Dollar Weakness Signals: Global Diversification with VXUS and EEM ETFs Back in the Spotlight
As the U.S. economy slows and expectations for Fed rate cuts grow, the weakening dollar is boosting international stock ETFs like VXUS and emerging market EEM relative to domestic equities. Investors should use the rebalancing calculator to adjust the ratio between U.S. VTI and international VXUS, and optimize their globally diversified portfolios with the asset allocation calculator.

In October 2025, the Dollar Index (DXY) fell from 103 to 100, hitting its lowest level in two years. Slowing U.S. employment data and the Fed's signals of a shift toward rate cuts triggered dollar weakness, which is proving favorable for international equities and emerging market assets. VXUS (Vanguard Total International Stock ETF) is a globally diversified ETF holding approximately 8,000 stocks across developed and emerging markets excluding the U.S., allowing investors to benefit from both currency gains and price appreciation during periods of dollar weakness. Over the same period, VXUS rose 3.8% while the emerging market ETF EEM surged 5.2%, significantly outperforming U.S. stock ETF VTI at 2.1%. A weaker dollar reduces the dollar-denominated debt burden of foreign companies, boosts commodity prices that drive emerging market exports, and enhances the relative valuation appeal of non-U.S. markets, reshaping global capital flows. Investors who have traditionally run VTI-centric portfolios should now consider increasing their VXUS and EEM allocations to strengthen global diversification. By using the rebalancing calculator to adjust the VTI-to-VXUS ratio to 60:40 or 50:50 and the asset allocation calculator to monitor regional exposures, you can proactively respond to shifts in the dollar cycle.
VXUS Structure and Global Diversification Benefits
VXUS (Vanguard Total International Stock ETF) tracks the FTSE Global All Cap ex US Index, investing in stock markets worldwide excluding the United States. The fund holds approximately 8,000 securities allocated across developed markets at 65% (Europe 35%, Japan 15%, UK 10%, Canada 5%) and emerging markets at 35% (China 15%, Taiwan 8%, India 7%, South Korea 5%). With an expense ratio of just 0.08%, a dividend yield of 3.1%, and a market-cap-weighted approach favoring large caps, VXUS offers broad and cost-efficient international exposure. Key holdings include Nestlé (Switzerland, food), ASML (Netherlands, semiconductor equipment), Samsung Electronics (South Korea, electronics), TSMC (Taiwan, semiconductors), Toyota (Japan, automotive), Tencent (China, internet), and Reliance Industries (India, energy)—representative blue-chip companies from around the world. The first advantage of VXUS is its extensive diversification. A single ETF provides exposure to over 50 countries and 8,000 companies, minimizing individual country and company risk. Second, it reduces U.S. dependence. While U.S. stocks account for roughly 60% of global market capitalization, the remaining 40% is significant, and VXUS covers the non-U.S. portion. Third, it offers currency gain opportunities. During periods of dollar weakness, appreciation in foreign currencies (euro, yen, yuan, etc.) generates currency gains on top of price appreciation, maximizing returns. Fourth, there is valuation appeal. VXUS trades at a P/E of 14x compared to VTI's 21x—a 33% discount that presents compelling value. Fifth, there is dividend income. VXUS's 3.1% dividend yield is double that of VTI's 1.5%, making it attractive for income-focused investors. On the downside, the first drawback is limited growth. Over the past decade, VXUS averaged 6% annual returns versus VTI's 13%, having missed the explosive growth of U.S. Big Tech. Second, there is geopolitical risk. Exposure to politically unstable regions such as China, Russia, and the Middle East can lead to unexpected losses. Third, there is currency risk. During periods of dollar strength, currency losses can offset price gains. Fourth, there is regulatory risk. Policy changes by various governments (Chinese regulations, European carbon taxes, etc.) can affect corporate earnings. Comparing VXUS vs. VEA (developed markets only) vs. VWO (emerging markets only): VEA (Vanguard FTSE Developed Markets) covers only developed markets, offering more stability than VXUS but missing emerging market growth opportunities. VWO (Vanguard FTSE Emerging Markets) focuses solely on emerging markets, providing higher growth potential but also greater volatility. VXUS is effectively a 65% VEA + 35% VWO combination, balancing stability and growth. Therefore, international investing beginners can start with VXUS alone and later split into VEA and VWO as they gain experience. Enter a VXUS-only allocation versus a VEA+VWO combination into the asset allocation calculator and compare 10-year historical performance to see the difference between the two strategies. Generally, VXUS is superior in terms of convenience and cost.
