SINGAPORE, April 7 (Reuters) -
Japanese rubber futures logged their steepest daily drop in over four years on Monday as U.S. President Donald Trump's fresh tariffs kicked in, further widening a global trade war and denting demand prospects.
The Osaka Exchange (OSE) September rubber contract JRUc6, 0#2JRU: ended morning trade 26.7 yen lower, or 8.33%, at 294 yen ($2.02) per kg, posting its biggest daily drop since November 4, 2020.
The contract plunged to 291.9 yen earlier in the session, its lowest since February 21, 2024.
The May rubber contract on the Shanghai Futures Exchange (SHFE) SNRv1 slid 995 yuan, or 6%, to 15,580 yuan ($2,132.46) per metric ton.
The most active May butadiene rubber contract on the SHFE SHBRv1 plunged 945 yuan, or 7%, to 12,555 yuan ($1,718.43) per metric ton.
