• Reclaimed the 1.1800 status amid the softer dollar and with German Chancellor Merz anticipating the SCOTUS ruling to lower the tariff burden on the German economy, while French Trade Minister Forissier said he is in talks with EU counterparts regarding tariffs and that the EU has the tools to retaliate.

GBP/USD: +0.3%

• Gradually edges higher after returning to 1.3500 territory, but with further upside limited as the UK is seen to potentially be among the countries negatively impacted by recent US tariff developments, given that the UK had previously negotiated a 10% tariff deal with the US.

USD/JPY: -0.5%

• Retreated beneath the 155.00 level amid the softer dollar and with a lack of support owing to the absence of Japanese participants for the Emperor's Birthday, while there were also recent comments from Japan's ruling LDP tax chief Onodera, who described the US tariff situation as a real mess.
