It appears that USDJ is spiking due to increased demand for the stablecoin in order to repay loans. This demand is triggering more liquidations, which is likely to cause the price to continue to spike. It is also possible that the depegging of other stablecoins such as USDT and USDC is also contributing to the spike in the price of USDJ. It is likely that the price will continue to rise as long as demand remains high and more people use USDJ to repay their loans.