Dollar Cycles and VTI-VXUS Allocation Adjustment Strategies
Dollar strength and weakness cycles drive the relative performance of U.S. and international stocks, making a dynamic VTI-VXUS allocation strategy highly effective. Strong dollar characteristics and response: A strong dollar typically occurs when the U.S. economy is relatively robust and the Fed is raising interest rates. The periods of 2014-2019 and 2021-2023 are prime examples. During dollar strength, U.S. companies' overseas revenues suffer currency losses, but U.S. markets themselves remain strong, pushing stock prices higher. Meanwhile, foreign companies face rising dollar-denominated debt burdens and declining commodity prices that reduce exports, weakening their earnings. VXUS experiences both currency losses and price declines, underperforming VTI. In fact, during the 2022 dollar surge, VTI fell 18% and VXUS fell 16% in local terms, but including currency losses, VXUS declined 25%. Strategy: In the early stages of dollar strength, expand VTI to 60-70% and reduce VXUS to 30-40%. Shift to a U.S.-centric portfolio to maximize the benefits of dollar strength. Enter target allocations of 65% VTI and 35% VXUS into the rebalancing calculator and adjust quarterly. Weak dollar characteristics and response: A weak dollar typically occurs when the U.S. economy is slowing and the Fed is cutting interest rates. The periods of 2001-2008, 2020, and the current environment (October 2025) are examples. During dollar weakness, U.S. companies' overseas revenues benefit from currency gains, but domestic market weakness limits price appreciation. Conversely, foreign companies see reduced dollar debt burdens and increased commodity-driven exports, improving their earnings. VXUS benefits from both currency gains and price appreciation, outperforming VTI. During the 2020 dollar weakness, VTI gained 21% and VXUS gained 11% in price terms, but including currency gains, VXUS reached 18%, narrowing the gap significantly. Strategy: In the early stages of dollar weakness, expand VXUS to 40-50% and reduce VTI to 50-60%. Shift to a globally diversified portfolio to maximize dollar weakness benefits. Enter target allocations of 55% VTI and 45% VXUS into the rebalancing calculator and adjust quarterly. Neutral dollar strategy: When the dollar trades sideways within a range (e.g., DXY 100-105), allocate 60% VTI + 40% VXUS, approximating global market-cap weights. This serves as a neutral position for long-term investors and is appropriate when the dollar's direction is uncertain. Dollar cycle indicators: First, the Dollar Index (DXY). A DXY above 105 signals strength, below 95 signals weakness, and 95-105 indicates neutrality. Second, interest rate differentials. When the U.S. 10-year yield minus the German 10-year yield exceeds +2 percentage points, it signals dollar strength; below -0.5 percentage points signals weakness. Third, economic momentum. When the U.S. ISM Manufacturing Index exceeds the global PMI average by more than 5 points, it signals dollar strength; more than 5 points below signals weakness. Fourth, Fed policy. When the Fed is raising rates, the dollar tends to strengthen; when cutting, a shift to weakness is likely. Current situation analysis (October 2025): The DXY stands at 100, entering weak territory; the U.S.-German rate differential has narrowed to +1.2 percentage points; the U.S. ISM at 48 is below the global PMI at 52; and the Fed is expected to begin rate cuts. All indicators support dollar weakness, making a strategy of expanding VXUS to 40-45% advisable. Enter a VTI 55% + VXUS 45% combination into the asset allocation calculator and simulate a dollar weakness scenario (DXY -5%, VXUS currency gain +5%) to estimate the projected one-year return.
Emerging Market EEM: Investment Opportunities and Risk Management
Dollar weakness is particularly beneficial for emerging markets, making additional allocation to EEM (iShares MSCI Emerging Markets ETF) worth considering. EEM holds approximately 800 large-cap stocks from emerging markets including China, India, Taiwan, South Korea, and Brazil, with an expense ratio of 0.70% and a dividend yield of 2.8%. Country allocation breaks down as China 30%, Taiwan 18%, India 15%, South Korea 12%, Brazil 5%, and others 20%. Key holdings include TSMC (Taiwan, semiconductors), Tencent (China, internet), Alibaba (China, e-commerce), Samsung Electronics (South Korea, electronics), Reliance Industries (India, energy), and Infosys (India, IT services). The first advantage of EEM is high growth potential. Emerging markets have GDP growth rates 2-3 times higher than developed markets (6% vs. 2%), offering significant long-term return potential. Second, there is the demographic dividend. India has a median age of 28, with consumption and production surging, while Brazil and Indonesia also benefit from young populations driving economic growth. Third, there is valuation appeal. EEM's P/E of 12x is substantially below the U.S. at 21x and developed markets at 15x, offering considerable room for multiple expansion. Fourth, dollar weakness benefits are pronounced. Emerging markets carry significant dollar-denominated debt, so when the dollar weakens, debt burdens decrease and commodity exports increase, driving substantial gains. During the 2020 dollar weakness, EEM rose 18%, approaching VTI's 21% gain. On the downside, the first risk is extreme volatility. Annual volatility of 30% is 1.7 times that of VTI (18%), with frequent sharp swings. Second, geopolitical risks are prevalent. Chinese regulatory crackdowns, India-Pakistan tensions, and Brazilian political instability create unpredictable