Reference notes for THB/JPY
When you typically see THB/JPY
Reverse of jpy-to-thb. The largest cohort is Thai-domiciled receivers of JPY income: Thai contractors and freelancers paid by Japanese clients, Thai exporters shipping to Japan (rice, processed seafood, electronics components for Japanese assembly plants in Thailand), Thai banks settling JPY-denominated trade finance. Thai individuals with Japanese-yen savings or investments translate periodically for personal records. A smaller flow: Thai students at Japanese universities tracking JPY-priced tuition and living costs against their THB-funded budgets.
How THB/JPY behaves in accounting
From the Thai accounting side, Bank of Thailand reference rates apply; not currently implemented. From the Japan side recording a THB receipt, Mizuho TTM (or MUFG/SMBC) on the receipt date is the conventional reference. Mizuho publishes THB/JPY directly. Volatility tracks the inverse of jpy-to-thb — same market, opposite direction. For Thai contractors invoiced monthly in JPY, prior-month-end is a common simplification on the Thai side. For Japanese counterparties recording outgoing THB payments, transaction-date TTS (since the bank is selling THB to the customer) is conventional.
Common conversion mistakes for THB/JPY
Using yesterday's TTM when the actual transfer settled today, because the wire was initiated yesterday. Banks publish one TTM per business day; the rate to record is the rate of the date money actually moved, not the date the instruction was given. Second: ignoring the small but persistent gap between TTS and TTB on this pair — Mizuho's spread on THB is wider than on USD or EUR because the volume is thinner. Recording a TTS transaction at TTM understates the cost by roughly 1 yen per 100 baht. Third: relying on a Thai-bank-quoted JPY/THB rate at the moment of conversion and then comparing it to Mizuho TTM at end of month for explanation. Thai banks quote against their own published reference and add markup; the two numbers will not match and the difference is the bank's spread, not a calculation error.
What Zenrate stores for THB/JPY
Live conversion via exchangerate-api.com (USD-base, cross-rated). Twelve-hour cache. Historical: Mizuho THB/JPY via dbFetcher/edgeFunction (note: stored as JPY-per-THB in Mizuho's format; the rate-source code handles direction). ECB via Frankfurter (cross-rated through EUR). All six rate policies apply. Prior-month-average iterates Mizuho business days; relatively dense data because Tokyo business calendar is more permissive than Bangkok's.
