US bill targets ASML's China chip sales

3 min read

A US Congressional bill, the MATCH Act, would let Washington bar ASML from selling or servicing its DUV machines in China; the Dutch Cabinet, in Washington on 24 June, called itself 'irritated'.

Key takeaway

A US bill would let Washington govern ASML's China sales, overriding the Netherlands' own export licences.

A bill moving through the US Congress, the MATCH Act, would extend American export controls to allied chipmakers, letting Washington decide what firms in partner countries may sell to China, and ASML is the target. The proposed law would stop the Dutch firm selling, or even servicing, its deep ultraviolet (DUV) immersion lithography machines for Chinese customers. ASML is the world's only supplier of the most advanced chipmaking tools, and the Netherlands, not Washington, writes its export licences.

The Dutch Cabinet was in Washington for consultations when the bill surfaced on 24 June, and came away, in the word officials used afterwards, "irritated". ASML shares fell roughly 7% from their June high before recovering part of the drop. Washington also pressed an unconfirmed allegation that an ASML extreme ultraviolet (EUV) machine, the irreplaceable tool no chip below 7nm can be built without, had reached China without authorisation. ASML denied it, and the Netherlands has banned EUV exports to China since 2019.

ASML had already watched its Chinese business shrink under the existing DUV controls, its 2026 guidance landing €300m below analyst consensus . The MATCH Act tightens the screw a different way: it would let Washington override The Hague's own licensing and set Dutch trade policy by US statute. That runs against Pax Silica, the chip-coordination alliance the two governments had just deepened, in which the Netherlands had signed on as a partner rather than a subordinate.

Deep Analysis

In plain English

ASML is a Dutch company that makes the machines used to print computer chips. Without ASML's equipment, nobody can build the most advanced chips in the world. The US has already banned ASML from selling its most cutting-edge machines to China. Now a new American bill, the MATCH Act, would also ban ASML from selling or even repairing its older, less advanced machines for Chinese customers. The Netherlands has its own rules about what ASML can sell and to whom. The MATCH Act would override those Dutch rules with American ones, meaning the US Congress would effectively decide Dutch trade policy for one of Europe's most important companies. The Dutch government was in Washington for meetings when the bill came up, and officials said they were annoyed by it.

Deep Analysis
Root Causes

ASML holds a structural monopoly on extreme ultraviolet lithography machines and an effective duopoly, alongside ASML itself at older nodes, on deep ultraviolet immersion scanners. No Chinese, Japanese or US manufacturer has demonstrated a credible path to replicating either technology within a decade.

That concentration gives the US a single chokepoint through which to regulate global semiconductor advancement, and the MATCH Act is designed to extend US authority over that chokepoint from EUV (already controlled) to DUV (currently sold under Dutch licences).

ASML's Q1 2026 results showed China's share of its system sales falling from 36% to 19% in a single quarter under existing controls, a decline of roughly €1.8bn. The MATCH Act would eliminate the remaining 19%, which is almost entirely DUV servicing of machines already installed in China. The commercial impact on ASML would be marginal relative to that already absorbed; the political impact on the Dutch government's independent trade policy would be structural.

What could happen next?
  • Risk

    If the MATCH Act passes and the Netherlands complies, it establishes that US Congress can override sovereign European export-licensing decisions for strategically important companies without treaty obligation.

    Medium term · Reported
  • Consequence

    ASML's remaining Chinese DUV servicing revenue, roughly 19% of system sales, would be eliminated, though this continues a decline already underway rather than representing a new hit.

    Short term · Assessed
  • Risk

    The EUV-transfer allegation, if substantiated, could trigger Dutch domestic criminal proceedings and damage ASML's relationship with the Dutch government, which currently defends the company's position.

Causes and effects
This Event
US bill targets ASML's China chip sales
US legislation overriding Dutch export control would put an ally's chip-tool trade under Washington's discretion, contradicting the Pax Silica partnership both had just deepened.
Different Perspectives
Shipping and insurance underwriters
Shipping and insurance underwriters
Kpler counted five Hormuz transits on 16 August against 31 the previous weekend, while Windward logged four vessels going AIS-dark for up to a month; underwriters price both the attacks and a sanctions register that names their counterparties in unreadable scanned images. Two trackers now measure only the ships that consent to be seen.
China
China
China sits at the end of the payment chain the 14 August designation targets: Iran's shadow banking network exists to convert sanctioned oil sales, much of it to Chinese refiners, into usable funds. Beijing has previously refused to recognise OFAC's jurisdiction over its own entities buying Iranian crude, leaving this designation to test compliance rather than change trade.
Qatar
Qatar
Qatar's foreign ministry denied on 16 August holding any Iranian pilots alive, contradicting Iranian General Mohammad Bagherzadeh's claim that Doha holds three Su-24 aircrew, and said it had recovered only one set of remains. Qatar carries Iran's messages to Washington, and this is a public break with Tehran over a fact only one aircrew inquiry can settle.
Oman
Oman
Oman's shipping-map talks, covering monitoring, environment and maritime services, were publicly decoupled from any Hormuz reopening by Iran's own foreign minister on 17 August. Muscat's mediation channel keeps functioning on the narrow file it was given, while the political decision it hoped to unlock stays with Iran's security council.
Saudi Arabia
Saudi Arabia
Saudi Arabia separately called the recurrence of tanker attacks on Emirati shipping a dangerous escalation, breaking from the UAE's repeated formula. Riyadh speaking in its own name over an attack on another state's vessels signals it reads the pattern differently from Abu Dhabi's flat statements.
United Arab Emirates
United Arab Emirates
The UAE foreign ministry condemned a third ADNOC-linked tanker attack on 15 August in language identical, word for word, to its statement the day before. Three consecutive strikes on Emirati shipping have not moved Abu Dhabi's public wording by a single adjective.
