本周，我们的封面将关注世界经济面临的威胁，过去一年的表现甚至令最乐观的预期也感到困惑。仅在一年前，所有人都认为高利率将很快导致经济衰退，但这些预期并未实现。在全球范围内，通货膨胀率正在下降，失业率大多保持在较低水平，大型中央银行可能已经停止了货币紧缩政策。不幸的是，这种成功不可能持久：利率看来仍将居高不下，消费者在大流行病期间积累的超额储蓄终将耗尽，各国政府还有高额债务需要偿还。展望未来，威胁重重。
THIS WEEK our cover looks at the threats facing the world economy, which has confounded even the most optimistic expectations with its performance over the past year.

Around the world, inflation is falling, unemployment has mostly stayed low and the big central banks may have stopped their monetary tightening. Unfortunately, this success cannot last: interest rates look set to remain high, consumers’ excess savings—accumulated during the pandemic—will eventually run out and governments have towering debts to service. Peer ahead, and threats abound.
