Guard against a short-term squeeze in Asia FX, while remaining medium-term bullish on the dollar and bearish on Asia duration

Overview

The report focuses on Asia local rates, FX, and China asset allocation. On rates, renewed escalation in the Middle East has pushed Asian yields higher, but relative to changes in U.S. real rates and oil prices, Asian markets still appear insufficiently adjusted. Domestic growth, credit expansion, El Niño food inflation risks, central banks gradually turning hawkish, and low valuations together support underweight duration. On FX, a hawkish Fed and resilient U.S. economy continue to support the dollar, but Asian currency valuations are extremely cheap, short positioning is crowded, and a squeeze rally similar to summer 2024 may occur in the near term, making it appropriate to reduce rather than fully remove shorts. On China, although the Politburo meeting did not send a strong demand-side reflation signal, countercyclical support, exporters’ dollar conversion, and foreign investor demand remain favorable for the RMB.

Core views

Maintain the underweight in Thai government bonds within GBI-EM and continue to pay 5-year MYR and TWD rates; Asia’s low-yield markets are in the stage of forming rate-hike expectations, and the risk-reward of payer trades remains attractive. Take tactical profit on the KRW 2s10s steepener because the curve is already significantly steep relative to the fundamental model. Asia FX remains affected by a strong dollar and squeezed capital inflows, but short-term technicals support reducing the size of shorts, lowering the THB underweight from 1.0% to 0.5%. Continue to short SGD/TWD and hold INR longs versus PHP and IDR, partly hedged through INR call options. On the RMB, maintain the view of shorting USD/CNH through options, with a year-end target of 6.70.

Analysis framework

The research combines macro growth, inflation, credit, energy, and central-bank reaction functions to compare high-yield and low-yield groupings across Asian economies; it builds rates fair-value and curve regression models using U.S. real rates, Brent crude, domestic growth, inflation, and fiscal expectations; the FX section integrates two-year rate differential residuals, historical mean reversion, seasonality, investor positioning, client surveys, and policy exchange-rate frameworks to assess short- and medium-term risks.

Methodology notes

• Macro fundamentalsGrowth-inflation-policy reaction framework

  Assess the direction of rates based on growth, credit, inflation, and central-bank reaction functions

  Improving domestic growth and credit, food and energy inflation risks, and a tendency for central banks to turn hawkish jointly raise the probability of future rate hikes or rising term premia.

• Valuation modelRates fair-value regression

  Use U.S. real rates, oil prices, and domestic macro expectations to estimate fair values for Asian yields

  The report argues that the adjustment in Asia rates this month is smaller than implied by external anchors, and most low-yield markets except Korea still appear to have yields that are too low.

• Relative valueComparison of high-yield and low-yield markets

  Compare the sensitivity of Asian high-yield and low-yield economies to global rate shocks

  In this round, INR, IDR, and PHP yields have reproduced only about 40% of the March selloff, while KRW, TWD, THB, and MYR are at about 90%, creating an uncommon compression between high-yield and low-yield spreads in a rising-rate environment.

• FX valuationRate differential residuals and mean reversion

  Measure overvaluation or undervaluation of Asian currencies using two-year USD-Asia rate differential regressions

  Asia FX’s deviation relative to rate differentials has reached +1.4 standard deviations; historically, similar extreme levels have usually been accompanied by some degree of short-term mean reversion.

• Market technicalsPositioning and seasonality analysis

  Use CFTC positioning, client surveys, and U.S. data seasonality to assess squeeze risk

  Dollar longs and Asia FX shorts are relatively crowded; if U.S. data soften due to seasonality and trigger a dovish shift in Fed expectations, low-yield Asian currencies may rebound first.

• Trade managementRelative value and carry assessment

  Decide whether to hold or take profit by combining curve valuation, carry, and policy pricing

  The report continues to hold TWD and MYR payers as well as SGD relative-value trades, while locking in profits after the KRW 2s10s curve became clearly steep relative to the model.

Asset mapping & comparison

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

• Asia low-yield market rates

  Maintain payers and underweight duration

  Strengths

  Improving domestic growth and credit, central banks gradually turning hawkish, and elevated anchors from U.S. real rates and oil prices.

  Weaknesses

  Yields have risen from low levels and may fall back in the short term if geopolitical tensions cool or Fed expectations turn dovish.

  Comparison

  Compared with INR, IDR, and PHP, KRW, TWD, THB, and MYR have seen larger repricing in response to this round of global rate shocks, but valuations still look low except in Korea.

