Rupiah Weakens and Government Bond Yields Rise: What Impact Will This Have on Crypto?

The weakening of the rupiah and the increase in government bond yields do not automatically cause crypto to rise or fall. 

For Indonesian investors, the two work through different channels: the exchange rate affects the value ofcrypto in rupiah, while rising bond yields may reflect changes in investment attractiveness and risk perception.

To understand the impact of SBN yields on crypto, readers need to distinguish domestic market pressures from global Bitcoin movements.

Bitcoin Price in rupiah could increase because the dollar strengthens, even though the price in dollars does not change.

Key Takeaways

• The SBN yield of 7.62% and the auction result of 7.54% differ in the date and measurement context.

• A weakening Rupiah may raise the value of Bitcoin in Rupiah terms, but it does not guarantee a profit.

• Rising yields don't necessarily indicate that funds are moving into crypto; global sentiment and liquidity remain key.

SBN Yield 7.62 Percent: What's the Context?

On October 29, 2026, the 10-year SBN yield reached 7.62% as of October 28. 

For comparison, the US government bond yield is reported at 5.01%, resulting in a difference of 261 basis points. One basis point is equal to 0.01 percentage points.

The rupiah is also hovering around Rp18,183 per US dollar, having weakened by around 8.2% since the start of the year.

This figure is a snapshot in the news, not a real-time rate.

Meanwhile, IDNFinancials record the weighted average yield won for FR0111 amounted to 7.54% at the October 27 auction. 

Incoming bids reached Rp31.09 trillion, down 52.1% from the previous auction.

The figure of 7.54% should not be treated as an identical measure to the yield of 7.62% a day later.

Why Doesn't a High Yield Necessarily Attract Investors?

Yield describes the return based on the price and payment flow of a bond.

In fixed-rate bonds, prices and yields move inversely: when prices fall, yields rise.

An increase in market yield does not automatically change the coupons on bonds already issued.

Foreign investors also take exchange rate changes into account.

Profits from rupiah bonds may be reduced when investment returns are converted back into dollars.

Therefore, a high yield spread may not be sufficient to offset the risk of exchange rate fluctuations and falling bond prices.

Bloomberg Technoz quotes economist Josua Pardede as saying that the increase in yields could reflect additional risk compensation.

The report also noted net foreign purchases of SBN throughout October to October 28, despite a combined net portfolio outflow.

So, the pressure on the rupiah does not prove that all foreign investors are selling SBN.

The Impact of SBN Yields on Crypto Is Not Direct

Rising bond yields could increase the attractiveness of interest-bearing instruments compared to holding Bitcoin, which doesn't pay coupons.

However, the impact depends on the cause of the yield increase, the risk of the instrument, and the investor's goals.

There is no basis to conclude that the increase in Indonesian government bond yields can determine the global price of Bitcoin.

An S&P Global study using data through March 2023 shows that the relationship between crypto and monetary conditions is not simple.

Market confidence, adoption, technology, and liquidity also play a role.

The study did not test the specific relationship between Indonesian SBN yields and Bitcoin.

An increase in yield does not automatically increase all mortgage or business credit interest rates.

Transmission to banking interest rates may be slow and incomplete, as discussed in Bank Indonesia publications.

Bitcoin When the Rupiah Weakens: Separating Dollar and Rupiah Prices

In terms of approximation, the price of Bitcoin in rupiah can be calculated asBTC price in dollars × rupiah exchange rate per dollar. 

Actual transaction prices may differ due to liquidity, differencesbuy-sell prices, and platform fees.

The following calculations are simulations, not market data or predictions. All scenarios are based on a BTC value of US$80,000 and an exchange rate of Rp18,000 per dollar, resulting in an initial value of Rp1.44 billion.

For investors who already own Bitcoin, a weakening rupiah could increase the value of their holdings in rupiah if the price of Bitcoin in dollars remains stable.

However, Bitcoin is not a store of dollars: a drop in the price of BTC could wipe out the benefits of such exchange rate changes, even causing losses.

What Should Indonesian Investors Pay Attention to?

Compare BTC movements in dollars and rupiah at the same time.

Then, examine whether the yield increase is accompanied by changes in the global dollar, capital flows, or monetary policy expectations. Avoid taking any single indicator as a buy or sell signal.

Also pay attention to the asset risk.

Bitcoin remains volatile, while stablecoins carry issuer risk and failure to maintain a price peg.

S&P Global also cautioned that crypto's track record is not yet sufficient to confirm its ability to act as a hedge against inflation.

FAQ

Does crypto rise when the rupiah weakens?

Not always. Rupiah prices are affected by exchange rates and changes in global crypto prices.

Is the 7.62% SBN yield the same as the coupon?

No. Yield takes into account the bond price and its payment stream, while coupons follow the terms of issue.

Why do the auction results show 7.54%?

This figure represents the weighted average yield of FR0111 at the October 27 auction, as opposed to the October 28 yield observation.

Does the increase in yields prove that funds are flowing into Bitcoin?

No. That conclusion requires evidence of investment flows, not just yield movements.

Does Bitcoin guarantee protection against rupiah depreciation?

No. A global decline in Bitcoin prices could outweigh the benefits of a rise in the dollar's conversion rate.
