•    A survey of more than 1000 consumers worldwide found that willingness to bank with digital-only banks dropped to 63 per cent in the second half of last year, down from 74 per cent in the first half year, Finextra reports. Appetite for a digital-only bank as their main bank dropped from 50 per cent to 44 per cent, according to the survey by RFi. Notable drops were in the UK (where willingness to bank with a digital-only provider fell from 78 per cent to 54 per cent) and Canada (a fall from 65 per cent to 44 per cent). Respondents said they trusted traditional banks to keep their personal information private and secure. •    Despite the fall in consumer appetite for digital-only banks, Finextra also reports that app-only newcomers Starling Bank and Monzo took out the top awards at the "Best British Bank" awards. FirstDirect's three-year reign in the top spot ended, with the top five providers all coming from outside the traditional banking sector. However, NatWest succeeded in taking home the "Best Banking App" award, while HSBC M&S Bank had to settle for the wooden spoon. It's customer satisfaction score fell from 70.6 per cent in 2017 to 56.3 per cent this year.•    Amazon is in talk with US banks about developing a cheque account-style product for its millions of customers, reports the Wall Street Journal, followed up by Bloomberg. The talks with banks, including JPMorgan and Capital One, centred on developing a product targeted at "millennial consumers" could help lower the fees Amazon pays to financial firms at the same time as giving it even more information about customers' incomes and spending habits. •    The Financial Stability Board has "conservatively" estimated the value of shadow banking at more than US$45 trillion, up eight per cent, reports the FT. The FSB was able to include accurate detailed data from China and Luxembourg for the first time. It estimates that shadow banking (the parts of the financial system that "perform bank-like functions" such as lending but without the same safeguards and regulation) accounts for 13 per cent of global financial assets. The FSB report says China contributed 15.5 per cent of that conservative estimate of $45 trillion.
