Economy in Brief

Expanding over all horizons based on median and average data Over the last 12 months and six months, the composite PMI data show mostly setbacks–weaker performance–across the various 25 countries and regions that report in this table. However, over no horizon is there more than 8 of the 25 reporters showing an outright decline in terms of PMI values (readings below 50). Over the recent three months, more significant advances have been recorded. Only 21.7% of the reporters show weakening in their average performance over three months compared to six months. This is a sharp contrast with 82.6% weakening over six months compared to 12 months, and even the 52.2% that shows weakening over 12 months compared to 12 months ago. The six-month comparison is a geopolitically difficult comparison.

Progress, yes – but will it endure? Progress is in gear. The last three months of month-to-month PMI readings yield median PMI values of 52.2 to 52.5 to 52.3 moving from July to September. September shows a slight backtracking, but all readings are above a diffusion value of 52. Averages show better growth transition from 52.1 to 52.4 to 52.8 on the same time sequence. Using averages we see a strengthening trend.

The US, UK, and EMU as an unweighted group also show progressive improvement. This group shows irregular improvement from 12 months to six months to three months, but the three-month diffusion average is higher than the 12-month average.

Among the 25 reporters surveyed, eleven have percentile standings over the last 4½ years of data that are below their respective medians; that’s a lot. So, there is still a considerable proportion of reporters with weak queue percentile standings on the standards of about the last five years–years that have not been terribly strong.

Summing up The good news in this report is the breadth of improvement in September, with only five reporters below a diffusion reading of 50, indicating contraction and with 60% of the reporters showing month-to-month improvement.

In this week's Letter, we examine how a strengthening El Niño is adding a food and weather shock to an Asia already absorbing an oil shock. El Niño is now in full swing, with the Southern Oscillation Index at its lowest in over two decades, and its fullest effects may only arrive next year (chart 1). Food prices are already turning up, and food price levels have risen most in India, the Philippines, Vietnam and Indonesia (chart 2). That adds a second source of inflation on top of the oil price surge that followed the disruption of shipping through the Strait of Hormuz. On the supply side, drought is hurting rice producers just as fuel and fertiliser costs climb, raising the risk of a significant negative supply shock. The most exposed are net rice consumers with thin stocks, such as the Philippines (chart 3). India shows how quickly conditions can deteriorate: its monsoon ended with its largest deficit since 2015, and reservoir storage has slipped below normal (chart 4). The effects reach beyond food. Drier conditions have fed peat and forest fires in Indonesia, pushing Singapore's air quality into the unhealthy range for the first time since 2023 (chart 5). For policymakers, El Niño adds food security, water security and inflation management to a list already crowded by the energy shock and geopolitics. The most agriculture-reliant economies, India, Indonesia and Vietnam, face a double hit to growth and prices (chart 6). Should food inflation force central banks to tighten further, the growth cost would rise again.

El Niño and food prices El Niño is now in full swing. The Southern Oscillation Index has plunged to around -2.7 on a three-month average basis, its lowest reading in over two decades and below even the 2015 trough (chart 1). Ocean temperatures tell the same story. The Niño 3.4 index, the main gauge of El Niño, tracks sea surface temperature anomalies in the central and eastern equatorial Pacific. A sustained reading of +0.5°C or more signals El Niño conditions, while readings above +1.5°C mark a strong event. The index reached +1.8°C in August, and the event is expected to persist into 2027. Its fullest effects may therefore only emerge next year, as weather damage to harvests feeds through to food supply with a lag. Food prices are already moving. Growth in the FAO Food Price Index has turned up to around 6% y/y, partly reflecting El Niño weather effects on crops. With food carrying a heavy weight in consumer baskets across emerging Asia, a sustained rise in global food prices would quickly find its way into regional inflation.
