APAC FX Analysis: BNY Mellon flags inflation channels and valuation gaps

BNY Mellon’s APAC FX analysis highlights how different “inflation channels” are driving divergent monetary-policy responses across Asia-Pacific. Imported energy inflation is especially important for net-importers such as Japan and South Korea. Domestic food-price shocks are more central for economies like India and the Philippines. The report also notes core-versus-headline inflation divergence: in several countries, core inflation remains sticky even as headline inflation eases, keeping normalization timelines uneven. Service-sector inflation is described as particularly persistent in developed APAC markets. Alongside inflation, APAC FX analysis quantifies widening valuation gaps in regional currencies. Using proprietary fair-value models (incorporating terms of trade, real interest-rate differentials, and external balances), BNY argues some North Asian currencies look overvalued relative to fundamentals amid export headwinds. It also points to potential undervaluation pockets in parts of Southeast Asia where domestic cycles may improve. Real Effective Exchange Rate (REER) modeling suggests competitiveness shifts could create currency correction risk and opportunities. Policy divergence is a key catalyst. The Reserve Bank of Australia is portrayed as relatively hawkish (supportive for AUD), while the Bank of Japan remains cautious (weighing on JPY). China’s yuan management is framed as a dominant regional anchor, with managed flexibility creating both stabilizing effects and spillovers. BNY links these dynamics to real flows: overvalued currencies can hurt export competitiveness, while depreciation combined with import-led inflation can push policymakers toward a difficult stagflation mix. Valuation gaps may attract longer-term investment into undervalued regions, but currency volatility can deter short-term portfolio flows. The report references weakening historical correlations (e.g., commodity-price links to producer currencies) and advises monitoring high-frequency inflation indicators (freight rates, semiconductor prices, and PMI input prices) for FX momentum signals.
