Interest rates will rise to compensate investors both for having to accept a larger share of government bonds in their portfolio and for an increasing risk that governments will be tempted to inflate away the value of their debts, or even default.
利率的升高主要有来自两个方面：一是补偿对投资人大量持有政府债券。二是补偿国债通货膨胀后的损失，以及违约偿还的风险。
