A systematic FX strategy can provide stress testing for discretionary EM strategies, but it currently diverges from Morgan Stanley's bearish USD bias

Overview

This report is a Morgan Stanley Global EM Strategist thematic discussion on systematic FX strategies. It temporarily steps outside the conventional FX/EM commentary framework and focuses on how the QIS team's FX Multi-Factor Strategy can generate resilient returns across different market environments, while also discussing how discretionary macro investors can use systematic strategies as inputs in their investment process. The report emphasizes that Morgan Stanley FX and EM Strategy does not drive investment views through fixed rules, but it can use systematic signals to stress-test views, identify blind spots, improve trading conviction, and gradually incorporate more factor-based strategies into the research process.

Core views

The core views include: first, systematic FX strategies have become attractive again amid the re-emergence of carry opportunities and improved technical return patterns; second, a multi-factor framework is superior to a single carry exposure because technical, fundamental, and sentiment signals can complement one another; third, the current FX Multi-Factor strategy is modestly long USD and has a long carry bias, but the Morgan Stanley strategy team remains neutral with a bearish bias on USD, mainly because it expects the Fed policy path to be more dovish than market pricing; fourth, the team remains constructive on EM currencies and believes the optimism reflected in FX options positioning still has support; fifth, systematic signals should not mechanically replace discretionary judgment, but should serve as tools for macro PMs to test views, adjust positions, and filter market regimes.

Analysis framework

The report uses a comparative approach between discretionary macro research and quantitative strategy. The discretionary section focuses on the business cycle, monetary policy, risk appetite, valuation, positioning, and risk premia; the quantitative section cites the QIS FX Multi-Factor strategy, which scores technical, fundamental, and sentiment signals and converts them into long-short currency positions, then rebalances to a constant risk target. The report also uses net USD exposure, individual currency weights, 12-month z-scores, Sharpe ratios across macro regimes, cross-asset correlations, EM local bond flows, and FX options positioning to validate strategy signals against market views.

Methodology notes

• quantitative FX strategyFX Multi-Factor Strategy

  multi-factor FX portfolio

  This strategy does not rely on a single carry signal; instead, it combines technical, fundamental, and sentiment signals to score currencies and translate them into long-short positions, then rebalances to a constant risk target to create a more balanced FX return engine.

• position analysisnet USD positioning and currency weight z-score

  net USD exposure and 12-month weight z-score

  The report uses total exposure of -21.0% to judge that the strategy is modestly long USD relative to the portfolio currencies, and further uses the 12-month weight z-score to strip out short-term noise and identify more representative long and short currencies.

• macro scenario analysisregime analysis

  performance testing by USD direction, risk appetite, and U.S. growth regime

  The QIS strategy maintains a high Sharpe ratio across USD strengthening and weakening, risk-on and risk-off, and U.S. manufacturing expansion and contraction regimes, indicating that its returns do not fully depend on any single macro regime.

• flow and positioning monitoringEM local flow tracker and FX options positioning

  EM local bond flow tracking and FX options positioning

  The report uses foreign holdings data from nine EM local-currency government bond markets to estimate flows, and uses FX options data to observe USD and EM FX positioning in order to assess investor risk appetite and crowding.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• USD

  The systematic strategy is modestly long, but the discretionary strategy view is neutral with a bearish bias

  Strengths

  USD has performed strongly recently, and the systematic strategy has held varying degrees of long USD exposure since mid-March; FX options data also show investors remain net long USD.

  Weaknesses

  Morgan Stanley believes the Fed Funds path may come in below market and consensus expectations, and a more dovish U.S. monetary policy path supports a bearish USD view.

  Comparison

  The systematic model currently leans toward USD strength, while the strategy team's discretionary view places more emphasis on the future monetary policy path; this is the key divergence.

  Risks

  If the Fed does not turn dovish as expected, USD shorts or a bearish USD view may continue to be challenged by systematic trends and positioning signals.

• EM currency

  The strategy team remains constructive

  Strengths

  The report says it remains constructive on EM currencies and believes the optimism in FX options data is supported; flows into EM local markets have strengthened again this year.

  Weaknesses

  Overall EM FX positioning is only slightly net short and highly dispersed internally; some currencies such as TWD and INR still have large short positions, while some local markets face disturbances from oil prices, politics, and inflation.

  Comparison

  Compared with USD, the EM currency view depends more on a stable global fixed-income environment, continued carry, and controllable local policy risks.

  Risks

  Rising global interest rates, weaker risk appetite, an oil price rebound, or geopolitical shocks could pressure EM FX performance.

• CNH/CNY

  The systematic strategy is significantly short CNH, but the fundamental discussion is more cautious

  Strengths

  China's trade surplus remains strong, and exporters' FX conversion can support the renminbi; USD/CNH may move lower when USD weakens.

  Weaknesses

  Sustained CNY strength and relative outperformance versus peers could create headwinds for export-driven growth, and the systematic strategy identifies a CNH short signal.

  Comparison

  CNH is the largest short in the systematic strategy, but the discretionary analysis argues that recent trade data have not yet shown clear exchange-rate pressure.

  Risks

  If export channels come under pressure or policymakers strengthen their preference for exchange-rate stability, CNH performance may diverge from model signals.

• IDR

  One of the systematic strategy's top five longs by z-score, but regional fundamentals remain under pressure

  Strengths

  In FX options positioning, IDR is a relatively large long, and the systematic strategy also lists IDR as a preferred long.

