What happened
Global stock markets faced renewed selling after the US Federal Reserve held its benchmark interest rate at 5.25 percent to 5.50 percent in September 2023. The Federal Open Market Committee - the Fed panel that sets borrowing costs - signaled that rates would stay elevated for longer.
This policy stance led to capital shifts across major trade-dependent economies in Asia. Overseas funds sold regional shares to secure higher risk-free yields in US dollar bonds. South Korea and Taiwan felt this pressure directly because foreign capital owns a significant share of their stock markets.
Foreign institutional investors sold $1.8 billion of South Korean shares in September 2023. During the same month, net foreign outflows from Taiwan reached $4.2 billion. The Korean won fell by 1.8 percent against the dollar in September 2023. The New Taiwan dollar declined by 1.3 percent over the same period. Higher US yields continued to pull capital back toward North American debt securities.
Why the kospi index taiwan asian reaction matters
Stock exchanges in East Asia act as early indicators for global capital movements. When US borrowing costs rise, capital shifts away from emerging equities. This tightening cycle affects supply chains and corporate earnings across technology hubs.
For an Indian investor, these foreign capital shifts carry direct implications. Overseas funds view emerging markets through regional allocation buckets. When institutional investors cut exposure to Asian semiconductor exporters, they often adjust their entire emerging market portfolio. That broader adjustment can trigger foreign institutional selling in Indian equities as well.
In 2023, semiconductor products accounted for nearly 20 percent of South Korea total exports and over 35 percent of Taiwan total exports. Because these markets depend heavily on global technology demand, their earnings fluctuate with global economic growth. Tracking these export-heavy indices provides Indian investors with early signals about global risk appetite and foreign capital allocation patterns.
The numbers
Capital flows during the 2023 monetary tightening cycle highlight the scale of foreign institutional movement. South Korea recorded total foreign net equity selling of $2.1 billion across the third quarter of 2023, from July 2023 through September 2023. Taiwan saw net foreign institutional equity outflows of $10.5 billion over the same three-month period.
Market valuation metrics reflected these fund movements. The KOSPI index in Seoul dropped 3.9 percent during September 2023. The Taiex index in Taipei fell 3.2 percent over the same thirty-day window.
Currency markets experienced matching pressure. The South Korean won traded at 1,349 won per US dollar at the end of September 2023, down from 1,318 won per dollar at the end of August 2023. The New Taiwan dollar moved from 31.85 to 32.27 per US dollar in September 2023. Foreign investors faced both equity price declines and currency conversion losses during this month.
What it means for investors
Investors should distinguish between different types of emerging markets. South Korea and Taiwan rely heavily on manufacturing exports, chip supply chains, and global trade volume. India relies far more on domestic consumption, private capital expenditure, and local service sectors.
When global monetary conditions tighten, export-led economies experience immediate pressure on valuations and foreign liquidity. India can also face short-term foreign portfolio selling during these episodes. However, domestic institutional investment in India provides a structural buffer. Domestic mutual funds in India recorded net inflows of $1.7 billion in September 2023, helping absorb foreign selling.
Investors should check whether their portfolio relies on the assumption that all Asian markets move together. Prolonged periods of high interest rates test corporate balance sheets. Companies with large US-dollar debt loads face higher interest expense when dollar rates stay elevated.

Vestmind's view
We believe that cross-border market correlations during US interest rate cycles stem mainly from global dollar liquidity shifts rather than local corporate fundamentals. When the US Federal Reserve raises interest rates, global risk capital returns to US dollar assets. Overseas institutional funds trim exposure across emerging stock markets to meet higher yield hurdles in safer dollar assets.
Our position would be proven wrong if emerging market equities sustain an independent upward trend while the US Federal Reserve maintains elevated interest rates. Specifically, if foreign portfolio inflows into Asian equities expand continuously while US ten-year Treasury yields remain above 4.5 percent, our view that global liquidity dictates regional capital flows would require revision.
What to watch next
Track monthly foreign portfolio investment numbers published by central depositories in Seoul, Taipei, and Mumbai. These reports show whether global capital is returning to regional markets or exiting them.
Monitor the US ten-year Treasury yield, which stood above 4.5 percent in late 2023. Moves in this benchmark rate influence global portfolio allocations directly.
Observe foreign exchange reserves held by regional central banks. The Bank of Korea held $414 billion in foreign reserves in September 2023. When central banks use reserves to support local currencies, domestic monetary conditions tighten further. That tightening adds valuation pressure on domestic equity markets.
