Rupiah Volatility & the Global Carry Trade: Navigating 2026 and Beyond

A staggering $2.3 trillion is currently tied up in carry trades globally, according to recent BIS data. This massive influx of capital, seeking higher yields in emerging markets like Indonesia, is increasingly sensitive to even subtle shifts in US monetary policy. The Rupiah’s recent fluctuations – a dip to Rp16,690 followed by a partial recovery to Rp16,654 on November 11th, 2025 – aren’t isolated incidents, but rather a harbinger of increased volatility as the era of easy money comes to an end.

The Fading Fed Put and Rupiah Weakness

The primary driver behind the Rupiah’s initial weakness, as reported by Antara News Jatim, is the diminishing expectation of near-term interest rate cuts from the US Federal Reserve. For months, markets have priced in a dovish Fed, fueling the carry trade. Investors borrow in low-interest-rate currencies (like the US dollar and Japanese Yen) and invest in higher-yielding assets, such as Indonesian government bonds. However, resilient US economic data is forcing a reassessment of this narrative.

This recalibration is causing a “risk-off” sentiment, prompting investors to repatriate capital to the US, strengthening the dollar and putting downward pressure on the Rupiah. The speed of this reversal is the key concern. A gradual shift would allow Bank Indonesia (BI) to manage the impact through measured interventions and policy adjustments. A sudden shock, however, could trigger a more significant Rupiah depreciation.

Carry Trade Dynamics in a Booming Global Market

Despite the headwinds, Indo Premier Sekuritas predicts the dollar carry trade will continue to thrive amidst the current global stock market boom. This seemingly contradictory outlook stems from the perception that strong equity markets provide a buffer against currency risk. Investors are willing to tolerate some Rupiah weakness if their equity investments continue to deliver robust returns.

The Indonesian Equity Story: A Double-Edged Sword

Indonesia’s strong economic fundamentals – a growing middle class, abundant natural resources, and a relatively stable political environment – are attracting foreign investment. However, this influx of capital also exacerbates the Rupiah’s vulnerability to external shocks. A correction in global equity markets could quickly reverse the flow, leading to a sharp Rupiah sell-off.

Furthermore, the reliance on foreign capital makes Indonesia susceptible to “sudden stop” scenarios, where capital flight disrupts economic activity. BI is actively working to diversify the investor base and reduce reliance on short-term speculative flows, but this is a long-term process.

Looking Ahead: Rupiah Resilience in 2026 and Beyond

The next 12-18 months will be critical for the Rupiah. The trajectory of US interest rates, the performance of global equity markets, and the effectiveness of BI’s policy responses will all play a crucial role. We anticipate increased volatility, with the Rupiah potentially testing levels of Rp17,000 against the dollar if the Fed maintains its hawkish stance and global risk appetite deteriorates.

However, Indonesia is not without its strengths. The country’s current account surplus, driven by strong commodity exports, provides a degree of insulation. Furthermore, BI has a track record of proactive intervention to stabilize the Rupiah. The key will be to strike a balance between defending the currency and supporting economic growth.

Metric	2025 (Estimate)	2026 Projection (Base Case)
USD/IDR Exchange Rate	Rp16,650	Rp16,850 – Rp17,200
Indonesia GDP Growth	5.0%	4.8% – 5.2%
US Federal Funds Rate	5.25% – 5.50%	5.00% – 5.50%
