Be it a transaction that involves thousands of dollars or a simple login to a website, these kind of things should be kept completely secure. Heck even just viewing a website should be encrypted. This is done with SSL certificates.
As a result, Google has made it harder for unsecure websites that just use HTTP to gain popularity. Chrome now flags unsecure websites as standard which means that unless the site uses HTTPS, Chrome will notify you by displaying "Not Secure" on the URL bar when you visit the page.
