据普氏能源资讯7月9日伦敦报道，伦敦能源经纪人协会周二公布的数据显示，6月份欧洲天然气场外交易量较上月略有下降，但仍保持了较上年同期强劲的趋势。

6月天然气场外交易总量为3047亿千瓦时，为今年以来的最低水平，较5月下降3%，但仍较上年同期增长10%，主要原因是荷兰天然气交易中心交易量继续增长。

的确，6月份TTF的流动性为2096亿千瓦时，低于上月的2151亿千瓦时，但较上年同期增长30%。

2019年上半年，TTF交易量预计将创下历年新高，2019年上半年，该中心的交易量将达到14052亿千瓦时，而2018年1月至6月，该中心的交易量为10578亿千瓦时。

然而，在英国的NBP交易中心，6月份的交易量为400亿千瓦时，为至少自2011年以来的第二个单月最低水平——只有去年12月的325亿千瓦时，低于上月。

NBP的流动性环比下降11%，同比下降41%，2019年上半年交易量为3,007亿千瓦时，同比下降26%左右。

其他方面，流动性环比略高，欧洲其他天然气枢纽6月份的总水平为551亿千瓦时，高于5月份的544亿千瓦时，较上年同期增长16%。

奥地利VTP交易中心的交易量仍接近历史高点，上月成交65亿千瓦时。意大利PSV中心的流动性本月增长19%，至131亿千瓦时，同比增长56%。

LEBA的数据显示，2019年上半年，欧洲场外交易的总流动性为20686亿千瓦时，同比增长18%。在2018年和2017年分别占交易总量63%和54%的基础上，TTF枢纽占据了交易总量的68%。

NBP枢纽仅占总量的15%，低于2018年的21%，更低于2017年的28%。

OTC European gas liquidity down 3% on month, climbs 10% on year

European natural gas over-the-counter traded volume posted a mild loss on the month in June, but continued its trend of stronger results on an annual basis, data released Tuesday by the London Energy Brokers' Association showed.

Total OTC gas trade stood at 3,047 TWh for June, the lowest for a calendar month so far this year and a 3% fall from May, but still stood 10% higher on an annual basis on the back of continuing increases on the key Dutch TTF hub.

Indeed, TTF liquidity came in at 2,096 TWh in June, down from the 2,151 TWh seen during the previous month but 30% higher on an annual basis.

TTF traded volume for the first half of 2019 indicated that the hub is set to see record high volume for a calendar year, with the H1 2019 period seeing a total of 14,052 TWh traded compared to the 10,578 TWh from the January-June, 2018, period.

However, on the UK's NBP hub, traded volume in June of 400 TWh was the second lowest for a calendar month since at least 2011 -- only the 325 TWh seen in December last year was lower than last month.

NBP liquidity fell by 11% on the month and by 41% on the year, with H1 2019 traded volume of 3,007 TWh about 26% lower when compared to the first six months of last year.

Elsewhere, liquidity was slightly higher on a monthly basis, with other European gas hubs combined coming in at 551 TWh in June against the 544 TWh in May and standing 16% higher on an annual basis.

Traded volume on the Austrian VTP hub remained close to record highs with 65 TWh traded last month. Liquidity on the Italian PSV hub posted increases of 19% on the month and 56% on the year to 131 TWh.

In total, European OTC liquidity for the first half of 2019 stood at 20,686 TWh, an increase of 18% on an annual basis, according to LEBA. The TTF hub accounted for 68% of the total traded volume after having accounted for 63% in 2018 and 54% in 2017.

The NBP hub accounted for a mere 15% of the total, down on the 21% from 2018 and further behind the 28% from 2017.