  Risks

  A rapid decline in oil prices, unexpectedly weaker growth, or central banks continuing to remain on hold for an extended period.

• Thai government bonds and THB rates

  Maintain GBI-EM underweight and hold 1y1y THB payers versus SGD

  Strengths

  Growth is stronger than expected, core inflation is no longer declining, the current account is deteriorating, and there is limited room for oil-price subsidies.

  Weaknesses

  The BOT’s baseline scenario is still to keep rates at 1.00% from 2026 to 2027, with a relatively dovish policy stance.

  Comparison

  Thailand’s policy pricing is more moderate than Korea’s; if the economy continues to exceed expectations, there is more room for repricing.

  Risks

  A fall in global energy prices, a loss of momentum in Thai growth, or the BOT maintaining an accommodative stance.

• 5-year TWD IRS

  Maintain payer

  Strengths

  A strong AI technology cycle, industrial production, manufacturing sentiment, and producer prices support higher rates.

  Weaknesses

  Inflation is not yet threatening, and the CBC still focuses on weak parts of the economic structure.

  Comparison

  Among Asia’s low-yield currencies, TWD rates and FX have the strongest negative correlation with the dollar.

  Risks

  Cooling in the technology cycle, a decline in core inflation, or the CBC continuing to tolerate loose financial conditions.

• 5-year MYR NDIRS

  Maintain payer

  Strengths

  Second-quarter GDP grew 5.8% year-on-year, growth is broad-based, and the market has not yet priced one full rate hike over the next two years.

  Weaknesses

  BNM has not yet clearly signaled policy normalization, and inflation data have repeatedly come in below expectations.

  Comparison

  Compared with Korea, where tightening is fully priced, Malaysia’s curve underprices potential rate hikes.

  Risks

  No hawkish shift in September or failure of fourth-quarter rate-hike expectations to materialize.

• KRW 2s10s curve

  Take profit on steepener trade

  Strengths

  Previously supported by front-end facts being realized, a reassessment of long-end growth potential, and changes in issuance structure.

  Weaknesses

  The curve is already significantly steep relative to models based on the USD curve, policy rate differentials, and fiscal expectations.

  Comparison

  Korean rates are already among the cheaper markets in Asia’s low-yield universe, reducing the risk-reward of further steepening.

  Risks

  Further AI investment may lift potential growth and the natural rate, continuing to push the long end higher.

• Asia FX

  Maintain underweight but tactically reduce shorts

  Strengths

  Near-term valuations are extremely cheap, positioning is crowded, and U.S. data face seasonal softening risks.

  Weaknesses

  A hawkish Fed, resilient U.S. economy, and strong dollar continue to crowd out capital flows into Asia.

  Comparison

  The near-term environment resembles the carry-trade unwind of August to September 2024, but current U.S. employment and the rate cycle provide stronger support for a medium-term dollar rally.

  Risks

  The Fed turns even more hawkish, energy supply shocks occur, or U.S. data remain strong.

• THB

  Reduce underweight from 1.0% to 0.5%

  Strengths

  Popular short positioning may trigger rapid short covering when risk appetite improves.

  Weaknesses

  The policy mix still favors loose monetary policy, expansionary fiscal policy, and a weaker exchange rate.

  Comparison

  Compared with currencies with lighter positioning, THB may have greater elasticity in a squeeze rally.

  Risks

  Rising energy prices, current-account deterioration, and active policy guidance toward currency weakness.

• SGD/TWD

  Maintain short

  Strengths

  Both MAS and CBC have policy incentives to stabilize nominal effective exchange rates, and TWD is already near the weak end of the policy band.

  Weaknesses

  Ample Singapore deposits and moderate domestic price pressures continue to suppress SGD rates.

  Comparison

  The report also prefers receiving SGD rates and paying MYR and THB rates.

  Risks

  MAS tightens more than expected or TWD appreciates significantly due to technology-related capital flows.

• INR versus PHP and IDR

  Maintain INR longs, partly hedged with INR call options

  Strengths

  Relative value and option structures can control overall downside risk in regional FX.

  Weaknesses

  Asian currencies overall still face pressure from a strong dollar and tighter financial conditions.

  Comparison

  INR, PHP, and IDR all belong to high-yield markets with relatively limited yield repricing in this round.

  Risks

  Deterioration in India’s external balance or further improvement in PHP and IDR policy credibility.

