A 3.1 per cent average with diesel at 19.6 per cent

Consumer prices in South Korea rose 3.1 per cent from a year earlier in August, according to the Ministry of Data and Statistics, after a 2.8 per cent on-year rise in July. The headline stayed above 3 per cent. The pickup reversed a slowdown in July and came alongside elevated global crude prices. Korea stands as an energy importer exposed to the oil market; the published figure is a basket average, and which item lands in which household's outgoings remains unread in the headline.[1]

Fuel prices sat at the front of that August increase: in the Ministry of Data and Statistics basket, diesel rose 19.6 per cent and gasoline 11.5 per cent. Mobile subscription charges also pushed the basket higher; they are measured against heavily discounted rates a year earlier, so part of the 3.1 per cent is a comparison against last year's fees rather than a new pump price. Korea imports almost all of its oil and relies heavily on imports to meet its energy needs, and the fuel component carries the Middle East supply disruption straight into domestic prices. A pump price and a base effect sit side by side in the same headline.[1]

A 3.19 per cent rate with 1.13 points from food

Annual inflation in Indonesia reached 3.19 per cent in August, up from 2.88 per cent in July, Statistics Indonesia (BPS) official Ateng Hartono said on Tuesday, and the rate stayed inside the government and Bank Indonesia target of 2.5 per cent plus or minus 1 percentage point. Core inflation, which strips out volatile food and administered prices, stood at 2.92 per cent. Volatile food inflation reached 4.06 per cent and inflation in government-administered prices was 3.32 per cent. Indonesia's House of Representatives approved a new Bank Indonesia governor as the figures were published. Remaining inside the target band does not say which line in the basket swelled.[2]

Food, beverages and tobacco rose 3.86 per cent from a year earlier in the BPS basket and contributed 1.13 percentage points to the headline rate. Chicken, fresh fish, cooking oil, rice, cigarettes, bird's eye chilli, beef and red chilli were named among the main food contributors. Transportation prices rose 4.79 per cent, with gasoline prices, airfares, engine lubricants, motorcycles and cars on the list. Personal care and other services was the fastest group at 9.25 per cent, with gold jewelry prices among the items in that group. The same 3.19 per cent therefore gathers a kitchen list and a jewelry line under one headline.[2]

Two nearby headlines, two different bills

The two August rates sit close together: 3.1 per cent in South Korea, 3.19 per cent in Indonesia, and both followed a July slowdown. The items that moved do not sit close together. In the Ministry of Data and Statistics basket the large moves are diesel at 19.6 per cent and gasoline at 11.5 per cent; in the BPS basket the largest named contribution is 1.13 percentage points from food, beverages and tobacco, while gasoline appears again inside the 4.79 per cent transport line. Diesel and gasoline are a pump price; chicken, rice and cooking oil are a kitchen price; gold jewelry sits in a different group. The headline averages those lines. Another reading is available: both rates may be picking up the same oil-price impulse through fuel and transport, with Indonesia's food list as a separate local movement.[1], [2]

A rate that stays inside a 2.5 per cent plus or minus 1 point target, or that holds above 3 per cent, still does not say which income band paid for diesel, rice or gold jewelry. The Ministry of Data and Statistics and BPS releases name items, not income bands, and neither release carries a wage series beside them. If the next consumer-price releases from the Ministry of Data and Statistics and BPS keep the same item breakdown, the next readable signal is whether diesel and gasoline annual rates remain the large lines inside the CPI, and whether the food, beverages and tobacco contribution and the 4.06 per cent volatile-food rate remain the kitchen side of the headline.[1], [2]
