Indonesia’s Base Money Grows 16.3%: Can Liquidity Support Bitcoin?

Indonesia’s adjusted base money, or M0 Adjusted, reached Rp2,281.5 trillion in August 2026. According to Bank Indonesia, the amount increased by 16.3% from August of the previous year.

Growth remained high, but the pace eased from 17.1% year on year in July. The difference of 0.8 percentage points indicates that base money was still expanding rapidly, although its momentum was no longer as strong as in the previous month.

It is tempting to turn the data into a simple conclusion that more money will automatically lift Bitcoin. The relationship is more complicated. M0 measures the base layer of the monetary system, not the amount of investment capital waiting to purchase crypto.

Before liquidity can influence Bitcoin demand, money needs to pass through several stages. Banking liquidity must be transmitted into credit or transactions, funds need to reach households and businesses, and owners of those funds must have the capacity and willingness to invest in Bitcoin rather than other alternatives.

Bitcoin also trades globally. Changes in Indonesia’s M0 represent only a small part of the liquidity that shapes BTC prices. Federal Reserve policy, US bond yields, dollar strength, spot flows, stablecoin liquidity, and leverage may have a much larger influence.

The Main Figures from Bank Indonesia

Bank Indonesia reported several figures in its August 2026 M0 Adjusted release:

• M0 Adjusted reached Rp2,281.5 trillion.

• M0 Adjusted grew 16.3% year on year.

• Growth eased from 17.1% year on year in July 2026.

• Adjusted commercial-bank deposits at Bank Indonesia grew 19.0% year on year.

• Currency in circulation increased by 12.9% year on year.

The difference between 17.1% and 16.3% is 0.8 percentage points. This represents a slowdown in the growth rate, not a decline in the amount of base money.

M0 Adjusted was still higher than a year earlier. Describing the data as a liquidity contraction or tightening would therefore be inaccurate based solely on the annual growth figures.

What Is M0 Adjusted?

M0 represents forms of money that are closest to the central bank. It broadly reflects currency in circulation and specified commercial-bank deposits held at the central bank.

It is called base money because it forms part of the foundation for money creation and liquidity distribution within the financial system. Base money, however, is not the same as the total amount households can immediately use to purchase goods, equities, gold, or Bitcoin.

Where the money is located and how each component functions determine whether that liquidity can influence economic activity.

Currency in Circulation

Currency in circulation covers physical money issued to support transactions by households and businesses.

An increase can reflect stronger consumption, seasonal cash needs, activity in the informal economy, or changes in payment habits. It does not necessarily mean households have more money available to invest.

If real incomes are under pressure or living costs are rising, additional cash may be absorbed by daily expenses. Under those conditions, growth in currency circulation does not automatically create demand for risk assets.

Commercial-Bank Deposits at Bank Indonesia

Commercial-bank deposits at Bank Indonesia are funds within the banking system, not household investment balances.

These deposits can support interbank settlement, regulatory requirements, and liquidity management. An increase may give banks more room to conduct financial activity, but it does not guarantee that they will expand lending.

Banks still examine borrower quality, capital requirements, default risk, and credit demand. When businesses and households are reluctant to borrow, liquidity can remain inside the banking system without producing a substantial increase in spending or investment.

Why Does Bank Indonesia Use an Adjusted Measure?

Bank Indonesia explains that M0 Adjusted isolates the decline in commercial-bank deposits at the central bank caused by liquidity incentives.

The central bank began applying this adjustment in January 2025 to provide a clearer view of base-money developments and the effect of its liquidity policy.

Without the adjustment, changes in bank deposits caused by policy design could make M0 appear weaker or stronger than its underlying condition. The adjusted measure attempts to reduce that distortion.

Readers should therefore avoid comparing M0 Adjusted with another series without checking whether the definitions and methodologies are consistent. A methodological change can create a statistical difference that does not reflect a change in economic behaviour.

Growth Is High, but Momentum Has Slowed

Annual growth of 16.3% means the level of M0 Adjusted remained substantially higher than in August 2025. It does not mean base money increased by 16.3% during August 2026 alone.

A year-on-year figure compares one month with the corresponding month of the previous year. It is therefore influenced by conditions at both points in time.

