Full prediction

Within seven days, a significant BOJ rate hike and clearer exit from ultra-easy policy are likely to strengthen the yen and prompt neighboring Asian economies to reassess FX and monetary stances to preserve export competitiveness. This will directly affect South Korea, Taiwan, and ASEAN exporters whose margins are sensitive to JPY cross-rates, and could provoke localized capital flow volatility. Strategically, a firmer yen diminishes Japan’s role as a global funding currency, potentially tightening global dollar liquidity and complicating financing of large defense and energy projects across the region. Confirmation would include sustained JPY appreciation, comments from regional central banks on FX, and portfolio reallocations into yen assets; a smaller-than-expected hike or dovish BOJ guidance would curb this impact.
