In an industry of around 400,000 there are currently around 6,000 vacant tech jobs, according to government data.
More than half of the country's startups held an account with SVB, companies and venture capital investors said, in some cases their only U.S. banking facility although the amounts involved are not fully known.
Tech companies and investors alike said SVB was a rarity in the banking industry, familiar with Israel's tech ecosystem and offering loan terms unmatched by other banks.
Citing the judicial reforms, Adam Fisher, a partner at investment firm Bessemer Venture Partners, said fewer American banks may be willing to lend to Israeli companies, which means less competition and more onerous terms.
Israel's tech companies are therefore likely to flock to register as U.S. companies, while keeping R&D back home, said Yaron Samid, managing partner of the TechAviv Founder Partners fund.
