在金融领域，"crash" 指的是资产价格（如股票、债券、商品等）的急剧、突然且通常是大幅的下跌。这种下跌通常是由于广泛的恐慌或投资者信心的突然丧失导致的，而不仅仅是基于经济或财务基本面的变化。

Investopedia给该词的释义如下：

A crash is a sudden and significant decline in the value of a market. A crash is most often associated with an inflated stock market, though any market can crash, for example, the international oil market in 2016. In the U.S., a crash is determined by a precipitous drop in the value of market indexes, primarily the Dow Jones Industrial Average (DJIA), the S&P 500, and the Nasdaq.

参考译文：crash是市场价值突然和显著地下降。crash最常与股市过度膨胀相关，尽管任何市场都可能发生crash，例如2016年的国际石油市场。在美国，通过市场指数的急剧下跌来确定crash，主要是道琼斯工业平均指数（DJIA）、标普500指数和纳斯达克指数。

Crash在中文表达中可以译为“崩盘”。如

The housing bubble's burst in 2008 led to a major financial crash, affecting banks and institutions globally.

2008年房地产泡沫的破裂导致了一次重大的金融崩盘，影响了全球的银行和金融机构。

In 2016, oversupply concerns caused the international oil market to crash, with prices reaching historic lows.

2016年，由于供应过剩的担忧，国际石油市场崩盘，价格达到历史最低点。

Regulatory bodies have implemented measures to prevent crashes, such as trading halts when stock indexes fall beyond a certain point within a trading day.

监管机构已实施了预防崩盘的措施，例如当股票指数在交易日内跌破某一点时，暂停交易。
