Rupiah Steadies Amid BI Support and Fed Outlook

Key Moments

Rupiah Supported After Leadership Shock at Bank Indonesia

USD/IDR edges higher after opening with a bearish gap but remains under pressure, trading around 18,110 during Thursday’s Asian session. The Indonesian Rupiah (IDR) is finding support as Bank Indonesia (BI) intensifies its focus on market stabilization following the unexpected departure of Governor Perry Warjiyo.

In an effort to restore confidence, BI underscored that it is leaning on a broad mix of policy tools rather than relying solely on its benchmark policy rate. The central bank pointed to a combination of direct spot foreign exchange intervention, both onshore and offshore non-deliverable forwards (NDFs), and the issuance of rupiah-denominated securities (SRBI) as key levers to manage liquidity conditions and attract foreign inflows. These measures come on top of a total of 100 basis points of rate increases implemented since May.

Fed Holds Rates but Reveals Hawkish Split

Despite the Rupiah’s support from domestic policy actions, the US Dollar (USD) may regain traction, potentially lifting USD/IDR, after the Federal Reserve (Fed) opted for a hawkish pause. At its July meeting, the Fed left the federal funds target range unchanged at 3.50%-3.75%, in line with broad market expectations. However, the decision exposed a notable hawkish divide within the Federal Open Market Committee.

Dallas Fed President Lorie Logan, Cleveland Fed President Beth Hammack, and Minneapolis Fed Chief Neel Kashkari dissented from the majority, favoring an immediate 25 basis point rate increase instead of a pause.

During the post-meeting press conference, Fed Chair Kevin Warsh emphasized that the central bank will not provide explicit forward guidance on the future rate path but remains fully determined to do whatever is necessary to return inflation to its 2% target.

Geopolitical Risks Cloud Global Market Sentiment

Broader risk sentiment continues to be restrained as geopolitical tensions in the Middle East escalate. Market appetite for risk assets has been dampened in the wake of President Donald Trump’s pledge of a decisive reaction to a recent attack on U.S. forces in Jordan.

At the same time, diplomatic efforts have reached an impasse, with talks hampered by Tehran’s firm position on retaining control over the strategically important Strait of Hormuz. The combination of rising geopolitical risk and stalled negotiations remains a headwind for global markets.

Warsh’s Message Reinforces Fed’s 2% Inflation Commitment

Fed Chair Kevin Warsh’s tone at the press conference was assessed as distinctly more forceful than usual. The FXS Speechtracker score registered at 7/10, compared with a baseline of 6/10, signaling a tougher hawkish posture.

Warsh’s insistence that “only one target and it is 2%,” along with comments that inflation “cannot be cured in 9 weeks” and that the Committee “will not hesitate to act,” highlighted a firm commitment to price stability, even as he acknowledged strong economic resilience and significantly higher nominal and real yields. By emphasizing that the Committee is avoiding explicit forecasting and instead concentrating on trends and underlying inflation dynamics amid various shocks, Warsh underscored an approach that is data-aware but not strictly data-bound, keeping expectations anchored on the 2% objective.

FXS Fed Sentiment Index Signals Strong Hawkish Bias

The FXS Fed Sentiment Index rose by +18.94 points to 147.58, a level characterized as clearly hawkish and consistent with the stronger tone captured by the FXS Speechtracker. This substantial increase reflects market perceptions that the Fed remains firmly committed to achieving its 2% inflation goal.

This backdrop is viewed as supportive for the US Dollar relative to its peers, reinforcing the prospect that a resolute Fed stance could keep Dollar bulls engaged even as emerging market currencies like the Rupiah benefit from local policy support.