events. Third, liquidity can be thin. Some holdings have low trading volumes, leading to significant slippage during large sell-offs. Fourth, currency risk is elevated. High volatility in the yuan, rupee, and real can cause currency losses that offset price gains. Optimal EEM allocation and rebalancing: Conservative investors should hold 0-5% in EEM. Since volatility is difficult to absorb, minimize or exclude it. VXUS already contains 35% emerging market exposure, providing sufficient indirect allocation. Balanced investors should hold 5-10% in EEM, expanding to 8-10% during dollar weakness and reducing to 3-5% during strength. VXUS at 35% + EEM at 8% equals total emerging market exposure of 43%. Aggressive investors should hold 10-15% in EEM, actively capturing emerging market growth while capping at 15% to limit risk. VXUS at 40% + EEM at 12% equals total emerging market exposure of 52%. Set a 10% EEM target with a ±3 percentage point band in the rebalancing calculator to maintain a 7-13% range. Because EEM is highly volatile, use narrow bands (±3 percentage points) to prevent runaway positions. When EEM surges above 13%, sell 3 percentage points to realize gains and reinvest in AGG or VTI. When it drops below 7%, add 3 percentage points but wait for confirmation of trend reversal before entering. China risk management: Since 30% of EEM is allocated to China, the fund is exposed to Chinese regulatory and economic slowdown risks. An alternative is allocating 5% to INDA (India-only ETF) + 5% to EWY (South Korea-only ETF) to bypass China. Another option is using 10% EMXC (Emerging Markets ex-China ETF) to completely eliminate China risk. Enter EEM 10% vs. INDA 5% + EWY 5% vs. EMXC 10% into the asset allocation calculator and simulate a China crash scenario to compare the defensive capabilities of each strategy.
Optimal Global Diversification Portfolio Combinations
Here are strategies for building globally diversified portfolios using combinations of VTI, VXUS, and EEM. Basic Global Portfolio (60/40 U.S./International): VTI 60% + VXUS 40%. This is the simplest and most effective combination, closely approximating global market-cap weights. It reduces U.S. concentration and strengthens international diversification for long-term stability. Over the past 20 years, it delivered 11% average annual returns with 16% volatility, compared to VTI alone at 13% returns and 18% volatility—slightly lower returns but significantly reduced risk. Annual rebalancing is sufficient, with adjustments triggered when allocations deviate ±5 percentage points from targets. Balanced Global Portfolio (50/50 U.S./International): VTI 50% + VXUS 40% + EEM 10%. This further reduces U.S. dependence and increases emerging market exposure to enhance growth potential. It is particularly advantageous during dollar weakness, capturing both currency gains and emerging market growth. Over the past 15 years, it delivered 10% average annual returns with 17% volatility—similar to the basic portfolio but generating excess returns during the 2020 dollar weakness period. Quarterly rebalancing manages EEM volatility. Aggressive Global Portfolio (40/60 U.S./International): VTI 40% + VXUS 40% + EEM 15% + INDA 5%. This expands international allocation to 60%, minimizing U.S. single-market risk. With 20% in emerging markets (EEM + INDA), it aggressively pursues high growth and maximizes dollar weakness benefits. Higher volatility (20%) makes this suitable for younger investors or those with strong conviction in continued dollar weakness. Quarterly rebalancing is recommended, with combined EEM and INDA allocation capped at 20%. Regionally Segmented Portfolio: VTI 50% + VEA (developed markets) 25% + VWO (emerging markets) 15% + AGG 10%. By splitting VXUS into VEA and VWO, developed and emerging market allocations can be adjusted independently. In the early stages of dollar weakness, expand VEA first to 30%, then increase VWO to 20% as weakness persists. While more complex, this approach offers flexible adjustment and is suited for advanced investors. Country-Focused Portfolio: VTI 50% + VXUS 30% + INDA (India) 7% + EWY (South Korea) 5% + EWJ (Japan) 5% + EWG (Germany) 3%. This concentrates investment in countries with strong growth expectations to pursue excess returns. India benefits from demographic dividends and digital transformation at 7% annual growth; South Korea is an export powerhouse in semiconductors and EVs; Japan is being re-rated due to yen weakness and corporate governance reforms; and Germany provides stability as Europe's manufacturing center. However, country concentration risk is significant, so limit individual countries to 7% or less. Sector Complement Strategy: Sector ETFs can be added to a global portfolio to emphasize specific themes. Example: VTI 50% + VXUS 35% + SOXX (semiconductors) 7% + ICLN (clean energy) 5% + GLD (gold) 3%. Semiconductors face strong global demand, clean energy benefits from government support worldwide, and gold serves as a hedge during dollar weakness. Rebalancing priorities: Global portfolios contain many assets, making rebalancing complex. Establish priorities accordingly. Priority 1: VTI vs. VXUS ratio (60:40 target). Priority 2: EEM allocation (10% target). Priority 3: Bond AGG allocation (20% target). Priority 4: Other assets. Check priorities 1-2 quarterly and conduct comprehensive portfolio rebalancing annually. Setting targets and bands by priority in the rebalancing calculator enables systematic management. Use the asset allocation calculator to compare historical performance and risk metrics across combinations to select the portfolio that best fits your goals and risk tolerance.
