Policy pulse
The inflation rate remains well above the central bank’s 3% target, reinforcing the need for continued monetary tightening. The recent rate hikes have yet to fully temper inflation expectations, which remain elevated. The central bank’s forward guidance signals a cautious approach, balancing growth risks with inflation control.
Market lens
Immediate reaction: The ST currency (STD) weakened 0.4% against the USD within the first hour, while 2-year government bond yields rose 15 basis points, reflecting increased inflation risk premiums. Breakeven inflation rates edged higher, signaling market skepticism about near-term disinflation.
Core macroeconomic indicators provide context for the inflation surge. GDP growth for Q3 2025 slowed to 1.2% quarter-on-quarter, down from 1.8% in Q2, indicating cooling demand. Unemployment held steady at 5.4%, suggesting labor market tightness that supports wage growth. Wage inflation accelerated to 6.3% YoY, feeding into consumer prices.
Monetary Policy & Financial Conditions
The central bank has raised its policy rate by 125 basis points since early 2025, reaching 5.5%. Financial conditions tightened, with credit spreads widening and lending standards becoming more restrictive. However, real interest rates remain negative due to high inflation, limiting the dampening effect on consumption and investment.
Fiscal Policy & Government Budget
Fiscal deficits narrowed slightly to 3.2% of GDP in the first half of 2025, aided by improved tax collections amid inflationary gains. Yet, government spending remains elevated, especially on subsidies and social programs aimed at shielding vulnerable populations from price shocks. This fiscal stance may complicate inflation control efforts.
Drivers this month
- Shelter inflation accelerated sharply, reversing a three-month slowdown.
- Food prices rose due to adverse weather impacting crop yields.
- Energy prices stabilized but remain historically high.
Policy pulse
The inflation trajectory complicates the central bank’s path. The recent uptick may prompt additional rate hikes or extended tightening, especially if wage growth remains robust.
Market lens
Immediate reaction: The STD currency depreciated 0.4%, while 2-year yields jumped 15 bps, signaling heightened inflation risk. Breakeven inflation rates rose 10 bps, reflecting market concerns over persistent price pressures.
This chart signals a reversal of the mid-year inflation decline, trending upward again. The persistence of double-digit inflation suggests entrenched price pressures, requiring vigilant policy responses to avoid a wage-price spiral.
Looking ahead, inflation in ST faces a complex interplay of forces. The baseline scenario (60% probability) envisions inflation moderating gradually to 8-9% by mid-2026, supported by tighter monetary policy and easing supply constraints. The bullish scenario (20%) sees inflation falling below 7% if global commodity prices decline sharply and fiscal consolidation accelerates. Conversely, the bearish scenario (20%) projects inflation rising above 13% if geopolitical tensions disrupt energy supplies or wage pressures intensify.
External Shocks & Geopolitical Risks
Heightened geopolitical tensions in key commodity-exporting regions threaten supply stability. Any escalation could exacerbate energy and food price inflation, complicating domestic inflation control efforts.
Structural & Long-Run Trends
Structural inflation drivers include persistent supply chain bottlenecks, demographic shifts increasing housing demand, and evolving labor market dynamics. These factors suggest inflation may settle at a higher long-run baseline than pre-pandemic levels.
The October 2025 inflation print for ST underscores the challenges ahead. While monetary and fiscal policies aim to rein in price pressures, external shocks and structural factors pose risks to disinflation. Market reactions reflect uncertainty, with currency weakness and rising yields signaling inflation risk premiums. Policymakers must balance growth and inflation control carefully to avoid stagflation. Investors should monitor inflation-linked assets and central bank signals closely.
