Jakarta, Pintu News – Sanering is a monetary policy conducted by the government or central bank by drastically reducing the nominal value of a currency. The aim is to control uncontrolled inflation, reduce the money supply, and stabilize economic conditions. Unlike redenomination, which only simplifies numbers without changing purchasing power, sanering reduces the purchasing power of money circulating in the community.
Sanering is often practiced when a country’s economy is experiencing a severe crisis, such as hyperinflation or extreme fiscal imbalances. This policy is usually accompanied by the replacement of old money with new money of lower value.

Sanering occurred in Indonesia on August 25, 1959, under the administration of President Soekarno. At that time, the value of Rp500 and Rp1,000 denominations were reduced to Rp50 and Rp100, respectively. This was done to curb the post-independence and war hyperinflation. The effect was very pronounced: people’s purchasing power plummeted and trust in the rupiah currency dropped dramatically.
If sanitization is reintroduced in the future, cryptocurrencies like Bitcoin or Ethereum could be an alternative store of value. Some possible impacts:

1. What is sanering?
Sanering is a policy of drastically cutting the value of money by the government with the aim of reducing the money supply and controlling inflation. This policy is usually implemented when economic conditions are critical, such as hyperinflation.
2. What is the difference between sanering and redenomination?
Sanering reduces the purchasing power of money (its real value), while redenomination only simplifies the nominal value without changing the purchasing power. For example, redenomination turns Rp1,000 into Rp1, but goods can still be bought with the same value. Sanering, on the other hand, can make Rp1,000 worth only Rp100 in real terms.
3. When did sanering occur in Indonesia?
Sanering was carried out in 1959 when President Soekarno took office. At that time, the nominal value of denominations of Rp500 and Rp1,000 was cut to Rp50 and Rp100 respectively.
4. What is the impact of sanering on society?
Sanering can drastically reduce the value of people’s savings and assets, reduce purchasing power, and cause panic if not accompanied by strong communication and economic strategies.
5. Is sanering still possible in the modern era?
Although less likely, sanering can still occur if national economic conditions deteriorate to an extreme. However, the more commonly used policies today are devaluation, redenomination, or monetary tightening.
6. What effect does sanitization have on cryptocurrencies like Bitcoin?
Cryptocurrencies have the potential to be an alternative store of value when confidence in fiat currencies weakens due to sanitization. Cryptos could experience a surge in demand as they are perceived to be more secure and not controlled by the government.
7. Can crypto protect wealth during sanitization?
Cryptocurrencies such as Bitcoin can serve as a hedge under certain conditions, as they are not directly affected by the policy of money value cuts. However, volatility and regulation remain risk factors to be aware of.
8. What steps can the public take in the event of sanering?
Some steps that can be taken include: diversifying assets (including into real assets such as gold or crypto), maintaining liquidity, and actively monitoring the government’s economic policies.
