Why this can crash the market
A fast-rising dollar tightens conditions everywhere at once. Much of the world borrows in dollars, so a stronger dollar raises the cost of every foreign loan. At home, a large share of S&P 500 revenue is earned abroad and converts back into fewer dollars, so earnings get marked down even when business is fine.
