Relationship Between the Dollar Index (DXY), 10-Year Bond Yield, Interest Rates, and Carry Trade
1. Dollar Index (DXY) and 10-Year Bond Yield
The DXY and the US 10-year Treasury yield generally have a direct (positive) relationship:
When the 10-year yield rises, the dollar tends to strengthen.
When yields fall, the dollar usually weakens.
This is because higher yields attract foreign capital seeking better returns, increasing demand for the US dollar and pushing up its value.
However, this relationship is not perfect and can be influenced by other factors like economic data, geopolitical risks, and monetary policy expectations.
2. Interest Rates and Their Impact
Interest rates set by central banks (e.g., Fed funds rate) influence bond yields and currency values.
Higher interest rates generally lead to higher bond yields, attracting capital inflows and strengthening the currency (USD).
Conversely, lower rates tend to weaken the currency as investors seek higher yields elsewhere.
The interest rate differential between countries is crucial: it reflects the relative attractiveness of holding one currency over another, driving capital flows and currency movements.
3. Carry Trade and Its Role
The carry trade involves borrowing in a currency with low interest rates and investing in a currency with higher yields to earn the interest rate differential.
For example, investors may borrow in Japanese yen (low rates) and invest in US dollars (higher rates), buying US bonds or assets.
This strategy increases demand for the higher-yielding currency (USD), pushing up its value and often correlating with rising bond yields in that country.
Carry trades are typically based on short-term interest rate differentials, but recent research indicates that the entire yield curve (including long-term yields) also affects currency returns and carry trade profitability.
The uncovered interest rate parity (UIP) theory suggests carry trade returns should be zero after adjusting for exchange rate changes, but empirically, carry trades have yielded excess returns, partly due to risk premia and market inefficiencies.
what is UIP???
Uncovered Interest Rate Parity (UIP) is a fundamental economic theory that relates the difference in nominal interest rates between two countries to the expected change in their currency exchange rates over the same period. It asserts that the expected depreciation or appreciation of a currency will offset the interest rate differential, eliminating the possibility of arbitrage profits from borrowing in one currency and investing in another without hedging exchange rate risk.
Key Points about UIP:
Interest Rate Differential Equals Expected Exchange Rate Change:
The difference between the interest rates of two countries should equal the expected percentage change in the exchange rate between their currencies. For example, if Country A has a higher interest rate than Country B, its currency is expected to depreciate relative to Country B’s currency by approximately the interest rate difference.
No Arbitrage Condition Without Hedging:
Unlike covered interest rate parity (which uses forward contracts to hedge exchange rate risk), UIP assumes investors do not hedge their currency exposure. Therefore, the expected spot exchange rate at the end of the investment horizon adjusts to offset potential gains from interest rate differences.
Implication:
If a country offers higher interest rates, its currency is expected to depreciate to prevent riskless profit opportunities. This reflects foreign exchange market equilibrium.
Relation to Law of One Price and Purchasing Power Parity (PPP):
UIP is connected to the law of one price, which states that identical goods should cost the same globally when prices are expressed in a common currency. Similarly, UIP ensures that returns on investments in different currencies are equalized once exchange rate changes are considered.
Practical Use:
UIP helps explain and forecast currency movements based on interest rate differentials but is often violated in the short term due to market imperfections, risk premiums, and investor behavior.
In summary, Uncovered Interest Rate Parity states that the expected change in exchange rates between two currencies offsets the interest rate differential, so investors earn the same return regardless of the currency in which they invest, assuming no hedging of currency risk.
4. Bond Prices and Interest Rates
Bond prices and interest rates have an inverse relationship:
When interest rates rise, bond prices fall.
When interest rates fall, bond prices rise.
This dynamic affects currency values indirectly, as falling bond prices (rising yields) attract capital inflows, strengthening the currency and the DXY.
Summary Table
Factor Relationship with USD / DXY Explanation
10-Year Bond Yield Positive correlation Higher yields attract foreign capital, boosting USD
Interest Rates Positive correlation Higher rates increase returns on USD assets
Interest Rate Differential Drives carry trade and currency flows Larger spread favors higher-yielding currency
Carry Trade Supports USD when borrowing low-rate currency and investing in USD Increases demand for USD and US bonds
Bond Prices Inverse to yields; indirectly affects USD Falling bond prices (rising yields) strengthen USD
Conclusion
The US Dollar Index (DXY) generally moves in tandem with the 10-year Treasury yield and interest rates because higher yields and rates attract capital inflows, strengthening the dollar. The carry trade exploits interest rate differentials, further supporting the dollar when investors borrow in low-rate currencies to invest in higher-yielding US assets. Bond prices inversely relate to yields, and their fluctuations indirectly influence the dollar through these mechanisms.
