The impact of the Trump administration’sto chokereverberated across the global supply chain on Monday,some of the biggest component-makers.

Chipmakers including Intel Corp.,,andhave told their employees they will not supply Huawei till further notice, according to people familiar with their actions. Alphabet Inc.’s Google cut off the supply of hardware and some software services to the Chinese giant, another person familiar said, asking not to be identified discussing private matters.

The Trump administration on Friday blacklisted Huawei -- which it accuses of aiding Beijing in espionage -- and threatened to cut it off from the U.S. software and semiconductors it needs to make its products. The ban, which had been anticipated, hamstring the world’s largest provider of networking gear and No. 2 smartphone vendor.

The impact of the ban also began to be felt outside the U.S. and Asia. Germany’sfell in early trading Monday after the Nikkeiit halted shipments to the Chinese company in the wake of the U.S. ban. Shares of STMicroelectronics NV and Austrian-based AMS AG were also hit.

An Infineon spokesman said that the majority of products it delivers to Huawei are not subject to U.S. restrictions, adding that the chipmaker can "make adaptions in our international supply chain." AMS also said that it had not suspended shipments to Huawei.

Huawei said it will continue to provide security updates and sales services to customers using Google’s Android operating system, according to a company statement Monday.

Blocking the sale to Huawei of critical components could also disrupt the businesses of American chip giants likeand retard the rollout of critical 5G wireless networks worldwide -- including in China. That in turn could hurt U.S. companies that are increasingly reliant on the world’s second largest economy for growth.

If fully implemented, the Trump administration action could have ripple effects across the global semiconductor industry. Intel is the main supplier of server chips to the Chinese company, Qualcomm provides it with processors and modems for many of its smartphones, Xilinx sells programmable chips used in networking and Broadcom is a supplier of switching chips, another key component in some types of networking machinery. Representatives for the chipmakers declined to comment.

Huawei “is heavily dependent on U.S. semiconductor products and would be seriously crippled without supply of key U.S. components,” said Ryan Koontz, an analyst with Rosenblatt Securities Inc. The U.S. ban “may cause China to delay its 5G network build until the ban is lifted, having an impact on many global component suppliers.”

Huawei’s $500 million bond due 2027 was indicated 0.3 cents on the dollar lower at 93.8 cents at 2 p.m. in Hong Kong, according to Bloomberg-compiled prices. That’s after it posted a record drop of 2.4 cents on Friday. The ban’s commencement alsoshares of Asian tech supply chain companies Monday.was again the worst performer on Hong Kong’s Hang Seng Index, whiledived as much as 9.8% in Shenzhen.

To be sure, Huawei isto have stockpiled enough chips and other vital components to keep its business running for at least three months. It’s been preparing for such an eventuality since at least the middle of 2018, hoarding components while designing its own chips, people familiar with the matter said. But its executives believe their company has become a bargaining chip in ongoing U.S.-Chinese trade negotiations, and that they will be able to resume buying from American suppliers if a trade deal is reached, they said.

The American companies’ moves are likely to escalate tensions between Washington and Beijing, elevating fears that President Donald Trump’s goal is to contain China, triggering a protracted cold war between the world’s biggest economies. In addition to a trade fight that has rattled global markets for months, the U.S. has pressured both allies and foes to avoid using Huawei for 5G networks that will form the backbone of the modern economy.

“The extreme scenario of Huawei’s telecom network unit failing would set China back many years and might even be viewed as an act of war by China,” Koontz wrote. “Such a failure would have massive global telecom market implications.”

U.S. spy chiefs have in past days briefed American companies, investors and other important groups on the dangers of doing business with China, the Financial Times reported Monday.

The American clampdown also deals a direct blow to Huawei’s fast-growing mobile devices division. Huawei will only be able to access the public version of’s Android mobile operating system, the world’s most popular smartphone software. It won’t be able to offer proprietary apps and services from Maps and search to Gmail, said the person, who requested anonymity speaking about a private matter. That will severely curtail the sale of Huawei smartphones abroad, though it’s unclear when those apps -- which are popular mainly outside of China -- will become unavailable.

Huawei, the world’s largest smartphone brand after, was one of a select few global hardware partners to receive early access to the latest Android software and features from Google. Outside of China, those ties are critical for the search giant to spread its consumer apps and bolster its mobile ads business.

The Chinese company will still have access to app and security updates that come with the open-source version of Android. Reuters reported the move earlier. “We are complying with the order and reviewing the implications,” a Google representative, without elaborating.
