It seems an improvement of the situation from before...I think it was 84 billion or so couple months earlier.
Yah but this is standard feature of any country with persistent current account deficit (same kind of thing with India).
Everything in forex in this situation basically comes from capital account essentially ....because foreign loans, bonds and foreign investments have to be changed to local currency for use within country and central bank retains the forex since its the local currency guarantor/exchanger etc.
So subtracting foreign debt and foreign holdings etc is going to give a 0 figure since thats exactly the only thing that is showing up as foreign reserve in first place.
When there is current account surplus, you will have "net reserve" that is positive as the country essentially has surplus forex coming by trade and service transactions.
Though it depends on the definitions being used for this stuff given Capital + Current account should theoretically add to zero in any case.
