The economy is near collapse just a sign its rapture is very near. Jesus said before rapture it will be like the days of Noah & Lot " THEY BOT AND SOLD " lUKE 17:

²⁸ Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;

²⁹ But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.

Only after Lot left was there destruction and economy fell. Look at the import and exporting ships out at sea near USA/Babylon watching Babylon get destroyed by fire only then do they cry that the  import and exporting business the economy is gone. Notice if there was a East Coast Tsunami before there would be no city for the sea captains to drop their goods, nor would there be ships out at sea near sea port!

Revelation 18

​3. " the merchants of the earth are waxed rich through the abundance of her delicacies." 9.  And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning, 11. And the merchants of the earth shall weep and mourn over her; for no man buyeth their merchandise any more: 15. The merchants of these things, which were made rich by her, shall stand afar off for the fear of her torment, weeping and wailing, 17.For in one hour so great riches is come to nought. And every shipmaster, and all the company in ships, and sailors, and as many as trade by sea, stood afar off, 18." And cried when they saw the smoke of her burning"

Babylon gets nuked, rapture happens, then Economy collapses, later Tsunami comes. Back then things were cleansed by fire 1^st then by water.  water was mixed with the ashes of a red heifer to make cleansing water.  Since people are the temple of God could the ashes of the burned from the thermal explosion mixed with ocean water make Lustral water for cleansing?

Numbers 31:23 Everything that may abide the fire, ye shall make it go through the fire, and it shall be clean: nevertheless it shall be purified with the water of separation: and all that abideth not the fire ye shall make go through the water.

After this event a Great multitude of people in heaven celebrating the wedding day of the Lamb they shout about Babylon the great harlot's destruction i believe these people are raptured after the nukes came down on Babylon.

Rev19:3 And again they shouted: “Hallelujah! The smoke from her goes up for ever and ever.”

7. Let us rejoice and be glad
    and give him glory!
For the wedding of the Lamb has come,
    and his bride has made herself ready.