Annual growth can slow even if the amount of base money continues to rise from the previous month. Annual growth can also accelerate because the comparison base was low, without a large inflow occurring during the latest month.

Several concepts should be kept separate:

• The M0 level shows the amount of base money at a specific time.

• Annual growth shows the change from the same month of the previous year.

• Monthly growth shows the change from the previous month.

• Acceleration means the growth rate is becoming faster.

• Deceleration means the growth rate is slowing, even if the amount is still increasing.

The August release provides a level and an annual growth rate, but it does not explain where liquidity moves after entering the system. Other indicators are required before drawing a connection with Bitcoin.

M0 Is Not the Entire Money Supply

M0 describes only the base layer of the monetary system. It does not include every deposit and instrument available to households and businesses for transactions.

Broad money, or M2, has wider coverage. M2 generally includes currency, transaction deposits, and other deposits within the financial system according to Bank Indonesia’s statistical definitions.

The distinction matters because higher bank reserves do not necessarily translate into more deposits and credit in the private sector. If transmission is working, M0 growth may be followed by higher M2 and lending. If transmission is weak, additional base money can remain inside the banking system.

The relationship can be summarised as follows:

M0 provides the liquidity foundation, while M2 and credit help show whether that liquidity has spread into the wider economy.

M0 growth without comparable changes in M2 or credit therefore sends a different signal from a situation in which all three increase together.

The Liquidity Route from M0 to Bitcoin

There is no direct channel connecting higher commercial-bank deposits at Bank Indonesia with Bitcoin purchases. Liquidity transmission takes place through several stages, and each stage can strengthen or break the relationship.

A. Banking Liquidity Must Become Credit or Transactions

Greater liquidity can give banks more room to extend financing. Banks do not automatically issue loans simply because funds are available.

Lending still depends on borrower quality, collateral, funding costs, capital requirements, and the economic outlook. Households and businesses must also be willing to borrow.

If banks remain cautious and borrowers do not want additional debt, M0 growth can stop at the banking-system level.

B. Credit Must Create Income or Investment Capacity

Credit that reaches the private sector does not necessarily enter financial assets. Funds may be used to purchase homes, finance working capital, build inventory, or cover operating expenses.

To affect Bitcoin, part of the funding or its economic impact needs to increase income, savings, or the capacity to take risk.

If additional liquidity is used mainly to maintain consumption or repay obligations, its effect on crypto demand will be limited.

C. Fund Owners Must Choose Risk Assets

Once funds reach the private sector, their owners still need to decide how to allocate them. The alternatives include deposits, bonds, equities, gold, property, business spending, and crypto assets.

The choice depends on expected return, interest rates, inflation, income stability, and risk tolerance.

When deposit rates or yields on rupiah securities remain high, investors can earn returns from instruments with relatively lower volatility. The opportunity cost of holding Bitcoin then increases.

D. Rupiah Funds Must Enter Crypto Infrastructure

Indonesian investors generally begin with rupiah before acquiring digital assets. The process requires a compliant account, payment access, transaction liquidity, and a decision to allocate funds.

M0 growth does not automatically increase rupiah deposits into crypto services. Confirmation needs to come from relevant data such as spot volume, active users, transaction frequency, or observable inflows.

E. The Exchange Rate Changes Rupiah Returns

Bitcoin’s global price is generally quoted in dollars or dollar-referenced stablecoins. Indonesian users then see that value converted into rupiah.

The relationship can be simplified as:

BTC/IDR ≈ BTC/USD × USD/IDR

Bitcoin can remain flat in dollars but rise in rupiah when the local currency weakens. It can also rise in dollars while producing a smaller rupiah gain when the rupiah appreciates.

A change in BTC/IDR caused by the exchange rate does not prove that domestic liquidity moved the global Bitcoin price.

F. Global Liquidity Remains More Influential

Bitcoin trades in a global market that operates around the clock. Demand is influenced by dollar liquidity, Federal Reserve policy, US bond yields, investment-product flows, institutional activity, stablecoins, and leverage.

Changes in Indonesia’s M0 may influence the ability of some domestic users to purchase assets, but their effect on the global price is likely smaller than international capital flows.

Bitcoin analysis should therefore not rely on one country’s M0 as its only variable.

