The depreciation of the RMB, alongside a pullback of foreign funds from the region, triggered downward pressures on the region’s currencies. Since the RMB move on 11 August, Emerging Asia currencies have depreciated by an average of 3.2% against the US Dollar, with some falling by as much as 7%. 2  While markets seem to have calmed somewhat, a sense of uncertainty prevails and the risk of renewed volatility remains. What is happening? Financial markets are essentially coming to terms with four significant “re-pricings”. •  First, the stock markets in China are adjusting downwards from unsustainably high levels. •  Second, the RMB has become de-coupled from the US Dollar and is moving towards a more market-determined exchange rate. •  Third, oil and commodity prices have eased considerably this year, marking the end of what some have called a “super-cycle”. 1  Emerging Asia economies refer to China, India, Korea, Hong Kong, Taiwan, Singapore, Thailand, Malaysia, Indonesia and the Philippines. 2  Excluding the Hong Kong Dollar.

These are not necessarily unwelcome developments. The correction in China’s stock market is not surprising given the stretched valuations that had developed over the preceding year.
To a degree, the authorities have responded to this risk: last year the Financial Supervisory Authority imposed a ceiling on residential loan-to-value ratios, following analysis and discussion within the Systemic Risk Committee, which works for the Financial Stability Council, and upon receiving an opinion from the Council. Developments in the real estate market will continue to be monitored closely in this respect, and the possibility of applying additional macroprudential tools will be considered. Another risk factor that the Financial Stability Council has identified is uncertainty about future developments in the tourism sector and the potential impact that a setback in the industry would have on the position of the banking system. At the end of 2017, lending to the tourism sector accounted for 9% of the large commercial banks’ total lending, but because growth in tourism has eased recently, this ratio has held broadly steady. The Central Bank of Iceland conducts an annual stress test in consultation with the Financial Supervisory Authority, in which it examines the impact of macroeconomic scenarios on the commercial banks’ resilience. The results are published in the autumn issue of the Bank’s Financial Stability report. The last stress test assumed that there would be a recession in trading partner countries, plus a drop in major export prices and a steep decline in the number of tourists visiting Iceland. In this scenario, the banks’ capital ratios would fall by an average of 3½ percentage points, to a level close to the minimum capital ratios currently required by the Financial Supervisory Authority.
