In The Yen\u2019s Depreciation<\/a>, we examined why the yen has depreciated against other currencies. We looked at the USD\/JPY exchange rate over the past few years and found that the yen has been losing value against the US dollar since April 2013, when Japan launched quantitative easing (QE).<\/p>\n \u00a0In short, we pointed out that the depreciation of the yen was due to an increase in the monetary supply in Japan. This increased supply made it less profitable to hold the currency, and as a result, market participants increased their short positions on the yen against a backdrop of increasing dollar strength.<\/p>\n \u00a0Many believe that currency depreciation will stimulate exports because a cheaper yen will supposedly provide Japanese goods with a competitive advantage. We have several observations related to this widespread belief.<\/p>\n \u00a0First of all, the depreciation of a country\u2019s currency has a deglobalizing effect for any economy. In a modern economy where there\u2019s a wide and extensive division of labor, all countries depend on other countries, either to acquire finished goods or to acquire the raw materials needed to produce finished goods for domestic consumption or exports. A \u201ccheap\u201d currency will increase the price of imported raw materials, which in turn generates additional costs for local producers.<\/p>\n \u00a0On the other hand, empirical evidence does not suggest that the exchange rate is a determining factor for the success of a country\u2019s exports. Rather, the challenge for businesses is to offer goods and services demanded by consumers at attractive prices. Just consider how eurozone exports grew from 2011 to the first quarter of 2014, a period in which the euro appreciated significantly against the dollar.[1]<\/a><\/p>\n \u00a0Remember that between 2011 and 2014, the United States was in the process of executing QE programs which weakened the dollar against the euro and other important currencies. The same is true for Japan, as seen in the graphs below.<\/p>\n \u00a0 Except for a period between the end of 2008 and 2009, when the global economic crisis was felt in Japan, exports remained at relatively strong levels between 2011 and 2014. If we look at the exchange rate during this period, we find that those export levels were posted in an environment in which the yen was \u201cexpensive\u201d against the dollar compared to the current exchange rate.<\/p>\n \u00a0 The increased pace of exports between 2005 and 2007 may be attributed to the economic boom prior to the crisis of 2008 and not to the yen exchange rate, which was at levels similar to the current one. Instead, Japan clearly experienced growth in exports in a post-crisis context with a \u201cstrong\u201d yen and a global economy much less heated than in years prior to the crisis. So it seems that Abenomics<\/em><\/a> is not an effective way to reactivate Japanese exports. We believe there are various other elements of the Japanese economy that must be examined, especially public debt levels. Japan has one of the highest debt-to-GDP ratios, and the IMF has already issued warnings and recommendations regarding the country\u2019s \u201cunsustainable\u201d debt levels<\/a><\/p>\n![\"Japan](\"https:\/\/trends.ufm.edu\/en\/wp-content\/uploads\/2015\/08\/Japan-exports-27072015.png\")
