字幕依据：But big money, global investors didn't want to just buy up my mortgage, and Stan's mortgage. It's too much hassle to deal with us as individuals. Instead, they bought investments called mortgage backed-securities. Mortgage backed-securities are created when large financial institutions securitize mortgages. GPOv72Awo68@2:21
字幕依据：Eventually, some institutions even started using what are called predatory ending practices to generate mortgages. They made loans without verifying income and offered absurd, adjustable rate mortgages with payments people could afford at first, but quickly ballooned beyond their means. GPOv72Awo68@3:38
字幕依据：Actually, let's go to the Housing Bubble. Rapid increases, driven by irrational decisions. Well, this was a bubble, and bubbles have an annoying tendency to burst. People just couldn't pay for their incredibly expensive houses, or keep up with their ballooning mortgage payments. GPOv72Awo68@4:52
字幕依据：There was another financial instrument that financial institutions had on their books that exacerbated all of these problems--unregulated, over-the-counter derivatives, including something called credit default swaps, that were basically sold as insurance against mortgage backed securities. GPOv72Awo68@5:55
字幕依据：In 1998, Hong Kong's overnight interest rates spiked to nearly 300% in a single day. Money markets went wild as the city's financial system hung in the balance. Just a few years earlier, billionaire George Soros had broken the Bank of England, pocketing a billion dollars by shorting the British pound. NKCl8gkBvTo@0:00
字幕依据：One by one, currencies across Asia crumble. The Thai Bart, Malaysian ringit, Indonesian rupia, Philippine peso, and South Korean one plunge in value. Stock markets implode as foreign investors flee. Billionaire hedge funds, including George Soros's quantum fund, are feasting on the chaos, shorting Asian currencies and reaping huge profits. NKCl8gkBvTo@1:24
字幕依据：about seven times its money supply, an enormous war chest. But the peg also made Hong Kong a target. For years, Hong Kong's inflation was higher than America's, making its currency overvalued and exports pricey. Property prices and stocks had soared into bubbles during the boom. NKCl8gkBvTo@2:46
字幕依据：The peg fixed at 7.80 Hong Kong dollars equals1 US was seen as a bedrock of stability for trade and investment. China's government also stepped in with vocal support. Beijing promised it would not devalue the Chinese renbi which was a fear at the time and even offered Hong Kong use of China's vast reserves if needed. NKCl8gkBvTo@3:54
