Translation: Banks are in trouble, the economy is in trouble, and Trump wants to artificially prop up the economy long enough to get reelected. He's attempting to make it sound as if it's for exports, but it's really to save the financial system. He's concerned.
If the Fed prints money to buy bad loans or other poor performing securities to rescue banks, it's called QE. If you or I print money to buy anything, it's called counterfeiting.
The Fed is dumping a fuck-ton of money into the economy and with low/negative interest rates, it is forcing banks to lend it essentially free instead of parking it somewhere. Big money is currently hoarding cash/liquid assets because they currently think it's better to take a hit on inflation than loan defaults and/or big market losses coming down the pike. That could be why there is no money in the repo (repurchase agreement) market, but I'm no expert. It's akin to a bank walking into a pawn shop and saying they need $10,000 to give out in loans that they will repay tomorrow with interest, and using a brand new corvette as collateral. They pawn shop (lending bank) says, "That's a fantastic deal, but we have no money to give you." Things are in danger of coming to halt until the Fed shows up at the pawn shop and hands over a warm stack of freshly printed $100 bills just to keep all interested parties' businesses from tanking.
This new money will take a minute to circulate through the financial system, and when it starts hitting the pockets of the average wage-earner, the price of everything will soar. The purchasing power of your nest egg in the bank falls dramatically. The average person will have less discretionary spending because they'll be spending earnings on the ballooning prices of milk, bread, utilities, healthcare, car payments, student loan payments, credit card payments, and mortgages. When money gets tight and cards are maxed, less consumer goods are purchased and loan payments slow. Borrowers default and it's 2007-8 again, but with multiple bubbles. Your savings and cash accounts are devalued, and your retirement/401K is crushed. Tax revenue shrinks while the Federal Government continues to spend $1 Trillion more (and growing) per year than it receives.
The only question is: "How long?"
