Asian bonds record biggest monthly foreign outflow since March 2020

The brief

A foreign outflow from Asian bonds means overseas investors reduced their holdings by selling more bonds than they purchased. “Net” matters because it measures sales after purchases are deducted. A positive outflow therefore signals that international money is leaving those bond markets. It can reveal changing investor confidence and affect financial conditions. In September, foreigners sold a net $8.21 billion of bonds in India, Indonesia, Malaysia, South Korea and Thailand. The selling came as US Treasury yields rose sharply and expectations grew that the Federal Reserve and other central banks would keep raising interest rates. Investors also pulled about $23.49 billion from regional equities. The outflow shows a broad retreat from Asian assets, not a single-country event. ANZ’s Khoon Goh linked the weakness to a more cautious global risk environment, rising global bond yields and elevated oil prices. The article does not state the longer-term effects on each country.

What does a foreign outflow from Asian bonds mean?

A foreign outflow from Asian bonds means overseas investors reduced their holdings by selling more bonds than they purchased. “Net” matters because it measures sales after purchases are deducted. A positive outflow therefore signals that international money is leaving those bond markets. It can reveal changing investor confidence and affect financial conditions.

02

How large was the outflow, which countries were affected, and how did it compare with the March 2020 sell-off?

The September outflow totaled $8.21 billion across bonds in India, Indonesia, Malaysia, South Korea and Thailand. It was the region’s heaviest monthly foreign bond selling in more than six years. The figure shows that international investors were pulling money from several Asian markets at the same time, rather than targeting only one country.

South Korea recorded the largest withdrawal, at about $6.3 billion. Thailand followed with $822 million, India with $548 million, Malaysia with $436 million and Indonesia with $100 million. These figures add to the article’s picture of broad-based selling across regional bond markets.

September’s outflow was the largest since March 2020, when investors sold $17.28 billion. That earlier withdrawal was about $9.07 billion larger, or more than twice September’s amount. The article links the latest pressure to higher US yields and renewed Fed tightening.

03

Why did rising US Treasury yields and expectations of further Federal Reserve rate hikes make Asian bonds less attractive to international investors?

US Treasury yields influence global investment choices because Treasuries are widely used as a benchmark for borrowing costs and returns. When their yields rise, investors may demand higher returns from Asian bonds to justify taking on additional market and currency risk. If Asian yields do not rise enough, those bonds can look relatively less attractive.

In September, the US 10-year Treasury yield surged 53.5 basis points and reached 5.3645%, its highest level in 24 and a half years. The Federal Reserve also raised interest rates and signalled more increases. Those developments made global bond yields rise and encouraged investors to reduce exposure to emerging-market debt.

The article links the move to concerns that high oil prices could fuel inflation, prompting further rate hikes by major central banks. ANZ’s Khoon Goh described the resulting weakness as broad-based and tied to a more cautious global risk environment.

04

What can happen to Asian currencies, borrowing costs, and economic growth when foreign investors sell large amounts of local bonds?

When foreign investors sell large amounts of local bonds, demand for those bonds falls. The sales may also involve converting local currency into foreign currency, which can put downward pressure on the local currency. A weaker currency can make imported goods and energy more expensive, potentially adding to inflation. These are general financial-market effects, not outcomes reported in this article.

Bond prices generally fall when investors sell heavily, pushing yields higher. Governments and companies may then face higher borrowing costs when issuing new debt. Banks and other borrowers can also face tighter financial conditions. In extreme cases, investors become more cautious across stocks and bonds, as the article observed across regional assets.

The article records about $8.21 billion leaving regional bonds and about $23.49 billion leaving equities. It does not state how currencies, borrowing costs or growth changed afterward. The forward risk is that sustained outflows could make financing more expensive and reduce investment and economic activity.

05

Why did South Korea experience the largest bond outflow among the countries listed in the article?

South Korea experienced the largest bond outflow among the five markets listed, with foreign investors selling about $6.3 billion in September. That amount was far above Thailand’s $822 million and the smaller withdrawals from India, Malaysia and Indonesia. The figure identifies the scale of Korea’s selling, but not the precise reason for its size.

The article gives a regional explanation rather than a South Korea-specific one. Higher US Treasury yields, renewed Federal Reserve tightening and rising global bond yields reduced investors’ appetite for emerging-market debt. Elevated oil prices also raised concerns about inflation and further interest-rate increases by major central banks.

The article notes that South Korea’s September sales were the country’s largest monthly net outflow since $7.25 billion was sold in March. It does not identify a particular Korean policy, economic event or investor group that caused the larger withdrawal. Any more specific explanation would go beyond the supplied evidence.

06

Why does the US 10-year Treasury yield influence investment decisions and bond markets around the world?

The US 10-year Treasury yield matters because US government debt is central to global financial markets. Investors use its yield as a reference point when comparing returns on other bonds. It also influences borrowing costs across economies. A higher Treasury yield can make assets elsewhere appear less rewarding unless their returns rise enough to compensate for added credit, currency or political risk.

The article gives a clear example. The 10-year yield jumped 53.5 basis points in September and reached 5.3645%, a 24-and-a-half-year high. At the same time, the Federal Reserve raised rates and signalled further increases. Those moves lifted global bond yields and reduced demand for emerging-market debt.

That benchmark effect helps explain why selling spread across India, Indonesia, Malaysia, South Korea and Thailand. Investors were responding to a wider global change, not simply to local conditions. The article describes the result as a more cautious risk environment and reports simultaneous regional equity outflows.

07

What is a bond, and why do bond prices generally fall when yields rise?

A bond is a financial claim created when an investor lends money to a government, company or other issuer. The issuer promises interest payments and repayment of the principal at a specified time. Bonds therefore provide funding for the borrower and an income-producing investment for the buyer. The supplied article discusses bonds but does not define them.

Bond prices and yields usually move in opposite directions. If market interest rates rise, newly issued bonds can offer higher payments. Existing bonds with lower fixed payments become less attractive, so their market prices generally fall until their effective yield becomes competitive. Conversely, falling yields can make older bonds with higher payments more valuable.

This relationship helps explain the article’s selling pressure. The US 10-year Treasury yield surged 53.5 basis points in September, while investors withdrew $8.21 billion from five Asian bond markets. Higher global yields made existing or lower-yielding emerging-market debt less appealing relative to other opportunities.
