What this means for the bank

The checker's own notes on each record:

MX, fail: No MX records, so crbt.bank cannot receive mail. Every reply to a cold email sent from it bounces.
SPF, fail: No SPF record on crbt.bank. Receivers have no list of the servers allowed to send as you, so they cannot tell your mail from a forgery.
DMARC, pass: Policy p=reject: receivers are asked to refuse mail that fails.
DMARC, info: Reports go to dmarc_rua@encirca.com.
DKIM, info: No DKIM key at the 10 common selectors tried. That does not mean DKIM is missing. Your email provider picks the selector name, and DNS has no way to list them.

What this means if you sell to Cedar Rapids Bank and Trust Company

crbt.bank publishes no MX records, so it does not receive mail. Cedar Rapids Bank and Trust Company's staff mail must run on another domain, which this check did not read. Before you send, run your own domain through the email setup checker and publish a policy with the DMARC record generator. For how a bank buys, see the selling to banks playbook.
