Inpex gains long-term LNG deal and oil-price boost, but faces Kazakhstan fine risk

  • 15-year LNG sales deal with ADNOC Inpex signed a 15-year deal to buy 1 million tonnes of LNG per year from ADNOC's Ruwais project starting 2028. This locks in long-term supply, supporting future revenue and reducing demand uncertainty for Inpex's gas business.

    This is a major new contract that directly boosts Inpex's long-term earnings visibility.

  • Kazakhstan $4.8 billion environmental fine Kazakhstan may enforce a $4.8 billion environmental fine against the Kashagan oil venture, which includes Inpex. The operator is fighting it in arbitration, but enforcement could start after July 20, creating a large potential liability and regulatory risk.

    This is a new legal and financial threat that could hurt Inpex's profits and investor confidence.

  • Middle East tensions push oil prices higher Attacks on Saudi tankers near the Red Sea and fears of a double blockade of Hormuz and the Red Sea have raised oil prices. As an oil and gas producer, Inpex benefits because higher crude prices increase its revenue and profit.

    This is the main short-term price driver, directly lifting Inpex shares.

  • BP joins Bab Gas Cap, confirming project strength BP bought a 10% stake in ADNOC's Bab Gas Cap project, where Inpex is a partner. This shows the project is attractive and well-funded, which supports Inpex's stake value and future gas production.

    It reinforces the value of Inpex's existing gas asset and partnership.

INPEX Raises Ichthys LNG Stake to 68.555% After Exercising Pre-Emptive Rights

Japan's INPEX has agreed to acquire an additional 0.735% interest in the Ichthys LNG project in Australia from subsidiaries of JERA, lifting its participating interest from 67.82% to 68.555% subject to Australian regulatory approvals. The acquisition covers JERA's interest in offshore blocks WA-50-L and WA-51-L, which contain the Ichthys gas-condensate field, as well as its stake in Ichthys LNG Pty Ltd, the company that owns the project's export pipeline and downstream liquefaction facilities. The deal stems from JERA's December 2025 agreement to sell its Australian project subsidiary, including the 0.735% Ichthys interest, to MidOcean Energy, and INPEX elected to exercise its pre-emptive rights over the stake under the project's joint operating and shareholder agreements. Ichthys, operated by INPEX, has LNG production capacity of around 9.3 million metric tons per year, alongside approximately 1.65 million tons of LPG and peak condensate production of about 100,000 barrels per day, with production having begun in 2018. Sales contracts cover about 8.4 million tons of annual LNG production, with roughly 70% destined for Japanese buyers, and annual Ichthys output is equivalent to more than 10% of Japan's LNG imports. The purchase continues INPEX's gradual consolidation of Ichthys, following its 2024 agreement to acquire Tokyo Gas' 1.575% interest, which raised its ownership from 66.245% to the current 67.82%, and INPEX said the additional JERA stake fits its Vision 2035 strategy and expects only a minimal effect on its consolidated financial results.

Japanese Executives Call for a Stable Yen as Kawasaki Weighs Moving Production Home if It Hits 150

Japanese corporate executives are calling for a stronger and more stable yen, saying that currency volatility makes it hard for companies to plan costs and production. Yoshinori Kanehana, chairman of Kawasaki Heavy Industries, told CNBC during the Gastech conference on Tuesday, September 15, that if the yen remains volatile the company cannot formulate strategy, and that if the yen strengthens to 150 per dollar, the company may consider moving production back to Japan from the United States. Kawasaki Heavy Industries currently has 27 plants outside Japan, including in the United States, and another 17 plants in Japan. Takayuki Ueda, president and CEO of Inpex, said that a yen level of 100 per dollar is appropriate and consistent with the state of the Japanese economy, even though nearly 90% of Inpex's business is conducted outside Japan and is mainly denominated in US dollars. Inpex's revenue fell in the first six months of the year on lower crude oil sales volumes, but the yen's 6.7% depreciation to 158.37 per dollar helped offset part of the revenue decline. Meanwhile, Takeshi Hashimoto, president of Mitsui O.S.K. Lines, said last week that he wants to see a stable currency market and would be comfortable if the yen were at 150 to 155 per dollar. The yen was trading at 156.3 per dollar on Thursday, September 17, compared with an average exchange rate of about 123 per dollar over the past 10 years. A Bank of Japan survey showed that Japanese businesses expect the yen to average 152.51 per dollar in the second half of this year.

