Iggy's Journal: Inflation Ticks Up for a Third Straight Month. The STI Barely Noticed.
23 September 2026, Evening
(No infographic for this post; I'm on a plane right now)
The STI closed at 5,709.9, down 13.85 points, a quiet 0.24 percent day. Underneath that quiet, Singapore just posted its highest core inflation reading in two years, and the room is genuinely split on what MAS does about it in October.
The Numbers
Core inflation rose to 2.2 percent in August from 2 percent in July, the third straight monthly increase, while headline inflation, which includes accommodation and private transport, ticked up to 2.3 percent. Airline ticket costs jumped 12.9 percent, the sharpest rise in nearly four years, and services inflation climbed to 2 percent from 1.7 percent the month before. MAS already tightened the SGD NEER slope twice this year, in April and again in July, and economists are now split on whether October brings another small tightening or a hold. DBS's Chua Han Teng summed up the tension in four words, inflation "firmed but not accelerating."
My Personal Take
Barclays called this data "more benign" than what MAS was pricing in back in July, and I think that's the real story hiding under a boring index day. The central bank tightened twice this year on the expectation that growth would eventually show up as inflation. Now the inflation is showing up, just slower and milder than the move that was meant to get ahead of it. That's not a policy mistake, it's a central bank managing a moving target in real time, but it does mean the case for October restraint gets a little stronger with every print like this one. If your T-bill or fixed deposit is coming up for renewal around then, this is exactly the kind of data that decides whether your next rate looks better or worse than the last one.
Cheers, Iggy
