Gas rebalancing 1: Clearing the global gas glut
Published by Callum O'Reilly,
The global gas market has been shocked by the pace and scale of transition from boom to bust. At the beginning of 2014, suppliers were paying a lofty US$20/million Btu for LNG in a market that was anticipated to remain tight for years. By early 2016 producers were struggling to sell surplus cargoes for US$5/million Btu, 75% below the levels of just two years earlier. A bust of these epic proportions was not supposed to happen.
The initial shock has now passed and gas market consensus has digested the phenomenon of a state of global oversupply. But global demand growth remains sluggish and supply continues to grow. More than 50 billion m3/yr of new LNG liquefaction capacity has been commissioned since 2014. In addition, there is a visible pipeline of at least another 150 billion m3/yr of committed new capacity coming to market by 2020.
But as the dust from the bust starts to settle, attention is shifting to some key questions. How will the global market clear the evolving gas glut? And how will this impact the evolution of pricing dynamics and the gas market investment cycle?
Almost everyone in the gas and power industries has a vested interest in the answers to these questions, either explicitly or implicitly. In the next two articles, Timera Energy sets out its take on the answers.
Global market rebalancing series
Rebalancing of the global gas market is a complex area with a heavy dose of uncertainty. But it is the authors view that the drivers behind market rebalancing can be broken down via a relatively simple logic. The authors have set out their thesis on:
- The market mechanisms that will clear the current gas glut.
- The path to global gas price recovery and why this may start sooner than expected.
- They will do this as much as possible using a practical scenario illustration of the evolution of global supply and demand volumes and regional gas prices.
In this article, the authors focus on the key price/volume mechanisms that they believe will interact to clear the current market glut.
Evolution of the global market balance
In a nutshell, the current global oversupply of gas is the result of new LNG supply outpacing demand growth. Investment decisions in new liquefaction capacity earlier this decade were based on overly optimistic forecasts of demand growth, particularly in emerging Asian markets. The legacy of these decisions is still feeding through in the form of committed new supply, given relatively long delivery lead times for new liquefaction projects (approximately five years).
This overhang of surplus LNG is the primary driver behind the current global oversupply of gas. There are important domestic gas market dynamics at work behind this within regional markets across Asia, Europe and North America. But understanding how the global surplus of LNG can be cleared is a key starting point.

There is a cascading logic to the progression of the charts:
- Top chart: in the top chart, a combined LNG market balance for non-European LNG importing nations is shown. These consist of Asian importers plus ‘other’ smaller importers, predominantly in South and Central America. ‘Asian and other’ buyers typically have first call on global LNG supply, given demand is dominated by less flexible buyers with long-term contracted volumes and LNG specific import requirements.
- Middle chart: the middle chart shows how LNG sits in the aggregate European gas market balance. Europe is broken out separately from other markets because it has liquid hubs, alternative supply sources and relatively flexible LNG supply contract structures. This means Europe plays an important role as a swing market to help clear the global LNG balance. Any surplus or deficit of LNG from the top chart (‘Asian and other’) can be thought of as cascading down into the European market.
- Bottom chart: supply volumes in the top two charts assume LNG liquefaction capacity operates at full target production levels. Demand volumes assume ‘business as usual’ demand based on current market price levels. Any surplus or deficit of LNG that cannot be absorbed via European market swing flexibility under these conditions, creates a global LNG imbalance (surplus or deficit) shown in the bottom chart.
For simplicity, the North American gas market is not explicitly shown in these charts, primarily because it is largely gas self sufficient (i.e. a net exporter of LNG). The US market, however, plays a very important implicit role in clearing an oversupplied global market which we set out in more detail below.
As growth in new LNG liquefaction capacity outpaces demand growth over the next three years, a growing global surplus of LNG emerges over and above ‘business as usual’ Asian & European requirements. The surplus in this scenario, peaking at 68 billion m3/yr (49 million tpy) in 2019, is represented by the red shaded ‘LNG glut’ triangle in the second and third charts.
The scale of the LNG glut is actually relatively small (e.g. vs aggregate European demand). But even small volumes of oversupply can induce big price moves in order to induce an adequate market clearing response. It is important to note that while this glut triangle is a representation of LNG oversupply, the market will always clear. What the triangle illustrates is the incremental supply and demand response required to allow the global market to clear (vs a business as usual scenario). But what are the market mechanisms that act to clear this LNG glut?
Clearing mechanisms at work
Clearing the glut of LNG is about inducing incremental volume response. In other words, it is about inducing market participants to adjust the volume of their production and consumption decisions in response to market price signals.
In the authors’ view, there are four key mechanisms that can drive this. Two of these involve incremental demand response (as a result of lower gas prices) and two involve the ‘shut in’ of price sensitive supply. The four mechanisms are summarised in Table 1 below, along with a range of potential volume response.

There is arguably a fifth clearing mechanism in the form of Russian production flexibility. The reason that this has not specifically been broken out is that the authors assume that through the duration of the LNG glut, Russian acts to maintain its European market share (at around 150 billion m3/yr) rather than responding to prices. This is consistent with historical behaviour.
The scenario summary on how the four mechanisms interact to clear the LNG glut is shown in Figure 2.

