Bonds & Interest Rates

1. The relationship between interest rates and bond prices

This is a cornerstone of macro-finance:

• Bonds pay fixed coupons. If you buy a 10-year Treasury at 2%, you’ll keep receiving 2% on the face value until maturity.
• When market interest rates rise, new bonds are issued with higher yields. Suddenly, your old 2% bond is less attractive compared to a new 5% bond.
• To make your old bond competitive, its price falls in secondary markets.
• Conversely, if interest rates fall, old bonds with higher coupons become more attractive, and their prices rise.

🔑 Rule of thumb: Interest rates up → bond prices down (and vice versa). The longer the bond’s maturity, the more sensitive its price is to rate changes (this is called duration risk).

2. The Silicon Valley Bank (SVB) vignette

SVB (collapsed March 2023) is a case study in misunderstanding different types of risk.

What happened:

• SVB parked a massive share of deposits (short-term liabilities) into long-dated Treasury and mortgage-backed securities (long-term assets).
• When interest rates rose sharply in 2022–2023, the market value of these bonds plunged.
• If SVB could have held the bonds to maturity, no problem — they’d get full value back.
• But depositors (startups, VCs) demanded their cash back quickly (a liquidity shock).
• To meet withdrawals, SVB had to sell those bonds at a loss → realized huge losses → panic → bank run → collapse.

3. What risks were present?

1. Interest Rate Risk (duration risk):
• They held long-term bonds whose value was very sensitive to Fed rate hikes.
• They failed to hedge this with derivatives or asset-liability management.
2. Liquidity Risk:
• Their deposits were highly concentrated in venture-backed startups.
• When confidence cracked, withdrawals spiked, and they didn’t have cash on hand.
3. Concentration Risk:
• Customer base wasn’t diversified — mostly tech/startups with correlated behavior.
4. Reputational/Confidence Risk:
• Banking is fragile; once word spread, even solvent banks can fail if withdrawals accelerate (classic Diamond–Dybvig model).

4. What they should have better thought of

• Hedging: They should have used interest rate swaps or shorter-duration assets to protect against rate increases.
• Liquidity management: Keep more high-quality liquid assets (short-term Treasuries, cash-like instruments).
• Deposit diversification: Fewer concentrated depositors, more retail/insured deposits.
• Stress testing: Consider extreme but plausible scenarios (Fed hikes by 500bps in 18 months) instead of assuming the low-rate environment would persist.

📌 Takeaway lesson:

SVB wasn’t a credit-risk failure (the Treasuries were safe), it was a duration + liquidity failure. They confused “safe assets” with “safe balance sheet.” A bond that’s guaranteed to pay at maturity can still sink a bank if it has to be sold early at a loss to meet withdrawals.

2×2 Framework of Banking Risks

. What the chart shows

• The Fed Funds rate (red dotted line) is the main policy rate.
• The Interest on Excess Reserves (IOER) (blue line) is effectively the floor of rates: banks won’t lend below this because they can earn that risk-free from the Fed.
• The Discount Window rate (gray line) is the ceiling: banks in crisis can always borrow at this rate.
• Together, these form a corridor system for short-term rates.

From March 2022 to mid-2023, the Fed hiked by 550 basis points (5.5%), one of the fastest increases in modern history.

2. Why raising rates matters

When the Fed hikes:

• Borrowing costs rise → mortgages, car loans, business loans all get more expensive.
• Asset prices fall → as we discussed with bonds, higher rates push bond prices down, and even equities get repriced.
• Consumption/investment slow → housing, durable goods, and business capex are highly interest-sensitive.
• Labor markets cool → firms invest and hire less aggressively.

That’s the transmission of monetary policy the slide notes.

Excellent question — quantitative easing (QE) is one of those things that sounds mystical (“printing money”) but is really a specific, rule-based tool. Let’s go step by step so you can explain it like a Fed economist.

