China LNG Import Cost Index at 176.97 as Asian September Demand Heads for Eight-Year Low
Kpler projects regional September LNG intake at 20.09 million tons, the weakest since 2018, as elevated JKM prices continue to suppress Chinese spot buying.
Asian LNG imports are on course for the weakest September in eight years, with regional volumes projected at 20.09 million tons this month against 22.27 million tons in September last year, according to Kpler vessel-tracking data cited by Reuters correspondent Clyde Russell on September 16 (2026-09-16). China's LNG comprehensive import CIF price index, published by the Shanghai Petroleum and Natural Gas Exchange, registered 176.97 for the week of September 7 to 13, reflecting the elevated acquisition costs weighing on spot buying across the region.4
JKM, the Asian spot LNG benchmark, stood at $27.51 per million British thermal units as of September 20. At prices near that range, Chinese buyers have historically wound down discretionary spot purchasing and drawn instead on domestically produced gas or contracted volumes. The pricing range that triggers Chinese accumulation remains well below current JKM levels, keeping incremental demand subdued through the month.4
The trend was already apparent in August. China's LNG imports were running 18% below year-earlier levels that month, OilPrice.com reported on August 31 (2026-08-31), ending a three-month run of year-on-year gains that had accumulated over the summer. With the September Kpler projection pointing in the same direction, demand restraint now appears to be a sustained response to price levels rather than a single-month adjustment.3,4
Wood Mackenzie described the underlying shift as structural in June (2026-06-05). The consultancy's analysts said China was departing from its role as a predictable demand absorber, evolving into a buyer that times LNG volumes against prevailing price conditions — stepping up purchases when prices ease and pulling back when they do not. The pricing environment since mid-year has kept volumes in check.1
The regional picture extends beyond China. Analysts cited by Reuters put the likely annual decline in Asian LNG demand at between 3% and 10% in 2026, which would be the second consecutive annual drop for a region that generated most of global LNG demand growth over the prior decade. Northeast Asia accounts for the bulk of the shortfall, and the September Kpler data appears to track toward the sharper end of that forecast range.4
PetroChina's first-quarter 2026 results illustrate how Chinese state gas companies are managing the pricing environment. The company sold 93.891 billion cubic meters of gas in the first three months of the year, up 6.9% from 87.869 billion cubic meters in the same period of 2025, while natural gas operations generated operating profit of RMB18.867 billion, up RMB5.359 billion year-on-year. Domestic sales growth absorbed some of the margin pressure from elevated import procurement costs.2
One positioning signal runs against the bearish demand picture. JKM supply-side exposure has carried a bullish cast, with some participants apparently expecting tighter available tonnage to sustain prices regardless of Chinese demand weakness. Sustained European winter storage demand adds to that dynamic: TTF front-month gas stood at €79.54 per megawatt-hour as of September 20, and continued strong European draw would leave fewer flexible Atlantic LNG cargoes available to rotate toward Asia.4,1
September customs data from China, expected in the coming weeks, will be the sharpest test of the Kpler projection. If monthly volumes confirm a reading below 2025 levels, it would validate the Wood Mackenzie price-response model and indicate Chinese spot buying will remain limited until JKM moves substantially below its current $27.51. Buyers watching the October-delivery window will have a clearer picture once the September tallies come in.4,1
