The Dollar's Smile: Understanding Currency Movements and Investment Strategies

Uncover how the dollar smile theory impacts your investments, from managing offshore exposure to optimizing the RISE EasyRetire portfolio. Deresh Lawangee, CEO at EasyRetire RISE, breaks down these insights.

Why Does It Occur?
The dollar smile happens because of how the US economy and global markets interact. There are three key situations:

1. Global Economic Weakness: When the world economy is in trouble, investors see the US dollar as a safe place to put their money. This makes the dollar more valuable. Even if the US economy isn't particularly strong, the dollar still goes up because it's seen as stable and safe.
2. Moderate US Growth and Global Stability: When the US economy is growing steadily and the world economy is stable, investors feel more confident taking risks and investing in other countries. This reduces demand for the dollar, making it weaker.
3. Strong US Economic Performance: When the US economy is very strong, with high growth and rising interest rates, investors want to invest in the US for better returns. This increases the demand for the dollar, making it stronger.

Tying Back to American Exceptionalism
The dollar smile connects to the idea of American exceptionalism, which means the US is seen as unique in the world because of its strong economy and stable government. This belief helps make the US dollar the world's main reserve currency. Investors everywhere trust the dollar, especially during uncertain times. This trust is a key reason for the dollar smile, showing why the dollar attracts investment in different economic conditions.

From Bretton Woods to Dollarization of Trade
In 1944, the Bretton Woods Agreement made the US dollar the main global currency, replacing gold. This agreement helped stabilize exchange rates and made international trade easier. When the US stopped using the gold standard in 1971, the dollar's role grew even more. Today, many countries use the dollar for trade and as a reserve currency, a process called dollarization.

Due to these unique set of circumstances, the US is one of the only countries that can print more money and incur more debt without the repercussions of weakening its currency.

Future Challenges to Dollar Hegemony
While the dollar smile theory currently holds, future challenges to dollar hegemony are emerging. Interest in alternative currencies, such as cryptocurrencies and the proposed BRICS currency for commodity trade, is growing. This shift is becoming more important as the US increasingly uses the dollar as a political tool, implementing sanctions and other measures—a process often referred to as the weaponization of the dollar. Such actions may drive other countries to seek alternatives to the US dollar, potentially altering the dynamics of global currency markets.

Implications for South African Investors: Managing the RISE EasyRetire Portfolio
For South African investors, especially the team involved in managing the RISE EasyRetire portfolio, understanding the dollar smile is crucial for making informed investment decisions that enhance portfolio performance. Here’s how this understanding can be applied:

1. Strategic Offshore Exposure: By recognizing the phases of the dollar smile, portfolio managers can strategically adjust the level of offshore exposure. During periods of global economic weakness, the US dollar tends to strengthen. In such times, increasing exposure to US dollar-denominated assets can provide higher returns due to the appreciating dollar. Conversely, during periods of strong US economic performance, the portfolio can benefit from both the appreciating dollar and the robust performance of US assets.
2. Hedging Strategies: Understanding the dollar smile allows for effective hedging strategies. When the dollar is expected to weaken (moderate US growth and global stability), hedging against dollar depreciation can protect the portfolio’s value. This can be achieved through currency hedging instruments that mitigate the risk of a declining dollar.
3. Diversification: Knowledge of the dollar smile encourages diversification. During different phases of the dollar smile, diversifying investments across various currencies and regions can reduce risk and enhance returns. For instance, when the dollar is strong, diversifying into emerging markets can capture higher growth potential, while maintaining some exposure to the strong dollar.
4. Timing of Investments: The timing of investments can be optimized by understanding the dollar smile. For example, entering the US market when the dollar is expected to appreciate can maximize returns. Conversely, reducing exposure or taking profits when the dollar is likely to weaken can preserve gains.
5. Crisis Positioning: Dollar positioning is particularly important during a geopolitical event or economic crisis, such as the 2008 Great Financial Crisis. During such times, investors flock to the dollar. In an economic crisis, there is an embedded assumption that the US will take necessary actions to stabilize the economy, effectively making the Federal Reserve the central bank for the entire world. This makes the dollar a crucial asset in crisis management.
