For a description of some of the risks and uncertainties that may affect our future results, you should see the “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023 and subsequent Quarterly Reports on Form 10-Q.
Overview
Our results for the three months ended June 30, 2024, were impacted by continued softness in the global metallurgical and thermal coal markets and oversupply in domestic thermal coal markets. Despite this continuing softness, coal markets, particularly high-quality coking coal markets, have remained above previous long-term average levels. Economic growth remains constrained, particularly in Europe and the Americas, due to stubborn inflationary pressure. Although some developed nations’ central banks began easing monetary policy during the current quarter, the United States has maintained its tighter monetary policy. Slower economic growth negatively impacts end user demand for our products and has a negative impact on coal markets.
Over two years since the February 24, 2022, Russian invasion of Ukraine, the war continues with no indication any resolution is close. Major changes in energy trading patterns appear to be set while hostilities continue. Bans on the import of Russian coal by the European Union, the United Kingdom, Japan, and other nations continue to drive Russian coal into China, India, Turkey, and other Asian countries. These destinations have generally sourced Russian coals at discounts, sometimes significant discounts, from what similar quality coals from other origins would have required. We expect continued availability of discounted Russian coal into Asian markets. However, we believe most Russian coal is thermal and lower quality metallurgical and that the availability of high quality Russian coking coal is limited.
During the year ended December 31, 2023, China effectively lifted the ban on imports of coal from Australia. While Australian coal is once again flowing into China, their purchases of high-quality coking coal from Australia remain below pre-ban levels. Increased Chinese reliance on domestic production and increased imports of discounted Russian coal and Mongolian coal pressures import volumes from Australia. For the six months ended June 30, 2024, Australian coking coal exports appear to be on track to increase compared to the six months ended June 30, 2023. The increase in availability of Australian coking coal and relative softness in global demand resulted in a rapid decline in Pacific coking coal indices in the six months ended June 30, 2024. Atlantic coking coal indices declined and remain lower as well. We believe that some high cost coking coal sources are currently under economic pressure at current market levels.
On March 26, 2024, a large container vessel lost power and struck one of the main support piers of the Francis Scott Key Bridge, plunging most of the span into the water and effectively blocking shipping access to Baltimore Harbor. One of the primary coking coal loading ports we use for loading export coal, the Curtis Bay Terminal (CBT), was blocked until the debris was removed and the main shipping channel was reopened on June 10, 2024. We worked diligently with our logistics partners to effectively maximize available throughput at our other primary coking coal loading port, Dominion Terminals Associates (DTA), in which we have a 35% ownership interest. We also contracted with a mid-streaming service to utilize some CBT capacity through the use of shallower draft temporary shipping channels that were opened prior to the main channel reopening. This allowed us to minimize negative impacts to our coking coal shipment volumes and to our customers, however, did negatively impact our profits by more than $12 million during the three months ended June 30, 2024.
With respect to the global coking coal market, we believe that underinvestment in the sector in recent years underlies longer-term market dynamics. Overall, underinvestment in the sector appears likely to persist, as government policies and diminished access to traditional capital markets limits investment in the sector. Additionally, recent reports of new supply disruptions may also support these markets. The duration of specific supply disruptions is unknown. In the current macroeconomic environment, we expect coking coal prices to remain volatile. Longer term, we believe continued limited global capital investment in new coking coal production capacity, normal reserve depletion, and an eventual return to economic growth will provide support to coking coal markets.
During the six months ended June 30, 2024, domestic thermal coal consumption was pressured by a generally mild winter heating season in most of the heavily populated areas of the United States, low power demand, low natural gas prices, increased subsidized renewable generation, and high utility coal stockpiles. Currently, natural gas prices are at
