Demonetisation Lessons from Brazil

Public policies are best when a lot of reason goes into their formulation and passion into their implementation.Those looking for an effective recipe for formulation could learn a lot from Brazil. It has demonetised its currency 8 times since 1942 and thrice simply knocked off the last 3 digits of its currency overnight i.e. like a 10,000 Cruzeiro (then Brazilian currency) will be 10 Cruzeiro from next day morning.

Lessons from 1830s to 1942.

Even before from 1830s it has been compelled to experiment with its currency due to evolving politics. The early experiments are to do with metallic convertible bases like silver and gold, metallic copper coins, birth of parallel paper money,  etc.

In early 1830s in order to stabilise the external value of Mil-Reis (then currency), the centre starved supply of currencies reducing the circulation of copper coins in the provinces. The provinces responded by issuing their own notes to neutralise demonetisation. Promissory Notes issued by Commercial banks valid for 15 days by law began to be accepted far beyond their due dates. (Source: Page 39-43,  Monetary Statecraft in Brazil: 1808–2014, Kurt Mettenheim)

Some other time commercial banks were allowed to issue bank notes (like in Hong Kong where currencies were issued by Standard Chartered and HSBC till accession). This led to loss of control of central authority and dilution of monetary policies.

Brazil through its history has clearly proved that no one can ‘starve’ the people of currency for far too long.


This period was mostly about high government expenditure, unbridled fiscal gaps and high inflation. Brazil demonetised 8 times before the last one in 1994.

It has had to change its currency, the ultimate form of demonetization for every conceivable reason – to tackle black money (Indian objective), to tackle hyper inflation, tackle daily cumulating interest rates of 3% (which is nearly 50,000% p.a.), base erosion, commodity price volatilities especially in Copper or just to avoid confusion (if Brazil had retained its currency same as in 1942, it would be 1 US $ =  2750 followed by 18 zeros, a nightmare for the accountants). They have been far deeper than t he Indian type demonetisation – the entire spectrum was replaced and the currency itself renamed.

The last in 1994.

The most recent in 1994 seemed Quixotic. It was aimed more at breaking the psychology of inflation. With 100% inflation consistently for 14 preceding  years (in 4 years over 1000%), shops had to revise prices 3 times everyday. That is when the government decided to use two currencies simultaneously – one virtual for counting the real value of currency and another for payments and settlement – and every shop having to display its prices in both and revise it 3 times a day.

But unexpectedly, people started anchoring their values against the real value (which was set near 1 Real Value unit = 1 US$).  Within a quarter or so, it was clear people were not rushing any longer to shops to avoid their currency buying less than when they started from home. Inflation abated and the real value became the Real the official unit. It was perhaps one of its most successful experiments that has lasted till date.

Lessons from Brazil

People will seek ways to settle transactions in the most cost and effort efficient ways. For many transactions in much of India, using currencies across the counter is still the most efficient option. In 1970s and 80s, when there was a coin shortage of sorts,  Chintamani co-operative superstore in Coimbatore used to issue their own tokens. These slowly gained acceptance with public so much so that even government owned busses and offices used them.

The parallel systems will start issuing notes and IOUs which will be strictly ‘enforced’ amongst its members through extra legal authorities.

One thing Brazil has always got right (between 1942-1994) is to have the 1,2,5,10,20,50,100 note sequence – considered the most friendly from transaction settlement point of view.

Currencies are as much about psychology and convenience as values for accounting and transaction, as the 1994 experiment so decisively proved.

The best way to demonetise is not to have one – avoid inflation, avoid unjustifiable or un-implementable tax systems, and not to issue too much of it anyway. Brazil has about 3% as currency/GDP whereas India’s is11-12%. Government should have incentivised and reduced it by 1% every year rather than force it in one lump.

A parade of demonetisations has not exactly curbed either parallel economy or corruption in Brazil. Corruption and black money is so rampant, their President was recently impeached for corruption, their biggest real estate tycoon is behind bars and may have to spend the rest of life there if not politically rescued.

Why black money or parallel economy, there is a near parallel administration being run by the mafia through drugs, extortion, violent thefts (one murder every 10 minutes i.e 140 a day, down of course from 600 a day not so long ago), etc. none of which will be happening through tax paid cheque money transfers.


In summary Brazil offers 3 ground rules (perhaps not with successful examples as much as negative narratives):

  • the way to tame inflation is not periodic demonetisations but curb state populism,
  • the way to curb black money and illegal economy is not starving people of cash but well thought out tax policies and effective punishments, and
  • the way to protect free trade from causing domestic unemployment problems is to maintain the external value of the currency which in turn is achieved by restricting external capital inflows to just what is required for financing current account deficits. (Donald V Coes, Macro Economic Policies and Growth in Brazil, 1964-90)

One would definitely give credit to both the government and RBI for curbing state populism within FRBMs. But given the levels of corruption in tax collection systems itself, black money curbing through demonetisation seems an ill fitting solution. Unemployment is rampant and growing due perhaps to highly overvalued Rupee and extra terrestrial real interest rates.

The daily dose of RBI circulars does indicate that someone is extremely alert at the wheel but whether he knows the destination and if it will deliver enough gains for the pains people are experiencing, time alone will tell.
