The Japanese yen surged to 148.3 per dollar on Friday from the four-month low of 150.9 touched earlier in the session after weak labor data in the US triggered a slide in the greenback. In the meantime, US President Trump today enforced tariffs of 15% on Japanese goods following the trade deal that lowered US tariffs from 25%. Trump reaffirmed a 10% global tariff and introduced steep reciprocal levies of up to 41% on countries without finalized trade deals, along with a 40% tariff on transshipped goods. Meanwhile, the Bank of Japan kept interest rates unchanged on Thursday but raised its inflation forecast for the current fiscal year. Policymakers maintained a cautious tone, citing expectations of a temporary dip in underlying inflation and heightened uncertainty over global trade risks.
