Read this twice: 

" . . . is ready to deploy “unlimited” liquidity into financial markets if needed after President Yoon Suk Yeol lifted a martial law declaration he imposed overnight"

Why would a country need 'unlimited liquidity' if the thing that was done was un-done by the same guy who did the thing?

This is complete bullshit and shows that the legacy financial system is imploding at an exponential rate. It was never about North Korea. Their financial system is dying and they needed a "9/11 moment".
