Cash, cards and ATMs in Bali: what the rupiah rules require

Cards work in Denpasar's hotels and larger restaurants, but the rule that shapes your spending is not about cards at all. Bank Indonesia requires that transactions inside Indonesia be settled in rupiah, and that businesses price goods and services only in rupiah, which makes a villa rate card printed in Australian dollars a departure from the regulation rather than a courtesy. Warungs, markets, temple donation boxes, parking attendants and most small transport in Bali run on cash, so you will carry notes even on a card-heavy trip. The decision that actually costs people money is where they get that cash: Bank Indonesia licenses non-bank money changers company by company and publishes every licence, and a shop front with a chalkboard rate and no licence sits outside that system entirely. Do not plan around a per-withdrawal ATM figure you read elsewhere, because those limits belong to your own bank and to the machine's operator.

Why rupiah, by law

Bank Indonesia requires every cash and non-cash transaction within the territory of the Republic of Indonesia to be conducted in rupiah, and the obligation falls on every party, individual or corporate. The instrument is Peraturan Bank Indonesia Nomor 17/3/PBI/2015 tentang Kewajiban Penggunaan Rupiah di Wilayah Negara Kesatuan Republik Indonesia, dated 31 March 2015 (checked 16 September 2026). The same regulation adds a second duty that visitors feel more directly: businesses must display prices for goods and services in rupiah only.

The exemptions are narrow and none of them describes a holiday. The regulation carves out certain state budget transactions, international trade transactions, foreign currency bank deposits, international financing transactions, foreign currency business activities carried on by banks under the banking law, government securities issued in foreign currency, and other transactions expressly permitted by law. Paying a Seminyak restaurant is not on that list.

Sanctions are split by transaction type, which is worth knowing because it explains why the rule is enforced unevenly. Breaching the rupiah obligation in a cash transaction attracts criminal penalties under Law No. 7 of 2011 on Currency; breaching it in a non-cash transaction attracts written warnings, an administrative fine of up to 1 per cent of transaction value capped at IDR 1,000,000,000, and exclusion from payment system arrangements, while a pricing breach draws a written warning (same regulation page, checked 16 September 2026).

There is a matching rule pointing the other way, and it is useful when a driver waves your notes away. Bank Indonesia's Pengelolaan Uang Rupiah page states that the public may not refuse payment made in money issued by Bank Indonesia, under Law No. 7 of 2011, which also gives the central bank sole authority over planning, printing, issuing, distributing, withdrawing and destroying rupiah (checked 16 September 2026). Printing is done by the state enterprise Perum Peruri.

Which notes are current

Bank Indonesia currently pictures seven banknote denominations on its own currency gallery, and two complete series of those seven circulate at the same time. The 2022 emission (Tahun Emisi 2022) and the 2016 emission (Tahun Emisi 2016) both run from Rp1,000 to Rp100,000, alongside 2016 emission coins of Rp100, Rp200, Rp500 and Rp1,000 (Gambar Uang, checked 16 September 2026). Receiving two visibly different Rp50,000 notes in a week is normal, not a sign that one is fake or expired.

The table below sets out what is in circulation and what has actually been taken out of it, using Bank Indonesia's own currency gallery and its withdrawn-money list.

The newest Rp100,000 is the note you will see most at a bank counter, and it is easy to identify. Bank Indonesia's detail page gives the 2022 emission Rp100,000 as issued on 17 August 2022, measuring 151 by 65 mm, dominant colour red, with Soekarno and Mohammad Hatta on the front as the proclamators of Indonesian independence (Gambar Uang, Detail Uang, checked 16 September 2026).

Where cards actually work

Card acceptance in Bali tracks the size and formality of the business rather than the postcode. International-brand hotels, larger restaurants, supermarkets, chain pharmacies and the bigger dive and surf operators generally take cards; single-room warungs, market stalls, roadside fruit sellers, parking attendants and small transport generally do not. That split is the reason a card-only plan fails within a day, even in Denpasar.

Because the transaction itself has to be denominated in rupiah, the amount on the terminal will be in rupiah. What some terminals and machines then add is a separate offer: to bill your card in your home currency instead. That is a currency conversion carried out by the party operating the terminal or the machine, using their rate, before the transaction ever reaches your card issuer.

We did not find a Bank Indonesia page that sets a disclosure standard for the mark-up applied in a home-currency conversion at an Indonesian point of sale or ATM. In practice that means the screen in front of you is the only information you will get about it, which is an argument for declining the offer rather than for reading it carefully.