Liquidity Is Not the Same as Risk Appetite

Liquidity describes the availability of money and access to funding. Risk appetite describes the willingness to use that money to accept uncertainty.

The two can move in different directions.

Banks may have substantial liquidity while credit demand remains weak. Households may hold more cash because they are concerned about their income. Companies may retain funds to pay debt or protect their operations.

Under those conditions, M0 can grow without producing strong Bitcoin demand.

Bitcoin can also rise while Indonesia’s M0 growth slows if stronger global catalysts are present. Lower dollar yields, institutional spot flows, regulatory changes, or higher stablecoin liquidity can support demand.

A short-term correlation does not establish causation. M0 and Bitcoin may move in the same direction because both are responding to a third factor, such as changes in global monetary policy or risk sentiment.

A visual comparison of two charts is not sufficient. Causal analysis requires consistent data, an adequate time period, a reasonable transmission lag, and controls for other variables.

Does M0 Growth Always Cause Inflation?

Base-money growth can add to inflationary pressure if liquidity is transmitted into credit and demand for goods and services grows faster than productive capacity.

The effect is not automatic. Liquidity may remain inside the banking system, replace another source of financing, or be absorbed by greater demand for cash.

The velocity of money also matters. The money supply can increase while the effect on prices remains limited if households and companies choose to save or retain cash.

Inflation does not produce a uniform response from Bitcoin either. A scarce-asset narrative may support demand under some conditions, while high inflation can lead to higher interest rates and lower appetite for risk assets.

The relationship is therefore not as simple as more money, higher inflation, and a higher Bitcoin price. Each stage requires separate evidence.

Additional Data Still Required

M0 is a starting point, not a complete picture of the liquidity available to the private sector. Several other indicators are needed to determine whether monetary transmission is taking place.

Monetary and Economic Indicators

• Broad-money growth, or M2.

• Overall bank-credit growth.

• Consumer and working-capital lending.

• Deposit and lending rates.

• Yields on rupiah securities.

• Inflation and real-income growth.

• Retail sales and consumption activity.

• JISDOR and USD/IDR volatility.

Bitcoin Indicators

• BTC/USD and BTC/IDR prices.

• Spot-trading volume.

• Derivatives open interest.

• Funding rates.

• Long and short liquidations.

• Changes in stablecoin liquidity.

• Flows into Bitcoin investment products.

• Wallet activity and on-chain transfers.

If M0 and M2 grow, lending strengthens, funding costs decline, and Bitcoin spot volume increases, the liquidity thesis receives stronger support.

If M0 rises while credit remains weak, interest rates stay high, and funds remain in defensive instruments, the effect on Bitcoin will be more limited.

Three Ways to Interpret the Data

M0 Adjusted growth can have different implications depending on its transmission. The following scenarios separate those possibilities without turning them into price predictions.

A. Liquidity Spreads into the Economy and Investment Assets

Banks extend more credit, business activity expands, and household incomes improve. Real interest rates are not excessively restrictive, allowing some investors to increase exposure to risk assets.

Under these conditions, part of the liquidity may reach equities, gold, and crypto. Support for Bitcoin would be more convincing if price gains were accompanied by spot volume, active-user growth, and observable fund flows.

M0 would serve as an early indicator in this scenario, not final proof.

B. Liquidity Remains Inside the Banking System

Commercial-bank deposits at Bank Indonesia increase, but lending and financing demand remain weak. Households and companies stay cautious, while investors keep funds in deposits or fixed-income securities.

In this scenario, M0 can grow without providing meaningful support for Bitcoin. Liquidity is available, but risk appetite and transmission into the private sector are insufficient.

The main signal would be M0 growth without a corresponding acceleration in M2, credit, consumption, or risk-asset spot volume.

C. Domestic Liquidity Grows While Global Conditions Pressure Bitcoin

Indonesia’s liquidity improves, but the Federal Reserve remains restrictive, US yields rise, or the dollar strengthens. Those global factors may pressure Bitcoin in dollar terms.

If the rupiah also weakens, a BTC/USD decline may appear smaller in BTC/IDR. Bitcoin could even rise in rupiah while remaining broadly flat in dollars.