1. What is Quantitative Easing?

• Definition: QE is when a central bank (like the Federal Reserve) buys large quantities of longer-term financial assets (usually government bonds, mortgage-backed securities) to push down long-term interest rates and stimulate the economy.
• It’s called quantitative because it targets the quantity of assets purchased, not just the short-term policy rate (the Fed Funds rate).
• It’s used after the Fed has already cut short-term rates to zero (the “zero lower bound”), and still wants to add stimulus.

So: QE is basically “non-traditional monetary policy” used when traditional rate cuts aren’t enough.

2. Where does the Fed’s power come from?

• Legal authority: Congress created the Federal Reserve in 1913, and it has the power to conduct open market operations (buying/selling securities). QE is just a much bigger and longer-duration version of that.
• Operational ability: The Fed can create reserves (“money”) electronically. When it buys a bond from a bank, it credits that bank’s reserve account at the Fed. That’s new money in the system.
• Credibility: Investors believe in QE because they believe the Fed can and will buy in large scale — that expectation alone lowers yields.

So the “power” comes from the Fed’s legal mandate + its monopoly on creating central bank reserves.

3. What are the effects of QE?

Think of the effects in layers:

(a) Direct effect (portfolio channel):

• By buying long-term bonds, the Fed drives their price up and their yield down.
• This lowers borrowing costs for mortgages, business loans, and other credit tied to long-term rates.

(b) Liquidity effect:

• QE injects reserves into banks, making the financial system flush with cash.
• That reduces fears of credit freezes (like in 2008).

(c) Expectations effect (signaling channel):

• QE signals the Fed is committed to keeping rates low for a long time.
• This shapes investor expectations and can anchor long-term yields even more.

(d) Wealth effect:

• By raising asset prices (stocks, bonds, housing), QE can boost household wealth, which may encourage spending.

4. Risks and Critiques

• Asset bubbles: By pushing investors into riskier assets, QE can inflate stock or housing bubbles.
• Inequality: Asset owners benefit more, so wealth gaps can widen.
• Diminishing returns: The more QE you do, the less powerful each round becomes.
• Exit challenges: Unwinding (quantitative tightening, QT) can be destabilizing.

5. Real-world examples

• 2008–2014: Fed did QE after the financial crisis, buying ~$4.5 trillion in bonds.
• 2020 pandemic: Another massive QE, stabilizing markets when COVID froze credit.
• Both times, it helped prevent deflation and deep recession, though critics argue it fueled inequality and asset inflation.

📌 Summary for class:

QE is the Fed’s way of stimulating the economy when short-term rates are already at zero. It works by buying long-term bonds, lowering yields, and signaling commitment to easy policy. Its power comes from the Fed’s legal mandate and its ability to create reserves. It supports growth and prevents financial freezes, but carries risks of bubbles, inequality, and tough unwinds.

👉 Do you want me to also sketch how QE fits into the broader “Monetary Policy Toolkit” (rate cuts → forward guidance → QE → credit facilities), so you can explain how it sits alongside traditional interest rate policy?

This is a rich, PhD-level topic — you’re asking about the global role of the dollar, the work of Kenneth Rogoff (and others like Eichengreen, Obstfeld, and Krugman), and what might cause a break in the system. Let’s go carefully, building layer by layer.

1. Why being “denominated in dollars” is beneficial

When global trade, finance, and reserves are denominated in U.S. dollars, several benefits accrue:

• Transaction convenience: If everyone uses the same currency, there’s less friction. It reduces exchange rate risk for firms invoicing globally.
• Liquidity & depth: U.S. Treasury markets are the deepest and most liquid in the world. This makes dollars the safest and easiest asset to hold and transact in.
• Stability: Dollar assets are perceived as safe stores of value, especially in crises (the “safe haven” effect).
• Lower borrowing costs: Because of global demand, U.S. borrowers (government and private) enjoy lower interest rates — a form of “exorbitant privilege” (term coined by Valéry Giscard d’Estaing, and emphasized by economists like Gourinchas and Rey).