  Weaknesses

  The report also notes that Indonesia's balance-of-payments outlook remains tilted to the downside, policy uncertainty persists, and IDR may continue to underperform relatively.

  Comparison

  Quantitative signals and some fundamental judgments are not fully aligned, making this a suitable target for discretionary PM review.

  Risks

  Oil prices, insufficient foreign inflows, policy uncertainty, and upward yield pressure could weaken IDR performance.

• ZAR

  One of the systematic strategy's top five longs by z-score; the strategy team is neutral on USD/ZAR

  Strengths

  The systematic strategy favors long ZAR; South Africa rates curve strategy prefers 1y1y–2y2y steepeners.

  Weaknesses

  The SARB faces the risk that energy shocks spread into services and expectations, and the report remains neutral on USD/ZAR.

  Comparison

  The systematic signal is positive, but the discretionary macro view focuses more on inflation and central bank policy divergence.

  Risks

  Uncertainty around energy prices, inflation expectations, and policy communication could affect ZAR and the South African curve.

• KRW

  Expected to appreciate modestly

  Strengths

  Although KRW has been one of the weaker AXJ currencies year to date, the report believes corporate FX conversion may increase and the pace of foreign equity outflows may slow.

  Weaknesses

  Outbound investment and equity-related flows may still weigh on KRW.

  Comparison

  Compared with some Asian currencies, KRW has fundamental support but is dragged by flows in the short term.

  Risks

  If foreign equity outflows continue or corporate conversion falls short of expectations, KRW upside may be limited.

• EM local currency government bonds

  Flows are improving but return performance is modest

  Strengths

  As of July 17, YTD flows are about +$20.8bn, higher than the same period in 2025; rolling 3-month inflows remain at a high historical percentile.

  Weaknesses

  Recent total returns have been broadly flat, with QTD slightly negative, as weakness in spot FX and duration offsets carry contribution.

  Comparison

  Flow indicators are correlated with local-currency government bond returns, but there is currently a mild divergence between softer returns and still-positive flows.

  Risks

  If global fixed-income conditions deteriorate or inflows slow, the risk-reward of EM local bonds may weaken.

• Morocco EUR31s vs EUR35s

  Recommended to buy EUR31s versus EUR35s

  Strengths

  The report believes outperformance in the belly of the curve has gone too far, Morocco's external buffers remain strong, and the path toward IG in 2026 remains intact.

  Weaknesses

  Higher oil prices remain the main source of pressure on the credit story.

  Comparison

  A relative-value trade is preferable to a purely directional credit exposure.

  Risks

  If oil prices rise sharply again, both the credit improvement path and the relative-value trade may be impaired.

• Total EM FX positioningabout -8, about 42nd percentileThe report says EM FX as a whole is slightly net short, but internal dispersion is large.

Impact & implications

The implication for the investment process is that discretionary macro teams do not need to treat systematic strategies as full replacements, but can use them as disciplined external signals. If a systematic strategy contradicts the discretionary view, it should trigger a review of the investment thesis; if both point in the same direction, it can strengthen confidence in entry, exit, or position adjustments. For asset allocation, the FX Multi-Factor strategy has low correlation and relatively stable cross-regime performance, which may provide a capital-efficient diversification overlay for traditional 60/40 portfolios. For the current market, the systematic strategy suggests that long USD and short CNH positions merit further study, but Morgan Stanley remains neutral with a bearish bias on USD due to its Fed path view and continues to favor EM currencies.

Risks

• The historical performance of the systematic strategy does not guarantee future returns, especially when factors become crowded or market structure changes.
• When discretionary views run opposite to systematic signals, a lack of disciplined review may amplify confirmation bias.
• If the Fed policy path is not as dovish as Morgan Stanley expects, the neutral-to-bearish USD view may come under pressure.
• The constructive view on EM currencies depends on stable global fixed-income conditions, no significant deterioration in risk appetite, and controllable local policy risks.
• An oil price rebound, El Niño-related inflation risks, political uncertainty, and changes in central bank communication could affect markets such as South Africa, Peru, Brazil, India, and Indonesia.
• FX options positioning and flow indicators may reflect lagged or localized market behavior and cannot be used alone as a trading basis.
• The report discloses that Morgan Stanley may have business relationships with covered companies, and investors should treat this research as only one factor in investment decisions.

What to watch

• Whether the gap between the Fed Funds path and market pricing widens further, as this is the key pillar of the bearish USD view.
• Whether the FX Multi-Factor strategy's net USD exposure continues to stay long USD, or shifts to align with the discretionary view.
• CNH/CNY moves, trade surplus, exporters' FX conversion ratios, and the USD/CNY fixing, to assess whether the systematic CNH short signal gains fundamental confirmation.
• Whether EM local currency government bond flows continue to build from the roughly +$20.8bn YTD level, and whether rolling 3-month inflows continue to retreat from high percentiles.
• The pace of reduction in USD long positions in FX options, as well as positioning changes within EM FX in IDR, TRY, TWD, INR, ZAR, HUF, and others.
• Policy decisions and forward guidance from EM central banks such as SARB, NBH, BCCh, BCRP, BanRep, and Banxico.
• Changes in factor leadership among global risk-on/risk-off conditions, carry effectiveness, technical trends, and fundamental signals.
