Rupiah to dollar rate near record low as Fed hike bets grow

What happened. On Wednesday, November 11, the rupiah lost ground against the US dollar. According to Refinitiv data cited by CNBC Indonesia, it opened at Rp18,095 per dollar, 0.28% weaker, after two straight days of gains. On Tuesday it closed at Rp18,045, up 0.14% from Rp18,070. Bank Indonesia's JISDOR reference rate was Rp18,154 for November 11 and Rp18,059 for November 10. Stockbit says the rupiah closed at 18,145, down 0.5%. The figures differ a little because they come from different sources and times.

Why it is happening. The push came from the US. The consumer price index rose 0.4% month on month in October, against a 0.3% forecast. Core inflation was 0.3% against 0.2% expected, Stockbit adds. Before the data came out, Fed Governor Christopher Waller said the Fed needs to raise rates in December. Stockbit says he also allowed for a 0.5 percentage point hike if core inflation stays at 0.3%.

What markets show. According to CNBC Indonesia, the odds of a December hike on CME FedWatch are near 91%. Stockbit gives 85% at Tuesday's close, up from 76% on November 6. The two-year US Treasury yield, which reacts fast to rate expectations, jumped about 18.44 basis points to 4.731%. A basis point is one hundredth of a percentage point. The US dollar index (DXY), which compares the dollar with six major currencies, stood at 102.294 at 9 a.m. Jakarta time, after a 0.57% rise a day earlier.

What it means for the rupiah. A weaker rupiah means each dollar costs more rupiah. CNBC Indonesia says higher US yields make dollar assets more attractive and can limit flows into emerging economies, which adds pressure on the rupiah. Stockbit says a more hawkish Fed may call for a stronger response from Bank Indonesia. The Bloomberg consensus for now is that the central bank raises its rate by 0.25 percentage points to 6% by March 2027.

What we do not know. Stockbit calls 18,189 the record low of the rupiah but gives no date. The pages we opened do not give one either, and we did not check that level against another source. We also do not know what the Fed will decide in December.
