:Caveat:
Since you did not share data with us therefore I've used a sample data, will help you to find month & year wise lowest (minimum) value.
How it works:
{=IFERROR(INDEX($O$2:$O$13,MATCH(0,COUNTIF($M$16:M16,$O$2:$O$13),0)),"")}
Finish the formula with Ctrl+Shift+Enter & fill it down.
{=IF(MIN(IF(MONTH($N$2:$N$13)=MONTH(N$16),IF($O$2:$O$13=$M17,$P$2:$P$13)))=0,"",MIN(IF(MONTH($N$2:$N$13)=MONTH(N$16),IF($O$2:$O$13=$M17,$P$2:$P$13))))}
Finish the formula with Ctrl+Shift+Enter & fill it across.
{=IF(MIN(IF(YEAR($N$2:$N$13)=YEAR(R$16),IF($O$2:$O$13=$Q17,$P$2:$P$13)))=0,"",MIN(IF(YEAR($N$2:$N$13)=YEAR(R$16),IF($O$2:$O$13=$Q17,$P$2:$P$13))))}
Finish the formula with Ctrl+Shift+Enter & fill it down.
