History points to Asian FX rally fizzling out
Non-Japan Asian (NJA) currencies have appreciated versus the US dollar and currencies of their main trading partners in October. But the historical pattern of monthly appreciation/depreciation suggests that this Asian currency rally may start losing steam in coming weeks, with currencies eventually weakening modestly versus the US dollar.
This historical pattern is partly due to the seasonality of current account flows, the ebb and flows of capital attracted/repelled by valuations and central banks’ management of their currencies. I see few reasons why it will be materially different this time round.
Inflows into Asia are unlikely to accelerate given lingering foreign investors’ concerns about regional and global economic growth, the start of the US Fed hiking cycle and country-specific vulnerabilities including sensitivity to commodity prices and elevated foreign debt.
Furthermore, while Asian central banks may not purposefully weaken their currencies, they may have the room and incentive to lean against further appreciation: overall, Asia inflation is low and falling, exports are weak and FX reserves have fallen in the past six months.