• CNH

  Maintain longs through options and short USD/CNH

  Strengths

  Countercyclical policy, foreign demand for Chinese assets, exporters’ dollar conversion, and a gradual lowering of the fixing jointly support the RMB.

  Weaknesses

  China’s PMI is weak, and the Politburo meeting has not yet signaled a decisive demand-side reflation shift.

  Comparison

  Compared with other Asian currencies, the RMB is already relatively cheap and lacks the starting conditions similar to the 2015 depreciation cycle.

  Risks

  Further weakening in China’s growth, policy stimulus falling short of expectations, or a renewed rapid strengthening of the dollar.

Key data

• Yield repricing in high-yield marketsAbout 40%INR, IDR, and PHP yield moves in this round are about 40% of the March selloff.
• Yield repricing in low-yield marketsAbout 90%KRW, TWD, THB, and MYR yield moves in this round are about 90% of the March selloff.
• El Niño inflation impactAbout +0.3 percentage points on averageJPMorgan Economics estimates that a super El Niño could raise overall Asian inflation by an average of 0.3 percentage points.
• Korea policy rate terminal forecast3.75%JPMorgan’s base case expects the terminal rate to be reached by the end of 2Q27 and believes consecutive rate hikes may occur in August 2026.
• Malaysia second-quarter real GDP+5.8% year-on-yearAbove the 5.2% market consensus and JPMorgan’s 5.4% forecast, with a quarter-on-quarter annualized rate of 8.5%.
• Asia FX deviation versus rate differentials+1.4 standard deviationsBased on valuations of Asian currencies relative to two-year rate differentials, indicating relatively high short-term mean-reversion risk.
• Asia FX client positioning score-0.98Exactly the same as in July 2024, reflecting crowded underweights in Asia FX.
• THB underweight adjustmentReduced from 1.0% to 0.5%The underweight size within GBI-EM is halved to manage short-term short-squeeze risk.
• KRW 2s10s steepener tradeEntry 0.26%, exit 0.38%, P&L 24bpCarry was 0.12%; profit was taken because the curve had become clearly steep relative to the fundamental model.
• TWD nominal effective exchange rate position-3.6%Within the ±5% policy band, potentially strengthening the CBC’s hawkish bias.
• USD/CNH year-end target6.70Maintain RMB longs through options, i.e., short USD/CNH.

Impact & implications

From an allocation perspective, investors should distinguish between short-term technical rebounds and medium-term fundamental trends: Asia rates remain suitable for underweight duration, especially in low-yield markets with strong growth and insufficient policy pricing; Asia FX shorts should not be further expanded when valuations are extreme and positioning is crowded, but if the short-term rebound continues, dollar longs can be rebuilt. The RMB has better policy and flow support than other Asian currencies. If energy supply shocks escalate again, they will reinforce downside risks to Asia FX by tightening financial conditions and push up rates and term premia.

Risks

• The Fed’s stance is more hawkish than market pricing, and U.S. front-end rates and dollar risk premia continue to rise.
• The Strait of Hormuz or Bab el-Mandeb is disrupted again, triggering crude oil and natural gas supply shocks.
• A super El Niño pushes up food inflation, forcing Asian central banks to tighten policy faster.
• Asia FX short positioning is crowded; if U.S. data weaken or Fed expectations turn dovish, violent short covering may occur.
• Asian growth and the technology export cycle unexpectedly cool, weakening the basis for rates payer trades.
• China’s countercyclical support is insufficient, PMI remains weak, and sentiment toward RMB assets is depressed.
• Rebuilding European winter natural gas inventories intensifies tensions in global energy markets and tightens Asian financial conditions.

What to watch

• U.S. core CPI, nonfarm payrolls, and their seasonal revisions, and their impact on Fed rate-hike expectations.
• Fed officials’ comments and market pricing of the December 2026 policy action.
• Whether the BOK hikes consecutively in August and whether the terminal rate moves toward 3.75%.
• Whether BNM turns hawkish in September and paves the way for a fourth-quarter rate hike.
• The number of dissenting votes at the CBC meeting, core inflation, and the position of the TWD nominal effective exchange rate.
• BOT’s response to above-potential growth, core inflation, and current-account deterioration.
• Asia FX positioning, JPMorgan client surveys, and the pace of short covering in popular shorts such as THB.
• China PMI, PBoC easing, Politburo countercyclical policies, and exporters’ FX conversion flows.
• Whether USD/CNH can continue to decline and approach the year-end target of 6.70.
• Changes in the Strait of Hormuz, Bab el-Mandeb, and European natural gas inventories.