European power sector switching
Clear evidence is emerging in 2016 of European power sector demand response to lower gas hub prices. Combined Cycle Gas Turbine (CCGT) load factors in gas dominated power markets such as the UK and Italy have risen substantially year on year. Even Continental power markets dominated by cheaper coal plants have seen switching to CCGTs over the summer.
There are two important price drivers behind this switching. A weakening of gas hub prices, caused in part by a steadily growing flow of LNG imports. Coal prices have also been recovering in 2016, lowering the gas price hurdle required to induce higher CCGT load factors.
European power sector switching is currently a key driver of marginal pricing dynamics across European hubs. In the authors’ view, it will also be an important clearing mechanism as the LNG surplus grows (2016 - 2019). Timera Energy set out here why it thinks that there may be up to 30 - 40 billion m3/yr of potential switching demand response in Europe. Some of this switching volume may end up being permanent, with weakening coal plant economics resulting in the closer of older coal assets (as is happening already in the UK).
Asian demand response
In theory, Asian buyers should also be able to respond to falling LNG prices by increasing import demand volumes. But the practical evidence of this is so far limited. Despite a 50% fall in Asian LNG spot prices from 2014 to 2015, Asian LNG demand actually fell 4%.
Practical opportunities for physical substitution of gas for other fuels (e.g. coal and oil) are relatively limited. Some markets also face regas import capacity constraints. But most importantly, demand response is hampered by a lack of transparent market price signal mechanisms to induce the purchase of higher LNG volumes.
Asian LNG purchasing strategies tend to be driven by national policy and domestic portfolio considerations, in markets that consist largely of captive end users. Under these conditions, the emergence of LNG demand response to lower prices is likely to have both a gradual and a limited impact in clearing the LNG glut.
Australian LNG exports shut in
There is some speculation that low spot prices may induce a reduction in export volumes from the three Queensland liquefaction terminals (QCLNG, APLNG, GLNG) that have been developed based on coal bed methane (CBM) feedgas. The logic here is that exports are uneconomic if netback spot prices do not cover feedgas costs.
The most vulnerable of the three projects to export volume reductions is the Santos GLNG terminal given a shortage of feed gas relative to export capacity. If Santos needs to purchase incremental feedgas, it has a clear cost base against which exports may be reduced. But in practice this volume is relatively small and may not exceed the level of long-term contract cover (approximately 85%).
In the authors’ view, Australian exports under long-term contract that are backed off by CBM feedgas resource are less likely to be shut in. CBM production cost signals are relatively complex. There is also an environmental angle to ramping down production given a powerful domestic anti-fracking lobby (led by the agricultural sector). These factors suggest to us that disruptions to targetted production levels are likely to be limited.
US LNG exports shut in
The US is a different story to Australia. The cost base of LNG terminal feedgas is driven by a liquid and transparent price signal in the form of Henry Hub. LNG export contract structures are also highly flexible in their ability to respond to price signals.
As long as netback spot prices cover the variable costs of Henry Hub, liquefaction and transport, LNG will flow out of the US. But if netback spot prices (e.g. in Europe and Asia) fall below this hurdle, then US LNG will be shut in. US shut ins are likely to be highly price responsive i.e. within a US$1/million Btu range in netback spot prices, there could be upwards of 80 billion m3/yr of shut in volume response by 2020.
As a result, the authors view US shut ins as the backstop global clearing mechanism for the evolving LNG supply glut. In other words it is US LNG flexibility that can provide whatever additional volume response is required over and above the other three clearing mechanisms.
How do clearing mechanisms interact to clear the glut
The scenario set out above shows an LNG supply glut of 68 billion m3/yr (49 million tpy) evolving by 2019 as new liquefaction capacity outpaces demand growth. Of the four sources of incremental volume response, the authors anticipate European power sector switching and US shut ins interacting to play the most important role.
US shut ins are likely to play a particularly important role as the marginal clearing response mechanism in the global market given their sensitivity to price signals. If the supply glut turns out to be less severe than shown in the scenario, then a lower volume of US LNG shut ins is required. If the glut is more substantial, then higher volumes of US shut ins are needed to make way for less flexible supply sources. This balancing role of US export flows significantly increases the importance of Henry Hub in driving global gas pricing dynamics (something we come back to next week).
It is the authors’ view that the current LNG glut is more of a 5 year than a 10 year phenomenon. There are important structural factors eroding the LNG surplus, as well as the market response mechanisms described above. These include declining European production, emerging Asian demand growth and the current hiatus of investment in new supply.
There is currently a strong industry focus on the immediate issues of a deepening supply glut. But rebalancing and recovery may not be that far out of sight, particularly given a 5+ year lead time to develop new LNG supply.
So how does the path to recovery look? What happens to global gas prices as the market rebalances? What are the implications for portfolio exposures and the gas investment cycle? These are questions that will be addressed in the second part of this article, as the authors look beyond the current glut at the three phases of market recovery.
The second part of this article, ‘Gas rebalancing 2: the path to price recovery’, will be available soon.
