The United States has removed its export ban on American jet engine parts and technology to China. This decision permits GE Aerospace to continue supplying components to China’s state-owned aircraft manufacturer, Comac.

This move, alongside the relaxation of export controls on chip design software, suggests a broader trend of reducing U.S.-China trade tensions. While GE Aerospace and Boeing have not commented, the U.S. Commerce Department and Comac have yet to issue official statements.

The decision to lift the export ban on jet engine parts and technology supplies to China represents more than a bilateral concession. It unveils a tangible step towards easing commercial restrictions that, just months ago, were tightening with precision. With GE Aerospace now able to resume business with China’s Comac, there is a renewed sense of continuity for existing supply chains that depend on consistent regulatory permissions.

To put it plainly, traders saw prolonged uncertainty following policy measures aimed at curbing the transfer of sensitive technologies. This week’s development changes that trajectory. It implies a softening of enforcement rather than a reversal of strategic goals. From a trading perspective, that distinction matters.

As we interpret this, the decision follows a similar pattern seen with chip design software controls. Stakeholders in complex manufacturing—especially those that rely on multi-national input and expertise—can begin to assess near-term market stability with slightly more confidence. While there’s no official acknowledgement yet from the U.S. Commerce Department or Comac, activity on both sides will likely resume in practice, even if not formally in statement.

For us, the takeaway lies in the pricing of uncertainty. Derivatives markets can now assign slightly less weight to abrupt disruption scenarios stemming from technology-related frictions between these economic powers. Short-dated volatility premiums may moderate, particularly in sectors directly touched by aerospace and semiconductor integration. We don’t expect this to trigger heavy repositioning straight away, but it could affect skew distribution and implied vol spreads over the coming weeks.

Implications For Global Markets

Firms that had paused forward projections or hedging activity around cross-border technology exposure may begin to revisit those models. This is especially true in baskets where aerospace inputs play an embedded but indirect role. There’s likely to be more direction on longer-dated contracts where policy clarity is entwined with production timelines.

This is, however, not a declaration of open trade but more of a tactical move to maintain influence while preserving commercial advantage. Policymakers appear to be exercising strategic selectivity, choosing where relaxation provides benefit without handing over leverage. That’s key to how we interpret the messaging, even in the absence of direct quotes from officials.

Looking ahead, increased liquidity in specific industrial inputs could mean more predictable earnings forecasts for some entities, increasing strike proximity in options pricing. As liquidity calibrates to reflect these restored flows, we’re watching for subtle shifts in traded volume and strike selection around embedded export-sensitive exposure.

We’ve already seen a repricing of terminal rate expectations affect trade across tech-heavy assets; developments like this create another input to model. It doesn’t negate those themes, but it distinguishes short-term movement from structural decoupling. A single export line resumption cannot rewrite strategic containment, but for those with exposure to knock-on sectors, it changes the week-to-week calibration.

Distinctly, this also signals that while rhetoric can remain strong publicly, the administrative apparatus may act more quietly in favour of economic friction management. Volatility traders should measure options behaviour closely, especially around sectors adjacent to aerospace supply. Adjustments in calendar spreads and delta-neutral hedges are likely, particularly as this feeds into broader de-risking or re-risking operations.

We must now pay closer attention to export licence updates, trade regulation notices and Treasury briefings not just for what they prohibit, but increasingly for what they allow to quietly resume. In this space, permissions may speak louder than barriers.
