Singapore Tightens, Indonesia Faces a Test

The Big Picture
Singapore delivered the day’s only monetary-policy tightening, using the exchange rate rather than an interest rate to get ahead of the next inflation impulse.

The Monetary Authority of Singapore unexpectedly increased, “very slightly”, the rate at which its Singapore dollar nominal effective exchange-rate policy band appreciates. The adjustment was smaller than April’s tightening, while the width and centre of the band were unchanged. MAS acted despite core inflation of only 1.6% in June because it expects underlying inflation to increase from July and remain elevated until around the middle of 2027.

Indonesia, by contrast, received an institutional shock. Bank Indonesia Governor Perry Warjiyo resigned before completing his second term, citing personal reasons. Senior Deputy Governor Destry Damayanti was appointed interim governor and promised policy continuity, but the rupiah weakened to 18,000 per dollar as investors questioned whether the next appointment would preserve the central bank’s operational independence.

The two developments illustrate different ways in which the exchange rate enters monetary policy. Singapore strengthened its currency deliberately to restrain imported inflation. Indonesia’s currency weakened because a change in leadership created uncertainty about the future reaction function.

Meanwhile, Brent crude surrendered much of last week’s surge above $100, falling to around $89–90 after the US paused attacks on Iran and Tehran indicated that it would reciprocate. The decline reduced the immediate inflation alarm ahead of the Federal Reserve, Bank of England and Bank of Japan meetings, but did not remove it. Markets continued to assign roughly a one-in-three probability to a Fed increase this week.

Singapore: Tightening Through the Currency
MAS very slightly increased the slope of the Singapore dollar nominal effective exchange-rate band, thereby allowing the currency to appreciate more rapidly against the currencies of the country’s principal trading partners. Twelve of the 16 analysts surveyed by Reuters had expected no change, while four had forecast tightening.

Unlike most central banks, MAS does not primarily conduct monetary policy through a short-term interest rate. It manages the slope, centre and width of an undisclosed trade-weighted currency band. A steeper slope represents tighter policy because a stronger Singapore dollar lowers the domestic price of imported goods and services.

The latest move was deliberately incremental. MAS left the centre and width of the band unchanged and made a smaller adjustment than in April. This suggests that the authority is not responding as though Singapore faces an immediate inflation emergency. It is attempting to reduce the probability that today’s energy shock becomes tomorrow’s broader inflation problem.

The domestic circumstances permit such pre-emption. Singapore’s economy expanded by a stronger-than-expected 5.7% year on year in the second quarter, supported by AI-related demand. At the same time, electricity tariffs increased 17% in July because of higher imported natural-gas prices. MAS warned that another disruption to Middle East energy supplies could produce a sharper increase in inflation, while strong investment could create additional demand spillovers.

Jakarta: Credibility Becomes a Currency Risk
Warjiyo’s resignation came after eight years as governor and well before the end of his second five-year term. The government said he stepped down for personal reasons, without providing further detail. Destry, a career economist and senior deputy governor, was appointed interim governor before markets opened.

Her immediate commitment was continuity. Destry said Bank Indonesia would continue to prioritise stability in the rupiah and financial system. Yet the currency closed 0.36% weaker at 18,000 per dollar, near the record low of 18,190 reached in June. The rupiah has depreciated by more than 7% during 2026 despite 100 basis points of rate increases since May.

Warjiyo’s departure arrives when Bank Indonesia’s institutional position is already under examination. Parliament passed legislation in June strengthening the central bank’s responsibility to support economic growth and allowing lawmakers to make binding recommendations to financial regulators and the central bank. President Prabowo Subianto has set an ambition of achieving 8% growth by 2029, increasing investor sensitivity to any suggestion that monetary policy could be subordinated to that objective.

The appointment process now becomes central. The president can submit as many as three candidates to parliament, which will conduct a fit-and-proper test and select the governor. No candidates had been formally proposed by Monday afternoon. Moody’s and Fitch have already placed negative outlooks on Indonesia’s sovereign rating, partly because of concerns over changes to the central bank’s mandate, while S&P has retained a stable outlook.

Washington: Oil Falls, but the Decision Remains Live
The retreat in oil prices has changed the immediate context for the Federal Reserve’s July 28–29 meeting.

Brent fell sharply on Monday after the US temporarily suspended its attacks on Iran and Tehran indicated that it would refrain from retaliatory attacks while the pause continued. The decline brought crude back below $90 during European trading after it had exceeded $100 last week. US Treasury yields also eased as markets reduced some of the inflation premium accumulated during the previous week.

Futures markets assign approximately a 32% probability to a 25-basis-point increase, compared with about 10% two weeks ago.