Currency Risk Hedging Strategies and Practical Guide
When investing in VXUS and EEM, currency risk is a double-edged sword. Dollar weakness delivers currency gains, but dollar strength can cut returns in half through currency losses. A deliberate currency risk management strategy is essential. Understanding currency risk: Even if VXUS rises 10% in local terms, a 5% dollar appreciation against foreign currencies reduces the actual return to 5%. Conversely, if VXUS rises 5% and the dollar weakens 5%, the return doubles to 10%. Since exchange rate movements directly impact returns, managing currency exposure is critical. Currency-hedged ETFs: HEDJ (Eurozone hedged), DXJ (Japan hedged), and DBEF (developed markets hedged) are ETFs that eliminate currency risk. For example, HEDJ holds Eurozone stocks but hedges euro exposure, reflecting only price changes. When expecting dollar strength, using HEDJ or DXJ instead of VXUS can prevent currency losses. However, hedging costs (0.5-1% annually) apply, and you forgo currency gains during dollar weakness, so the choice requires careful consideration. Partial hedging strategy: Replace half of a 40% VXUS allocation (20%) with currency-hedged ETFs while keeping the other half (20%) unhedged. Example: VTI 60% + VXUS 20% + HEDJ 10% + DXJ 10%. During dollar strength, HEDJ and DXJ provide protection; during dollar weakness, VXUS captures currency gains—covering both scenarios. Hedging adjustments by dollar cycle: During dollar strength, increase the hedged portion (VXUS 30% + HEDJ 10%). During dollar weakness, reduce or eliminate hedging (VXUS 40% + HEDJ 0%). During dollar neutrality, maintain partial hedging (VXUS 35% + HEDJ 5%). Currency gain reinvestment rules: If dollar weakness causes VXUS to generate large currency gains, pushing its allocation above target (target 40% → actual 48%), sell 8 percentage points to realize gains and reinvest in VTI or AGG. This guards against the risk of a currency reversal. Enter a currency gain scenario (VXUS +5% currency gain) into the rebalancing calculator for automatic calculation of the required adjustment amount. Currency diversification strategy: Avoid concentrating in a single currency (euro, yen) and diversify across multiple currencies. VXUS automatically diversifies across more than 50 currencies, mitigating the risk of any single currency collapse. Additionally, holding 3-5% in gold (GLD) provides a negatively correlated asset to the dollar, enhancing portfolio stability. Currency monitoring indicators: First, track the Dollar Index (DXY) on a weekly basis. When the DXY breaks above its 3-month moving average, it signals a shift to strength; a break below signals a shift to weakness. Second, monitor interest rate differentials. When U.S. rates rise faster than foreign rates, the dollar strengthens; when they fall faster, it weakens. Third, watch safe-haven demand. When geopolitical risks or recession fears spike demand for safe-haven assets, the dollar tends to strengthen. Practical currency risk management guide: Step 1 — Calculate currency exposure: Enter your current portfolio into the asset allocation calculator and check exposure by currency. Example: USD 60% (VTI), EUR 15% (within VXUS), JPY 8%, CNY 5%, others 12%. Step 2 — Assess hedging needs: When expecting dollar strength, hedge 50% of euro and yen exposure. When expecting dollar weakness, do not hedge or unwind existing hedges. Step 3 — Choose hedging tools: Use currency-hedged ETFs (HEDJ, DXJ) or futures and options. For individual investors, ETFs are the most convenient option. Step 4 — Regular review: Reassess currency trends quarterly and adjust hedge ratios. Factor in hedging costs (0.5-1% annually) and eliminate unnecessary hedges. Step 5 — Realize currency gains: When dollar weakness generates accumulated currency gains, realize a portion to lock in profits and prepare for potential currency reversal. Use the asset allocation calculator to simulate currency scenarios (dollar ±5%, ±10%) to understand in advance how currency risk affects your portfolio.
Conclusion
With clear signals of a dollar weakening trend, global diversification through VXUS and EEM is gaining renewed attention. Increase your VXUS allocation to 40-45% relative to VTI and add 5-10% in EEM to maximize the benefits of dollar weakness. Use the rebalancing calculator to execute periodic allocation adjustments and the asset allocation calculator to simulate currency risk and regional diversification effects, systematically managing your long-term global portfolio.
