Relationship between US Treasury bond yields and US Dollar

The relationship between currency values and US Treasury bond yields is a crucial aspect of global financial markets. Here’s how they are interconnected:

1. Interest Rate Differentials and Currency Movements

  • Higher Treasury Yields and Stronger Currency: When US Treasury bond yields rise, particularly long-term yields like the 10-year Treasury yield, it generally makes US assets more attractive to foreign investors. This is because higher yields on US bonds offer greater returns, incentivizing capital inflows into the US As foreign investors purchase more US Treasury bonds, they need to exchange their own currencies for US dollars, thereby increasing demand for the US dollar. This can lead to an appreciation of the US dollar against other currencies.
  • Lower Treasury Yields and Weaker Currency: Conversely, if US Treasury yields fall, it might make US assets less attractive because returns are lower. As a result, capital may flow out of the US, reducing demand for the US dollar, which could cause the dollar to depreciate against other currencies.

2. Expectations of Future Monetary Policy

  • US Treasury yields are closely tied to market expectations about future actions by the US Federal Reserve (Fed). If investors expect the Fed to raise interest rates (to fight inflation or curb overheating in the economy), yields on US Treasuries tend to rise. This anticipated increase in rates can attract foreign capital, driving up the demand for US dollars and leading to an appreciation of the dollar.
  • On the other hand, if the market anticipates that the Fed will lower interest rates (perhaps to stimulate the economy or deal with low inflation), yields on US Treasuries may fall. This could lead to a weaker dollar, as lower rates make US assets less attractive and result in reduced demand for the dollar.

3. Risk Sentiment and Safe-Haven Demand

  • US Treasury bonds are viewed as “safe-haven” assets, especially in times of economic uncertainty or geopolitical instability. When investors are risk-averse and seek the safety of US Treasuries, they tend to buy these bonds, which strengthens the US dollar due to the higher demand for dollar-denominated assets.
  • When US Treasury yields fall (often because of increased demand for Treasuries in uncertain times), the US dollar can initially appreciate due to its safe-haven status, despite lower yields. However, if the fall in yields is due to weaker economic prospects, the dollar may eventually weaken as investors look for better returns elsewhere.

4. Global Interest Rates and Capital Flows

  • The US Treasury bond yield acts as a global benchmark. The yield spread between US Treasuries and government bonds of other countries can influence currency values. If US yields rise relative to yields in other countries, it might cause capital to flow into the US, strengthening the US dollar.
  • Conversely, if Treasury yields remain lower than yields in other major economies (e.g., the Eurozone or Japan), it can make other countries’ bonds more attractive, leading to a shift in capital out of the US This reduces demand for the dollar, leading to its depreciation against those foreign currencies.

5. Inflation Expectations and Currency Movements

  • US Treasury yields reflect inflation expectations. If inflation is expected to rise, long-term bond yields typically increase because investors demand higher returns to compensate for the anticipated erosion of purchasing power. Higher inflation expectations may also prompt foreign investors to seek US Treasuries as a hedge, driving up demand for the dollar.
  • If inflation expectations decline, Treasury yields could fall, which may result in a weaker dollar, especially if the Fed signals lower rates in response to lower inflation.

6. Impact of Yield Curves on Currency

  • The yield curve (the difference between short-term and long-term US Treasury yields) can also influence currency markets. A steepening yield curve (where long-term yields rise faster than short-term yields) generally signals strong economic growth and rising interest rates, which can boost the value of the US dollar. A flattening or inverted yield curve (where short-term yields are similar to or higher than long-term yields) can signal economic stagnation or even a recession, which may weaken the dollar.

7. Global Factors and Currency Depreciation

  • Foreign countries often hold large quantities of US Treasuries as part of their foreign exchange reserves. Changes in US Treasury yields may lead foreign governments and central banks to adjust their currency policies. For example, if a country holds US Treasuries and the dollar strengthens (due to rising US yields), it may face currency depreciation pressure in its own economy. Some central banks may intervene by purchasing or selling their currencies to stabilize their exchange rates.

Summary of the Relationship:

  • Rising Treasury Yields → Stronger US Dollar: Higher yields make US assets more attractive, increasing demand for the US dollar.
  • Falling Treasury Yields → Weaker US Dollar: Lower yields make US assets less attractive, decreasing demand for the dollar.
  • Monetary Policy Expectations: Yields reflect expectations for US interest rate moves, which influence currency movements.
  • Risk Sentiment: Treasury yields can rise or fall due to risk appetite, affecting global capital flows and currency demand.

In essence, US Treasury yields play a significant role in determining the relative strength of the US dollar because they influence both domestic and international investor behaviour, capital flows, and economic expectations. Changes in Treasury yields can have far-reaching effects on currency markets, particularly in a globally interconnected financial system.
