Some interesting information, but not as detailed as it could be. You need to load one of the region definitions from Tracker File > Import Region-Base Definitions Select from the dialog box the folder "region-mappings", and then One of the region definitions. I use Kull_Regions_v131a, I believe. This will split your bases into regions and give you a better idea of what is going on with your economy.
From your strategic map it appears you do not have the land bridge from Singapore to Fusan. This means you have to move everything by sea, mostly. So, what you end up with is TFs moving raw materials (Fuel, Oil, and Resources) from Singapore and other large ports to the Home Islands. It does appear that the Allies are putting the squeeze on your in Thailand/Malaysia. This will have an impact on some of your shipping.
Looking at your WiTP:AE Chart you have only 1949 HI producing, I guess that is why you are asking for help. You also only have 188 HI in reserve. You should have upwards of a million, yes, that is a 1 with 6 zeros after it in reserve by now. What to do? Cut off your shipyards for now, that will save you 6573 HI in demand. Turn your armaments off for now, you have nearly a quarter million points in reserve. This will save you another 3720 for a total of 10,293 HI. This will allow you to start building a surplus of 1400 or so a day.
As for aircraft production, the chart you have there is not complete, so I can only see a fraction of your production. You have a small pool of aircraft (278). This should be larger. The more aircraft you have the easier it is to blunt the allied spear as it thrusts towards you.
As for the spoilage at the bases, check your supply demands on those bases. You may have them set to stockpile supply and are spoiling that increased supply level. Also, try setting a larger base that has unlimited supply capability to stockpile and draw some of that supply from those bases.
Medan has a lot of fuel that should be going to Singapore.
Others have any ideas?