INPEX raises full-year net profit forecast to 510 billion yen, lifts dividend to 112 yen

INPEX has revised its consolidated net profit forecast for the fiscal year ending December 2026 upward to 510 billion yen, a 29.5 percent increase from the previous year, compared with the earlier range of 350 billion to 450 billion yen. This exceeds the average analyst estimate of 470.4 billion yen from 11 analysts. The company also raised its annual dividend forecast from 108 yen to 112 yen. The upgrade reflects solid production at the Ichthys LNG project in northern Australia, while revised assumptions for crude oil prices and foreign exchange rates from the third quarter onward are also boosting performance.

INPEX sued by Australian authority for underreporting emissions at Ichthys LNG facility

The environmental protection authority in Australia's Northern Territory has sued INPEX for underreporting emissions from its Ichthys liquefied natural gas facility. According to the authority, INPEX is suspected of violating permit conditions by underreporting benzene and toluene emissions from 2019 to 2024. The lawsuit follows INPEX's announcement last October of significant underreporting at the facility, after which regulators conducted a review of operations at the Ichthys LNG facility and Santos' Darwin LNG facility, leading to the approval in July of 23 recommendations for tighter regulations, including the installation of continuous emissions monitoring systems. The regulator plans to draft amendments to existing permits this month to reflect these changes.

Nikkei Average Opens 838 Yen Lower, Disco and SoftBank Group Decline

On the 24th, the Nikkei Average opened lower, falling 838.35 yen to 65,584.25 yen. The sharp continued decline of major indices in the US stock market the previous day weighed on sentiment, while rising crude oil prices due to escalating tensions in the Middle East and an increase in domestic long-term interest rates also capped stocks. Meanwhile, although the yen weakened to the 163.80 range against the dollar and there were expectations for the full-fledged start of April-June earnings announcements from major domestic companies, selling dominated at the open. Among the top traded issues on the Tokyo Stock Exchange Prime Market, Disco, SoftBank Group, and Advantest declined, while Takeda Pharmaceutical and INPEX rose.

Growing concerns over a double blockade of the Strait of Hormuz and the Red Sea

Yemen's Iran-backed Houthi group announced it attacked two Saudi oil tankers near the Bab el-Mandeb Strait in the Red Sea, heightening fears of a double blockade that would affect safe passage through both the critical energy chokepoint of the Strait of Hormuz and its alternative route, the Red Sea. In light of this development, energy-related companies such as INPEX, Japan Petroleum Exploration, JGC Holdings, and Chiyoda Corporation are likely to draw attention.

Kashagan oil majors to contest $4.8 billion Kazakhstan environmental fine

Kazakhstan’s government said it may enforce a roughly $4.8 billion environmental fine against the North Caspian Operating Company after July 20, while the operator said the move is prohibited under ongoing arbitration proceedings. The Justice Ministry warned that enforcement measures could include an additional penalty of 10 percent of the recovered sum. NCOC, a joint venture of KazMunayGas, Shell, TotalEnergies, Eni, Exxon Mobil, CNPC, Inpex and others, said an international arbitration tribunal has issued a restraining order blocking enforcement while the case is pending. The operator and its contracting companies reject the fine and the underlying allegations, but the Kazakh energy ministry said the arbitration does not prevent enforcement. The Kashagan field in the Caspian Sea is one of the world’s largest recent oil discoveries, holding an estimated 13 billion barrels of recoverable reserves.