Users looking only at a rupiah chart may incorrectly treat the movement as evidence of surging domestic demand.

The Role of Interest Rates in Liquidity Transmission

Interest rates determine borrowing costs and the alternative returns available to investors. High liquidity may not support Bitcoin when credit remains expensive and rupiah instruments offer attractive yields.

When interest rates fall, financing costs may decline and returns from defensive instruments may become less attractive. This can increase interest in assets offering higher potential returns, including Bitcoin.

The reason for a rate cut still matters. If rates fall because the economy is weakening sharply, investors may continue to prefer cash and defensive assets.

Interest rates influence Bitcoin through several channels. Their effect can pass through credit, asset valuations, USD/IDR, capital flows, and risk sentiment.

How to Read Bitcoin After the M0 Release

One month of M0 data should not be used as a standalone trading signal. Users may compare the release period with Bitcoin’s movement, but the analysis method needs to remain consistent.

First, use matching observation dates. Do not compare a monetary figure for the end of August with a selectively chosen Bitcoin period simply because the result supports the preferred conclusion.

Second, separate closing prices from intraday movements. A brief price spike that later reverses does not have the same meaning as a change sustained into the daily or weekly close.

Third, examine volume. A price increase supported by spot buying has a different structure from a move driven primarily by short liquidations.

Fourth, review leverage. Rapid increases in open interest and funding rates may indicate that momentum is becoming increasingly dependent on derivatives positions.

Fifth, allow for transmission lags. Liquidity changes do not have to affect assets on the data-release date. Lending, fund allocation, and portfolio rebalancing may take time.

The lag should be chosen according to the economic mechanism, not after observing the price result. Changing the analysis period to fit the outcome can introduce bias.

Confirmation and Invalidation Indicators

The liquidity thesis needs supporting evidence. M0 growth becomes more relevant to Bitcoin when monetary transmission and asset demand move in the same direction.

Indicators Supporting the Liquidity Thesis

• M2 grows alongside M0.

• Bank-credit growth strengthens.

• Real interest rates or funding costs decline.

• Income and consumption improve without a sharp increase in inflation.

• Bitcoin spot volume rises.

• Price gains are not dominated by short liquidations.

• Funding rates remain controlled.

• Open interest grows in proportion to spot volume.

• The rupiah remains relatively stable.

• Global stablecoin liquidity increases.

Indicators Weakening the Liquidity Thesis

• M0 grows while M2 and credit weaken.

• Banking liquidity does not reach the private sector.

• Interest rates and defensive-asset yields remain high.

• Inflation reduces household real income.

• The dollar strengthens and global liquidity tightens.

• Bitcoin rises on weak spot volume.

• Open interest and funding rates increase too quickly.

• BTC gains are driven primarily by a short squeeze.

• Stablecoin and investment-product flows weaken.

• The rupiah falls sharply, making the BTC/IDR increase mainly an exchange-rate effect.

One indicator is not enough to determine Bitcoin’s direction. A combination of signals can, however, help distinguish liquidity that is reaching assets from liquidity that remains within the monetary system.

Conclusion

M0 Adjusted growth of 16.3% shows that Indonesia’s base money continued to expand rapidly. It reached Rp2,281.5 trillion in August 2026, although the growth rate slowed by 0.8 percentage points from July.

The data provide context for domestic liquidity conditions, but they do not prove that new funds are flowing into Bitcoin. Part of M0 consists of commercial-bank deposits at Bank Indonesia, while higher currency circulation may reflect transaction and consumption needs.

For liquidity to support Bitcoin, transmission needs to appear in M2, credit, income, savings, and asset allocation. Domestic conditions must then be assessed alongside interest rates, USD/IDR, Federal Reserve policy, dollar liquidity, stablecoin flows, and the structure of the Bitcoin market.

The most defensible conclusion is that liquidity can provide supportive conditions, but M0 alone is insufficient evidence that Bitcoin is receiving that support. The thesis becomes stronger when money growth coincides with improving credit, lower opportunity costs, genuine spot inflows, and greater risk appetite.

The next signal is not only September’s M0 figure. Developments in M2, credit, interest rates, the rupiah, spot volume, and leverage will show whether liquidity is actually moving from the monetary system into risk assets.
