United States Natural Gas Fund Lowers ISDA Termination Trigger to $200 Million With Société Générale
United States Natural Gas Fund (UNG) amended its ISDA agreement with Société Générale, lowering the Total Net Assets Decline Event threshold to $200M from $1.5B, effective Oct 13, 2026. The change aims to align risk triggers with the fund's current asset levels and reduce unintended termination events.
How this was made

The 30-second read
Why it matters
By reducing the Total Net Assets Decline Event threshold to $200 million, the fund aims to better align risk triggers with current asset levels and reduce the chance of an Additional Termination Event without a credit event.
Market read
This is a derivatives risk-mechanics update that may slightly reduce tail-risk perception for UNG, but it is not presented as a market-moving cash or performance event.
What to watch
Traders may need to check whether other ISDA events, credit support terms, or additional counterparties impose tighter constraints than the single threshold amended here.
Background
The article describes an amendment to the ISDA 2002 Master Agreement governing derivatives termination mechanics between United States Natural Gas Fund and Société Générale.
Ticker impact
United States Natural Gas Fund amended its ISDA with Société Générale, cutting the Total Net Assets Decline Event threshold to $200 million from $1.5 billion effective Oct 13, 2026.
Likely limited near-term impact on UNG price, but could modestly reduce perceived credit/derivatives termination risk versus the prior threshold.
The change is a risk-trigger mechanics update rather than a cash-flow or NAV catalyst, and the article provides no immediate market reaction or UNG-specific performance figures.
Market effects
Highlights how commodity ETPs manage derivatives termination triggers as portfolio size changes, which can affect perceived counterparty risk in the space.
No direct regional market linkage indicated.
Limited, as the event is specific to one fund’s ISDA mechanics with a single counterparty.
Counterpoint
Because the amendment is described as avoiding inadvertent triggers absent a credit event, it may not materially change actual termination probability in practice.
