Exchange rates

Sebastian Edwards, Luis Cabezas, 08 April 2021

The nominal exchange rate plays a dual role in macroeconomic adjustments – it is part of the transmission mechanism of monetary policy, and it also helps accommodate external and domestic shocks through its effect on the real exchange rate. This column uses disaggregated price index data from Iceland to test how exchange rate pass-through varies with the international tradability of goods and with the monetary policy framework. It shows that pass-through is significantly higher for tradables relative to nontradables. In addition, it finds that improvements in the credibility of the central bank are associated with declines in the exchange rate pass-through.

What would the world look like if Bitcoin completely displaced fiat currency? Jon Danielsson tells Tim Phillips that it wouldn't be a society that he would like to live in.

As the price of bitcoin continues to rise, this column argues that most of us would not want to live in a society where bitcoin succeeds. Fortunately, the internal contradictions and perverse consequences of cryptocurrencies' success mean that they are destined for failure. Until then, it might make sense for speculators to ride the cryptocurrency bubble, so long as they get out in time.

In 2015, the Swiss National Bank discontinued the minimum exchange rate of the Swiss franc relative to the euro, prompting a large and sudden appreciation of the franc. This column describes how the episode affected border prices, retail prices, and consumer expenditure. It shows how cross-sectional variation in border price changes by currency of invoicing carried over to consumer prices and allocations. This episode can help inform estimates of the sensitivity of retail prices to border prices and the sensitivity of import expenditures to relative price movements.

Recent evidence suggests flexible exchange rates do not always insulate economies from external shocks. This column provides novel evidence on how shocks that originate in the euro area spill over to its neighbour countries. In response to euro area shocks economic activity in the neighbour countries contracts as much as in the euro area – not only in countries that peg their currency to the euro, but also in those with a flexible exchange rate. It shows that a standard open economy model predicts this lack of insulation for floating exchange rates, provided the central bank targets CPI inflation.
