BOJ, CPI, and my MXNJPY / ZARJPY watch

Japan's CPI coming in hotter than expected for February has me revisiting my thesis on $MXNJPY and $ZARJPY. The BOJ seems to be hinting at tightening, yet these carry trades are still grinding higher today with $ZARJPY at 9.841 and $MXNJPY at 9.26. Wondering how long this can run before a more definitive pivot shakes things up.
