land Department transfer |
| SWIFT confirmation | Your bank sent the funds | Internal tracking; lawyer file |
| Thai bank credit note | Baht credited after conversion | Pairs with FET |
| SPA payment receipt | Developer/seller acknowledged | Milestone compliance |
| Transfer fee receipt | Government fees paid | Completion file |

How do THB, USD, and EUR flows work in practice?
| Your currency | Typical path | Watch-out |
|---|---|---|
| USD | SWIFT to Thai bank; FET in USD amount | Correspondent bank delays on large wires |
| EUR | Same; some EU banks use SEPA then SWIFT for TH | SEPA does not replace FET, must land as foreign FX in TH |
| GBP | Post-Brexit SWIFT similar to USD | UK spread varies widely by bank tier |
| AUD/SGD | Common for Asia-Pacific buyers | Time-zone cut-offs affect arrival |
| INR (LRS) | Indian banks remit USD; FET still Thai-side | Home-country LRS docs separate from Thai FET |
The baht traded roughly 34-37 per USD through much of 2024-2026, exact rates move daily. Do not underwrite a purchase assuming a favorable FX windfall; model ±3% sensitivity on total cost.
Example: $280,000 condo at 36 THB/USD ≈ 10.08M THB purchase price. A 1% worse spread on transfer costs ~$2,800, more than many lawyer quotes. Compare rates across two Thai receiving banks before committing.
What is an FET certificate, and how do you get one?
Steps to obtain FET on each tranche:
- Send SWIFT from home bank with beneficiary details exactly as SPA states
- Purpose line: “Purchase of condominium unit [address/unit]” or lawyer-approved text
- Confirm credit with Thai bank (email + phone)
- Submit FET request form with passport copy and SPA excerpt
- Collect original FET, photocopies may not suffice at Land Department
- File in chronological order matching SPA payment schedule
| FET field | Why it must be accurate |
|---|---|
| Buyer name | Must match passport and Chanote |
| Foreign currency amount | Must cover registered portion |
| Purpose | Must reference property |
| Date | Must precede transfer day |
Insider tip: If your name has middle initials, make SWIFT, SPA, passport, and FET identical. A one-letter mismatch has delayed transfers. Your lawyer should pre-align spelling before the first wire.
Multiple milestones? Each wire gets its own FET. Off-plan buyers paying 5-7 tranches over two years should maintain a labeled folder, see payment milestones off-plan Thailand.
What do banks charge, and where is money lost?
| Cost component | Typical range | Who charges |
|---|---|---|
| Outgoing SWIFT | $25-$50 per wire | Home bank |
| Correspondent/intermediary | $0-$30 | Mid-chain banks |
| Thai inbound SWIFT | 500-2,000 THB | Receiving bank |
| FX spread | 0.5-1.5% of amount | Both sides possible |
| FET issuance | Often free; sometimes 500 THB | Thai bank |
On $300,000 single transfer:
- 0.5% spread ≈ $1,500 implicit cost
- 1.5% spread ≈ $4,500 implicit cost
- Difference between a good and bad banking day: $3,000
Negotiation levers: Private banking tiers, pre-booked FX rates for large tranches, and using the same Thai bank for purchase and future rental income. Regional guides: currency transfer US buyers, currency transfer UK buyers, currency transfer EU buyers.
Red flag: A developer’s “preferred exchange booth” offers better rate than banks but no FET. Never use for purchase funds.
