A rise in unsecured household debt added to questions over the sustainability of the economic recovery in 2016. The BoE insisted there was no cause for alarm, despite having said two years earlier that the recovery was "neither balanced nor sustainable". Following the UK's 2016 decision to leave the European Union, the BoE cut interest rates to a new historic low of 0.25% for just over a year. It also increased the amount of QE since the start of the Great Recession to £435bn. By Q4 2018 net borrowing in the UK was the highest in the OECD at 5% of GDP. Households had been in deficit for an unprecedented nine quarters in a row. Since the Great Recession, the country was no longer making a profit on its foreign investments.
