Southeast Asian account histories
Six account histories join the atlas, from Melaka’s calains and Aceh’s mas to Java’s fiscal rupees and Indonesia’s competing wartime money. Four qualified ancestry connections and earlier Vietnamese continuity add depth without turning later absorptions into founding parents.

New account histories
| Account history | What establishes its use |
|---|---|
| Netherlands Indies guilder | Before the 1942 occupation, the Netherlands Indies used a guilder currency issued by its government and De Javasche Bank, linked to but distinct from the Netherlands currency. |
| Japanese occupation gulden / rupiah in Indonesia | Japanese occupation money entered use in 1942; in 1943 the authorities ordered prewar currency surrendered. Old Indies money was nevertheless hoarded while transactions increasingly used the depreciating occupation currency. |
| Java rupee accounting | Raffles reports cash revenue for Java in 1814–1815 exceeding 6.5 million rupees. His revenue instructions also state collectors’ salaries and treasury remittances in rupees. These are account obligations, not merely descriptions of rupee coins. |
| Javanese picis / cash accounting | The 1358 Ferry Charter assesses an annual festival payment of 400 cash for each ferryman. This is a dated obligation in the Javanese picis system. |
| Melaka calain–cash accounting | Pires’ account, written in 1512–1515 and quoted in Gianno’s preprint, says merchandise at Melaka was priced in calains and paid in tin or gold; 100 cash made a calain. This supports a local account unit, provisionally qualified because the edition itself was not inspected. |
| Acehnese mas–tael accounting | During Dampier’s 1688–1689 visits to Aceh, rice was priced by the mas (his Mess): one bought around 14–15 bamboo measures in plenty, but only 3–4 in scarcity. He reckons 16 mas to a tael; cash rates, coin weights and Spanish-dollar prices varied separately. |
Connections and their limits
Japanese occupation gulden / rupiah in Indonesia → Indonesian rupiah
Qualified ancestry
Indonesia’s Law 19/1946 converted banked Japanese money into ORI at 50:1 in Java and Madura and 100:1 elsewhere, and prescribed payment of existing debts in Republican money. The conversion is explicit; its placement in the present rupiah profile remains qualified pending the full 1950 settlement review.

Netherlands Indies guilder → Indonesian rupiah
Qualified ancestry
Article 4 of Law 19/1946 carried unpaid obligations incurred before 1 January 1943 into Republican money at one old legal rupiah to one ORI. Read with the Indies currency history, it supports a qualified colonial-account input at ORI’s introduction; it is not a claim that every old debt or region received the cash exchange rate.

Old Javanese masa–suwarna accounting → Javanese picis / cash accounting
Qualified ancestry
Old Javanese legal adaptations express fines or payments first in indigenous ma–su–ku terms and also in cash amounts. Wicks connects this re-expression of values with the move to picis reckoning around 1300. The account succession is qualified: the legal glosses are not precisely dated, and 1296–1358 bounds the dated evidence rather than an exact conversion decree.
Indochinese piastre → Vietnamese đồng
Qualified ancestry
Vietnamese financial money developed in 1946 to displace Indochinese piastres and could settle taxes and debts alongside them. The link is a qualified regional account succession, inferred from replacement and fiscal use together; neither a common name nor a one-to-one peg is its sole basis. Later northern continuity is retained within the current đồng profile.

The đồng before national unification
Vietnamese đồng now includes the financial and northern line before 1978, with an explicit qualification. No extra currency is created for a rescaling. The separate southern input remains a later historical conversion.
Depth measured consistently
Both releases are calculated with the corrected founding-ancestry rule. At or before 1500, coverage changes from 95 to 96 endpoint codes including qualified paths; strict coverage remains 34. The additional code is VND. These totals describe the inherited endpoint register, not the completeness of Southeast Asian monetary history.
| Endpoint | Previous earliest witness | Current earliest witness |
|---|---|---|
| IDR | 1946 | 1942 · qualified path |
| VND | 1978 | AD 894 · qualified path |
The older Javanese branch also gains a qualified masa-to-picis connection. It does not yet establish a path to the modern rupiah. Unconnected histories remain valuable evidence of money in use.
Work still open
- Indonesia: Java rupee → Indies guilder. Find the 1817 rules converting rents, treasury balances and outstanding rupee contracts. Minted replacements alone are insufficient.
- Indonesia: Earlier VOC and local gulden accounts. Read regional ledgers and the relevant monetary ordinances before extending the Indies profile back to VOC accounting or drawing a Dutch-guilder parent.
- Indonesia: ORI, NICA and the 1950 settlement. Verify the complete balance/debt conversion schedules and regional ORIDA rates. Preserve ORI as an early national epoch for now; no new species for a note issue.
- Java and Bali: Picis transmission and earlier local units. Date the legal glosses; check original charter editions and cross-island debt conversions before connecting Javanese cash to Balinese pisis, or imported Chinese coins to a Chinese account parent.
- Malay Peninsula: Melaka calain and later regional accounts. Verify Pires p. 275 directly; examine Portuguese conversion and later Johor/Kedah/Patani contracts. Shared tin, mas and tael names do not establish descent.
- Aceh: Mas–tael before and after Dampier. Inspect dated court contracts, VOC debt records and colonial settlement schedules; the market value of a Spanish dollar does not make it the parent of the mas.
- Vietnam: Earlier northern continuity and regional financial notes. Check the 1951 decree and account-conversion instructions against regional notes; verify the exact 1946 and 1954 piastre obligations. Keep the current northern association and founding link qualified.
- Mainland Southeast Asia: Nguyễn quan, Cambodian bat, Lao nen and older Burmese kyat. Seek tax, court and treasury conversion records into piastre/rupee/kip systems. Preserve the older disconnected accounts; do not infer their extinction or fabricate a modern connection.
- Philippines and Timor: Local accounts beyond the peso and adopted currencies. Distinguish dated local debt and tribute units from gold pieces, barter goods and foreign-coin circulation. The Laguna debt alone does not connect to the Philippine peso.
Coin circulation, matching names and shared metal standards do not establish ancestry by themselves. A gap is neither proof of independent invention nor proof that a monetary family died out.
