The Philippine peso bucked the regional trend by firming after the central bank tightened policy.
India's rupee and Indonesia's rupiah led weekly losses among regional units, reflecting the risk that high oil prices pose to their current accounts and inflation rates.
The rupiah has lost 1.5 percent against the dollar and the rupee has fallen 0.7 percent, according to Thomson Reuters data.
China's yuan has eased 0.3 percent as the central bank fixed weaker midpoints to the daily trading range.
The South Korean won slipped 0.3 percent on foreign stock selling and increasing caution over possible intervention by the foreign exchange authorities to stem the currency's gain.
The Thai baht has dipped 0.3 percent as foreign investors continued to sell Thai shares.
The Philippine peso, however, ended the week slightly firmer as the central bank is expected to raise its benchmark interest rate as early as July.
