US interest rate hikes in 2022 have drawn global capital away from the rest of the world to put downward pressure on currency values vis a vis the dollar. To defend their exchange rates, many Asian central banks have sold off reserves. A future post will provide an overview of the situation as data become more broadly available. For Taiwan, data already in hand reveal a surge in capital outflows. For the first half of 2022, net portfolio outflows reached $77 billion versus average full-year magnitudes hovering around $60-80 billion for most of the past decade. Even in the context of a rush of global capital out of emerging markets, the Taiwan case is extreme. Nevertheless, a modest accumulation of official reserves has continued to prevail on the balance of payments.
