The UK's "Faster Payments Scheme", used by all the major banks, has been less than fast for thousands of customers since the weekend. A system failure on Sunday has caused a backlog of thousands of payments, resulting in the transactions taking two days to process. Finextra reports the scheme is working with Mastercard-owned Vocalink, which is behind the scheme's infrastructure, to work out the cause of the initial problem.  Meanwhile, also in the UK, TSB's tech woes continue as an overnight update to its mobile app locked users out of their mobile and internet banking. It follows the bank's nightmare IT upgrade which locked up to 1.9 million customers out of their accounts in April and May.   Banks in the Eurozone are being forced to squeeze the supply of credit to home buyers as prices rise at their fastest rate since the GFC, reports the FT. House prices across the EU rose 4.5 per cent in the year to the first quarter of 2018 - and hit double digits in Latvia, Slovenia, Ireland, Portugal and Slovakia. With the European Central bank benchmark interest rate at zero (and likely to remain there for at least another year) authorities have been forced to implement macroprudential measures including price-to-income and debt-to-income caps. But there has been pushback for some central banks. The Dutch central bank wants to tighten its loan-to-value ratio further, thanks to a 9.3 per cent house price rise, but has encountered political opposition.
