Currency Manipulation: How Countries Influence Exchange Rates
This paper examines the various mechanisms by which governments influence or control their currency's exchange rate. It discusses monetary policy tools such as low interest rates, as illustrated by Japan's deliberate suppression of the yen to stimulate its export-driven economy. The paper also covers open market transactions, using China's management of the yuan as a central example, including trading bands and official exchange rate-setting. Additional topics include currency pegging to major global currencies, the existence of multiple official and black-market rates as seen in Venezuela, capital controls, and the risks of currency crises when governments can no longer sustain an artificial rate. The paper concludes that while governments have many tools at their disposal, market forces ultimately prevail.

What makes this paper effective
- Uses concrete country-specific examples — Japan, China, and Venezuela — to ground abstract economic concepts in observable policy decisions, making arguments easy to follow.
- Moves logically from indirect market-based tools (interest rates) to increasingly direct interventions (official pegs, capital controls), giving the paper a clear analytical progression.
- Draws on a mix of academic sources (Kim & Ying, Staiger & Sykes) and journalistic sources (Slate, The Economist) to balance theoretical grounding with real-world currency.
Key academic technique demonstrated
The paper demonstrates comparative policy analysis: rather than examining one country in depth, it surveys multiple national approaches to a single economic problem, allowing readers to see how different objectives — export promotion, debt management, economic stimulus — drive different policy choices. This breadth-over-depth approach suits a short explanatory essay and is well-executed here.
Structure breakdown
The essay opens with a brief framing of why countries manipulate currencies, then dedicates a paragraph each to monetary policy (Japan), open market intervention (China), official pegging and multi-rate systems (Venezuela), and finally currency crises and capital controls. A short conclusion synthesizes the key takeaway. Each paragraph functions as a self-contained case, linked by a consistent analytical thread about government vs. market power over exchange rates.
Introduction to Currency Manipulation
A country can interfere in foreign exchange markets for a variety of reasons. In many cases, the motivation lies with propping up exporters by lowering the value of the domestic currency. While this is the most common reason for currency manipulation, it is not the only one. In some cases, currency manipulation aids in making debt disappear by lowering the value of that debt so that it might be repaid early. This paper examines some of the different ways that countries can affect their exchange rates.
Monetary Policy and Interest Rates
A freely-traded currency should reflect the economic strength of a nation — in particular, expectations for future interest rates. Where expectations for future rates are relatively low, the economy is expected to perform worse. This is the case for Japan. The country has recently adopted a policy of a low yen in order to provide some spark to its export-driven economy. When currency is affected in this way, it is usually the result of monetary policy and is carried out openly.
Monetary policy to enact foreign exchange rate policy can take a couple of different forms. The first is that interest rates are kept low. Rates in Japan are low, for example, which is pushing down the yen. This also reflects, however, sluggishness in the Japanese economy, which in turn is a function of an aging, stable population and flatlining per capita consumption. There is little doubt that Japan wants to keep its rates low to suppress the yen, but this is probably still reflective of the yen's intrinsic value, given that it trades freely and the economy really is going nowhere fast (Wernie, 2014). Just a statement from the government alone was enough to move the markets.
Open Market Transactions and the Chinese Yuan
Another form of monetary policy involves open market transactions. China is famous for using open market transactions to suppress the value of the yuan, a practice frequently criticized for artificially lowering the value of its currency for the benefit of its exporters (Staiger & Sykes, 2008). But there are other means by which a country can affect the exchange rate of its currency. China employs another method as well — it allows the yuan to trade only within a given band. The open market supports this, but ultimately the Chinese government sets the official exchange rate for the currency (Palmer, 2012).