The probability is a measure of uncertainty rather than a consensus forecast. A temporary energy-price increase cannot by itself demonstrate that inflation will become persistent, particularly when June’s core CPI report was softer than anticipated. But the Fed also faces inflation that remains above its target, resilient demand and uncertainty about how tariffs and energy costs will affect prices during the third quarter.

Frankfurt: Surveys Argue for Patience, Kazimir for Pre-emption
The ECB’s post-meeting surveys provided evidence that inflation expectations remain contained despite the energy shock.

Median household expectations for inflation over the next 12 months fell to 3.0% in June from 3.5% in May. Three-year expectations declined to 2.8% from 2.9%, while five-year expectations remained unchanged at 2.4%. Perceived inflation also decreased, although uncertainty remained above the level prevailing before the Middle East conflict began.

Professional forecasters expect euro-area inflation to average 2.7% in 2026, 2.2% in 2027 and 2.0% in 2028. Their growth projections were weaker, at 0.6% for 2026, 1.2% for 2027 and 1.3% for 2028. The surveys therefore describe an economy facing a near-term price shock but not yet an unanchoring of medium-term expectations.

Slovak central-bank Governor Peter Kazimir nevertheless argued on Monday that at least one additional ECB increase would probably be required. He said only very convincing economic and geopolitical evidence would prevent him from supporting a September move, warning that second-round effects can become difficult to reverse by the time they are fully visible. Markets currently price the first increase by October and a second by March.

Moscow: A Cut Accompanied by a Higher Rate Path
The Bank of Russia unexpectedly reduced its key rate by 25 basis points to 14% on Friday, even as it raised its inflation forecast and lowered its growth projection.

The central bank now expects inflation of 6–7% in 2026, compared with its previous forecast of 4.5%–5.5%. It reduced its GDP growth range to 0%–1% from 0.5%–1.5%. Fuel shortages and disruptions to production contributed to higher prices, while household inflation expectations increased sharply during July.

Governor Elvira Nabiullina characterised the acceleration as temporary and continued to estimate underlying inflation at 4%–5%. The Bank expects weaker demand to limit the ability of businesses to transfer costs into selling prices. However, it simultaneously increased its projected key-rate path for 2026 and 2027 because of fiscal expansion and the risk of second-round effects.

Mint Street: Rate Patience
Governor Sanjay Malhotra reinforced the case for an August pause in an interview with The Hindu BusinessLine published Monday. He said the current 5.25% repo rate was appropriate for the prevailing growth-inflation dynamics and described generalised inflation pressures as modest so far, while acknowledging a real risk that higher food and fuel prices could develop into broader inflation. The formulation suggests that the MPC will not respond mechanically to headline inflation moving above 4%, but will look for evidence that the supply shock is spreading into underlying prices, expectations and wage or price-setting behaviour

Islamabad: April’s Hike Is Left to Work
The State Bank of Pakistan kept its policy rate unchanged at 11.5%, extending the hold that followed its 100-basis-point increase in April.

Governor Jameel Ahmad said inflation could moderate during July and decline over the following two months, provided the US-Iran conflict does not escalate again. Pakistan’s dependence on imported energy makes both the oil price and the exchange rate important parts of the inflation outlook.

Policy Themes
Exchange rates are becoming active monetary instruments. Singapore used appreciation as its principal tightening mechanism. The RBI used spot intervention and swaps to stabilise the rupee. Indonesia demonstrated the reverse channel, where institutional uncertainty itself can weaken the currency and tighten market conditions.

Small moves can carry large signals. MAS made a deliberately modest adjustment, but showed that it will act before inflation broadens. Russia delivered only a 25-basis-point cut, while raising its projected future rate path. In both cases, the message about future policy was more consequential than the immediate magnitude.

Central banks are separating shocks from propagation. The Fed, ECB, RBI, Bank of Russia and SBP are all attempting to distinguish an increase in energy prices from a sustained process involving expectations, wages and underlying inflation. Their differences lie in how much evidence they require before acting.

Policy Calendar | July 28–August 5

The Signal
Monday produced both a monetary-policy action and an institutional-policy shock.

Singapore tightened before higher energy costs became broadly embedded in inflation. By moving the exchange-rate slope only very slightly, MAS demonstrated that pre-emption need not involve a large or disruptive change.

Indonesia showed why central-bank governance belongs inside the monetary reaction function. Warjiyo’s resignation does not itself determine future policy, but the successor’s credibility will affect the rupiah, foreign demand for Indonesian assets and the level of interest rates required to maintain stability.

The oil-price decline has provided relief elsewhere, particularly for the Fed, Bank of England, Bank of Japan and RBI. It has not resolved the fundamental question facing them: whether the shock has ended or merely paused.

This week’s major central banks are still likely to hold. Their communications will determine whether those holds represent confidence in the existing stance or preparation for the next increase.