Choosing an ATM in Bali

ATM withdrawal limits in Bali are set by your own card issuer and by the machine's operator, and we could not verify any single national per-withdrawal cap on a Bank Indonesia page. Treat any specific figure you have read elsewhere as one bank's limit rather than the country's, and confirm your own issuer's daily and per-transaction limits before you fly. If your issuer charges a flat fee per foreign withdrawal, the limit matters more than the fee rate, because it determines how many times you pay it.

Two practical differences separate a machine in a bank's own branch lobby from a standalone machine in a shop front or a minimarket. A branch machine has staff on the other side of the wall during opening hours, which matters if the machine retains your card mid-transaction; a standalone machine leaves you with a phone number. Branch machines are also the ones you can pair with a counter visit if you need smaller denominations, since a stack of Rp100,000 notes is close to useless for a Rp15,000 parking payment.

Break large notes deliberately rather than hoping it happens. Supermarkets, chain convenience stores and hotel front desks will change a Rp100,000 note without comment; a warung at 7am often genuinely cannot. Keeping a working float of Rp5,000, Rp10,000 and Rp20,000 notes removes most of the friction of a day in Bali.

Licensed changers and unlicensed shops

Bank Indonesia licenses non-bank money changers one company at a time, under a regulation with real structural requirements, and publishes the resulting list. A KUPVA Bukan Bank — penyelenggara kegiatan usaha penukaran valuta asing bukan bank — must be a limited liability company whose shares are entirely owned by Indonesian citizens or by companies wholly owned by Indonesian citizens, must have articles of association covering the buying and selling of foreign banknotes and the purchase of travellers cheques, and must meet a minimum paid-in capital set by Bank Indonesia that may not derive from money laundering (Peraturan Bank Indonesia Nomor 18/20/PBI/2016, effective 7 October 2016, checked 16 September 2026).

The obligations that follow are the reason the distinction matters to you rather than only to the regulator. A licensed changer must hold a written policy and procedure for setting exchange rates and apply it consistently on an accountable basis, must keep records of how it calculated those rates, must disclose rates transparently, must protect customer data and handle complaints, must use dedicated bank accounts for the business, and must document underlying transactions above set thresholds and report to Bank Indonesia (English page for PBI 18/20/PBI/2016, checked 16 September 2026). A licence runs five years and is renewable. Where a business runs the activity without a licence, Bank Indonesia may recommend that the competent authorities revoke its business licence or close it down.

The table below compares the three places you can realistically change foreign banknotes in Bali and what you can check about each.

Checking a licence takes about a minute if you know where to look. Bank Indonesia's Daftar Lembaga Berizin splits into financial markets and a payment system register; the Sistem Pembayaran & Pengelolaan Uang Rupiah register is searchable by company name, category, decision number and licensing location, carries a category called Kegiatan Usaha Penukaran Valuta Asing, and shows each entry's licence or decision number alongside a status such as Berizin (Telah Operasional) or Izin Dicabut (both checked 16 September 2026). Search the company name on the shop's receipt or signage, not the trading name on the window.

If a note looks wrong

Bank Indonesia is the only institution entitled to determine whether a rupiah note is genuine, which means nobody at a counter can settle the question for you. Its Pencegahan dan Pemberantasan Uang Rupiah Palsu page sets out what to do in two situations: when a note is being handed to you, and when you find you are already holding one (checked 16 September 2026).

That last step is the one travellers skip, and it is the only one with money attached. Bank Indonesia's page states that a note confirmed counterfeit brings no compensation, whereas a note confirmed genuine does, so handing it in is strictly better than quietly spending it at a night market.

Before you leave the airport

Change or withdraw a deliberately modest first amount rather than a week's budget. A bank branch or a licensed changer at Ngurah Rai, or a bank ATM inside the terminal, is enough to cover your transfer, your first meal and a day of small payments while you find a better counter in Denpasar, Sanur or Ubud. Ask for a mix that includes Rp10,000 and Rp20,000 notes.

Three things this guide does not cover, and you should not infer them from it. It does not cover customs declaration thresholds for currency carried into or out of Indonesia, which are set by the customs authority and were not verified here. It does not cover QRIS or Indonesian e-wallet registration for foreign visitors, which has its own rules. And it does not give you any bank's ATM limit or fee, because those are issuer-specific and change without a public regulation behind them — ask your own bank in writing before you travel, and save Bank Indonesia's licence register to your phone before you need it.