2. Kenneth Rogoff’s work on dollar dominance and the “preeminence premium”

• Rogoff and others argue that the U.S. dollar enjoys a dominant currency advantage beyond what fundamentals alone would dictate.
• This “premium” arises from:
• Network effects: Once everyone uses dollars, the cost of switching to another currency is high.
• Policy credibility: U.S. institutions (Fed, rule of law, contract enforcement) reinforce trust.
• Financial infrastructure: Most global payments, invoicing systems (SWIFT, CLS), and contracts are dollar-based.

Rogoff’s broader point: the dollar is overrepresented relative to U.S. GDP share in the global economy — about 60% of reserves, 40–50% of trade invoicing, while the U.S. is ~25% of world GDP. That’s the “preeminence premium.”

3. Why do other countries use the dollar?

• Invoicing & trade: Oil, commodities, and manufactured goods are typically invoiced in dollars. This reduces bilateral risk when trading with multiple partners.
• Reserve holdings: Central banks hold dollar reserves to stabilize their own currencies in crises.
• Dollar-denominated debt: Emerging markets issue debt in dollars to attract global investors who trust dollar-denominated contracts more than local currency ones (this is the classic “original sin” problem).

In short, the dollar is the global “unit of account, medium of exchange, and store of value” — a rare triple dominance.

4. What could upset this dominance?

Three main channels could erode dollar supremacy:

1. Loss of trust in U.S. institutions: If U.S. defaults on Treasuries (e.g., debt-ceiling crisis) or persistent inflation erodes credibility.
2. Geopolitical realignment: Rival powers (China, EU, BRICS) pushing alternatives — e.g., yuan-denominated oil contracts, euro’s role in regional finance.
3. Technological disruption: Widespread adoption of central bank digital currencies (CBDCs) or alternative payment systems that bypass SWIFT.

But each faces hurdles:

• Euro: large but fragmented fiscal union.
• Yuan: capital controls and lack of legal/institutional trust.
• Digital assets: volatility and lack of state backing.

So the dollar’s dominance is sticky because of network effects and institutional depth.

5. Historical shifts in global monetary anchors

There have been major transitions before:

• 19th century (Gold Standard): The pound sterling was the global reserve currency, backed by Britain’s trade dominance and financial depth.
• Interwar period: Sterling lost ground after WWI; dollar began to rise as U.S. economy overtook Britain.
• Bretton Woods (1944–1971): Dollar formally pegged to gold; other currencies pegged to the dollar. Solidified U.S. dominance.
• Post-1971 (Nixon Shock): Gold link severed, but dollar dominance persisted because Treasuries became the “safe asset” of choice.
• Euro’s launch (1999): Some shift toward euro reserves, but eurozone crises capped its global role.
• Today: China pushes yuan internationalization (e.g., Belt and Road lending, CIPS payments system), but adoption remains limited.

6. Could we see a future shift?

• The biggest historical lesson (Eichengreen): reserve currency shifts are slow, tied to deep changes in economic size, credibility, and financial markets.
• For the dollar to be displaced, you’d need both a viable alternative and a U.S. policy failure.
• The likeliest candidate is still the euro (if fiscal integration strengthens), or a long-term Chinese yuan (if capital controls are liberalized and institutions trusted).
• Another possible future: multipolar reserves (USD, EUR, RMB, maybe digital SDRs).

📌 Summary for class:

Being denominated in dollars is beneficial because it reduces transaction costs, provides liquidity, and lowers borrowing costs through what Rogoff calls a “preeminence premium.” Other countries use it because of trust, network effects, and depth of U.S. financial markets. Dollar dominance could be upset by U.S. mismanagement, geopolitical shifts, or technological disruption, but history shows reserve currency transitions are slow and rare. The last big shift was sterling to dollar in the early 20th century; the next may be multipolar rather than a single challenger.

👉 Would you like me to make you a timeline exhibit (Sterling → Dollar → Bretton Woods → Floating Dollar → Today) so you can visualize how rare and slow these currency shifts really are?