How should you time transfers against SPA milestones?
| SPA milestone | Timing rule | Remote buyer note |
|---|---|---|
| Reservation (1-5%) | Wire within 3 days of signing | Small amount; still request FET if foreign currency |
| SPA deposit (10-30%) | 5-7 days before SPA date | First major FET, verify all fields |
| Off-plan progress payments | Calendar reminders 10 days ahead | Series of FETs over 18-36 months |
| Pre-transfer balance | Arrive before snag sign-off | Lawyer confirms credit before you fly |
| Transfer day fees (6-7%) | Cash or same-day transfer at LD | Separate from purchase price FET logic |
Worked example, ready resale with 20% deposit, 80% at transfer:
| Step | Amount (USD) | Action date | Land date |
|---|---|---|---|
| Deposit | $56,000 (20%) | Wire day −7 | DD complete |
| FET #1 issued | n/a | Wire day −3 | File with lawyer |
| Balance | $224,000 (80%) | Wire day −7 before transfer | Snag cleared |
| FET #2 issued | n/a | Wire day −3 | Match balance |
| Transfer | Chanote registration | Day 0 | Both FETs present |

How do purchase FX flows connect to repatriation on sale?
| Exit document | Links to purchase FET? |
|---|---|
| Sale SPA | Shows new buyer and price |
| Land Department transfer (sale) | Proves disposition |
| Withholding tax receipt | May apply on seller gains, confirm with accountant |
| Original purchase FETs | Proves inbound basis |
| Outbound FET (sale) | Bank records foreign currency sent abroad |
Conservative planning: Keep every FET 10+ years. Digital scans in cloud storage; originals in fireproof folder. If you refinance, renovate with inbound foreign loans, or receive insurance payouts, ask whether those flows need separate documentation, do not mix with property FET logic without lawyer advice.
Tax on gains: do foreigners pay capital gains tax Thailand, verify current rules; this guide does not replace accounting advice.
The three currency exposures, and which ones you can manage
Buyers usually think about exchange rates once, at purchase, and then stop. There are actually three separate exposures and they behave differently.
The purchase exposure. Converting your home currency into baht to buy. On a single-payment resale this is one moment and it can be planned for. On an off-plan schedule running two years it is a series of conversions at rates nobody can forecast, which makes it a structural exposure rather than a timing decision. Forward contracts and limit orders exist for exactly this, and are worth understanding before the first instalment rather than after the third.
The income exposure. Rental income arrives in baht and your life is priced elsewhere. This one is continuous, cannot be hedged practically at the scale of a single property, and matters most to owners who depend on the income rather than reinvesting it locally. The honest response is to model the return with a meaningful adverse move and check that it still works.
The exit exposure. Sale proceeds convert back at whatever the rate is then, which may be years away. This is the one buyers never model and it can be the largest of the three in absolute terms, because it applies to the whole capital sum rather than to an annual income stream.
What you can control is the first, partially, and how much attention you pay to the other two when deciding what the investment actually needs to return.
Foreign exchange red flags checklist
- Developer requests crypto or cash baht for registered portion of price
- No FET offered after foreign-currency SWIFT credited
- Buyer name on FET differs from passport/SPA
- Purpose line blank or “general transfer” on bank records
- Third-party sender on SWIFT (must be buyer or documented gift with legal review)
- Single FET claimed for multiple unrelated wires
- Pressure to complete transfer day before FET originals arrive
- Offshore account of unknown entity, not developer escrow or lawyer client account
Where the money actually goes when you transfer
Most buyers see one number, the rate they were quoted, and never see the components underneath it. Separating them explains why two providers quoting similar rates can cost very different amounts.
The spread. The gap between the interbank rate and the rate you are given. This is the largest cost by a wide margin on a property-sized transfer, and it is invisible because it arrives embedded in the exchange rate rather than as a line item. On a purchase of a few hundred thousand dollars, a spread of a percentage point is several thousand dollars, larger than the legal fee and comparable to the buyer’s share of the transfer fee.
The sending fee is a fixed charge from your own bank. Small, and the one buyers focus on.
Intermediary charges. A SWIFT payment may route through correspondent banks, each of which can deduct a fee, which is why the amount arriving is sometimes less than the amount sent. Ask your bank to send with charges paid by you rather than deducted from the transfer, so the full sum lands.
The receiving charge is the Thai bank’s fee for handling an inward remittance, typically modest and often capped.
