Hatch is a Kiwi Wealth brand (www.kiwiwealth.co.nz) and does not hold your shares. Hatch provides access to the US share markets via our partner DriveWealth, US regulated broker-dealer.
ICBC FS custodies your shares. ICBC FS (http://www.icbcfs.com/about/) is headquartered in New York City and is a wholly owned subsidiary of ICBC Bank, which is one of the largest banks in the world.
In the case of US broker insolvency, Securities Investor Protection Corporation (SIPC) protects against the loss of cash and shares held by a customer at a financially-troubled SIPC-member brokerage firm. The limit of SIPC protection is $500,000 USD, which includes a $250,000 USD limit for cash.
Please note, when money is held in your Hatch account (uninvested), it is swept into a money market fund that is not protected under SIPC. You can find the money market fund prospectus here.
The money you invest through Hatch is not insured against losses on the share markets.
