Mohammad Beg's tenure saw an economic decline, mainly caused by Abbas' costly campaign to Kandahar and the scarcity of raw materials for the silk trade. Notwithstanding of his long-standing economical experience, Mohammd Beg could not come up with a solution to the immoderate outlay on the court and the expensive investment on the army, and put the state's income into further decline with enhancing centralisation, a process that could not be supported by New Julfa's trade network.