Two rules follow. Compare the rate you are offered against the interbank rate on the day rather than against another provider’s quote, because both may be wide. And check what actually arrives against what you sent on the first transfer, before you repeat the arrangement for the balance.
Which Thai bank should receive your property SWIFT?
| Bank factor | What to compare |
|---|---|
| FET issuance speed | 1-5 business days after credit; ask in writing |
| English service desk | Critical for remote buyers |
| FX spread on large tranches | Request quote at $100K+ thresholds |
| Branch familiarity with property | Sukhumvit/Phuket branches often faster |
| Future rental account | Same bank simplifies owner statements |
Remote opening: Some banks require in-person KYC; others accept lawyer-facilitated opening with passport copies and proof of address. Plan 2-3 weeks for account readiness before first milestone, not the day reservation is due.
If your developer insists on a specific receiving account, verify it is a corporate escrow account matching the SPA seller entity, not a personal account. Cross-border buyers from the US should also read currency transfer US buyers for home-bank cut-off times (often 4-5 p.m. Eastern for same-day processing).
How does FX differ for off-plan vs ready resale?
| Purchase type | Number of FETs | FX strategy consideration |
|---|---|---|
| Ready resale | 1-2 | Single rate lock vs market timing |
| Off-plan early buyer | 4-7 | Spread exposure across years |
| Off-plan late buyer | 2-3 | Larger tranches closer together |
| Assignment purchase | Verify prior buyer FETs | Gap = registration risk |
Assignment scenario: Buying an off-plan assignment? Confirm whether prior buyer FETs transfer with the unit or whether you must bring fresh foreign currency for the registered portion. Assignments without clean FET continuity have stalled at Land Department, lawyer review mandatory. See off-plan assignment Phuket property.
Rate hedging: Retail buyers rarely use forward contracts; practical approach is tranche timing, if baht is unusually strong against your home currency, consider accelerating a milestone payment within SPA tolerance (only after lawyer confirms no penalty).
What about rental income and ongoing FX after purchase?
| Flow type | Typical handling |
|---|---|
| STR income to Thai savings | Monthly; manager deposits net after fees |
| Quarterly repatriation | Bank form + passport; amounts under bank thresholds simpler |
| Reinvest in second unit | May need fresh inbound FET for registered portion |
| Pay management in THB | Normal local expense; no FET needed |
Discuss rental FX with the same banker who issued purchase FETs, they already know your profile. Tax withholding on rental income (often cited around 15% for foreign landlords, confirm with accountant) affects net repatriation amount; see Thailand property tax foreigners for overview.

Frequently Asked Questions
An FET (Foreign Exchange Transaction) certificate is issued by a Thai bank when foreign currency enters Thailand for property purchase. It proves the inbound flow and is required for foreign freehold registration at the Land Department, and for documenting future repatriation if you sell.
Purchase contracts are denominated in THB at the Land Department. You send USD or EUR via SWIFT; the Thai bank converts to baht and issues FET showing the original foreign currency amount. You cannot register freehold using undocumented baht from informal sources.
Expect $25-$50 outgoing SWIFT fee from your home bank, 0.5-1.5% FX spread on conversion, and 500-2,000 THB inbound fee at the Thai bank. On $300,000, spread timing alone can differ by $2,000-$4,000 between banks.
Yes, each inbound foreign-currency tranche should generate its own FET. Off-plan buyers with five milestones should file five FET originals. Missing FETs complicate transfer day and weaken repatriation documentation on exit.
Initiate SWIFT 5-7 business days before the contractual due date. Same-day urgency fails when correspondent banks delay. Align final tranche arrival 3-5 days before Land Department transfer.
Documented property flows are handled differently from casual transfers. Keep all purchase FETs, sale agreement, and transfer documents, your Thai bank uses them to process outbound FX on exit. Verify current rules with your banker and accountant.
